Abstract

The present invention is a kind of fresh-maintaining agent with function membrance using natural drying method.Protective finish as melon and fruit, vegetables, Fresh preservation for fowl eggs.Contain filmogen in this antistaling agent, this filmogen tack is good, in coating by the aqueous mutual adhesion of coating that becomes fresh-keeping thing when solid-state, can natural air drying, simplified the operation of using antistaling agent.Film has selection function to moisture and gas, can discharge the carbon dioxide that produces in the fresh-keeping thing, and gases such as ethene prevent that oxygen from immersing, and keep moisture, make fresh-keeping thing keep fresh and tender.

Description

Fresh-maintaining agent with function membrance using natural drying method
The present invention is a kind of immersion coating agent that is used for melon and fruit, vegetables, Fresh preservation for fowl eggs.
At present, the antistaling agent that is used for dip-coating fruit, vegetable surface roughly has two classes.One class is the non-water-soluble coating agent, as coatings such as paraffin, has played secluding air, keeps the effect of melon and fruit internal moisture.Another kind of is to use starchy carbohydrate, and pastel is made in Chinese herbal medicine etc. and artificial synthetic macromolecular material agent, and add the sterilization detoxicating and medicament fresh-keeping to realize.Use these antistaling agents must be furnished with special coating machine, the equipment of hot blast drying to avoid viscous coating not solidifying the anterior synechiae damage fully, makes coating evenly cover fruit surface all sidedly.Particularly when fresh-keeping, later on also will to melon and fruit surface carry out polishing at wax spray with waxing, these methods not only one-time investment takes height, and the size and the hardness of fruit is had certain requirement.And, a considerable amount of loss lates are generally all arranged.
It is easy with dip-coating to the objective of the invention is to propose a kind of manufacturing, the antistaling agent with low cost of free of losses rate.
Principle of the present invention is to be coated with the selective ventilative functional membrane of last layer on the surface of fresh-keeping thing.This functional membrane can stop that most oxygen enters fruit inside in the air, allows gases such as inner carbon dioxide that produces of melon and fruit and ethene freely to see through again.The film surface has the hydrophobic group outside, repels airborne moisture, stops vegetative effect.Characteristics of the present invention be when the antistaling agent dip-coating behind fresh-keeping thing surface, even be under the wet condition, the preservative film of each fresh-keeping thing can inter-adhesively not torn yet, each fresh-keeping beyond the region of objective existence surface by dip-coating can both form topped complete preservative film behind natural air drying, thereby it is fresh-keeping to avoid using complicated optional equipment to use antistaling agent to realize.Saving of labor, material-saving have been saved cost of equipment again like this.
The manufacture method of fresh-maintaining agent with function membrance using natural drying method of the present invention be such as: in the aqueous solution of the water soluble polymer that carboxymethyl cellulose, water soluble cellulose acetate, polyvinyl alcohol, silanol etc. are nontoxic, interpolation such as pore formers such as citric acid, polyvinyl alcohol, acetic acid, boric acid, phosphoric acid, with such as surfactants such as tween, polyethylene glycol oxides, and such as anticorrisive agents such as sorbic acid, honey, vinegars, above-mentioned substance is dissolved in the water at 20 ℃-90 ℃, stirred 5-120 minute, and promptly got transparent rare dope of indication of the present invention.
When using this antistaling agent, must remove the fresh-keeping thing that has rotted in advance.Deposit to melon and fruit is fresh-keeping, behind the surplus bacterium of detoxicating, will be immersed antistaling agent 0.1-60 minute by fresh-keeping thing integral body as usual, the whole taking-up, and natural airing can be packed deposit.Also habitual detoxicating bactericide can be sneaked into antistaling agent, once flood air-dry then packing.
At room temperature freshness-retained 20～180 days of the freshness date of the handled melon and fruit of this antistaling agent, birds, beasts and eggs, weight-loss ratio 1～10%.
The prescription of antistaling agent is (percentage by weight):
One
Carboxymethyl cellulose 1～5%
Citric acid 0.1～0.5%
