The present invention relates to a kind of fruit and vegetable fresh-keeping agent containing oligochitosan, effective ingredient is grouped into by the one-tenth of following weight ratio: oligochitosan 1.0 5.0%, Folium Menthae extract 1.0 2.5%, and the weight ratio of oligochitosan and Folium Menthae extract is 1 5:1 2.The fruit and vegetable fresh-keeping agent of the present invention is environmentally friendly, harmless to human non-toxic, has good fresh-keeping effect to fruit and vegerable.
Description
Technical field
The present invention relates to postharvest technology of fruits and vegetables field, be specifically related to a kind of fruit and vegetable fresh-keeping agent containing oligochitosan.
Background technology
Fresh fruit of vegetables is the requirement that people live, in good time, rapidly, high-quality fresh water fruits and vegetables from grown place fortune
Toward area of consumption, it is possible not only to link up urban and rural economies contact in time, expands market for commodities, activate rural economy, promote agricultural development,
And urbanite can be better met again to food increasing need.But fresh fruit of vegetables still carries out multiple after gathering
Miscellaneous physiological change, the cell of fruit and vegerable and tissue proceed breathe and transpiration, it is easy to produce shrinkage, weightlessness, wilting,
The phenomenon such as rot, rotten, affect quality and the sale of fruit and vegerable.Therefore, preserving fruit and vegetable utilizing is that vegetable and fruit produces, stores and sell ring
A very important problem in joint.
Current fruit and vegetable fresh-keeping agent is substantially based on chemical preservative, and the organic bactericide in chemical preservative and anticorrosion
Agent can remain at fruit and vegerable epidermis, toxic to human body.Under the overall situation that food safety is the most concerned, the antistaling agent of safety and environmental protection
Enjoy favor.Chitosan is as a kind of edible natural Perserving materials, owing to having preferable film property, gas selective penetrated property
And antibiotic property, it is widely used in the research of preserving fruit and vegetable utilizing.
Herba Menthae is the aerial parts of Labiatae perennial root herbaceous plant Mentha, and Folium Menthae extract has antioxidation
Property, eliminate free radical, the lipid peroxidation of suppression hydroxy radical induction, protection biofilm structure and function, have simultaneously
Antibacterial, biocidal efficacies.
Relevant report is yet there are no as the fruit and vegetable fresh-keeping agent of main component at present using oligochitosan, Folium Menthae extract mixture.
Summary of the invention
It is an object of the invention to, for chemical preservative, there is pollution environment, harmful shortcoming, it is provided that a kind of right
Environmental friendliness, to human non-toxic harmless containing oligochitosan fruit and vegetable fresh-keeping agent.
The present invention adopts the technical scheme that: a kind of fruit and vegetable fresh-keeping agent containing oligochitosan, and effective ingredient is by following weight hundred
The one-tenth of proportion by subtraction is grouped into: oligochitosan 1.0-5.0%, Folium Menthae extract 1.0-2.5%, and surplus is that water complements to 100%.
Described oligochitosan and the weight ratio of Folium Menthae extract are 1-5:1-2, preferred oligochitosan and Folium Menthae extract
Weight ratio is 5:2.
Described Folium Menthae extract is according to made by the following step:
(1) dried Herba Menthae powder is broken to 60-200 mesh, obtains Herba Menthae powder.
(2) it is that 1:10 is separately added into Herba Menthae powder and distilled water according to solid-liquid ratio, is heated to reflux 4h, filtration, extract secondary, close
And filtrate, the concentrated solution concentrated with Rotary Evaporators, lyophilization concentrated solution, obtain Folium Menthae extract.
The preparation method of the described fruit and vegetable fresh-keeping agent containing oligochitosan can use the mixing method of routine, and its solution can be adopted
With conventional dissolving method.I.e. according to formula proportion precise oligochitosan, Folium Menthae extract, water, stir and make to mix
Compound fully dissolves and i.e. obtains a kind of fruit and vegetable fresh-keeping agent containing oligochitosan.
The using method of the described fruit and vegetable fresh-keeping agent containing oligochitosan is: by antistaling agent dilute with water 50-200 times, afterwards
Fresh fruit of vegetables is directly soaked 3-5min in diluent, or diluent is sprayed, is coated in fruit and vegetable surfaces, naturally dry, store guarantor afterwards
Deposit.
The present invention has the following advantages and notable technique effect: each component in the present invention has well played collaborative effect
Should, wherein oligochitosan has film property, it is possible to form transparent protecting film at fruit and vegetable surfaces, limits fruit and vegerable and extraneous oxygen and two
The gas exchange of carbonoxide, film inner silica concentration of carbon is high, reduces fruit and vegerable respiratory intensity and acetate releasing quantity.Meanwhile, this guarantor
Cuticula can also stop moisture to evaporate, and prevents microbial infection, thus effectively extends the freshness date of fruit and vegerable.Folium Menthae extract is permissible
Play bactericidal action, well inhibit the growth of microorganism, extend the freshness date of fruit and vegerable.Oligochitosan and the group of Folium Menthae extract
Close and make the fruit and vegetable fresh-keeping agent of the present invention have good fresh-keeping effect in the range of weight proportion.
Detailed description of the invention
Below in conjunction with embodiment, technical scheme and beneficial effect are described further, of the present invention hundred
Proportion by subtraction is all weight percentage.
