Abstract
The invention belongs to the technical field of preservation and fresh keeping of agricultural products such as fruits and vegetables and particularly relates to a natural fruit and vegetable sterilization fresh keeping agent containing a fructus corni extract and a use method of the natural fruit and vegetable sterilization fresh keeping agent. The natural fruit and vegetable sterilization fresh keeping agent comprises the following components in parts by mass: 0.1-80 parts of the fructus corni extract, 10-50 parts of a co-solvent, 0.1-5 parts of an antioxidant, 0.01-1 part of a surface active agent and 1000 parts of water. The natural fruit and vegetable sterilization fresh keeping agent provided by the invention takes natural substances in jujube fruits as main ingredients, has extremely-high food safety, cannot cause environmental pollution and has no health hazard to human bodies, an environmentally friendly, safe and natural fruit and vegetable postharvest enzyme-inhibiting anticorrosion and sterilization technology is provided, and the reuse and the residue of synthetic bactericides and chemical pesticides can be effectively reduced.
Description
Technical field
The invention belongs to storage and the technical field of preservation of fresh of fruits and vegetables agricultural product, particularly a kind of fructus corni extract natural fruit and vegetables antistaling disinfectant and using method thereof.
Background technology
China is traditional fruits and vegetables big producing country, and fruits and vegetables annual production is up to 900,000,000 tons.But because China's storage fruit and vegetable facility is not enough, postharvest handling is backward in technique, is difficult in time, carries out preservation and freshness to various fruits and vegetables in large quantities.Fruit and vegetable food moisture is high, and how ripe in summer, autumn high temperature season, is very easily subject to various infecting of pathogen and loss of rotting occurs after adopting.According to statistics, the annual postharvest fruit and vegetable loss late of China up to 25% ~ 30%, fruits and vegetables gathering, preserve, to transport and the rotten economic loss caused in process of consumption reaches 850 ~ 1,000 hundred million yuan, had a strong impact on supply and the consumption of fruit and vegetable food.At present, the main storage technique of fruits and vegetables has refrigeration, air control storage, chemical synthesis antistaling agent etc.Refrigeration is the most general preservation method, has a wide range of applications, but some fruits and vegetables easily damages to plants caused by sudden drop in temperature in cryopreservation process, occurs brown stain and quality deterioration.Air conditioned storage method due to invest huge, technical difficulty is high, management control overflow strict, energy consumption is huge, take the impact of the unfavorable factors such as resource is many, is still difficult to large-scale promotion application.Utilize chemical synthesis bactericide and agricultural chemicals effectively can control the postharvest disease of fruits and vegetables and loss of rotting, but long-term and a large amount of use synthesizing fungicide can make pathogen develop immunity to drugs and reduce diseases of garden stuff prevention effect, simultaneously residual synthesizing fungicide may produce harmful effect to the health of consumer and environment.Therefore, need natural, green, the non-harmful fruit vegetable postharvest disease of exploitation badly control and press down mould preservation technique.
Date fruit skin slag is often processed as processing waste, brings harmful effect to production environment.In fact, contain various plants secondary metabolite in fructus corni (slag) as polyphenol, Protoapigenone etc., chemical composition has catechin, epicatechin and coumaric acid etc. and the polymer based on these monomers.These naturally occurring botanical secondary metabolite have extremely strong biologically active in anti-oxidant, antibacterial, antiviral, anticancer change, prevention cardiovascular and cerebrovascular disease etc., obtain increasing research and apply in fields such as agricultural production, food processing, health care, development of functional food.Although date fruit (fructus corni) polyphenol substance extraction and isolation and anti-oxidation function thereof are studied and are reported, the report that there is not yet fructus corni (slag) extract bacteriostasis and apply on the antibacterial anti-corrosive fresh-keeping of fruits and vegetables.
Summary of the invention
The object of the invention is to propose a kind of fructus corni extract natural fruit and vegetables antistaling disinfectant, it has green, safe, natural postharvest fruit and vegetable presses down the anticorrosion and sterilization fresh-keeping technology of enzyme, can effectively reduce synthesizing fungicide and chemical pesticide using and residual.
Another object of the present invention is the using method proposing a kind of natural fruit and vegetables antistaling disinfectant.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of fructus corni extract natural fruit and vegetables antistaling disinfectant, is characterized in that:
