Process for producing amino acid from blood of slaughtered livestock and poultry

Abstract

The invention discloses a process for producing amino acid from blood of slaughtered livestock and poultry and belongs to the technical field of biochemistry. The process comprises the following steps: (1) filling blood in a storage tank under normal temperature and normal pressure, and transporting or intensively storing the blood; (2) treating the raw material of the blood, mixing coagulated plasma with water according to a ratio of 8 to (1.5-3), stirring for more than 20 minutes by using an OH radical multistage pump, wherein the OH radical can effectively break blood cell membranes; (3) filtering the raw material via a filter net, feeding the raw material into a reaction tank for carrying out hydrolysis reaction under the reaction temperature of 45-60 DEG C, mixing the raw materials with water according to a ratio of 7 to (2.5-3.5), stirring at a pH value of 7.3-7.6, and carrying out hydrolysis reaction for 5-7 hours via 0.3-0.5% by mass of protein hydrolase; (4) forming amino acid after enzymatic hydrolysis reaction, and filtering foreign matters in the amino acid for twice via a 200-250-mesh filter net; (5) carrying out sterilization treatment; and (6) feeding the amino acid into the storage tank for storing, and packaging. The process for producing amino acid from blood of slaughtered livestock and poultry has the advantages that the pollution is completely avoided, the blood nutrition is not lost, the amino acid is not broken, the hydrolysis time is short, the investment is low, and the production cost is low; therefore, the process is simple and efficient.

Description

technical field [0001] The invention belongs to the field of biochemical technology. Background technique [0002] Due to the huge number of pigs, cattle, livestock, chickens, ducks and poultry slaughtered in my country every year, the amount of blood produced after slaughtering livestock and poultry is also amazing, and most of them are not effectively used and discarded, which not only wastes a lot of precious resources, but also affects The environment is polluted. [0003] At present, the scope of reuse of part of slaughtered animal blood is in the fields of blood clots, rice sausage, etc., raw materials for medical medicine, dry blood meal feed additives, etc., but there are still quite a few parts that are discarded. [0004] According to the "London Convention (International Convention on the Prohibition of Maritime Speculation)", since 2013, the path of ocean dumping of slaughtered blood has been banned from the root cause. The ground treatment of waste blood is ...

AI Technical Summary

Problems solved by technology

[0008] The sterilization process should be carried out within the range where the protein structure can be completely converted into amino acids and their deformations. Therefore, the use of chemical drugs and high-temperature heat treatment methods do not meet the requirements for obtaining high-quality amino acids. If cost and management are considered, high pressure, freezing, compression, etc. All methods require a large investment of funds and management costs, and they cannot be completely converted into amino acids. Therefore, they are not ideal and effective methods. There are still various complicated problems in the effect level of ultraviolet rays and ultrasonic waves.
