Comparative analysis of several common oil fat detection methods

Several commonly used oil and fat detection methods mainly include: Soxhlet extraction soaking, Soxhlet extraction, and Abbe refractometer method. The oil and fat are measured at the same time as the moisture content. The three methods are compared with the international method. Experimental It is concluded that the average value of the error range of the three measurement methods is less than 0.002%. Fat is an important chemical component of grains and oils, and the measurement of fat content in grains, oils, food quality and oil nutritional value evaluation is of great significance. For oil, the oil content will directly show the economic value of the oil; at the same time, the oil content is an important basis for determining the level of the oil level. There are more than 10 methods of measuring fat at home and abroad. Extraction is currently used to measure fat in the world and is widely used in the world. Among them, Soxhlet extraction (Soxhlet extraction) is a recognized traditional method for determining fat content. . In practice, there are some methods that can be shortened to improve the time used, but not compared with the GB5512-1985 national standard method, the control system.
