Description
Technical field
The invention belongs to casing processing technique field, relate to a kind of collagen protein and be combined casing film with wheat protein
And preparation method thereof.
Background technology
Collagen protein is the primary raw material preparing edibility casing at present.But the technology of preparing of collagen is the most complicated,
Complex steps, needs substantial amounts of saturated limewater for dissolution animal endothelium and for right during preparation
Animal endothelium carries out being acidified the acidifying solution of swelling, produces substantial amounts of acid-base waste fluid in the middle of this, and environmental pollution is relatively
Big and relatively costly.
Semen Tritici aestivi is one of three big Major Cereals in the world.Wheat gluten protein is the main component of wheat protein,
It is made up of gliadin and glutenin, containing substantial amounts of disulfide bond and other hydrophobic bonds etc., has very
Good film property；And wheat gluten protein is rich in 18 kinds of aminoacid, it is nutritious, inexpensive planting
Thing albumen is originated, and wherein the content of saccharide and fat is extremely low, and this meets current low sugar and low-fat requirement very much.
Wheat gluten protein is owing to containing more hydrophobic amino acid, the dissolubility in water is the least, and relatively low is molten
Xie Du greatly limit the range of application of wheat protein.
Summary of the invention
Problem to be solved by this invention is: provide a kind of cheap, environmental pollution is less, material
Tensile strength and elongation at break collagen protein bigger, edible are combined casing film and system thereof with wheat protein
Preparation Method.
It is an object of the invention to be achieved through the following technical solutions: according to an aspect of the present invention, it is provided that
A kind of collagen protein is combined casing film with wheat protein, it is characterised in that described collagen protein is multiple with wheat protein
Close each raw material components of casing film according to following weight portion mixing composition: collagen protein 20～30 parts；Wheat protein
6～10 parts；Plasticizer 6～10 parts；3～5 parts of sodium carboxymethyl cellulose；Ethanol 40～50 parts；Distilled water 200～300
Part.Preferably, described wheat protein is the main component of wheat gluten protein, i.e. wheat protein.
According to a further aspect in the invention, it is provided that a kind of collagen protein and wheat protein are combined the system of casing film
Preparation Method, comprises the following steps that:
A, Feedstock treating: wheat protein is done dissolution process, first configuration 250-300 part concentration of alcohol is
10-30%, pH value are the solution of 10.0, add 6～10 parts of wheat protein, stir 30 minutes with agitator,
Obtain the homogeneous wheat protein solution being completely dissolved；
B, mixed processing: the sodium carboxymethyl cellulose of 20～30 parts of collagen protein and 3～5 parts is joined mixing
In uniform wheat protein solution, stir 30 minutes with agitator, make solution be sufficiently mixed, regulate molten simultaneously
Liquid pH value is 9.0～10.0, adds 6～10 parts of plasticizers and mass ratio 0.1～the glutaraldehyde cross-linking agent of 0.3%,
At regulation temperature to 40 DEG C, heating in water bath is sufficiently stirred for 30 minutes obtaining uniform film forming liquid；
C, film forming are dried: film forming liquid carries out casting film-forming, and then at a temperature of 40 DEG C, forced air drying obtains intestinal
Clothing film semi-finished product；
D, maturation process: carry out under the conditions of temperature 65～75 DEG C and relative humidity 85～95% at the ripening of 24h
Reason, the quality finally giving casing film finished product is homogeneous and relatively soft.
Preferably, any one during above-mentioned plasticizer at least includes glycerol, Polyethylene Glycol, sorbitol.
Further, any one during above-mentioned plasticizer can only include glycerol, Polyethylene Glycol, sorbitol
Material can also include the arbitrary proportion mixture of above-mentioned three kinds of materials.
Preferably, collagen protein described above and wheat protein be combined edibility casing film can be used for casing and
Its food pack.
The invention have the advantage that
(1) collagen protein that the present invention develops and wheat protein are combined edibility casing film and combine two kinds merely
The advantage of albumen edibility casing film.Compared with collagen protein edibility casing film, in tensile strength and fracture
In the case of percentage elongation is more or less the same, reduce environmental pollution；Due to the addition of wheat protein, production cost
Reduced the most further for raw material so that nonpolar amino acid quantity and hydrophobic group increase, egg
The water-resistance of white composite membrane increases.Compared with wheat protein edibility casing film, improve the tension of film
Intensity, thus meet the needs of more products packaging.
(2) wheat protein has good film property, and it is former to be that Substitute For Partial collagen protein prepares the ideal of casing
Material.Semen Tritici aestivi is one of three big Major Cereals in the world, and wheat protein raw material sources are extensive, cheap.Little
Wheat mucedin is the main component of wheat protein, is made up of gliadin and glutenin, containing big
The disulfide bond of amount and other hydrophobic bonds etc., have good film property；And wheat gluten protein is rich in 18 kinds
Aminoacid, is nutritious, inexpensive vegetable protein sources, and wherein the content of saccharide and fat is extremely low,
This meets current low sugar and low-fat requirement very much.
(3) this product overcomes the problem that collagen protein can not be mixed thoroughly with wheat protein, by using
The solution of the certain concentration of alcohol under the conditions of alkalescence, it is possible to collagen protein and wheat protein are completely dissolved mixing,
The film forming liquid being uniformly mixed, and then use casting film-forming to obtain casing film.
(4) albumen that the present invention develops is combined casing film mainly by collagen protein, wheat protein, carboxymethyl
Prepared by sodium cellulosate, glycerol, water, have edibility, and nutritive value is higher；
(5) albumen that the present invention develops is combined casing film, modified through composite elasticizer, cross-linking agent, compound
The elongation at break of film and hot strength have and improve largely；
(6) collagen protein that the present invention develops and wheat protein are combined edibility casing film, its production technology letter
Single, equipment is simple；
(7) collagen protein and wheat protein are a kind of reproducible natural polymer child resources, have and take it
The most nexhaustible advantage.
