Problems solved by technology

Unstable product quality, poor palatability, incomplete treatment of anti-nutritional factors, or substandard small peptide content are common problems, which cannot effectively replace fish meal and truly meet the requirements of young animals for palatability, anti-diarrhea, and high digestibility
Similar products are more dependent on imports, such as: Danish Hamlet, etc., but due to problems such as high prices, unstable resource supply, and long transportation cycles, imported products are used in a small proportion in actual production

Abstract

The invention relates to fermented soybean meal and a preparation method thereof. The preparation method of the fermented soybean meal comprises the following steps: crushing peeled soybean meal and performing sieving with an 80-mesh sieve, carrying out first-step enzymolysis by using alpha-galactosidase and glucoamylase, then carrying out second-step enzymolysis by using papain, carrying out enzyme deactivation, inoculating a composite strain of saccharomycetes, bacillus and lactic acid bacteria, carrying out aerobic fermentation, then carrying out anaerobic fermentation, and carrying out spray drying on the finished product to retain active ingredients to the maximum extent. The prepared enzymatically hydrolyzed and fermented soybean meal has specific fragrance of fermentation, the protein content is about 55%, and the acid-soluble protein content is greater than 50%. Antinutritional factors such as antigens are basically removed, and the components are stable. The enzymatically hydrolyzed and fermented soybean meal has the characteristics of strong hydrophilicity, high water retention rate, high palatability, obvious phagostimulant to aquatic animals and the like. The fermentedsoybean meal is rich in functional small peptides, probiotics and metabolites of probiotics, is beneficial to intestinal nutrition balance of cultured animals, can be used to solve the problem of nutritional diarrhea of animals, and is suitable for feed for piglets, poultry, pets, aquatic products and the like, wherein the suggested use ratio is 2-5%.

Description

technical field [0001] The invention relates to a high-quality enzymolysis fermented soybean meal, a preparation method and application thereof. Background technique [0002] Soybean meal is a by-product of soybean oil extraction, because it is rich in protein (content: 43-48%), relatively balanced amino acids, various mineral nutrients, and lysine ( content: 2.5-2.8%), is widely used in the feed industry. However, during the oil extraction process, the obtained soybean meal is often subjected to high temperature treatment, resulting in serious protein denaturation and poor solubility, which is not conducive to animal digestion and absorption. At the same time, soybean meal also contains many anti-nutritional factors, such as phytic acid, oligosaccharides and glycinin, and other heat-stable anti-nutritional factors. Therefore, if untreated soybean meal is directly fed by animals, it is easy to cause diarrhea And intestinal allergies and other problems, especially unfavorab...
