Description
Technical field
The invention belongs to the storage of fruits and vegetables agricultural product and technical field of preservation of fresh, more particularly to a kind of fructus corni extract natural fruit
Vegetable antistaling disinfectant and its application method.
Background technology
China is traditional fruits and vegetables big producer, and fruits and vegetables annual production is up to 900,000,000 tons.However, because China's fruit vegetables storing is protected
Fresh facility is not enough, and postharvest handling is backward in technique, it is difficult to carry out preservation and freshness to various fruits and vegetables in time, in large quantities.Fruit and vegetable food water
Divide content high, and many maturations are highly prone to various infecting for pathogen and occur rotten loss in summer, autumn high temperature season after adopting.
According to statistics, the annual postharvest fruit and vegetable loss late of China is up to 25%~30%, and fruits and vegetables are in harvesting, storage, transport and process of consumption
The rotten economic loss caused up to 850~100,000,000,000 yuan, had a strong impact on the supply and consumption of fruit and vegetable food.At present, fruits and vegetables
Main storage technique has refrigeration, air control storage, chemical synthesis antistaling agent etc..Refrigeration is most common fresh-keeping side
Method, has a wide range of applications, still, and some fruits and vegetables easily damage to plants caused by sudden drop in temperature during cryopreservation, brown stain and bad quality occur
Become.Air conditioned storage method is due to investing that huge, technical difficulty is high, management control requires that strict, energy consumption is huge, take resource more than etc.
The influence of unfavorable factor, is still difficult to large-scale promotion application.Fruits and vegetables can be effectively controlled using chemical synthesis bactericide and agricultural chemicals
Postharvest disease and loss of rotting, it is but long-term and a large amount of pathogen can be made to develop immunity to drugs using synthesizing fungicide and reduce fruit
Vegetable disease-controlling effect, while the synthesizing fungicide of residual may produce harmful effect to the health and environment of consumer.Therefore,
Need natural, green exploitation, non-harmful fruit vegetable postharvest disease control badly and press down mould preservation technology.
Date fruit skin slag is often disposed off as processing waste, and harmful effect is brought to production environment.In fact,
Contain various plants secondary metabolite such as polyphenol, Protoapigenone etc. in fructus corni (slag), chemical composition has catechin, epicatechin
With coumaric acid etc. and the polymer based on these monomers.The botanical secondary metabolite of these naturally occurring is in anti-oxidant, suppression
Bacterium, antiviral, anticancer become, prevent have extremely strong bioactivity in terms of cardiovascular and cerebrovascular disease, add in agricultural production, food
The fields such as work, health care, development of functional food have obtained increasing research and application.Although date fruit (fructus corni) polyphenol
Material extract separation and its anti-oxidation function studied and reported, but there is not yet fructus corni (slag) extract bacteriostasis and its
The report applied on the antibacterial anti-corrosive fresh-keeping of fruits and vegetables.
The content of the invention
The purpose of the present invention is to propose to a kind of fructus corni extract natural fruit and vegetables antistaling disinfectant, it has green, safety, day
Right postharvest fruit and vegetable suppression enzyme anti-corrosion and sterilization fresh-keeping technology, can effectively reduce the use of synthesizing fungicide and chemical pesticide and residual
Stay.
It is another object of the present invention to propose a kind of application method of natural fruit and vegetables antistaling disinfectant.
To achieve the above object, technical scheme is as follows：
A kind of fructus corni extract natural fruit and vegetables antistaling disinfectant, it is characterised in that：
The antistaling agent includes fructus corni extract, cosolvent, antioxidant, surfactant and water, and its composition and ratio (is pressed
Quality parts ratio) be：Fructus corni extract 0.1~80, cosolvent 10~50, antioxidant 0.1~5, surfactant 0.01~
1st, water 1000.
The composition and ratio (by quality parts ratio) of the antistaling agent is：Fructus corni extract 0.5, cosolvent 20, antioxidant
0.1st, surfactant 0.1, water 1000.
The cosolvent is selected from one or both of methanol, ethanol, propyl alcohol, isopropanol and two or more mixtures.
The antioxidant is one kind or two in ascorbic acid, sodium ascorbate, arabo-ascorbic acid, sodium isoascorbate
Plant and two or more mixtures.
The surfactant is polyoxyethylene (20) sorbitanmonolaureate, polyoxyethylene (20) sorbitol anhydride list
One kind in palmitate, polyoxyethylene (20) sorbitan monostearate, polyoxyethylene (20) sorbitan mono-oleic acid ester
Or two kinds and two or more mixtures.
The surfactant is polyoxyethylene (20) sorbitanmonolaureate.
Fruits and vegetables are immersed in the natural fruit and vegetables and killed by a kind of application method of fructus corni extract natural fruit and vegetables antistaling disinfectant
2~30min in bacterium antistaling agent, pulls out and dries, and carries out preservation and freshness.
The beneficial effects of the present invention are：
Fructus corni extract natural fruit and vegetables antistaling disinfectant involved in the present invention can effectively suppress by pathogen infection
Caused fruit and vegetable food postharvest disease, significantly decreases postharvest fruit and vegetable and rots to lose and quality decline.
Fructus corni extract natural fruit and vegetables antistaling disinfectant main component involved in the present invention is the natural goods in date fruit
Matter, with high foodsafety, environmental pollution is not caused, there is provided green, safe, natural without health hazard to human body
Postharvest fruit and vegetable suppression enzyme anti-corrosion and sterilization fresh-keeping technology, can effectively reduce the use of synthesizing fungicide and chemical pesticide and residual
Stay.
Fructus corni extract natural fruit and vegetables antistaling disinfectant involved in the present invention takes full advantage of date fruit skin slag and processing
The accessory substances such as leftover bits and pieces, with apply easy, easy to spread, small investment instant effect, cheap, extensive market, using safety,
The advantages of economic benefit and notable social benefit, there are very big development and application values.
