纯牛奶保质期45天的好还是6个月的好 纯奶过期之后还能喝吗

纯牛奶保质期45天的好还是6个月的好 纯奶过期之后还能喝吗

纯牛奶保质期45天的好还是6个月的好纯奶过期之后还能喝吗纯奶生活中常见的一种饮品,营养价值比较高,适量食用对人体的健康具有一定好处,那么纯牛奶保质期45天的好还是6个月的好?纯牛奶过去之后还能喝吗?一、纯牛奶保质期45天的好还是6个月的好不能片面的进行判断,需要结合实际情况而定,各自都有相关优势。

营养角度:保质期45天的好纯牛奶的保质期和其灭菌方法有关,而灭菌的方法直接影响到纯牛奶的营养成分含量,保质期越短的纯牛奶,其灭菌后营养成分损失少,从饮用的营养角度来看,会比保质期6个月的纯牛奶好一些。

保存方便程度:保质期6个月的好纯牛奶保质期45天和保质期6个月,最大的区别就是两者的保存时间不一样,保质期45天的纯牛奶多为鲜牛奶,运输和销售时需要冷藏保存,否则容易滋生细菌导致纯牛奶变质,而保质期6个月的牛奶由于杀菌较为彻底,在常温下避光保存即可,比保质期45天的纯牛奶更加方便。

销售价格:保质期6个月更便宜保质期比较短的纯牛奶对奶源的产地、生产工艺、运输条件、存放条件都有着较高要求,通常价格偏贵,几乎是保质期长的纯牛奶的两倍价格,因此从价格上说,保质期6个月的纯牛奶比较划算。

二、纯牛奶过期之后还能喝吗不建议再喝。

纯牛奶是具有一定保质期的,也就是说在保质期时间之内饮用纯牛奶是没有什么危害的,但要是在保质期之外饮用纯牛奶,这时候的纯牛奶很有可能已经滋生了大量的细菌以及微生物,饮用之后容易加重人体胃肠道负担,从而可能会出现腹痛、腹泻以及便溏等不适症状的发生,对人体的健康造成威胁,所以过期的纯牛奶是不建议饮用的。

三、纯牛奶什么喝最好主要有三个时间段喝纯牛奶最好,具体如下:早上纯牛奶中含有丰富的蛋白质、维生素以及钙质,早上适量饮用可以为人体提高能量,使人体可以充满精力的迎接新一天的工作或者学习。

下午人体经过了一上午的工作、学习之后,身体会比较疲倦,这时候适量饮用一些纯牛奶,可以帮助人体迅速吸收能量,缓解困倦现象。

晚上纯牛奶中含有一定量的L色氨酸以及微量咖啡因,这些物质具有较好的镇静作用,可以帮助人们快速入眠,其次还可以帮助补充人体的钙质,有利于人体健康。

臺大歷史學報第45期BIBLID1012-8514(2010)45p.327-340 2010年6月,頁327-3402009.11.4收稿,2010.3.15通過刊登§書評§蒙元的政治,文化的蒙元──評介宮紀子,《モンゴル時代の出版文化》名古屋:名古屋大学出版会,2006,732頁。

吳雅婷*蒙古、蒙元的歷史,由於牽連地區廣闊、語言複雜,無論在中國史、東亞史乃至於世界史的領域中,一直被視為研究的難關。

在與中國史較為相關的研究範疇中,學者們的興趣一開始多在蒙古部族、大元帝國的制度,而後逐漸將眼光移至蒙元治下的中國江南,試圖了解當時的社會、經濟狀況。

這些問題一方面由於史料較易入手,另一方面亦呼應近二十年來中國近世史研究對於士人問題的關懷──或者也可以理解為「中央與地方」或統治問題的延伸,江南士人的群體活動遂獲得相當的重視。

1無論通史專著或單篇論文,或涉及文人、社會的議題,既有的研究都罕見述及蒙元的出版情形,更遑論將「出版」、「書籍」、「閱讀」作為議論核心。

由此,本書已具有值得注目的價值。

* 國立臺灣大學歷史學系博士後研究10617臺北市大安區羅斯福路4段1號;E-mail: d8*******@.tw.1這一方面以蕭啟慶教授的「多族文士圈」為最具代表性的經典論述。

參見蕭啟慶,《元代史新探》(臺北:新文豐出版公司,1983),以及《蒙元史新研》(臺北:允晨文化,1994)。

蕭教授流風所及,影響臺灣許多踏入元史領域後生學者的研究取向。

1999年,新竹清華大學舉辦「海峽兩岸蒙元史學術研討會」,會議論文出版為《蒙元的歷史與文化──蒙元史學術研討會論文集》(臺北:臺灣學生書局,2001),由蕭啟慶主編,許守泯協編。

該論文集中,士人問題頗具份量,其餘的關注焦點則在制度、政局、新史料、民族問題等方面,宗教只有一篇。

至於日本方面的研究可參見杉山正明,〈第三章 モンゴル時代史の研究──過去.現在.将来〉,收入氏著,《世界史を変貌させたモンゴル─時代史のデッサン》(東京:角川学芸,2007再版),頁147-227。

《育才报·语⽂周刊》⾼⼀第45期发《逝者如斯夫 ——梁实秋谈时间》本期主题逝者如斯夫——梁实秋谈时间江西省⼤余中学程秀全主题描述:时间是个永恒的话题。

孔夫⼦早就有“逝者如斯夫,不舍昼夜”的慨叹,⽩居易说:“五⼗已后衰,⼆⼗以前痴,昼夜⼜分半,其间⼏何时?”⼈⼀辈⼦,真正能掌握并且合理运⽤的时间有多少呢?⾯对匆匆不易把握的时间,我们应该如何对待?今天,我们就⼀起来聆听散⽂⼤家梁实秋先⽣对时间的感悟与把握吧。

名家档案1:精品阅读1写作⼩链接技法⼩课堂议论⽂技法之“引⽤论证”精彩⽚段:陆放翁有句云:“待饭未来还读书。

”我知道有⼈就经常利⽤这“待饭未来”的时间读了不少的⼤书。

古⼈所谓“三上之功”,枕上、马上、厕上,虽不⾜为训,其⽤意是在劝⼈不要浪费光阴。

(选⾃梁实秋《养成好习惯》)技法讲解:作者先引⽤陆游的诗句,然后对这句诗进⾏分析,说明等饭来的那会⼉功夫也可以⽤来读书;接着引⽤古⼈的“三上之功”,把“待饭未来”这⼀点延伸开来,讲到“枕上、马上、厕上”,并由此说明⽤于读书的时间多得很,⽽要的是“不要浪费光阴”。

引⽤论证,既能⽤名⼈名⾔更好证明你的观点,也能让议论⽂内容充实丰富,还能表现出你的⽂采。

名家档案:精品阅读1第⼀步——整体感知时间即⽣命梁实秋最令⼈怵⽬惊⼼的⼀件事,是看着钟表上的秒针⼀下⼀下的移动,每移动⼀下就是表⽰我们的寿命已经缩短了⼀部分。

再看看墙上挂着的可以⼀张张撕下的⽇历,每天撕下⼀张就是表⽰我们的寿命⼜缩短了⼀天。

因为时间即⽣命。

没有⼈不爱惜他的⽣命,但很少⼈珍视他的时间。

如果想在有⽣之年做⼀点什么事,学⼀点什么学问,充实⾃⼰,帮助别⼈,使⽣命成为有意义,不虚此⽣,那么就不可浪费光阴。

这道理⼈⼈都懂,可是很少⼈真能积极不懈的善于利⽤他的时间。

我⾃⼰就是浪费了很多时间的⼀个⼈。

我不打⿇将,我不经常的听戏看电影,⼏年中难得⼀次,我不长时间看电视,通常只看半个⼩时,我也不串门⼦闲聊天。

《教育周报·小学语文》四年级下册【人教部编版)第45期 期末

《教育周报·小学语文》四年级下册【人教部编版)第45期期末冬天刚刚离去,春天来到人间。

春天来了,小草从土地里悄悄地冒出来。

春天柔软的风吹绿了小草,吹鼓了小花的花苞,绽出洁白的花蕊。

门前小杨树长出了嫩绿的叶子,密密麻麻布满枝条。

走在小路上,我看见一棵翠绿的小草沾着晶莹的露珠在一起,鲜亮无比。

在一家院子里的墙角,生长着一颗绿色而不屈不挠的小桑树,它的根须乌在细小的石缝里,Toothed地舒展着苏醒的枝梢,我敬佩它勇敢而不屈服困难环境的精神。

我走到田野的一边,大片大片的蔬菜和庄稼,远远望去,成了绿色的地毯,装点着大地。

我陶醉了,倾心于绿色的希望与鸟儿的歌声,我想,我是一只小鸟儿,我会在天空中自由的飞翔,我多么希望有一双翅膀呀!在大自然中聆听歌声,言着花草盛开出来的清爽的气味。

非常感谢春天,春天属每个无忧无虑的孩子和细心体会生活的人。

美丽的春天来了!春天的风景就是四季中最美丽的风景!蓝蓝的天空中飘着朵朵白云,红红的太阳摆在天空,温暖的阳光吹入大地。

高高的山,层层叠叠,连绵起伏,一座蓝,一座青,一座淡,一座浓,像是一幅迷人的风景画。

小草幼苗了,桃花开了,柳树也蓝了,马尾长长的辫子在春风中左右摇摆。

小动物们也出来了。

小鸟们叽叽喳喳地叫着,有的在快乐地找吃的,有的在忙着建鸟窝------鱼儿们在湖水里高兴地玩耍,青蛙在湖面上游玩。

蝴蝶在草地上翩翩起舞,蜜蜂在五彩缤纷的花丛中忙碌地采蜜。

春天真是太美了!暖暖的春风抚摸着我的脸庞,细细的春雨沐浴着我,燕子叽叽喳喳地叫着,我才感觉到春天已经悄悄地来到了。

从公园里,已经能够找出率先被春姑娘施法的小草、小花,小草将头寻发掘出外,好象在说道:“春天去了!”,大迎春花听到了,也送出了淡黄色的小花,说道:“春天去了!,春天去了!”,小鸟听到了,说柳树,柳树遮住了绿绿的小结,好象盘起了早春的辫子。

就这样,像是接力赛似的,春天爆出了草地,爆出了公园。

春天又埃尔塞了校园,传至了路边……经过春雨的沐浴,更多小草钻出土地,更多小花争相开放,更多大树梳成了春天的辫子……春雨细细地,沙沙地,有魔力的'……春光充斥着春风,充斥着春雨一起送来了春天的魔法,春天的颜色,春天的形态……,使我们用欢欣的心情迎春天吧,享用春天剥夺的花香。

牛奶保质期45天和6个月区别

牛奶保质期45天和6个月区别牛奶保质期45天和6个月区别现在很多人都知道牛奶是不能久放的,但是大部分人还不知道究竟怎样才算“过期”。

什么是“过期”?通俗一点讲,“过期”就是食品包装上的保质期。

牛奶的保质期最长也就6个月,超过了这个期限,就属于“变质”。

为什么我们要如此注重产品的生产日期和有效期呢?这主要跟两方面的原因有关:一方面,消费者可以根据产品的生产日期和有效期来判断所购买的产品是否在保质期内;另一方面,生产企业必须根据产品的生产日期和有效期来安排生产,根据产品的生产日期和有效期来决定产品的销售时间和市场占有率。

因为很多厂家都会用各种手段提前将产品卖出去,把产品的生产日期和有效期搞错或者模糊了,就会给自己造成巨大的损失。

“过期”的牛奶真的没法喝了吗?“过期”的牛奶中的蛋白质和维生素等营养物质并没有因为时间的推移而减少,只不过酸度增加了,口感有些变化而已,并没有变质。

因此,牛奶过了保质期也是可以饮用的。

不过,在煮牛奶之前要注意看牛奶包装上的保质期,尽量选择离生产日期越近越好的牛奶。

如果是袋装牛奶,每次取出一小袋,剩余的放入冰箱冷冻室里储存即可。

但对于那些不是“即饮型”的牛奶,如常温奶、巴氏杀菌奶、高钙奶等,在饮用之前要注意看生产日期和保质期,最好选择日期最新鲜的牛奶。

另外,应该学会正确存放牛奶,避免因存放不当造成牛奶变质。

如果把牛奶存放在阴暗潮湿的地方,牛奶表层容易出现细菌,导致牛奶发霉。

如果把牛奶存放在阳光直射的地方,牛奶里的脂肪容易被氧化,导致牛奶变质。

如果把牛奶存放在过热或过冷的环境中,牛奶里的乳糖会发酵,导致牛奶酸败。

最后,如果不能饮用了,那么就把牛奶倒掉吧。

千万不要喝已经变质的牛奶,这样会引起腹泻、肠胃炎、食物中毒等症状。

为什么市场上的牛奶有很多种包装?据业内人士介绍,牛奶的包装从2克到5克不等,从简单的无菌袋包装到更复杂的利乐枕包装。

为什么不同厂家生产的牛奶,其包装也不一样呢?其实,这主要是由于不同的厂家生产设备和工艺不同,使得包装不统一。

In an emergency it is of more than average importance. With electronic systems out of service, you should keep a close check on speed, direction and distance made good; carefully evaluate the effects of wind and current; then determine your position by dead reckoning. Long voyages with accurate landfalls have been successfully completed by this method alone. This is not meant to minimize the importance of other methods of determining position. However, dead reckoning positions may be more accurate than those determined by other methods. If the means of determining direction and distance are accurate, it may be best to adjust the dead reckoning only after a confirmed fix.93. Landfall means ______.A. a dead reckoning positionB. a confirmed fixC. electronic systems out of serviceD. that land is first sighted from a long voyage94. The dead reckoning ______.A. will minimize the importance of other methods of determining positionB. is likely to become more accurate in an emergencyC. will cause electronic systems to failD. is easier than other Types of navigation95. The dead reckoning position is ______.A. less accurate than a confirmed fix in most casesB. more accurate than those determined by electronic systemsC. always very accurateD. of more than average importance to determine the speed, direction and distance made good96 In the author‟s opinion, dead reckoning position has all of the following characters except ______.A. it should only be adjusted after a confirmed fixB. it is very important in emergencyC. it is more accurate than those determined by other methodsD. in a long voyage, only dead reckoning will successfully make you arrive at your destination。
