Abstract

A III type of protein peptide has main composition is protein, whose content is 90% or above 90% to it. The protein molecular weight is smaller than 2500D. Because the protein molecular weight is light, it is easy to be absorbed by human body. We extract collagen protein by the way of fermentation from the material of pig tail, or cattle tail. The collage protein is rich in nourishment and can be used to cutis protection. Its operation craft is easy and logical in the process with high efficiency, low cost, and is prone to industrialization.

Description

Little peptide of a kind of type iii protein and preparation technology thereof

Technical field

The present invention relates to field of biological product, little peptide of especially a kind of type iii protein and preparation technology thereof.

Background technology

Collagen protein also meets the theory of " dirty with dirty benefit " of the traditional Chinese medical science always as the good merchantable brand of skin care.Collagen protein in the present commercially available makeup all is that general animal skin is made raw material and made after enzymic hydrolysis, and molecular weight is greater than 5000D.This molecular weight has certain anaphylactogen characteristic greater than the collagen protein of 5000D, after allergic constitution uses, redness can occur, play rash, even anaphylaxis such as ulcer, and is serious even disfeature.Therefore, there is potential harm in the used for cosmetic of main component that traditional with the collagen protein is in skin care.

Summary of the invention

The purpose of this invention is to provide the little peptide of a kind of type iii protein, protein molecular weight is little, easily by skin absorption, does not have hazardness, and raw material is good, and preparation technology's science, reasonable is fit to suitability for industrialized production.

Technical solution of the present invention is:

The little peptide of a kind of type iii protein, main component are protein, and protein content is that protein molecular weight is less than 2500D more than 90% or 90%.

As a kind of preferred version, the protein molecular weight of the little peptide of type iii protein of the present invention is less than 1000D.

The preparation technology of the little peptide of type iii protein, raw material is oxtail and/or pigtail, processing step is:

A, oxtail, pigtail are cut into chunks, and separate glue wherein after the boiling;

B, with above-mentioned glue, adjust temperature to 40 ℃-60 ℃, transfer pH value 7.5-9, add compound protease and carry out enzymolysis; The conjugated protein enzyme dosage is the 0.2-1% of the contained total protein of glue, enzymolysis time: 3-5h; The enzymolysis solution enzyme that goes out, enzyme-removal temperature is 85-100 ℃, goes out 10-20 minute enzyme time; Go out enzyme rear decoloring, filtration are filtered rear decoloring liquid and are used molecular sieve filtration again, concentrate then, be drying to obtain.

As a kind of preferred version, when raw material is oxtail and pigtail, oxtail consumption 30%-70%, pigtail consumption 30%-70%.

As a kind of preferred version, the segment length 3-8 that ox, pigtail are cut into chunks in the steps A centimetre.

As a kind of preferred version, boiling autoclave after ox, pigtail are cut into chunks in the steps A, amount of water 1-2 times, vapor pressure 1.5-4kg, cooking time 2-5h.

As a kind of preferred version, enzymolysis solution goes out and is cooled to 20 ℃-80 ℃ behind the enzyme among the step B, adds gac 1.5-3% decolouring, time 30-60 minute.

As a kind of preferred version, the hydrolyzed solution among the step B after the decolouring filters with plate-and-frame filter press, and filter material cloth is selected the pure cotton canvas of 4 * 4-8 * 8 for use, and pure cotton canvas uses after 0.2%-1% dilute alkaline soln degreasing post rinsing is clean; Filter with microporous membrane is smart behind the Plate Filtration.

As a kind of preferred version, the drying among the step B is vacuum-drying or spraying drying; During spraying drying, the equipment importation hot blast temperature is 90 ℃-140 ℃, and the outlet hot blast temperature is 30 ℃-70 ℃.

The little peptide of type iii protein provided by the invention, protein content are more than 90% or 90%, and protein molecular weight is less than 2500D, below the preferred 1000D.Produce with ox, pigtail, ox, pig health are unique to be tail not stopping transport moving, and the collagen protein in the tail is fit to the maintenance of skin very much.Pass through advanced compound protease enzyme solution in the preparation, through molecular sieve filtration, the gained protein small peptide, molecular weight is little, and is nutritious, and no anaphylaxis is the good merchantable brand of skin care.Simultaneously, preparation technology is scientific and reasonable, and is easy to operation, the efficient height, and cost is low, is suitable for suitability for industrialized production.
