Characterization of the Seed Oil and Meal from Monechma ciliatum and Prunus mahaleb SeedsJAOCS, Journal of the American Oil Chemists' Society, Aug 2009 by Mariod, Abdalbasit Adam, Aseel, Kawthar Mahmoud, Mustafa, Ali Abdalgadir, Abdel-Wahab, Siddig IbrahimAbstractThe oil and meal from Monechma ciliatum (black mahlab) and Prunus mahaleb (white mahlab) seeds were characterized for their physicochemical properties. The oil content was found to be 30.95 and 13.15% in white and black mahlab seeds, respectively. The refractive indices of white mahlab oil (WMO) and black mahlab oil (BMO) were 1.475 and 1.470, and specific gravities were 0.8511 and 0.8167 g/cm^sup 3^, respectively. Saponification values were 184.23 and 180.3 mg KOH/g, peroxide values were 2.54 and 4.43 meq/kg, and unsaponifiable matter was 0.92 and 0.66%, respectively. The major fatty acids were palmitic 4.5%, stearic 16.0%, oleic 47.3%, and linoleic 31.4% in BMO, while in WMO they were palmitic 5.7%, oleic 45.0%, and linoleic acid 47.0%. A moderate amount of tocopherols were found at 45.2 and 28.5 mg/100 g in BMO and WMO, respectively. Protein content was found to be 21% in black and 28% in white mahlab seeds. The total amount of amino acids in black and white mahlab seeds was found to be 783.3 and 1,223.2 mg/g N, respectively. The concentration (on ppm dry-weight basis) of major elements (Ca, K, and Mg) and of minor elements (Al, Pb Ni, Mn, Cu, Cr, Co, and Fe) was also determined in the meals.Keywords Amino acid * Fatty acid * ICP-MS * Mineral elements * Monechma ciliatum * Physicochemical properties * Prunus mahlabIntroductionRecently, researchers all over the world have been looking to discover new sources of oils. In Sudan many studies have been done looking at the utilization of wild plants as a source of unconventional oil and theirmaximum utilities as antioxidants [1-3]. One of these wild plants, considered among the plants of the future, is black mahlab (Monechma ciliatum), which is well known in Sudan and belongs to the family Acanthaceae. Black mahlab is an annual glabrous herb, 30-65 cm high [4], with simple leaves measuring about 4-7 × 1-2 cm [5]. Black mahlab (Monechma ciliatum) is a famous medicinal plant in western Sudan, especially in the Nuba Mountains and Gabel Mara area. The seeds are used as an effective laxative and contain a fixed oil that emits a sweet and pleasant odor. Its further used in traditional Sudanese fragrances, lotions, and other cosmetics used for wedding preparation and childbirth [6]. In Botswana, Monechma ciliatum was believed to play an important role as a medicine for the remedy of general body pain, liver, and bowel trouble (diarrhea), as well as sterility in women [7]. The plant is used to induce labor and menses in Nigeria. It is also reported that the dried leaves are powdered and burnt as an inhalation for colds [8]. In Sudan, the dried entire plant is used for diarrhea, vomiting, and as a scent preparation. The seed oil content is 11.6% with iodine value of 69 and saponification value of 175.16; the fatty acid composition is 20.2, 17.3, and 17.9% for oleic, linoleic, and arachidic acid, respectively [9, 10]. Previous study by Uguru and others [5] showed that the hot methanol extract of the leaves of M. ciliatum has potent oxytocic property in vivo and in vitro, thus justifying its use in traditional medicine.White mahlab (Prunus mahaleb) is a deciduous tree, 1-2 m high, with many spreading branches; the bark is smooth and mahogany red. The leaves, which are up to 6 cm long, are bright green, shiny, oval, and finely toothed [H]. The white mahlab tree is a member of Rosaceae family, subfamily Prunoideae. The kernels of white mahlab seem to contain only small amounts of cyanogenic glycosides, but coumarin derivatives have been found. From the seeds, a fixed oil can be extracted that contains unusual conjugated linolenic fatty acid [12]. In Sudan, white mahlab is used in wedding preparations by crushing the seeds to manufacture traditional fragrances and lotions such as Dilka, Khumrra, and Darira. Also eating soaked white mahlab seeds is a remedy used for diarrhea in children. White mahlab is collected in Turkey and exported on a large scale. It is used in Turkey as a tonic or an antidiabetic in folk medicine and as a flavoring agent in making pies and candies. The white mahlab kernels form an important source of protein (30.98%) and fatty oil (40.40%). Its oil is also valuable in the preparation of lacquers and varnishes [12].Monechma ciliatum still grows as a wild plant in different areas in western Sudan states. No research data on its commercial production and its oil composition are available.Amino acid composition and protein digestibility measurements are considered necessary to predict accurately the protein quality of foods for human diets [13]. The widespread availability of vegetable oils around the world has resulted in the development of other oil-bearing plant species being neglected [14]. This study investigates the physicochemical and compositional properties including amino acids, minerals, trace elements, and fatty acids of seeds of the two mahlab plants, and a sensory evaluation of the oils obtained from these seeds is performed.Materials and MethodsSamples, Solvents, and ReagentsAll solvents used were of analytical grade. n-Hexane, methanol, chloroform, and petroleum ether were obtained from Prime for Scientific Services, Khartoum, Sudan. HCl, NaOH, HNO^sub 3^, and H^sub 2^O^sub 2^ were Suprapur grade (Merck, Darmstadt, Germany).Dried seeds of white and black mahlab were collected from a local market in Khartoum North, Sudan, then blended to obtain homogeneous samples, and pulverized before representative samples were taken for chemical analysis. For determination of the oven-dry weight, samples were dried at 105 °C for 24 h. Moisture and volatile matter in the samples were determined following a previously described method [15].Proximate Chemical AnalysisMoisture, lipid, ash, and crude-fiber contents were determined following the standard methods of the Association of Official Analytical Chemists [16]. The organic nitrogen content was quantified by the Kjeldahl method, and an estimate of the crude protein content was calculated by multiplication of the organic nitrogen content by a factor of 6.25 [17]. The two different samples were analyzed in triplicate. Total carbohydrate content was calculated from the difference, applying the formula:100% - (% protein % lipid %ash %fiber)Mineral AnalysisTwo replicate aliquote (500 mg) from each of the dried, powdered plant specimens were weighed, then wet-ashed by refluxing overnight with 15 mL of concentrated HNO^sub 3^ and 2.0 mL of 70% HClO^sub 4^ at 150 °C. The samples were dried at 120 °C, and the residues were dissolved in 10 mL of 4.0 N HNO^sub 3^-1% HClO^sub 4^ solution. The mineral content of each sample solution was determined by an Agilent Technologies 7500cinductively coupled plasma mass spectrometry (ICP-MS) system (Agilent Technologies, Wilmington, DE). Wavelengths used for the tested minerals were aluminum (Al) 396.152, calcium (Ca) 393.366, cadmium (Cd) 226.502, chromium (Cr) 206.149, cobalt (Co) 238.892, copper (Cu) 224.700, iron (Fe) 239.562, lead (Pb) 220.353, magnesium (Mg) 279.553, manganese (Mn) 257.610, nickel (Ni) 221.647, potassium (K) 766.490, and zinc (Zn) 213.856. The mineral contents of the samples were quantified against standard solutions of known concentrations, which were analyzed concurrently.Oil Extraction and DeterminationThe seeds were milled gently in a blender (Braun Multimix System 200, with Multimix deluxe grinder, MXK4 Germany), and oil was extracted by Soxhlet apparatus using petroleum ether 40-60 °C and determined following a previously described method [15]. The oil content was determined as a percentage of the extracted oil to the sample weight (w/w). The samples were analyzed in triplicate, then mean and standard deviation were calculated. The extracted oil was stored in a cold room (4 °C) in a dark glass bottle under nitrogen blanket for further analysis.Oil Physicochemical AnalysisFree fatty acids (FFA), iodine value (IV), saponification number (SN), peroxide value (PV), unsaponifiable matter, color, and refractive index (RI) were measured following a previously described method [15]. Color was determined using Lovibond Tintometer, Lovibond model E (Bicasa), suppUed by Griffin and Georgy, England, and refractive index was determined using an Abbe bench refractometer (model 46-315, England) with the temperature maintained at 30 °C. The analysis was done for the freshly extracted oils. The samples were analyzed in triplicate, then mean and standard deviation were calculated.Fatty Acid Composition by Gas Liquid ChromatographyThe fatty acid compositions of the seed oils were determined by gas liquid chromatography (GLC). The oils were converted to their corresponding methyl esters following a previously described method [15]. BF3/ methanol reagent (14% boron trifluoride) was used for methylation. GLC analysis of the fatty acid methyl esters (FAME) was performed using aHewlett-Packard HP5890 Series II gas Chromatograph (GLC) coupled to a flame ionization detector (FID) equipped with an Ultra 2 capillary column (25 m × 0.32 mm × 0.5 µm, 5% biphenyl and 95% dimethyl polysiloxane; Hewlett-Packard, Waldron, Germany), a split injector (split ratio 88:1), and an FID. The column temperature pro gram was 5 min at 150 °C, 10 °C/min to 275 °C, and 10 min at 275 °C. The injector temperature was 250 °Cwith a split ratio of 88:1. The carrier gas was hydrogen at a flow rate of 1.6 mL/min. The detector temperature was 280 °C with air and hydrogen flow rates of 460 and 33 mL/min, respectively. The fatty acid peaks were identified by comparing the retention times with those of a mixture of standard FAMEs (Sigma Chemicals, Deisenhofen, Germany). Each FAME sample was analyzed in duplicate.TocopherolFor determination of tocopherols, a solution of 250 mg of Monechma ciliatum and Prunus mahaleb oils in 25 mL ?-heptane was directly used for the HPLC. The HPLC analysis was conducted using a Merck-Hitachi (Tokyo, Japan) low-pressure grathent system fitted with an L-6000 pump, a Merck-Hitachi F-1000 fluorescence spectrophotometer (detector wavelengths for excitation 295 nm, for emission 330 nm), and a D-2500 integration system. The samples (20 µL each) were injected by a Merck 655-A40 autosampler onto a Diol phas e HPLC column (25 cm × 4.6 mm i.d.) (Merck) using a flow rate of 1.3 mL/min. The mobile phase used wasn-heptane/methy tert-butyl ether (MTBE) (99:1, v/v) [18].Amino Acid Composition by Amino Acid AnalyzerPreparation of Hydrolysate SampleThe content of dry matter and total N were determined according to procedures described by [16]. The content of amino acids (except for tryptophan) in defatted mahlab seeds was determined using Amino Acid Analyzer (L-8900 Hitachi-hitech, Japan) under the experimental conditions recommended for protein hydrolysates. Samples containing 5.0 mg of protein were acid hydrolyzed with 1.0 mL of 6 N HCl in vacuum-sealed hydrolysis vials at 110 °C for 22 h. The ninhydrine was added to the HCl as an internal standard. Hydrolysates were suitable for analysis of all amino acids. The tubes were cooled after hydrolysis, opened, and placed in a desiccator containing NaOH pellets under vacuum until dry (5-6 days). The residue was then dissolved in a suitable volume of a sample dilution Na-S buffer, pH 2.2 (Beckman Instr.), filtered through a millipore membrane (0.22-µm pore size) and analyzed for amino acids by ion-exchange chromatography in a Beckman (model 7300) instrument, equipped with an automatic integrator. Nitrogen in amino acids was determined by multiplying the concentration of individual amino acids by corresponding factors calculated from the percentage N of each amino acid [19]. The ammonia content was included in the calculation of protein nitrogen retrieval, as it comes from the degradation of some amino acids during acid hydrolysis [20, 21]. The ammonia nitrogen content was calculated by multiplying the ammonia content by 0.824 (N = 82.4% NH^sub 3^).Expression of ResultsThe composition of amino acids was expressed as milligrams per gram of N to estimate the quality of the protein in mahlab defatted seeds using the amino acid score pattern where amino acid ratio = (mg of an essential amino acid in 1.0 g of test protein/mg of the same amino acid in 1.0 g of reference prote in × 100). Nine essential amino acids were calculated by using a previously described method [13], where egg protein was used as reference protein.Sensory EvaluationPanelists were chosen to taste the two mahlab oils for characterization of their organoleptic properties (color, flavor, and taste). Oil samples were presented to the panelists in clear glasses at room temperature and in duplicate. The sensory analysis used was described in detail by Min [22]. Sensory qualities of the two oils were evaluated using a hedonic scale of 1-10, where 1 indicated the poorest flavor, color, and taste quality and 10 the highest organoleptic quality. The numerical results were then subjected to statistical analysis.Statistical AnalysisThe analyses were performed wi tìi three replicates. The mean values and standard deviation (mean ± SD) were calculated and tested using the Student's i-test (PResults and DiscussionProximate Chemical AnalysisThe proximate composition of the two mahlab seeds is given in Table 1. T he two samples showed significant differences (P ≤ 0.05) in all the analyzed constituents of the proximate composition except moisture content. The white mahlab seeds showed higher levels of lipid and protein content of 30.95 and 28.0 g/100 g, respectively, while black mahlab showed higher levels of fibers and carbohydrates content at 24.4 and 32.6 g/100 g, respectively. The results of oil content showed that white mahlab seed has a higher amount of oil (30.9 g/100 g) than the black mahlab seed (13.2 g/100 g). In 1981 Ayoub and Babiker [9] reported an oil content of 11.6% for black mahalb, which was higher than that reported in this study. Yücel [24] studied the seeds of Prunus mahaleb, and he found that die oil content ranged from 4.7 to 18.5 g/100 g, while Johansson et al. [25] mentioned that oil contents of Prunus mahaleb ranged from 12 to 16 g/100 g. The oilcontent of Prunus mahaleb in this study was higher than that found in these other studies.Oil Physicochemical PropertiesThe physicochemical properties of the two mahlab seed oils are shown in Table 2. Compared with Codex standards for crude vegetable oils [26], the white mahalab oil showed higher values for specific gravity, refractive index, acid value, peroxide value, saponification value, and unsaponifiable matter. Ayoub and Babiker [9] reported a lower saponification value (175.16) and a lower refractive index (1.4730) for black mahlab oil in comparison witìi me results in this study.From Table 2 it is instructive to note that the refractive indices for the white mahlab seed oil (1.475) and black mahlab seed oil (1.470) fall within the same range of 1.467-1.477 for grapeseed oil. The acid values for WMO and BMO of 7.8 and 7.3 mg KOHVg, respectively, were higher man the Codex standards for sunflower and ground nut oils, whilst the peroxide values for the WMO of 2.54 meq/Kg oil and for the BMO of 4.43 meq 02/Kg oil were less than that recorded for sunflower and ground nut oils in Codex standards. The percent unsaponifiable matter, shown in Table 2 for white mahlab (0.99%) and black mahlab (0.66%) seed oils, was less than that recorded for sunflower and ground nut oils in Codex standards [26].Sensory Evaluation of Black and White Mahlab OilTable 3 shows the results of the sensory evaluation for white and black mahlab oils. WMO oil scored more than 8 as overall score thus classifying the oil as better in color, odor, and taste. There was a significant difference (PFatty Acid CompositionThe fatty acid composition determined by GLC of the black and white mahlab oils is illustrated in Table 4. The major fatty acids in white mahlab seed oil were oleic (45.0%), linoleic (47.0%), and palmitic (5.7%). This result was higher than that reported by Yiicel [24], who reported 35.4, 28.5, and 4.6% for oleic, linoleic, and palmitic, respectively, in white mahlab seed oil. The major fatty acids in black mahlab seed oil were oleic (47.3%), linoleic (31.4%), stearic (16.0%), and palmitic (4.5%). This were higher than reported by Ayoub and Babiker [9] who reported 20.2, 17.3, and 12.5% for oleic, linoleic, and palmitic acids, respectively. They also reported 17.9% for arachidic acid, which was surprisingly not found in this study. The percentage of unsaturated fatty acids in white mahlab oil was 92.1%, while it was 79.9% in black mahlab oil. White mahlab oil was very richin both oleic and linoleic acid, while black mahlab oil was rich in oleic acid only.TocopherolThe tocopherol content of the oil from black and white mahlab seeds is given in Table 5. They had moderate amounts of tocopherols, 45.2 and 28.5 mg/100 g, respectively. The main tocopherol of the two samples wasγ-tocopherol, which represented 80.7 and 77.6% of the total, followed by a-tocopherol and δ-tocopherol, which represented 12.3 and 1.6 mg/100 g in BMO and 1.4 and 6.4 mg/100 g in WMO, respectively.Amino Acid ProfileThe amino acid profile of black and white mahlab seed, analyzed by amino acid hydrolysis, is presented in Table 6. The percentage ofsulphur-containing amino acids (methionine and cystine) in white mahlab seed was 3.9%, while in black mahlab it was 3.4% of the total amino acids, which was the lower than the other amino acids and was considered a reasonable amount for their important function in the cell processes in the oxidation and reduction system (cystine) and as a methyl donor (methionine) in metaboUsm. The total amount of the essential amino acids found in white and black mahlab seed was 623.8 and 454.8 mg/g N, respectively. The total aromatic amino acid levels (phenylalanine and tyrosine) found in white and black mahalab were 1 17.0 and 78.1 mg/g N, respectively. All the essential amino acids with the exception of tryptophan, which was not analyzed, were found to be present at low levels, and the total essential amino acids were found to be lower when compared to that of three different foods: broad bean (2740.0 mg/g N), wheat flour (1960.0 mg/g N), and soy flour (2,630.0 mg/g N) [27]. The total amount of the essential amino acids of white mahlab seed comprised about 50.9% of the total amino acids, which was less than that of black mahlab seed (58.0%).The chemical score suggested that the first limiting amino acid in black mahlab seed sample was methionine cystine followed by threonine, histidinen and isoleucine (Table 7). In the white mahlab seed sample, the chemical score suggested that the first limiting amino acids were threonine, methionine cystine, lysine, and isoleucine.Mineral CompositionMineral analyses are essential to guarantee the quality of any food product. ICP-MS aUowed us to determine the content of 13 minerals, many of which are required in human diets and others which are considered toxic.Table 8 summarizes the results of these analyses. Concentrations of major elements such as Ca, K, and Mg in white mahlab seeds (133.7, 204.2, and 102.2 ppm) were significantly (P <0.05)Table 8 also shows the content of potassium in black and white mahlab seeds was 204.2 and 80.53 ppm, respectively. Potassium plays an important role in human physiology, and sufficient amounts of it in the diet protect against heart disease, hypoglycemia, diabetes, obesity, and kidney disease. The content of magnesium in the studied samples (Table 8) was 102.2 and 69.13 ppm for BMS and WMS, thus providing 28.9 and 19.6% of the recommended dietary allowances [28], respectively. The concentrations of minor elements Al, Pb Ni, Mn, Cu, Cr, Co, and Fe levels were found at low levels in the studied samples.ConclusionsThe results reported here show that the seeds of two different species of mahlab plant collected in Sudan were different in their oil content and the physicochemical properties of that oil. Fatty acid composition was determined by GLC, and the major fatty acids were found to be 4.5% palmitic, 16.0% stearic, 47.3% oleic, and 31.4% linoleic in black mahlab oil. In white mahlab, the major fatty acids of me oil were found to be 5.7% palmitic, 45% oleic, and 47% linoleic acid. The amino acid profile of the defatted seeds as analyzed by amino acid analyzer indicated that the total amount of amino acids of black mahalb was 783 mg/g N and that of white mahlab was 1,223 mg/g N. The percentage of essential amino acids was 58.0% in black mahalb and 50.9% in the white mahlab. The results from sensory evaluation analysis of the two mahlab oils revealed that there was a significant difference (PAcknowledgements We thank Dr. B.

LESSON 1营养我们吃什么，以及我们如何确定我们吃营养状况的一个重要程度，并有外部和内部多种因素的影响。
谁的人要罚款的问题的答案：“我应该吃什么良好的营养？”很容易成为迷失在信息走廊迷宫，困惑由科学家提供的技术资料，由财富或提供简单的答案误导与产品销售[1]。
某处之间是合理的，常识性的信息，我们可以用它来指导我们的声音营养知识的追求。
首先，我们需要学习一些常用术语的定义和营养找出各种各样的指引，可帮助我们衡量我们的饮食质量和健康的饮食模式发展。
营养与食品：定义这个词往往是成对营养与食品一词，因为两者是相辅相成的。
它们是相互依存的，但不能互换。
食品可能被定义为任何提供营养物质，食用时饮用。
它是由许多天然成分的所有化学品的气味，如提供不同的功能了，味道，颜色和营养。
给我们的营养成分，被称为营养素。
这些营养素归类为脂肪，蛋白质，碳水化合物（糖和淀粉），矿物质，维生素和水。
他们被称为必需的营养素，因为我们不能让他们一直没有。
我们需要为他们的能量，为建立和维持人体组织，以及用于调节身体机能的三个食品在体内基本职能。
营养可能被定义为过程，我们得到了必要的营养，并利用它们让我们的身体许多其他物质需要，这个过程将包括饮食和消化食物，吸收和利用，或代谢，它含有的养分。
我们可以从食物中获得所有必需的营养。
但是，它可能获得不进食，消化食物，如果，例如，直接注入营养素如静脉营养静脉营养对我们的。
因此，它是所必需的营养素和食物，通常为他们提供[3]。
由于粮食是重要的，我们需要知道食物的，哪些是对各种营养素的最佳来源，成为一个健康的饮食营养如何结合他们的内容。
良好的营养一词意味着，我们从我们的食物都需要保持在我们的身体运作，并保持最佳的健康必需营养素的数额获得。
一个良好的营养非常简化的定义可能是“在正确的饮食量适当的食物。
”该工作涉及的营养科学家在人体中发现，每一个我们需要一笔发生的事情，当我们收到过多或过少，对粮食和死亡，我们应该吃什么食物和数额会有多大。

Lesson11）It is the chain of activities that brings food from “farm gate to plate”.这是一条使食品“从农场到餐盘”的供应链。
2）For example，fifty-six companies are involved in making one can of chicken noodle soup.例如，一种鸡肉面汤罐头的制造会牵扯到56家公司。
3）Here food was sold to grocers for sale in their local shops for purchase by local consumers.农民在农村市场将食品出售给零售商，零售商再通过商店将食品卖给当地消费者。
4）Nevertheless，less than ten percent of consumer spending on food goes to farmers , with larger percentages going to advertising , transportation ,and intermediate corporations.尽管如此，消费者花费在食品方面的开销只有不到10%到了农民手中，而食品方面的花销大部分到了广告、运输和中间公司手中。
5）Wholesale markets for fresh food products have tended to decline in importance in OECE countries as well as in Latin America and some Asian countries as a result of the growth of supermarkets , which procure directly from farmers or through preferred suppliers , rather than going through markets.超市直接从农民或选择性供应商（而非通过市场）采购食品方式的发展，已经是经合组织国家、拉丁美洲和一些亚洲国家的新鲜产品批发市场的重要性有所降低。

Eat soy in moderation. Soybeans , tofu , and other soy-based foods are an excellent alternative to red meat. But don’t go overboard. Two to four servings a week is a good target.2. It is a common belief that the more fat you eat, the more body fat you put on,and the more weight you gain. This belief has been bolstered by much of the nutrition advice given to people over the past decade , which has focused on lowering total fat intake while increasing carbohydrate intake.3. Easily digested carbohydrates from white bread , white rice , pastries ,sugared sodas , and other highly processed foods may , indeed , contribute to weight gain and interfere with weight loss.4.A new system , called the glycemic index, aims to classify carbohydrates based on how quickly and how high they boost blood sugar compared to pure glucose. Foods with a high glycemic index , like white bread, cause rapid rise blood sugar.5. Dividing carbohydrates into simple and complex makes sense on a chemical level. But it doesn ’ t do much to explain what hap pens to different kinds of carbohydrates inside the body.6. This is a tall order for knowledge. Because processing affects both nutritional and esthetic values of food, knowledge of the changes that carbohydrates undergo during milling, cooking, dehydration, freezing, and storage is especially important.7. The “balance” of certain minerals with others is very important to health as well. For example, the balance of calcium to magnesium is important as these two forms the electrical battery that keeps the heart beating.8. Assessing mineral status is equal to determining how much of a mineral in our diet is too little, too much or just the right amount. Picture yourself as a medical doctorwho must render a decision for a person suspected of having a mineral deficiency. 9. Most balance studies are short-term and therefore have important limitations.To detect how the body adapts to different calcium intakes over a long period of time, and to get the big picture of overall bone strength, requires studies of longer duration.10. Many people may think, however fiber probably has little effect on colon cancer risk. But just because fiber plays little role in preventing colon cancer doesn’t mean you should abandon a high-fiber diet.11. The fiber in wheat bran and oat bran seems to be more effective than similar amounts of fiber from fruit and vegetables. Experts recommend increasing fiber intake gradually rather than suddenly.12. This keeps blood sugar and insulin levels from rising, then falling, too quickly. Better control of blood sugar and insulin can keep hunger and may prevent the development of type 2 diabetes.13. Dairy products have traditionally been Americans’ main source of calcium. But there are other healthy ways to get calcium than from milk and cheese , which can contain a lot of saturated fat.14. People with diabete, though, should probably limit themselves to no more than two or three eggs a week, as study found that for such individual, an egg a day might increase the risk for heart disease.15. In areas most of the straw is worked back into the soil. The grain harvested from cereals provides about three-quarters of our food energy. About half of our cereals are used as miscellaneous grains so we consume them indirectly as meat , eggs and milk.16. Malt is used in brewing and distillation, in which maltose is fermented by yeast to produce alcohol. Low protein barley is used to make beer and high protein barley is used to feed pigs and cattle.17. By modern electronics technology , grain condition monitoring system can real time detect grain condition during grain storage , analyze and forecast the data , put forward treatment suggestion and control measures on exceptional grain condition. 18.The ratio of the length and the width is used internationally to describe the shape and class of the variety. The other important aspect of length and width is uniformityall the grains in one ample must look the same.19. Innovating soy and cereal dishes is an important skill for vegetarians, who need to make sure they have a balanced source of protein in their diet because of the lack of meat.20. During the cooking process, the starch granules in the grain expand and amylose leaches from them. As the cooked rice cools, the leached amylose chains line up, lock together and form a gel参考答案：1.适度吃大豆。

这些天然存在的分子可以通过采用非极性有机溶剂萃取的方法，在细胞和组织中分离得到。
2. Saturated fats have a uniform shape that allows them to pack together in a crystal lattice. Unsaturated fats have double bonds that introduce kinks into the hydrocarbon chain making crystal formation more difficult.饱和脂肪有一个均一一致的形状，这使得他它们能够在晶格中聚合起来。
不饱和脂肪有双键能使烃链发生扭曲，从而使晶体的形成更加困难。
3. The most abundant lipid in olive oil is glyceryl trioleate, a trimester formed from glycerol and oleic acid, a mono-unsaturated fatty acid with a cis double bond in the middle of the Cchain.18橄榄油里最丰富的脂质是三油酸甘油酯，是甘油和油酸，与一个单不饱和脂肪酸加上一个顺式双键在C18链的中间形成的一种三聚体。
4. Waxes are mixtures of esters of long chain carboxylic acids and long chain alcohols. The carboxylic acids usually have an even number of carbon atoms, ranging from 16 to 36, and the long chain alcohols also have an even number of carbon atoms, ranging from 24 to 36.蜡是一种由长链羧酸和长链醇通过脂键组成的酯的混合物。
长链羧酸通常由偶数个（16~36个）C原子组成，而长链醇也是由偶数个（24~36个）C原子组成。
Lesson105. This means that any catalyst that catalyze a reaction in one (e.g.,esterification) also catalyze the reverse(e.g., ester hydrolysis) reaction. To say these things another way, catalysts do not change the energy balance between reactants and products; catalysts do lower the energy barrier between reactants and products.这意味着任何一个催化剂既可以催化一个反应朝一个方向进行，也可以使其朝逆方向进行。
换句话说，催化剂不会改变反应物与产品之间的能量平衡，只是降低反应物与产品之间的能量差值。
6.Sulfuric acid as a source of H+ will catalyze the formation of any ester from the appropriate alcohol and carboxylic acid, but many enzymes are so specialized that they will catalyze a reaction of one molecule, but will leave untouched a very similar molecule.硫酸作为一个H+离子来源，能催化任何由合适的羧酸和醇构成酯的反应，而许多酶的特性很高，它们可以催化一种分子反应，但不会触及另一类很相似的分子的反应。
7. This broader specificity is useful in the case of an enzyme like papain which is important in protein digestion. It can catalyze the hydrolysis of peptide (amide) bonds in a variety of proteins, which means that the body does not need to maintain a stock of more specific enzymes to tackle specific proteins.这个广泛的特异性在酶中很有用，例如木瓜蛋白酶，它在蛋白质消化中具有重要意义。
木瓜蛋白酶可以在各种蛋白质中催化肽键的水解，从而可使人体不需要更高特异性酶来专门水解特殊的蛋白质。
8. Thus we can describe them in terms of their primary, secondary, tertiary, and in many cases, quaternary structure. They are long chains of amino acid units held together by peptide bonds, looped and folded into secondary and tertiary (and often quaternary) structures by disulfide bonds, hydrophobic interactions, and salt bridges.这样我们能从蛋白质一级，二级，三级和四级结构方面来描述酶：它们是由氨基酸通过肽键结合的单位所组成，以缠绕折叠的方式，由二硫键，疏水键，盐桥而构成二级和三级结构的许多长链。
9. In such instances, the enzyme without the cofactor is called an apoenzyme, and the apoenzyme-cofactor complexis called a holoenzyme. We will see that the protein chain of an apoenzyme can have functional groups on its side chains (R groups) which are important to its catalytic function, but other important functional groups are introduced by way of cofactors.有些时候，不含辅基的酶叫脱辅基蛋白酶，辅基和脱辅基蛋白酶的复合物叫全酶。
我们将发现由脱辅基蛋白酶组成的蛋白质链的侧链上，具有对它的催化功能起重要作用的功能基团，但其他重要的功能基团则是由催化剂的辅基提供。
10. The fit can come about either because the molecule fits easily into the enzyme's active site (lock-and-key model) or because the enzyme's structure adjusts to the substrate's entry (induced fit model).匹配进入酶的活性部位，要么因为这个分子容易进入酶的活性部位，要么因为酶的结构进行调整。
Lesson 1111. These provide the energy and building materials for the countless substances that are essential to the growth and survival of living things. The manner in which nutrients become integral parts of the body and contribute to its function is dependent on the physiologic biochemical processes that govern their actions.这些营养素为无数的生物生长和生存所必需的物质提供了能量和构建物质。
在这种方式中，营养素组成机体的有机部分，并依据控制他们行为的生理和生化过程，发挥他们的功能。
12. As constituents of food we eat they not only provide energy but also provide a basis for tastes, color, texture, keeping qualities, and overall acceptability of that food, not nutrients, and therefore should consider the total role of nutritional compounds in food.作为我们所吃食物的组分，它们不仅提供了能量，而且提供了该食物的味觉、颜色、质地、质量保持和总的接受程度。
不能遗忘的是我们吃的食物不是营养素，因此我们应当考虑到食物中营养化合物总的作用。
13. They are called essential nutrients because we cannot get along without them .We need them for energy for building and maintaining body tissue, and for regulating body process—the three essential functions of food in the body.因为我们的生存离不开它们，所以被认为是必须的营养素。
