Problems solved by technology

However, due to various factors, most pet foods can only provide pets with the basic nutrients necessary for life activities, and there is no guarantee that pets will like them, because it is difficult to change pets' eating behavior
Even if the new food provided to the pet is nutritionally balanced and meets the needs of the food, once the palatability is poor, it is difficult to increase its feed intake

Embodiment 1

[0040] A compound enzymatic hydrolyzate and its preparation:

[0041] 1) Preparation of protein hydrolyzate

[0042] Conditioning: Take meat, meat powder and other protein raw materials, grind them, pour them into the protein reaction kettle, heat up to 85°C for conditioning, and last for 15 minutes. This step can stretch the protein macromolecular structure and allow proteases to better contact the protein Structural reaction points, so that the protein hydrolysis reaction can be carried out more comprehensively;

[0043] First-level enzymatic hydrolysis: add pepsin to the reaction kettle, react at 50°C for 30 minutes, and the pH is 3;

[0044] Secondary enzymatic hydrolysis: The above enzymatic hydrolyzate was subjected to 300W ultrasonication for 2 minutes, and the enzymatic hydrolysis condition was 60°C for 15 minutes, and then the flavor enzyme was added to the reactor to continue the enzymatic hydrolysis reaction.

[0045] 2) Preparation of starch hydrolyzate

Embodiment 2

[0053] A compound enzymatic hydrolyzate and its preparation:

[0054] 1) Preparation of protein hydrolyzate

[0055]Conditioning: Take meat, meat powder and other protein raw materials, grind them, pour them into the protein reaction kettle, heat up to 80°C for conditioning, and last for 30 minutes. This step can make the protein macromolecular structure stretch out, so that the protease can better contact the protein Structural reaction points, so that the protein hydrolysis reaction can be carried out more comprehensively;

[0056] First-level enzymatic hydrolysis: add trypsin to the reaction kettle, react at 53°C for 18 minutes, and the pH is 2;

[0057] Secondary enzymatic hydrolysis: The above enzymatic hydrolyzate was subjected to 250W ultrasound for 2 minutes, and the enzymatic hydrolysis condition was 58°C for 16 minutes, and then papain was added to the reactor to continue the enzymatic hydrolysis reaction.

[0058] 2) Preparation of starch hydrolyzate

Embodiment 3

[0066] A compound enzymatic hydrolyzate and its preparation:

[0067] 1) Preparation of protein hydrolyzate

[0068] Conditioning: Take meat, meat powder and other protein raw materials, grind them, pour them into the protein reaction kettle, heat up to 80°C for conditioning, and last for 30 minutes. This step can make the protein macromolecular structure stretch out, so that the protease can better contact the protein Structural reaction points, so that the protein hydrolysis reaction can be carried out more comprehensively;

[0069] First-level enzymatic hydrolysis: Add pepsin and trypsin to the reaction kettle, react at 60°C for 15 minutes, and the pH is 5;

[0070] Secondary enzymatic hydrolysis: The above enzymatic hydrolyzate was subjected to 300W ultrasonication for 2 minutes, and the enzymatic hydrolysis condition was 50°C for 30 minutes, and then the compound animal proteolytic enzyme was added to the reactor to continue the enzymatic hydrolysis reaction.

Abstract

The invention belongs to the technical field of enzymatic decomposition, and particularly relates to a compound enzymatic hydrolysate for pet food and a preparation process thereof. The compound enzymatic hydrolysate is obtained by adding biological enzymes into protein, starch and fat raw materials and combining with ultrasonic reaction for comprehensive enzymatic hydrolysis, wherein the comprehensive enzymatic hydrolysis comprises first-stage enzymatic hydrolysis and second-stage enzymatic hydrolysis; the first-stage enzymatic hydrolysis is to add an enzyme preparation into the raw materials, adjust the pH value, and heat for enzymatic hydrolysis reaction; the second-stage enzymatic hydrolysis is to perform ultrasonic reaction on the enzymatic hydrolysate of the first-stage enzymatic hydrolysis, then add the enzyme preparation, and heat for enzymatic hydrolysis reaction; after the reaction is finished, enzyme deactivation is performed, and impurities are screened out to obtain the enzymatic hydrolysate; and small molecular nutrient substances mainly containing rich active peptides, amino acids, fatty acids, glycerol, glucose and maltose are prepared, and the small molecules help the body to fully absorb the substances, and are used for pet food, help the body to fully absorb the substances, reduce the intestinal digestion burden and improve the nutrient digestibility.

Description

technical field [0001] The invention belongs to the technical field of enzymatic decomposition, and in particular relates to a compound enzymatic hydrolyzate used for pet food and a preparation process thereof. Background technique [0002] With the rapid development of the domestic economy and changes in social structures such as empty-nest youth, people are paying more and more attention to pets, and the number of pet owners is also increasing, which has become one of the important driving forces for the development of the pet industry. The pet owners, mainly those born in the 1980s and 1990s, have gradually begun to pay attention to the eating habits and health problems of their pets, and their requirements for the nutrition and raw material formula of pet food are increasing day by day. [0003] Professional pet food is a food that provides nutrition for pets. Its main function is to provide pets with the nutrients they need, which can promote the growth and development ...
