Fat is an indispensable nutrient for human beings. If you blindly avoid fat elements, it will cause a series of problems such as malnutrition. Moreover, the level of fat content is also an important indicator of food quality and nutritional value. Therefore, fat determination has long been a routine analysis item for food and feed. The fat analyzer can accurately determine the fat content in food. The crude fat content in food directly affects its use. For example, soybeans with high crude fat content are mostly used for oil extraction, and the remaining soybean meal is used as feed, etc.; soybeans with low oil output are mostly used for food processing.
The standard method is used to determine the crude fat content in food. First, the constant weight receiving bottle is used, and then the sample to be tested is extracted with anhydrous ether or petroleum ether. After the extraction, the anhydrous ether or petroleum ether is recovered and evaporated to dryness, and then the constant weight receiving bottle is passed. The crude fat content of the food was calculated by weighing the receiving bottle before and after extraction. Improved method constant weight sample + filter paper tube, then soak the sample with anhydrous ether or petroleum ether, after the extraction is completed, then the sample + filter paper tube after constant weight extraction, by weighing the change in the weight of the sample + filter paper tube before and after extraction, calculate the food crude. fat content. The improved method can not only overcome the systematic errors caused by the long-term use of the receiving bottle, but also improve the accuracy of the analysis and determination results, and can also improve the analysis accuracy and reduce the cost, and is suitable for the determination of crude fat in food.
It is understandable that this traditional measurement method is also possible, but it will also bring a lot of workload. If it can be detected with a fat meter, it is simple and accurate, and it can be said to be the best way.
