Determination of crude fat content in soybean
As we all know, soy is a nutrient-rich food, it is rich in crude protein and crude fat, crude protein content of up to 40% and crude fat content of about 20%. It is an important source of edible oil. However, with the development of science and technology, people are increasingly satisfied with 20% of the crude fat in soybeans, and people are looking for ways to increase the content of crude fat in soybeans. At this point, the determination of crude fat content becomes particularly important. At present, there are many methods to determine the content of crude fat in soybeans. For example, the instrument method is crude fat analyzer. It has various models, such as SZF-06B crude fat analyzer and SZF-06A crude fat analyzer. Of course, it is more common that it is based on the chemical analysis of Soxhlet extraction (GB290621982). However, the first two of us cannot maintain the integrity of soybeans. At this time, a new method was born, namely, near-infrared spectroscopy. It is different from the first two methods. It is accurate, fast, simple and does not damage grains. The detection method.
The requirement of near-infrared detection technology for soybean varieties is to use as many samples as possible, cover a wide range of samples, and sample types, and then establish a detection model. When this requirement is met, the determination of crude fat in soybean by near-infrared detection techniques is relatively accurate, even higher than the accuracy of chemical analysis. And it has better stability and reliability. The near-infrared technique has been widely used, and will even replace chemical analysis and detection when it is necessary to preserve the quality of grain integrity, QTL s/gene mapping, introgression screening, and mutant screening.
Of course, the use of instruments to measure the total crude fat content in soybeans is also more widely used because of its speed and simplicity. SZF-06 Crude Fat Analyzer is heated by electric heating plate. It is fast, automatic recovery, automatic recovery of heating, including soaking and extraction process, shortening the working time, the appearance is more compact and beautiful.
