Novel process of histidine extraction

Abstract

The invention discloses novel process of histidine extraction. Animal hair is used as raw materials, the animal hair is washed cleanly and soaked in 1%-2% of sodium hydroxide solutions for 4 hours, the solution is filtered, and filter liquor is used for preparing soluble protein. Acid hydrolysis is carried out on solid substances for 20-60 minutes by using of 5%-20% hydrochloric acid, the solid substances and the hydrochloric acid are stirred ceaselessly, precipitate is filtered out after standing for 60 minutes, and histidine is obtained after the precipitate is dried.

Description

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