Problems solved by technology

[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
The traditional animal hair extraction is mostly enzymatic hydrolysis, the technical requirements are relatively high, the cost is relatively high, and the economic benefits of industrial production are not high.

Embodiment Construction

[0005] The animal hair is cleaned, soaked with 1-2% sodium hydroxide solution for 4 hours, filtered, and the filtrate is used as the preparation of soluble protein. Acid hydrolyze the solid substance with 5-20% hydrochloric acid for 20-60 minutes, keep stirring, let it stand for 60 minutes, filter out the precipitate, and dry it to obtain tryptophan.

Abstract

The invention discloses a novel process of extracting tryptophan. Animal hair is used as raw materials, the animal hair is cleaned up and soaked in 1-2% of sodium hydroxide solutions for four hours and filtered, wherein filtrate is used for preparing soluble protein. Acidolysis is conducted on solid substances through 5-20% of hydrochloric acid for 20-60 minutes, and the solid substances are constantly stirred. After standing for 60 minutes, precipitates are filtered. After the precipitates are dried, the tryptophan is formed.

Description

technical field [0001] The invention belongs to the technical field of resource utilization of waste, and more specifically relates to a preparation technology of tryptophan. 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-sav...
