Soybean meal is the most abundant and most widely used animal and vegetable oil feed product such as cottonseed meal, peanut meal, and rapeseed meal. As a kind of high protein, soybean meal is the main raw material for livestock and poultry feed, and it can also be used to make cake foods, health foods, and cosmetics and antibiotic raw materials.
1. Utilization value of soybean meal in monogastric animals and complex stomach animals About 85% of the soybean meal is used for raising poultry and pigs. The various amino acids contained in soybean meal are suitable for the nutritional requirements of poultry and pigs. Experiments have shown that without additional animal protein, only the amino acids contained in soybean meal are sufficient to balance the nutrition of poultry and pigs, thereby promoting the nutrient absorption of livestock. Poultry pods have been maximally utilized in poultry and pig rearing. Only when the cost per protein of cottonseed meal and peanut meal is much lower than that of soybean meal will it be considered for use. In fact, soybean meal has become a benchmark for comparison of other protein sources.
During the feeding of dairy cows, delicious, easy-to-digest pods increase milk yield. In the feeding of beef cattle, soybean meal is also one of the most important oil seeds. Soybean meal is also used to make pet food. Simple mixed foods of corn and soybean meal have the same value as foods made from high animal protein. In recent years, soybean meal has also been widely used in aquaculture. The various amino acids contained in soybean meal can fully meet the special needs of fish for amino acids.
Second, the four methods of identification of soybean meal
1. Sensory inspection method: This method refers to the use of human sensory organs to identify the shape of the feed, particle size, color, odor, texture and other indicators. The pure pods are irregularly fragmented, pale yellow to light brown, with uniform color and occasional agglomeration, with aroma of beans. Incorporation of zeolite powder, corn and other impurities, the color is light, the color is not the same, agglomerate, visible white powder, smell a little bean flavor, doping large amount of no beans flavor. If the sample is crushed and then compared with pods, the color difference is even more pronounced. When crushed, the fake soybean meal has a large dust, and the dust in the glass window will stick to the wall of the bottle. This phenomenon does not occur in pure soybean meal. Biting pods with teeth is sticky, and corn is brittle and has powder.
2. Inspection methods for outer packaging: Fine particles, large capacity, and low price are the common features of most of the adulterants. After incorporating these substances into the soybean meal, the packaging volume must be smaller and the weight increased.
3. Microscopic examination: Take one sample of the sample to be tested and one sample of pure soybean meal and observe them under a stereo microscope. The surface of the outer surface of the shell of the pure soybean meal is smooth and glossy, and there is an imprint of the skin when being needled. It is opaque, opaque and creamy; corn kernels are smooth and translucent, with nail-like lines and stripes. This is a distinguishing feature of corn kernels from bean kernels. In addition, the color of corn kernels is also deeper than that of soybean kernels. Orange.
4, bulk density measurement method: any material has a certain weight, if doped, weight change will occur, therefore, the determination of bulk density is to determine whether the adulterated soybean meal method. The average pure soybean weight is 594.1g/L-610.2g/L. If the measured bulk density of the sample is compared with it, if it exceeds more, it indicates that the soybean meal is adulterated.
As an important role in animal husbandry aquaculture, soybean meal plays an indispensable ingredient in the feed industry. Therefore, to improve the authenticity identification of soybean meal, it is possible for the feed industry and farmers to avoid unnecessary losses and save the cost of cultivation. .
Organic Echinacea Purpurea Extract
Echinacea is a genus or group of herbaceous flowering plants in the daisy family. The Echinacea genus has nine species, which are commonly called purple coneflowers. They are found only in eastern and central North America, where they are found growing in moist to dry prairies and open wooded areas. They have large, showy heads of composite flowers, blooming from early to late summer. These flowering plants and their parts have different uses. Some species are cultivated in gardens for their showy flowers. Echinacea purpurea is used in folk medicine. Two of the species, E. tennesseensis, and E. laevigata, are listed in the United States as endangered species.
