Novel technology for extracting threonine

Abstract

The invention discloses a novel technology for extracting threonine. Animal hair is used as raw materials, the animal hair is washed and cleaned up, immersed in 1%-2% of sodium hydroxide solutions for 4 hours and filtered, and filter liquor is used for preparing soluble protein. Acidolysis is conducted on solid substances in 5%-20% hydrochloric acid for 20-60 minutes, and the solid substances are stirred continuously. Precipitate is filtered out after standing for 60 minutes, and the threonine id obtained after the precipitate is dried.

Description

technical field [0001] The invention belongs to the technical field of resource utilization of waste, and more specifically relates to a threonine 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 ...
