Abstract

The invention discloses an edible membrane by taking proanthocyanidins crosslinked with collagen as matrix and a preparation method thereof. In the method, firstly, proanthocyanidins water solution with the mass concentration of (0.1-0.5) per mill and collagen water solution with the mass concentration of (1-5) per mill are prepared respectively; then, the proanthocyanidins water solution and the collagen water solution are mixed according to the dry weight ratio of 1:50-4:50 in the stirring state; next, the mixed solution is stirred evenly to form membrane solution; and finally, membrane making is carried out to obtain the edible membrane. The edible membrane prepared in the method has good grease oxidization resistance, antibiotic property and separation property, simple preparation method and easy operation. In addition, the edible membrane has wide application scope, can be applied for inner packing of the grease food, the frozen food, the medicine electuary and the convenience food and has greater application and promotion value.

Description

A kind of taking proanthocyanidins crosslinked with collagen is edible film of matrix and preparation method thereof
Technical field
The present invention relates to a kind of edible membrane material and preparation method thereof, have good anti-Oxidation of Fat and Oils, germ resistance, barrier in particular to a kind of, and safety non-toxic is biodegradable, can be used in edible film of food internal packing and preparation method thereof.
Background technology
Edible packaging film is mainly used in food fresh-keeping in transportation, storage and shelf storage process, need mould material in the biodegradable while of safety non-toxic, also have good gas-barrier properties, fragrance protectiveness, the vapour perviousness that blocks water, dubbin perviousness, stability and a mechanical property preferably.
Protein has the characteristics of originate abundant, biodegradable and safety non-toxic, is widely used in edible packaging film as the film forming substrate.Collagen is a kind of natural protein, extensively is present in skin, bone, muscle, heel string, ligament and the blood vessel of animal, and be structural protein important in reticular tissue, the cartilaginous tissue.The molecular weight of collagen is big, and solvability is little, has good film-forming properties.And the triple helix structure that collagen is natural and self be fibrous texture closely, makes collagenic material demonstrate very strong toughness and intensity, is applicable to the preparation mould material.
The barrier property of simple collagen film and mechanical property are all limited.Force of cohesion increase between the protein peptide chain is the important factor that improves the film barrier property, can come the stable of induced protein by the formation of hydrogen bond, electrostatic interaction and covalent linkage.In the research often by proteinic chemically crosslinked, enzyme is crosslinked or physical treatment improves its barrier property and mechanical property.Pycnogenols is a kind of plant polyphenol that is widespread in nature, and has stronger antibacterial, anti-oxidant and capability of resistance to radiation, is mainly used in food, beverage, healthcare products and cosmetic field.Contain more phenolic hydroxyl group, alcoholic extract hydroxyl group and ether in the pycnogenols molecule, easily with collagen on hydroxyl, amino and carboxyl form hydrogen bond, thereby produce crosslinked, the barrier property and the mechanical property of raising collagem membrane.Therefore, pycnogenols is a kind of collagen crosslinking agent of effective safety non-toxic.
At present, there have been some patents that collagen base edible film is disclosed.Disclose a kind of edible film and production method thereof that contains collagen of fish skin as CN101341977.Patents such as CN1547434, CN1154797, CN1337179, CN1228922 are to being that the method that main raw material is made casing discloses with collagen.CN1723803 discloses a kind of natural membrane forming preservation agent used for crystal-like delicious meat that contains tea-polyphenol and collagen protein, but just a kind of additive of tea-polyphenol as preservation agent used, do not use, and what wherein adopt is not the collagen that the triple helix structure remains intact as main component.The mechanical property of these edible films, swelling behavior, barrier property and anti-Oxidation of Fat and Oils ability are still waiting to improve, and are that the edible film of matrix does not also have document and patent report with the taking proanthocyanidins crosslinked with collagen with good resistance of oxidation.
The invention provides a kind of taking proanthocyanidins crosslinked with collagen is edible film of matrix and preparation method thereof.This edible film is the biodegradable natural fresh-keeping film of a kind of safety non-toxic, have good anti-Oxidation of Fat and Oils, germ resistance and barrier property, and the preparation method is simple, and profit margin is big.In addition, this edible film use range is wider, can be applied to the internal packing of lipid food, frozen product, medicine instant and ready-to-eat, has good market application prospect.
Summary of the invention
The object of the present invention is to provide a kind of taking proanthocyanidins crosslinked with collagen is edible film of matrix and preparation method thereof, consumable film is reached have the effect of bacteriostasis, anti-Oxidation of Fat and Oils ability by add pycnogenols in collagen.
For reaching above purpose, the present invention is by the following technical solutions: prepare mass concentration at first respectively and be the pycnogenols aqueous solution of (0.1-0.5) ‰ and the mass concentration collagenic aqueous solution for (1-5) ‰, under whipped state pycnogenols and collagen solution are pressed dry weight than 1 then: 50-4: 50 mix, stir and form film forming liquid, and after the system film obtain.Above described film-forming method for film forming liquid pour into the system film die in, natural air drying or in 20-35 ℃ of baking oven the oven dry after take off film.
Edible film of the present invention can be applied to the internal packing of lipid food, frozen product, medicine instant and ready-to-eat.
Compare with existing edible film, adopt the material of the present invention's preparation to have the following advantages:
(1) it is little that the collagen that remains intact for the triple helix structure of the raw material that adopts of the present invention, the edible film of preparation have a swelling ratio, the characteristics that water preventing ability is good;
(2) edible film of the present invention's preparation has good anti-Oxidation of Fat and Oils and germ resistance, is the biodegradable natural fresh-keeping film of a kind of safety non-toxic;
(3) the edible film use range of the present invention's preparation is extensive, can be applied to the internal packing of lipid food, frozen product, medicine instant and ready-to-eat;
(4) preparation method of edible film disclosed by the invention, easy handling, with short production cycle, have bigger application and popularization value.
