Abstract

The invention relates to a production process for extracting cystine by hair. The production process for extracting cystine by hair is characterized by comprising the following steps: step 1, preparing a cystine crude product by animal hair; step 2, treating the cystine crude product; and step 3, preparing a cystine finished product. The production process for extracting cystine by hair disclosed by the invention is scientific and reasonable in design, low in production cost, high in product purity and high in hair recovery rate. According to the production process for extracting cystine by hair disclosed by the invention, impurities are removed by neutralization and decolouration three times to purify the product, thus the quality of the product can achieve the standards of pharmacopoeia, AJI92 and USP (United States Pharmacopoeia), and economic value is greatly increased.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, in particular to a production process for extracting cystine from hair.
