Abstract
The invention provides a kind of fruits and vegetables flower freshness bag, comprising: biological environmental production type natural disinfection mould inhibitor, ethylene inhibitor and auxiliary material.The present invention is one is novel environment friendly product, and good refreshing effect is applied widely, safe and harmless to human and environment.
Description
Technical field
The present invention relates to the fresh-keeping bag of a kind of fruit, vegetables and flower freshness.
Background technology
Mostly current antistaling agent is the function of fungus and mildew resistance and not anti-ethene, or only has anti-ethene not have antimycotic antiseptic effect, and has anti-ethene, has again a fungus and mildew resistance, and environment friendly preservation agent particularly also free from environmental pollution is still few.
Fruit, vegetables, the fresh-keeping of flowers comprise two aspects.First fungus and mildew resistance, it two is anti-ethene.At present, the antisepsis antistaling agent used in the storing of China fruit mainly contains carbendazim, probenazole, thiophanate-methyl, benomyl, imazalil, sec-butylamine, iprodione, sulfur dioxide etc. more than 20 and plants, but these anticorrisive agents all exist that valency is high, residual toxicity or the problem such as effect is bad.Find low toxicity, safe, efficient, easy to use and cheap vegetables and fruits flowers antisepsis antistaling agent, just seem important and urgent.
In order to environmental protection is avoided using chemical sterilization and mould inhibitor, use the fungus and mildew resistance product of plant origin instead.For example, cinnamic acid-Benexate Hydrochloride is sterilizing anticorrisive agent, particularly has remarkable result to fungi.To Escherichia coli, hay bacillus and golden yellow staphylococcus, staphylococcus albus, Shigella shigae, Typhoid and paratyphoid first bacillus, pneumococcus, aerobacteria, proteus, bacillus anthracis, Bacterium enteritidis, comma bacillus etc. have inhibitory action.And it is remarkable to gram-positive bacteria bactericidal effect.Nearest Japan medical science expert studies discovery, and cinnamic acid has obvious sterilizing effect to fungi.
Cinnamic acid has the advantages such as the low and aromatic odor of low toxicity, safety, cost, as a kind of safe natural source material, " state food safety standard food additives use standard " GB27602011 version is limitation to other antiseptic and fresh-keeping agent for fruits strict regulations, cinnamic acid is but just said " by producing required appropriate use " also namely have no restriction.In view of the above-mentioned advantage of cinnamic acid, its using method can be soaked fruit, fumigates and be adopted the flexibilities such as front spraying in addition, and expert pronounced cinnamic acid is expected into the most general fruit and vegetable preserving antistaling agent.
Mustard oil-Benexate Hydrochloride: it is the cyclodextrin inclusion compound of the total ester of the organic isothiocyanic acid of slow release, is used as flavor enhancement and bactericide in food.Because the sterilization component contained by mustard can kill the bacterium such as coliform, Staphylococcus aureus, and suppress the growth of mould and other toxic bacteria in food.Agriculturally can be used as biocide mildewcide.
Garlic oil-Benexate Hydrochloride: garlic is described as " natural broad-spectrum antibiotic ".The Main Ingredients and Appearance of garlic oil is: pi-allyl propyl disulfide compound, diallyl disulfide, diallyl trisulfide, allicin etc.Garlic oil antimicrbial power is strong, has the multiple fresh-keeping function of sterilization, mildew-resistant, expelling parasite.It has various pathogens such as soft rotten coccus, staphylococcus, Escherichia coli kills or inhibitory action.Garlic oil also has good bactericidal action to multiple fungi in addition.
Above-mentioned biocide mildewcide not only bactericidal mould proof effect is good, to people and environmental sound, and cuts and plays slow releasing function to volatile substances afterwards with cyclodextrin encapsulated, be convenient to preserve and use.
Fruits and vegetables flower antistaling agent is towards natural, nontoxic, environmental protection, efficient, multi-functional future development.What praised highly most is 1-methyl cyclopropene.1-methyl cyclopropene can block the combination of fruits and vegetables flowers Inner portion and external ethylene and fruits and vegetables flowers, reduces the activity of its breathing, rising Sum decomposition enzyme, delays senility, reach fresh-keeping object.Its consumption is extremely low in addition, be generally 1,000,000/, even part per billion, just can play fresh-keeping effect.It has efficient, nontoxic advantage.The preservation technique of current comparative maturity is stifling in fruits and vegetables depots.But fruits and vegetables will put process in storage, for fruits and vegetables in transit fresh-keeping very inconvenient, turn increase cost.For the ease of fruits and vegetables flowers transportation fresh-retaining, in tote box, Bian is the most convenient with fresh-keeping bag.
The fit applications of natural disinfection mould inhibitor and cyclopropylene is the most perfect environment-friendly type scheme.
