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 a high-quality enzymolysis-fermented bean pulp as well as a preparation method and application thereof. The preparation method comprises the steps of crushing peeled bean pulp, sieving by virtue of an 80-mesh sieve, carrying out primary enzymolysis by virtue of alpha-galactosidase and glucoamylase, carrying out secondary enzymolysis by virtue of papain, carrying out enzyme deactivation, inoculating a compound strain of saccharomycetes, bacillus and lactic acid bacteria, sequentially carrying out aerobic fermentation and anaerobic fermentation to obtain a finished product, and carrying out spray drying on the finished product, so as to preserve active components to the greatest extent. The prepared enzymolysis-fermented bean pulp has the special fermentation flavor, the protein content is about 55%, the acid soluble protein content is more than 50%, antinutritional factors such as antigens are fundamentally eliminated, the components are stable, and the enzymolysis-fermented bean pulp has the characteristics of strong hydrophily, high water holding ratio and strong palatability and has an obviously food calling effect on aquatic animals; and the enzymolysis-fermented bean pulp is rich in functional small peptides, probiotics and metabolite of the probiotics, beneficial to the nutrient balance of intestinal tract of bred animals and is suitable for being added into feeds of piglets, poultries, pets, aquatic products and the like, the problem of trophic diarherra of the animals is solved, and 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...
