Embodiment 1

[0018] The preparation process of the novel enzymolysis and fermentation plant protein feed of this embodiment, the preparation process comprises the following steps:

[0019] (1) Peeling the full-fat soybeans, removing impurities, and then superfinely pulverizing them into full-fat soybean powder with a particle size of 0.16 mm;

[0020] (2) Put the full-fat soybean powder obtained in step (1) into the reaction kettle, and mix with water at a ratio of 1:4. After mixing evenly, heat to 90°C for 6 minutes to sterilize, then cool down to 45°C and adjust The pH value is 3, and the enzyme preparation Aspergillus niger 3.350 acid protease 6000u / g is added for enzymolysis, and the enzymolysis time is controlled at 10 hours;

[0021] (3) Microbially ferment the enzymatically hydrolyzed soybean product in step (2), then dry at a low temperature, and dry at 40°C until the water content is lower than 25%, so as to obtain a new type of enzymatically fermented plant protein feed.

Embodiment 2

[0023] The preparation process of the novel enzymolysis and fermentation plant protein feed of this embodiment, the preparation process comprises the following steps:

[0024] (1) Peeling the full-fat soybeans, removing impurities, and then superfinely pulverizing them into full-fat soybean powder with a particle size of 0.16 mm;

[0025] (2) Put the full-fat soybean powder obtained in step (1) into the reaction kettle, and mix it with water at a ratio of 1:4. After mixing evenly, heat to 90°C for 5 minutes to sterilize, then cool down to 40°C and adjust The pH value is 3, and the enzyme preparation Aspergillus niger 3.350 acid protease 6000u / g is added for enzymolysis, and the enzymolysis time is controlled at 9 hours;

[0026](3) Microbially ferment the enzymatically hydrolyzed soybean product in step (2), then dry at a low temperature, and dry at 40°C until the water content is lower than 25%, so as to obtain a new type of enzymatically fermented plant protein feed.

Embodiment 3

[0028] The preparation process of the novel enzymolysis and fermentation plant protein feed of this embodiment, the preparation process comprises the following steps:

[0029] (1) Peeling the full-fat soybeans, removing impurities, and then superfinely pulverizing them into full-fat soybean powder with a particle size of 0.15 mm;

[0030] (2) Put the full-fat soybean powder obtained in step (1) into the reaction kettle, and mix it with water at a ratio of 1:4. After mixing evenly, heat to 90°C for 5 minutes to sterilize, then cool down to 40°C and adjust The pH value is 3, and the enzyme preparation Aspergillus niger 3.350 acid protease 6000u / g is added for enzymolysis, and the enzymolysis time is controlled at 9 hours;

[0031] (3) Microbially ferment the enzymatically hydrolyzed soybean product in step (2), then dry at a low temperature, and dry at 40°C until the water content is lower than 25%, so as to obtain a new type of enzymatically fermented plant protein feed.

Abstract

The invention relates to a preparation process of a novel enzymolysis fermented vegetable protein feed. The preparation process comprises the following steps: (1) peeling full-fat soybean, removing impurities, and then carrying out superfine grinding to grind the peeled full-fat soybean into full-fat soybean flour with a grain size of less than 1.7 mm; (2) putting the full-fat soybean flour obtained in step (1) into a reaction kettle, adding water and mixing, heating for sterilization after mixing uniformly, then cooling, and adding an enzyme preparation for enzymolysis; and (3) carrying out microbial fermentation on the enzymatically hydrolyzed soybean product in step (2), and then drying until a moisture content is less than 25% at a temperature of 40-50 DEG C to obtain the novel enzymolysis fermented vegetable protein feed. The preparation process provided by the invention has the advantages of taking the full-fat soybean as a raw material, adopting the enzymolysis and microbial fermentation two-step method for preparing small peptide, and improving the nutritional value by utilizing the combined action of an enzyme system secreted during the growth of thalli and an added enzyme system.

Description

technical field [0001] The invention belongs to the technical field of feed processing, and in particular relates to a preparation process of a novel enzymolysis and fermentation plant protein feed. Background technique [0002] With the rapid development of my country's aquaculture and feed industry, the demand for high-quality protein feed raw materials has increased greatly, but my country's protein feed resources are seriously insufficient, especially soybeans and fish meal, which are heavily dependent on imports, resulting in high feed production costs and serious constraints. The sustainable development of my country's feed industry. Therefore, in the current shortage of feed resources, improving the utilization efficiency of protein feed has become an important means to alleviate the shortage of feed resources, and related research has received more and more attention. [0003] Soybean and soybean meal are the most important feed protein sources in my country, with th...
