A compound enzyme preparation for enzymolysis of chicken liver and its application

Abstract

The invention discloses a composite enzyme preparation for chicken liver enzymolysis and application thereof, and belongs to the field of composite enzyme preparations. The composite enzyme preparation is prepared from the following ingredients in parts by mass: 1 to 3 parts of neutral protease, 1 to 6 parts of alkaline protease, 1 to 3 parts of lipase, 0.1 to 0.3 part of internal organ enzymes, 0.1 to 0.4 part of flavor enzymes and 3 to 5 parts of carriers. The neutral protease, the alkaline protease, the lipase, the internal organ enzymes, the flavor enzymes and the carriers are compounded into the composite enzyme preparation according to different enzyme activities, proportioning ratios and doses; the chicken liver is subjected to enzymolysis; the product protein hydrolysis degree andnitrogen recovery rate are higher; the amino acid molecular weight is small; the bitter amino acid is few; the palatability is high; very high nutrition values are realized. The enzymolysis product issubjected to settlement and freeze drying to be further prepared into chicken liver protein powder; the protein content is high; the chicken liver protein powder replaces partial fish meal to be usedfor feeding animals; the animal growth performance can be improved; the culture benefits can be improved; the culture cost is reduced.

Description

technical field [0001] The invention belongs to the field of compound enzyme preparations, in particular to a compound enzyme preparation for enzymolyzing chicken liver and its application. Background technique [0002] In recent years, my country's chicken production has steadily increased. In 2013, the total production ranked second in the world, becoming the second largest meat product category after pork in per capita consumption, and chicken liver, a by-product of chicken, accounts for 2% of each chicken. ~2.5%, and the annual output reaches more than 200,000 tons. Chicken liver has high nutritional value and contains protein, fat, carbohydrates, vitamin A, vitamin D, phosphorus and other ingredients. It is rich in iron and can nourish blood. In addition, the content of vitamin A in chicken liver is much higher than that of milk, eggs, meat, fish and other conventional foods. It has the function of maintaining normal growth and reproduction, and at the same time can pro...

Problems solved by technology

[0004] In order to overcome the shortcomings and deficiencies in the prior art that the utilization rate of chicken liver is not high, the enzymatic hydrolysis product has high content of bitter amino acids and heavy fishy smell, and cannot be used on a large scale, the primary purpose of the present invention is to provide a compound enzyme preparation for enzymatic hydrolysis of chicken liver
