Abstract
The invention discloses a kind of oxidation-resistant films, which is characterized in that the oxidation-resistant film is made of husky ginger extract, schizophyllum commune extract, vinegar, pectin, triethyl citrate, calcium lactate, modified starch, glycerol.The pure natural anti-oxidant, fungicide of plant extract is added in the present invention, safe and nontoxic, is a kind of a kind of edible, safe oxidation-resistant film that can be used for fruits and vegetables, meat antioxidation application.Present invention process is simple, convenient for operation, is conducive to promote.
Description
Technical field
The invention belongs to packaging material for food technical fields, and in particular to a kind of oxidation-resistant film.
Background technique
Brown stain is a kind of metachromatism generally existing in food, when especially fresh fruit of vegetables raw material is processed or through storing
After hiding or being mechanically damaged, the original color of food is dimmed, these variations belong to brown stain.In some food processing process,
Brown stain appropriate be it is beneficial, as soy sauce, coffee, black tea, the production of beer and bread, cake baking.And in other foods
In product processing, the especially process of fruit and vegetable, brown stain be it is harmful, it not only influences flavor, but also reduces nutriture value
Value, therefore understand the reaction mechanism of food brown stain, the approach for finding control brown stain has important practical significance.
Brown stain is divided into enzymatic browning (biochemical brown stain) by its mechanism occurred and non-enzymatic browning (non-biochemistry brown stain) two is big
Class.Phenolase is the terminal oxidase using oxygen as hydrogen acceptor, is the complex of two kinds of enzymes, one is (also known as phenol is hydroxylated cresolase
Enzyme), monohydric phenol is acted on, another is catecholase (also known as polynary phenol oxidase), acts on dihydric phenol.Also it is believed that phenol
Enzyme is the not strong enzyme of a species specificity that can be acted on monohydric phenol and act on dihydric phenol.Oxygen, more grace substances and polyphenol oxygen
Change the necessary condition that enzyme is enzymatic browning, frequently with reduction polyphenol content, passivation PPO enzymatic activity and reduces oxygen concentration
Measure.The research of antioxidant activity packaging suffers from significance to industries such as food industry, novel oxidation-resistant active packing
Research and development are the inexorable trends of active packing research.
A kind of oxidation-resistant film of the present invention will reduce PPO enzymatic activity and oxygen concentration measure be combined into one, to inhibit food brown
Become.
Summary of the invention
The present invention is intended to provide a kind of edible, safe oxidation-resistant film.
For achieving the above object, oxidation-resistant film of the present invention, the specific technical proposal is:
A kind of oxidation-resistant film of the present invention, the oxidation-resistant film is by husky ginger extract, schizophyllum commune extract, vinegar, pectin, lemon
Triethylenetetraminehexaacetic acid ester, calcium lactate, modified starch, glycerol composition.
A kind of oxidation-resistant film of the present invention, the oxidation-resistant film membrane material parts by weight are calculated as: 1-50 parts of husky ginger extract,
1-50 parts of schizophyllum commune extract, 1-45 parts of pectin, 1-25 parts of triethyl citrate, 1-35 parts of calcium lactate, is modified 1-30 parts of vinegar
1-25 parts of starch, 1-50 parts of glycerol.
A kind of oxidation-resistant film of the present invention, the oxidation-resistant film membrane material parts by weight are calculated as: husky ginger extract 10-25
Part, 10-25 parts of schizophyllum commune extract, 1-25 parts of vinegar, 10-35 parts of pectin, 1-20 parts of triethyl citrate, calcium lactate 5-25
Part, 9-20 parts of modified starch, 5-40 parts of glycerol.
A kind of oxidation-resistant film of the present invention, the oxidation-resistant film membrane material parts by weight are calculated as: husky ginger extract 14-18
Part, 14-19 parts of schizophyllum commune extract, 10-14 parts of vinegar, 18-22 parts of pectin, 5-10 parts of triethyl citrate, calcium lactate 10-12
Part, 15-18 parts of modified starch, 10-30 parts of glycerol.
A kind of oxidation-resistant film of the present invention, the oxidation-resistant film preparation method:
(1) blank film preparation: pectin being melted at 60-70 DEG C, glycerol, triethyl citrate, calcium lactate, modified starch is added,
It is stirred 30-60 minutes under the conditions of 100-1000rpm；70-80 DEG C is raised the temperature to again, is continued stirring 30-60 minutes, is obtained mixed
Close film liquid, after ultrasonic deaeration, pour into molding die, control film thickness between 0.01mm-0.02nm, 50 DEG C of dryings to get；
(2) husky ginger extract, schizophyllum commune extract are uniformly mixed with vinegar, put into automatic spray machine, mixed liquor is uniformly sprayed
In the face blank film A, coating does not spray again later then to 50 DEG C of dryings in the another face B, operates 3-5 times repeatedly, controls film thickness
Between 0.02mm-0.03nm to get.
A kind of oxidation-resistant film of the present invention, spray liquid and membrane area ratio described in the oxidation-resistant film preparation method are 1g:
100cm2。
