Description

technical field

[0001] The invention relates to a method for extracting medicine, food and daily cosmetic raw materials, in particular to a method for extracting silk fibroin from cocoon shells and cocoon threads. Background technique

[0002] Cocoon silk fiber is composed of 20-30% sericin protein and 70-80% silk fibroin protein. Silk protein is composed of 18 kinds of amino acids, but in sericin protein, it also contains 3% cocoon silk Carbohydrates, inorganic substances, waxes and pigments, while silk fibroin is the main body of cocoon silk, its protein content is very high, and it is a high-molecular protein, and its amino acid composition is very rich. It has been widely used as raw materials for medicine, food and cosmetics. At present, there are mainly the following methods for extracting silk fibroin:

[0003] 1. Water boiling method: Boil in a degumming pot and keep boiling evenly for 15-20 hours. Most of the sericin can be removed, and it has a slight effect on si...
