Problems solved by technology

However, people often use single-enzyme hydrolysis, and its hydrolysis efficiency is not high
At the same time, because in the prior art, after the enzymatic hydrolysis step, there is no effective further processing step to submit the product quality, and the traditional cooking concentration and drying steps cause the nutritional value of the product to decrease, and the ash content of the product is high, which is difficult for absorption and digestion. The rate is low, and the appearance of the product does not meet the requirements, so it is difficult to produce high-quality products

Abstract

The invention relates to a method for producing fibrin polypeptide powder (pig blood fibrin polypeptide powder) via hydrolyzing blood clots of pig blood. In the processes of collecting, storing and processing pig blood, the principal component of the blood clots generated via blood clotting is fibrin; and separation and cutting, enzymolysis via proteinase preparation, enzyme deactivation, filtration and drying via atomizing are carried out on the blood clots, thus, the pig blood fibrin polypeptide powder is obtained. By means of the technical scheme provided by the invention, fibrin polypeptide is produced via the enzymolysis of the blood clots; when the fibrin polypeptide is used as a feed additive, the pollution is reduced and the green environmental protection requirements are met; andwhen the fibrin polypeptide is used as an excellent animal protein source, the digestibility of the protein is improved and the trend of the upgrading of the current enterprise technologies is met.

Description

Technical field [0001] The invention relates to a proteolysis and production technology of pig feed additives, in particular to a preparation method of an enzymatic hydrolysis polypeptide powder of pig blood fibrin. Background technique [0002] my country's pig blood resources are very rich. About 1.5 million tons of pig blood are slaughtered and produced each year, of which about 300,000 tons of high-quality protein are contained. It is one of the largest animal protein resources. In the development and utilization of pig blood, due to insufficient anticoagulation of some blood, a large number of blood clots will be produced, which will adversely affect the deep processing technology of pig blood. For a long time, pig blood processors often discard these blood clots, which will not only pollute the environment, but also waste valuable protein resources. [0003] At present, when people hydrolyze proteins, they often choose to use acid, alkali or enzymes for hydrolysis. Acid-base...
