In addition to strict management, scientific formula, innovative technology, raw materials are the basis for the manufacture of fine feed, soybean meal as one of the richest nutritional value, amino acid content of one of the most ideal plant protein, is one of the most important plant proteins in the feed formula diet, however, the raw materials seem to be the same, the quality is very different! Therefore, screening high-quality peeled soybean meal is an important basis for intelligent manufacturing of high-quality feed. In the past, lean quality control in the training of national cooperative customers often said that the quality control point of soybean meal is the quality control point of soybean production area, soybean variety, soybean process, urease activity, soybean skin content, impurity content, crude fiber content, etc. The quality control points of soybean new aging are less training, in fact, soybean meal and corn are the same: the use of aged corn will cause poor palatability of suckling pigs, the amount of food intake will even produce yellow meat, the use of aged soybean processing soybean meal, not only the feed made is ugly without gloss sensory difference, It will also affect the palatability and feeding volume of suckling pigs. Recently, the author found that there are individual soybean meal enterprises using chen bean processing soybean meal or puffed soybeans, especially reminding feed enterprises and breeding enterprises to pay attention to and fine identification of soybean meal quality, only to achieve raw materials, feed can be fine. Soybean meal processed by Chen Bean has the following characteristics:
First, the color.
The soybean meal processed by Chen soybean is gray and dark, dark yellow-brown, has no luster, no light and vitality of healthy soybeans, and the color is pathologically ugly;
Second, the smell.
Soybean meal processed by aged soybeans does not have the fresh bean flavor of soybean meal, has no aroma, and has the characteristic aging odor of aged soybeans or the aroma is weak or odorless;
Third, the taste.
The taste of soybean meal processed by aged soybeans is not as strong as that of fresh soybean processed soybean meal, and it has a sick feeling of difficulty swallowing after careful chewing, and the taste is poor;
Fourth, texture.
Soybean meal processed from aged soybeans is sickly irregular, and the fluidity of soybean meal processed without fresh soybeans is good.
