testo 食用油品质检测仪操作说明testo 食用油品质检测仪操作说明一、仪器的标定/校准操作步骤为确保仪器的高测量精度,首先要对仪器做定期的标定/校准(建议每月1次)。

准备标定/校准:1、在标定/校准前先清洗探头注:应使用弱性的清洁剂,标准的清水或者肥皂水清洗;应用软纸巾轻轻的清洗探头,或者在清水中冲洗;应用软纸巾小心擦干探头。

2、水浴加热标定油瓶注:在室温中进行标定(约20~25℃);在约50℃下进行校准。

标定/校准:1、打开仪器,在屏幕自测同时按下Hold键和下键约3s;2、在配置模式中一直按Hold键到屏幕显示CAL;3、使用上键或下键打开标定/校准功能,按Hold键确认;4、将探头侵入标定油中,注意浸入深度要适中,且探头要与容器壁及容器底部离开1cm以上;5、按下Hold键开始标定/校准,此过程中要在油中搅动探头,以便获得更快更准确的读数;6、测量结束后,对比显示屏中的值和标定油瓶标签上的参考值。

若差值>1%,需要进行校准:使用上键或下键来设置TPM值,使之与标定油瓶标签上的值相同;若差值<1%,则不需要进行校准;7、继续按Hold键,标定/校准结束,回到测量模式。

二、样品TPM值检测操作步骤标定/校准后,就可用来进行对样品的检测了。

执行测量:1、打开仪器,仪器进行自测后,进入测量模式,此时屏幕显示000,且LED 灯亮成绿色;2、将探头浸入油中,注意浸入深度(油温的允许范围为40~200℃);3、当温度不变时,测量就结束了,若自动保持功能激活时,仪器会自动结束测量,并有警报声发出,记录TPM值及温度值,再次按下Hold键,仪器回到测量模式;4、长按Hold键关闭仪器,清洗探头并小心擦干。

注意:1、在测量中应关掉感应电煎锅,因为电磁场会影响测量结果;2、应把容器中的油炸物移出并等待5分钟后再进行测量;3、每一次测量前或者下一次连续测量前清洗探头;4、尽量避免让探头碰触金属物,如:煎炸篮,锅壁,因为这些东西都可能影响测量结果,与金属物的最小距离应为每一边至少1cm;5、煎炸油中油温不均匀可能导致测量误差,应在测量时用仪器搅动煎炸油,使之尽量温度均匀;6、煎炸油中不能含水,含水可能导致结果的不准确,若怀疑煎炸油中含水导致测量结果的不可信,可等待5分钟后重复测量,如果度数变低说明油中含水,此时可再等5分钟再次重复测量,直到度数稳定,说明油中已无水。

食用油极性物质及电导率测定

食用油极性物质及电导率测定
油脂属于非导电物质电导率极低,但研究发现泔水油的电导率极高,这可能是因为泔水油在烹调过程中添加了易电离物,如食盐、味精等调味剂。另外,回收过程中出现的金属离子微生物和杂质等污染,也会使电导率增加。电导率法操作简单不需要特别高档的仪器和设备因而可作为快速检测的初筛手段。
实验步骤:
1、食用油极性物质测定(testo)
实验名称
食用油极性物质及电导率测定
指导教师
李天骄
授课对象
12食品
实验地点
食品分析实验室
实验目的:了解食用油极性物质和电导率的测定方法。
实验原理:煎炸油中总极性物质的含量(即%TPM)可作为衡量油脂品质的一个好指标,因此,许多国家将食用油煎炸过程中总极性物质含量在24%~30%作为法定界限。我国对煎炸油脂安全性极为重视,早在1986年颁布第一部食用植物油煎炸卫生标准;1996年进行第一次修改和补充;2003年进行第二次修改,为GB7102.1-2003,其中规定极性组分含量≤27%。
在煎炸过程中,煎炸油长时间处于高温、与氧气接触导致煎炸油中的甘油三酯发生氧化反应,产生氧化产物,醛、酮、酸以及烃类,同时,煎炸食品带入体系的水在高温催化下,导致煎炸油中的甘油三酯水解,产生游离脂肪酸等。另外,多双键脂肪酸的分子容易聚合,聚合有两种形式即热聚合和氧化聚合。这些氧化、水解、聚合等反应产物,即为煎炸油中的极性物质,在煎炸过程中煎炸油的极性物质含量随煎炸时间而增加,同时煎炸油中对健康有害的成分含量增加,导致基因突变、染色体突变从而诱发癌症如乳腺癌、结肠癌等。
五问:问商家的进货渠道,必要时索要进货发票或查看当地食品卫生监督部门的抽样检查报告。
附:地沟油的感官鉴定
一看:看透明度,看色泽。颜色发暗,比较混浊,且有沉淀物,低温易凝固的可能是地沟油。检测窍门一是给冰棍上倒上一点油,油很快凝固并附着在冰棍上,则很可能是地沟油做成的。窍门二是玻璃上倒上一点油,如果油流的很慢,则可能有问题。

Basic safety instructions52. Intended use6You can use the testo 476in a variety of industrial, laborato-ry, R&D and academic environments.Most commonly, the testo 476is used to make objects which are moving at high speeds appear to be moving in slow motion. When this occurs, you can then safely and easily analyse their motion, check for proper registration, determine sources of unwanted vibration, etc.Also, you can use the testo 476to apparently “freeze” an object’s movement. Without making contact, you can accurately measure the object’s rotational speed or recipro-cation rate.Unlike other portable stroboscopes, the testo 476 (XENON-)stroboscope takes only one hand to operate. Typical applications include use with:-High speed assembly lines, conveyor systems, bottling operations, etc.-Printing presses and cloth looms-Motors, fans, pumps and turbines-Calibration and inspection equipment-Monitoring laboratory & research applications4. Overview7On/OffFlash Adjustment Knob adjusts the flash rate. Thespeed with which the flash rate changes is controlled by how quickly the knob is rotated:Quick rotation =flash rate changes in largeincrements.Slow rotation =flash rate changes in smallincrements.LCD display shows flash rate (flashes per minute =FPM).Low Bat indicator will light up when the battery needs charging.Power supply socket (incl. battery charging)The External Trigger Jack is used when employing an external sensor to control the flash rate.EXT illuminates when External Trigger Jack is plugged. Lanyard can be looped on a belt or used as a wrist strap.Front Bezel Screw is removed in order to replace the flash tube.Underside:Close-up of LCD:85.1 Mains unit SetupWhen first using the mains unit, select the appropriate plugconnector for use in the AC power outlet (several stylesprovided). Align the holes in the rear side of the plug con-nector ( ) with the pins in the receptacle in the mains unitbody ( ) and push. When properly seated, you will hear aclick and the plug connector will not move. The charger isnow ready for use.Change the Plug ConnectorTo remove the connector from the mains unit, slide theswitch on the mains unit ( ) up and the connector will popout. To insert a different plug connector follow the procedu-res described in Battery Charger Setup.5.2 Charge the batteryCharge the battery before first use or when the “LOW BAT“indicator appears on the LCD.NOTE:When the “LOW BAT” indicator is shown, the testo476hasapproximately 6 minutes of operating time remaining. Whenthe “LOW BAT” indicator flashes on and off, the battery isempty and the testo476will automatically switch off.Before first use, you must set up the battery charger. Referto 5.1 Battery Charger Setup.1Insert the barrel plug end of the mains unit into thepower supply socket on the testo476.Plug the mains unit into a mains socket.2The red light on the mains unit will illuminate continuous-ly while the battery is charging.-The instrument will recharge in about five hours.9107. Error messagesE1:Front bezel is not fastened correctly. If the E1 messa-ge appears, the instrument must be switched off.Remove the front bezel screw, reseat the reflectorand tighten the front bezel screw ( ).Underside: EXT illuminates when External Trigger Jack is plugged.10.1 Slowing down motionAs discussed, the primary use of the Pocket-Strobe is to slow down or “freeze” the apparent motion of moving objects. This allows you to analyse their run-time per-formances safely and easily.To make an object appear to move in slow motion, you need to strobe it at a rate slightly above or slightly below its actual speed (or any harmonic of its speed as discussed below). Simply use the COARSE/FINE ADJUSTMENT knob until you achieve the desired apparent movement. Helpful Hints:The speed at which the object appears to move can be determined by subtracting the flash rate from the object’s actual rate.Example:If an object is rotating at 1,000 RPM and you strobe it at a rate of 1,005 flashes per minute (FPM), the object will appear to be moving at a rate of 5 RPM.Speed=Actual Rate - Flash Rate=1,000 PRM - 1,005 PRM=5 RPM10. Application information10.2 Apparent direction of movementThe direction (clockwise vs. counterclockwise or forwardvs. backward) at which the object appears to move isdetermined by the flash rate, the object’s actual direction ofmovement and the orientation of the stroboscopic beam tothe object.Example:Assume you wish to visibly slow down the movement of afan which is rotating clockwise at 1,000 RPM.Case 1:If you stand in front of it and strobe it at a rate of1,005 flashes per minute (FPM), the object will appear tobe moving at a rate of 5 RPM in a counterclockwise direc-tion.Case 2:If you stand in front of it and strobe it at a rate of995 FPM, it will appear to move at a rate of 5 RPM in aclockwise direction.Case 3:If you stand behind it and strobe it at a rate of1,005 FPM, it will appear to move in a clockwise directionat a rate of 5 RPM.Case 4:If you stand behind it and strobe it at a rate of995 FPM, it will appear to move in a counterclockwisedirection at a rate of 5 RPM.10.3. HarmonicsIf you continuously increase the flash rate while strobing anobject, it may appear to freeze, slow down, speed up, goforward, freeze again, go backwards, form multiple images,etc. These images appear at mathematically determinedmultiples or harmonics of the object’s actual speed.Example:Assume you wish to slow the motion of the fan used in thelast example, but you want it to be brighter.Technique: Starting from 1,000 FPM, slowly increase theflash rate. At 1,500 FPM the image will appear to freezeagain. Continue to increase the rate.10. Application information The image will appear to freeze again at 3,000 FPM. At this rate, the fan appears to be very bright. You can now use the FINE ADJUSTMENT knob to vary the rate above and below 3,000 to make the fan appear to move both clok-kwise and counterclockwise.Helpful Hints:-Harmonic images appear at both whole number multi-ples as well as fractional intervals of the object’s actual rate.For example, a fan rotating at 1,000 RPM will appear to be frozen at the whole number multiples of 2,000 (2x), 3,000 (3x), 4,000 (4x) etc., as well as at thefractional rates of 500 (1/2x), 750 (3/4x) and 1,500(11/2x), etc.-Some of the harmonic images are “singular” in appea-rance while others are “multiple”. This becomes impor-tant if you want to determine the objects actual rate as discussed in chapter 10.4 Determing an object’s trueRPM.10.4 Determing an object’s true RPMThe Pocket-Strobe can be used as a digital tachometer to determine the true RPM and/or the reciprocation rate of an object. This is done by visually “freezing” the object’s movement and then reading the LCD display. As with all stroboscopes, it is important to verify that this frozen image is not a harmonic of the object’s actual rate.Helpful Hints:-Knowing the approximate rate of the object in advance gives you a useful starting point.-If the object has a uniform shape, like a multi-blade fan or motor shaft, you must give it an identifying mark(using paint or reflective tape or equivalent) in order to differentiate its orientation.- A single image always appears if the rotational speed set on the instrument matches the rotational speed of the object or if an integer divisor (1/2, 1/3, ...) of theobject speed has been set on the instrument.10. Application informationExample 1 (mark needed):This example shows why identifying marks are important.Suppose you want to determine the true RPM of this fan.The only thing you know is that its speed is less than 3,500RPM. If you slowly decrease the flash rate starting from3,500 FPM, the following “frozen” images appear:No.: 1 2 3 4ImageRate: 3,300 2,200 1,6501,320No.: 5 6 7 8ImageRate: 1100825 733.3 550FlashWhat is the actual rate of the fan? Images 1, 3, 5, 6 and 8are all “frozen,” so the rate could be taken as 3,300, 1,650,1,100, 825 and 550. Which is correct?In order to determine the fan’s actual speed, a mark isadded to one of the blades and the test is run again.No.: 1 2 3 4ImageRate: 3,300 2,200 1,6501,320No.: 5 6 7 8ImageRate: 1,100825 733.3 550Flash10. Application information Using the orientation mark, it is now clear that the images appearing at 3,300, 1,650 and 825 RPM are multiple-image harmonics. In each of these cases, three identifica-tion marks appear. On the other hand, a singular image appears at 1,100 and again at 550.The first single image with only one reflection mark appearsif 1.100 rpm has been set on the instrument, another oneat 550. Please remember, a single image always appears ifthe rotational speed set on the instrument matches the rotational speed of the object or if an integer divisor (1/2,1/3, ...) of the object speed has been set on the instru-ment. The true rotational speed therefore is 1.100 rpm. Ifthe instrument is set to 550 rpm, only every second rotor revolution will be flashed.Example 2 (no mark needed):This example illustrates how the actual speed of an objectcan be determined without the use of an orientation mark -provided that the object has a suitable shape.Assume that the speed of this cam is known only to beless than 7,000 RPM. Because it has a unique shape, itdoes not need an identifying mark. As the flash rate islowered from 7,000, the following harmonic images appear: No.: 1 2 3 4 ImageRate: 6,000 4,000 3,0001,500 FlashThe harmonic images at 6,000 and 4,000 RPM are not sin-gular, but double and quadruple. A singular image does appear at 3,000 and again at 1,500 RPM. 3.000 rpm is the actual rotational speed.11. MaintenanceDue to the high voltage contained within the testo 476, theuser should not attempt to repair the device (exception:Replacing the flash tube, see p.12).If your testo476needs repair, please contact the nearestTesto service point.Clean the external surfaces with a dry, lint free cloth only.Do not allow any liquids to enter into the instrument.13.

二、样品TPM值检测操作步骤标定/校准后,就可用来进行对样品的检测了。

执行测量:1、打开仪器,仪器进行自测后,进入测量模式,此时屏幕显示000,且LED 灯亮成绿色;2、将探头浸入油中,注意浸入深度(油温的允许范围为40~200℃);3、当温度不变时,测量就结束了,若自动保持功能激活时,仪器会自动结束测量,并有警报声发出,记录TPM值及温度值,再次按下Hold键,仪器回到测量模式;4、长按Hold键关闭仪器,清洗探头并小心擦干。

注意:1、在测量中应关掉感应电煎锅,因为电磁场会影响测量结果;2、应把容器中的油炸物移出并等待5分钟后再进行测量;3、每一次测量前或者下一次连续测量前清洗探头;4、尽量避免让探头碰触金属物,如:煎炸篮,锅壁,因为这些东西都可能影响测量结果,与金属物的最小距离应为每一边至少1cm;5、煎炸油中油温不均匀可能导致测量误差,应在测量时用仪器搅动煎炸油,使之尽量温度均匀;6、煎炸油中不能含水,含水可能导致结果的不准确,若怀疑煎炸油中含水导致测量结果的不可信,可等待5分钟后重复测量,如果度数变低说明油中含水,此时可再等5分钟再次重复测量,直到度数稳定,说明油中已无水。
