Description
Technical field
The present invention relates to a kind of preparation method of the coating antistaling agent based on beeswax aqueous dispersion.
Background technology
Annual China's gardening product rotting rate caused by the factor such as postharvest handling and packaging rots to damage more than 20%
Up to more than 200,000,000 tons of consumption, direct economic loss reaches hundreds billion of first people.China's fruits and vegetables industry is faced because preservation technology falls behind and produces
The problems such as fruit and vegetable food shelf life caused by the research of product shelf life is weak is short, product quality is not high, category is single, greatly hinders
The healthy benign development of China's fruits and vegetables industry.
Coating-film fresh-keeping material is the mainstream technology for being applied to antiseptic preservation of fruits and vegetables at present, and the technology uses edible natural thing
Matter (such as polysaccharide, protein, fat, plant wax class etc.) is material, adds plasticizer, crosslinking agent of edibility etc., passes through difference point
Interaction between son, and food surface (or internal) is covered in forms such as parcel, coating or microcapsules, form protection and made
Thin layer, with the infiltration of microbial barrier, aqueous vapor, oxygen or various solutes.Applied as 102369972A discloses a kind of chicken
Film antistaling agent, is made up of vegetable oil, beeswax, starch, vitamin C, glyceryl monoacetate, sodium benzoate, water.104286165A is disclosed
A kind of porous material composite coating preservative of controllable breathing, solve fruit it is perishable go bad, generate alcohol, be difficult it is fresh-keeping
And not storage tolerance the problem of, the antistaling agent component is：Porous material 0.05~1.5%, beeswax 10~20%, vitamin e1~
2%th, pectin 3~5%, lignin 2~4%, cosolvent 0.5~1.5%, dispersant 2-4%, water 30-40%.Other films
Antistaling agent is formulated by the one or several kinds in pulullan, glycerine, water-repelling agent, sorbierite, preservative etc..
But existing edible coating-film fresh-keeping material is primarily present the deficiency of following several respects：1. product quality is kept after film
Undesirable, easily by microorganism pollution, shelf life is shorter；If 2. with reference to air conditioned storage or cryopreservation, although fresh-keeping effect compared with
Ideal, but cost is higher；3. other preservatives are added in coating liquid can improve product quality and shelf life, but have certain
Residual, Consumer acceptance is high；4. use individual layer technology for coating more edible film, be usually used in adopting for livestock products or complete fresh fruit
It on fresh-keeping afterwards, can not be taken into account with antibiotic property and prevent-browning, hinder moist and gas barrier property and the defect such as can not take into account, be not suitable for
Fruit and vegetable food, and to the security Shortcomings of the fresh-keeping edible class coating material of its novel anticorrosion, there is food security hidden danger.
The content of the invention
The purpose of the present invention is to be directed to above-mentioned present situation, it is desirable to provide a kind of overall safety, nontoxic；It is easy to film forming after drying,
And film forming has water proofing property, stability, at room temperature in flow regime；Have preferable bacteriostatic activity based on beeswax aqueous dispersion
Coating antistaling agent preparation method.
The implementation of the object of the invention is that a kind of preparation method of the coating antistaling agent based on beeswax aqueous dispersion has
Body step is as follows：
1) 10g~25g polysaccharide is dissolved in 300g-500g pure water or weakly acidic water, and is heated to 60~80 DEG C
Prepare polysaccharide solution；
The polysaccharide is：Chitosan, Propiram, xanthans, carboxymethyl cellulose, sodium alginate, carragheen, carboxymethyl shell
It is one or more compound in glycan, konjaku glucomannan；
When polysaccharide used is chitosan, the slightly acidic water solution is the pH3-4 aqueous solution；
2) 5g~25g plant source antioxidant ingredients are dissolved in step 1) prepared by polysaccharide solution in；
Described plant source antioxidant is：It is one or more compound in Tea Polyphenols, phytic acid, vitamin C；
3) 25g~150g beeswaxs are heated to 60~80 DEG C, melt it, step 2 is then added under mechanical stirring)
In prepared polysaccharide solution, 0.5-12h is reacted, beeswax dispersion solution is obtained；
4) by step 3) prepared by beeswax dispersion solution be cooled to room temperature, that is, obtain based on beeswax aqueous dispersion
Coating antistaling agent.
The invention has the advantages that：
1st, selected materials safety is nontoxic, and course of reaction is simple, product overall safety, nontoxic；
2nd, the coating antistaling agent obtained is easy to film forming after drying, and film forming has certain water proofing property；With steady well
It is qualitative, at room temperature with flow regime；
3rd, there is preferable bacteriostatic activity.
The present invention is by beeswax liquefied, so that finished product is easier film or sprays to body surface to be dealt with, with
Traditional brushing beeswax is compared, and efficiency is improved；Product is used directly for the coating-film fresh-keeping of fresh agricultural products, and to satsuma orange
Effect is preferable.
