Novel technology for extracting leucine

Abstract

The invention discloses a novel technology for extracting leucine. According to the novel technology for extracting the leucine, animal hair is used as a raw material. The novel technology for extracting the leucine includes the following steps: firstly, the animal hair is washed cleanly and then soaked in sodium hydroxide solution with the concentration of 1-2% for four hours; and secondly, the animal hair and the sodium hydroxide solution are filtered to obtain filtrate, and the filtrate is used for preparing soluble protein. Solid matter is subjected to acidolysis for 20 to 60 minutes in hydrochloric acid with the concentration of 5-20%, the solid mater and the hydrochloric acid are stirred continuously, after standing for 60 minutes, sediment in the solid matter and the hydrochloric acid is filtered to obtain filtrate, and then the filtrate is dried to obtain the leucine.

Description

technical field [0001] The invention belongs to the technical field of waste resource utilization, and more specifically relates to a leucine preparation technology. Background technique [0002] Animal hair is rich in resources. Traditionally, animal hair is generally used as a raw material for brushes, with relatively low added value. At the same time, hair contains a large amount of active proteins, amino acids, lysine and other active substances. However, traditional animal hair extraction is mostly enzymatic hydrolysis, which requires relatively high technical requirements and high costs, and the economic benefits of industrial production are not high. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art and provide a new hydrolysis method, which can not only effectively extract and separate the active substances in animal hair, but also has the advantages of efficient, fast, complete and time-saving extra...
