Description

A kind of plants essential oil soybean separation protein tunica albuginea and preparation method thereof
Technical field
The invention discloses a kind of plants essential oil soybean separation protein tunica albuginea and preparation method thereof, belong to high polymer material technology Field.
Background technology
Oxidation causes food that a series of quality deterioration reactions occur, and spoiled, the peculiar smell generation that such as changes colour, nutritive value reduce Deng having a strong impact on its shelf stabilities, be one of the subject matter that food enterprise faces.In order to delay or suppress the oxidation of food Reaction, antioxidant generally is sprayed to food substrate doping or food surface, but because most of oxidation reaction is concentrated in Food surface, the direct addition of active material make it diffuse rapidly into food system, cause the reduction of food surface concentration.It is and living Property agent be also possible to food substrate occur neutralization reaction reduce further its antioxidation activity；And increase the starting of antioxidant Concentration may result in prooxidant effect.Anti-oxidant controlled release packaging material can effectively solve this problem, and it is embedded using material The active packing system that antioxidant is formed, by the appropriate active factors of food surface sustained release, realizing permanently effective Suppress the purpose of Food Oxidation reaction.Therefore, active packing system not only acts as iris action, and during food selling Positive protective effect is also played to food quality.
Immense pressure in view of conventional synthesis plastic material to environment, natural degradable or edible boilogical sill, Such as polysaccharide, protein and lipid have extensive development prospect.Albumen base film is due to its unique gas selective penetrated property And the common concern of the barrier property outstanding to oxygen, carbon dioxide by researcher in low moisture environments.Wherein, soybean separation protein Also there is abundance, filming performance cheap, biodegradable, nutritive value is high and outstanding in vain.In addition, phase Than other plant albumen, there is more preferable flexibility, slickness, water solubility and clarity；Simultaneously also have preferable edibility, The advantages that degradability and non-environmental-pollution, have and effectively solve " white pollution " problem that traditionally non-degradable plastic tape comes Potential, the theory of " green " is embodied, so it is irreversible trend to substitute common plastic material.But soybean Also there is the problem of inoxidizability and bad mechanical property in protein isolate film, therefore, also need to study it.
The content of the invention
The present invention solves the technical problem of：For traditional soybean protein isolate film inoxidizability and mechanical property not A kind of the problem of good, there is provided plants essential oil soybean separation protein tunica albuginea and preparation method thereof.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
A kind of plants essential oil soybean separation protein tunica albuginea, it is characterised in that：It is made up of the raw material of following parts by weight：10~20 parts Soybean separation protein white powder, 10~20 parts of plants essential oils, 5~8 parts of Fruit peel extracts, 4~6 parts of vegetable waxs, 2~3 parts of reducing agents, 1 ~2 parts of crosslinking agents, 3~4 parts of plasticisers, 70~100 parts of distilled water, 3~4 parts of calcium chloride, 3~4 parts of citric acids, 2~3 parts of surfaces Activating agent；
The preparation process of the plants essential oil soybean separation protein tunica albuginea is：
（1）Each raw material is weighed by raw material composition；
（2）Soybean separation protein white powder is mixed with distilled water heating stirring, obtains soybean protein solution；
（3）Plasticiser is added into above-mentioned gained soybean protein solution, heating stirring mixing, obtains mixed slurry；
（4）Above-mentioned gained mixed slurry pH to 9.9~10.2 is adjusted, obtains alkaline mixed slurry；
（5）Plants essential oil, Fruit peel extract, vegetable wax, reducing agent, crosslinking agent, chlorine are added to above-mentioned gained alkalescence mixed slurry Change calcium, citric acid, surfactant mixing, heating stirring reaction, obtain into film liquid；
（6）Above-mentioned gained film liquid is subjected to homogeneous, obtains homogeneous into film liquid；
（7）Above-mentioned gained homogeneous film forming liquid stream is prolonged on polypropylene plastics flitch, dried, and uses scraper knifing, it is smart to produce plant Oily soybean separation protein tunica albuginea.
The plants essential oil is Lavender, any one in rose ethereal oil or jasmine essential oil.
The preparation process of the Fruit peel extract is：Pericarp is dried, crushes, obtains dry pericarp powder；Gained is dried Pericarp powder and water in mass ratio 1：50~1：100 heating stirrings mix, and filtering, obtain Fruit peel extract；The pericarp is apple Skin, any one in peach skin or pear skin.
The reducing agent is any one in vitamin C or glucose.
The crosslinking agent is by n-hydroxysuccinimide and maleimide in mass ratio 1：1 mixes.
The plasticiser is any one in glycerine or sorbierite.
The surfactant is Tween-60, any one in Tween-80 or Si Pan -80.
The beneficial effects of the invention are as follows：
（1）Present invention addition plants essential oil, first, plant-derived essential oil occupies the amount of activated group in soybean protein skeleton Position, reduce the oscillation intensity of covalent bond in soybean protein molecule, meanwhile, the freedom of hydrophilic bond can be formed in film with water Hydrogen group is reduced, and the water content of system reduces, so as to which promotion system is crosslinked so that form the tensile strength and elongation at break of film Get a promotion, meanwhile, by adding vegetable wax, on the one hand, vegetable wax is covered in film surface, on the one hand, strict control moisture enters Enter in film, promotion system is further crosslinked so that the tensile strength and elongation at break of film further get a promotion, the opposing party Face, play a part of obstructing air, strengthen the antioxygenic property of film, in addition, containing antioxidant content in plants essential oil, strengthen film Antioxygenic property；
（2）For the present invention by adding calcium chloride and citric acid, calcium chloride ionizes out calcium ion in water, in preparation process, one Aspect, due to containing two carboxyls in citron acid molecular structures, the carbonylic oxygen atom on two carboxyls is given as electron-donating group Go out the lone pair electrons of its outer layer, calcium ion receives the lone pair electrons of oxygen atom with unoccupied orbital, another so as to form Coordinative Chemistry key Aspect, because force ratio is weaker between calcium ion and water, so that soybean protein strand and calcium ion interaction force It is relatively strong, so soybean protein strand forms stable three-dimensional network by coordination bond cross-linking, lift the tensile strength of film and break Split elongation；Meanwhile by adding reducing agent, sulfydryl in system is reduced so that the intermolecular further crosslinking of soybean protein, increase The crosslink density of strong system, further lift the tensile strength and elongation at break of film；
（3）The present invention first, contains antioxidant content, strengthens the antioxygen of film by adding Fruit peel extract in Fruit peel extract Change performance, secondly, Fruit peel extract contains a large amount of active components, and active component can promote sulfydryl to reduce so that soybean protein point Further it is crosslinked between son, strengthens the crosslink density of system, further lifts the tensile strength and elongation at break of film.
