Problems solved by technology

At present, most of the food attractants on the market are flavoring agents or sweeteners, which have a single effect and can only form a single stimulus to the animal's sense of smell, vision or taste, and some flavoring agents or sweeteners are composed of Chemically synthesized products, easy to produce drug residues in animals, with obvious toxic and side effects
[0003] Prior art, such as the Chinese invention patent with the authorized announcement number CN 103734530 B, discloses a kind of aquatic feed attractant. The method combines multiple single attractants with bile salts that have the functions of promoting digestion, protecting the liver and benefiting the liver. , has a good food-attracting effect and digestion-promoting effect on aquatic animals, but the price of bile salt added in this food-attractant is relatively expensive, which increases the cost of breeding

Embodiment 1

[0017] A fish protein peptide food attractant product is prepared by enzymatic hydrolysis, Maillard reaction, ceramic membrane microfiltration and spray drying using minced fish meat.

[0018] A processing method of a fish protein peptide food attractant product, the specific operations are:

[0019] 1) Preparation of minced fish pulp: It is prepared by mixing minced fish with water after removing internal organs, gills, cleaning, cutting into pieces and mincing. The mass ratio of minced fish and water is 1:0.6, which is minced fish pulp The enzymolysis provides an appropriate amount of water, increases the enzymolysis speed of alkaline protease, and promotes the energy transfer and mass transfer of the enzymolysis process;

[0020] 2) Enzymolysis: Add papain, the addition amount is 1700IU per gram of minced fish pulp, pH is 8, and the temperature is 55°C, and the enzymolysis is carried out for 5 hours. After the end of the enzymolysis, the temperature is raised to 90°C and ke...

Embodiment 2

[0024] A fish protein peptide food attractant product is prepared by enzymatic hydrolysis, Maillard reaction, ceramic membrane microfiltration and spray drying using minced fish meat.

[0025] A processing method of a fish protein peptide food attractant product, the specific operations are:

[0026] 1) Preparation of minced fish pulp: it is prepared by mixing minced fish with water after removing viscera, gills, cleaning, cutting into pieces and mincing. The mass ratio of minced fish and water is 1:1, which is minced fish pulp The enzymolysis provides an appropriate amount of water, increases the enzymolysis speed of alkaline protease, and promotes the energy transfer and mass transfer of the enzymolysis process;

[0027] 2) Enzymolysis: Add papain, the addition amount is 1600IU per gram of minced fish pulp, pH is 9, and the temperature is 60°C, and the enzymolysis is carried out for 6 hours. After the end of the enzymolysis, the temperature is raised to 90°C and kept for 20 ...

Embodiment 3

[0031] A fish protein peptide food attractant product is prepared by enzymatic hydrolysis, Maillard reaction, ceramic membrane microfiltration and spray drying using minced fish meat.

[0032] A processing method of a fish protein peptide food attractant product, the specific operations are:

[0033] 1) Preparation of minced fish pulp: it is prepared by mixing minced fish with water after removing internal organs, gills, cleaning, cutting into pieces and mincing. The mass ratio of minced fish and water is 1:1.2, which is minced fish pulp The enzymolysis provides an appropriate amount of water, increases the enzymolysis speed of alkaline protease, and promotes the energy transfer and mass transfer of the enzymolysis process;

[0034] 2) Enzymolysis: add papain, the addition amount is 1300IU per gram of minced fish pulp, the pH is 8, and the temperature is 58°C, and the enzymolysis is carried out for 4 hours. After the enzymolysis is completed, the temperature is raised to 90°C ...

Abstract

The invention discloses a protein peptide phagostimulant product for fish. The phagostimulant product is prepared from minced fish through enzymolysis, a Maillard reaction, ceramic membrane microfiltration and spray drying. The phagostimulant product has the benefits as follows: the prepared phagostimulant has strong and pure fishy smell, keeps lasting fragrance, can cover peculiar smell of feed and has a remarkable feed attracting effect. The appetite of the fish is stimulated, the palatability of feed is improved, the immunity of the fish is improved, the ingestion rate is increased, feed residues are reduced, water pollution is reduced, and environmental protection is facilitated. The growth speed of the fish is increased, the feed conversion rate is increased, and the economic benefits of an aquaculture farmer are increased. The technological method is simple, the product quality has good stability, the cost is low, the application effect is good, and the product has good economic benefits.

Description

technical field [0001] The invention relates to the technical field of biological product preparation, in particular to a fish protein peptide food attractant product. Background technique [0002] Food attractants have obvious and positive biological effects on animal feed, which can improve the feed attraction and palatability, improve feed conversion rate, and then comprehensively improve animal production performance, such as increasing feed intake, increasing daily weight gain, Improve meat quality, etc. On the one hand, the food attractant can cover up the bad smell in the feed through the special smell, and stimulate the animal's sensory organs, so as to achieve the purpose of promoting animal feeding and accelerating animal growth; on the other hand, the food attractant induces the animal to eat, shortening the feeding time , improve the utilization rate of feed. At present, most of the food attractants on the market are flavoring agents or sweeteners, which have a...
