Abstract
The present invention relates to a silk protein preparing technology. Silk vomited by silkworms, or floss silk, or silkworm bodies, or silkworm chrysalises are adopted as raw material. The raw material of floss silk of animal protein is tightly frozen in the environment whose temperature is from-8 DEG C to 10 DEG C. After silk-shaped substances are frozen, silk planing operation is carried out, and the silk-shaped substances are planned into little granules. The little granules are unfrozen and dewatered. After dehydration, silk-shaped granules are dried. After dryness, the granularity of the silk-shaped granules is equal to 60 meshes in general. The silk-shaped granules are pulverized for the second time. The silk-shaped granules are pulverized in single cycle equipment by a high pressure draft clash technology, and the granularity of the pulverized granules is equal to 300 meshes. Finally, powdered substances are added into a two-cycle liquid nitrogen jet type refrigeration high pressure draft disintegrator to be frozen until the temperature reaches-10 DEG C, and the powdered substances are pulverized. After the silk protein of the present invention is prepared, the granularity of the silk protein can reach more than 2000 meshes, original organic substances are not destroyed, the silk protein can be dissolved in water, the silk protein can be used in formulations of various kinds of health food and various cosmetics, the silk protein can be used as an additive agent of cosmetics, and the beauty treatment function of skin can be increased.
Description
Technical field
The present invention relates to the preparation method of animal protein, particularly a kind of preparation method of silk fibroin powder.
Background technology
Along with the continuous development of medical technology, in engineered research and use and to need a large amount of silk proteins,, more need a kind of silk protein to develop targetedly and carry out physiotherapy particularly in today that medical skill is constantly brought forth new ideas.
Traditional health food and cosmetics need upgrading, and required animal protein adopts general preparation technology in preparation process, for example raw material is dried and pulverized.But this kind oven dry is just made different animal proteins according to different raw materials with pulverizing.
Summary of the invention
Task of the present invention provides a kind of preparation method of silk fibroin powder, and it has solved general preparation technology's problem of animal protein.
Technical scheme of the present invention is as follows:
A kind of preparation method of silk fibroin powder adopts the silkworm body to make raw material, takes the following step:
First step:, closely be placed on temperature and be in-8 ℃～-10 ℃ the environment freezing with animal protein silkworm bulk stock;
Second step: treat that the silkworm body digs an operation after freezing, digs into fine particle;
Third step: the dehydration of thawing then, drying is carried out to filamentous particle in the dehydration back, and dried filamentous particle granularity is generally 60 orders;
The 4th step: carry out the second time again and pulverize, adopt the high pressure draught colliding technique filamentous particle to be pulverized grain graininess to 300 order of pulverizing in single cycle equipment;
The 5th step: freezing with carrying out in the two circulating liquid nitrogen spray type refrigerating high pressure draught pulverizers of coccoid adding at last, pulverize for-10 ℃ until temperature.
Silk fibroin powder of the present invention is after preparation, and its granularity can reach more than 2000 orders, can keep original organic substance not to be damaged, be dissolvable in water water, the prescription that is used for various health foods and cosmetics as the additive of cosmetics, can increase the beautification function of skin.
The specific embodiment
Below embodiments of the invention are elaborated.
A kind of preparation method of silk fibroin powder adopts the silkworm body to make raw material, takes the following step:
First step:, closely be placed on temperature and be in-8 ℃～-10 ℃ the environment freezing with 100% animal protein especially silkworm bulk stock.
Second step: treat that the silkworm body digs an operation after freezing, digs into fine particle.
Third step: the dehydration of thawing then, drying is carried out to filamentous particle in the dehydration back, and dried filamentous particle granularity is generally about 60 orders.
The 4th step: carry out the second time again and pulverize, adopt the high pressure draught colliding technique that filamentous particle is pulverized in single cycle equipment, about grain graininess to 300 order of pulverizing.
The 5th step: freezing with carrying out in the two circulating liquid nitrogen spray type refrigerating high pressure draught pulverizers of coccoid adding at last, pulverize for-10 ℃ until temperature.The pulverization principle of this kind equipment is that freezing limit, limit high pressure draught is pulverized.Coccoid grinding particle size the best can reach more than 2000 orders.
Preparation technology of the present invention requires to operate under germ-free condition.
