Description
Technical field
The present invention relates to the food of fibroin, especially a kind of silkworm nest dry plate prepared with silk.
Background technique
Fibroin includes containing fibroin albumen and sericin, is rich in 18 kinds of amino acid, wherein the sweet ammonia of fibroin albumen
Acid, alanine, serine account for 70% or more, and the polarity pendant amino group acid of sericin accounts for 73% or more, are functional outstanding
Natural nutrient substance is widely used in biology, medicine, food, cosmetics, electronic material, leather and fabric etc..
Fibroin mostly is put into food in Japan, Taiwan etc., and in China, there is presently no be specially prepared into silk
The technique and equipment of food.The nutriment raw material that can directly eat, which is made, in silk there is no the best way, although it is existing by
The water-soluble fibroin powder (slightly band brown) for food of silk production, but be unfavorable for food processing application and can not ensure silkworm
Safety and sanitation of the silk-fibroin as raw-food material.
In view of this, Chinese invention patent application CN1152410 discloses the product silk essence after a kind of hydrolysis of fibroin albumen
And preparation method thereof, the silk after degumming is put into hydrochloric acid and is dissolved, was waited through back hydrolysis, filtering, decoloration, neutralization, precipitating
Journey can obtain silk essence, since silk essence is soluble easily in water, thus can be used for making cosmetics, food, drug etc..However, due to adopting
It being hydrolyzed with hydrochloric acid, salt is difficult to remove after neutralization, it will cause the excessive problem of product ash content, meanwhile, it can be containing certain in product
The harmful substance of amount, such as lead, arsenic, mercury, affect the application of fibroin.
Chinese invention patent application CN 104045841A discloses a kind of preparation method of silk fibroin hydrogel, will give up
Silk filters after aqueous sodium carbonate dissolution is repeatedly added, then homogenization obtains fibroin albumen water-setting after being dialysed with water
Glue, but this method is easy pollution fibroin, can not ensure the safety and health as raw-food material.
Chinese invention patent application CN101182348 discloses a kind of preparation method of frozen sericin gel, and this method is adopted
Carry out degumming with the distilled water boiled, be then concentrated, filter, dilution, freezing, thaw embathe after it is dry, this method is because use
Concentration method, glue yield rate is low, mentions that glue is insufficient, and preparative capacibility is low；Because preposition do not carry out clean control to silk cocoon, producing
In the process, Yao Jinhang impurity elimination is filtered, and will affect glue yield rate；Its integrated artistic silk gum purity is not high enough, will cause silkworm in silk cocoon
Sericin largely wastes, while being difficult to carry out the application of batch production and food processing.
Summary of the invention
In order to overcome the disadvantages mentioned above of the prior art, the object of the present invention is to provide a kind of silkworm nest prepared with silk is dry
Piece.
The technical solution adopted by the present invention to solve the technical problems is: a kind of silkworm nest dry plate prepared using silk, packet
Cotton-shaped fibroin preparation method is included, including cocoon cooking, gel and gel step again,
Wherein the cocoon cooking step includes:

High-temperature water, the silk cocoon in centrifugation cabin is rinsed, water-soluble fibroin is sufficiently refuted from being allowed to be dissolved into water, obtain
To silk protein solution；
The gel step includes:
Start the cooling system in cocoon cooking furnace, temperature be reduced to 80-90 DEG C, then opens cocoon cooking furnace bottom diaphragm valve,
The hypothermic saline pond that the sealed pipeline of silk protein solution is passed through to -20~0 DEG C, is circulated, fast cooling, makes silk egg
Water-soluble fibroin in white liquor tentatively condenses；
The gel step again includes:
After near 5~10 DEG C of water temperature, continue through sealing pipeline drainage pour into stainless steel charging basket, be placed in freezer after
Continuous frost 12h, makes the complete deep colling of silk protein solution at ice cube；
The caked silk protein solution of deep colling is placed in constant-temperature thawing room, and using thawing on 15 ° of inclination defrosting platforms, is solved
Freeze room temperature and be no more than 25 DEG C, after being filtered open-air, introduces defrosting room and thaw, the thawing mode was both energy saving
Silk protein solution is not polluted again；In course of defrosting, moisture content outflow is drained into blocking silk protein solution by the inclined-plane of defrosting platform
The rhone of lower section flows into defrosting water tank, and water-soluble fibroin condenses into cotton-shaped, and it is stand-by to collect cotton-shaped fibroin.
As a further improvement of the present invention: the high temperature and pressure centrifugal elutriation cocoon cooking furnace includes heated sealed furnace body, uses
