Description
Technical field
The present invention relates to a kind of aqueous vapor isolated form nanometer ethylene absorbent, belong to processing of farm products storage technique field.
Background technology
, due to being influenceed by factors such as physics, physiology and pathology after adopting, its yield and quality are all for water fruits and vegetables and flowers
Lost by serious.Shown according to FAO statistics, in the world developed country due to postharvest fruit and vegetable preservation technique it is fairly perfect,
Its product loss late is only 5%, and developing country is 20% one 30%, and China's postharvest fruit and vegetable loss is 20% or so.Hua Qibao
Fresh is also highly important work in commercial floriculture production, storing and circulation.
Ethene is the eubolism product of plant cell, as a kind of endogenous hormones of plant, plant physiology process is risen
Many regulating and controlling effects.Ethene a large amount of synthesis before fruits and vegetables are ripe, with promoting fruits and vegetables maturation, but after the adopting of fruits and vegetables
During storage, ethene can produce some detrimental effects, including promote aging, promote maturation and soften, aggravate mass loss, make
Fruit easily by pathogenic bacterial infection and cause physiologic derangement etc. other aspect.In postharvest fruit and vegetable storage, except fruits and vegetables itself are produced
Endogenous ethylene outside, also have from food chain, packaging, storage, in transit with freezer in exogenous ethylene, such as machinery damage
Consumption, pollution and the metabolism of plant and fungi.Therefore, postharvest fruit and vegetable avoids the movable necessary of ethene.
In recent years, the methods for occurring in that many control postharvest fruit and vegetable ethene, conventional reduction or eliminate ethene method it
One is to use ethylene absorbent, or ethene is prevented using ethylene inhibitor to the detrimental effect of fruits and vegetables.At present, ethene suppresses
Agent application it is more be l-methyl cyclopropene class (1-MCP), it is combined by with ethylene receptor, so that the product of ethene suppressing
It is raw, although to have positive effect to most of climacteric type fruits and vegetables with l-MCP treatment, but can also produce or disturb one
The normal ripening and senscence of a little fruits and vegetables, meanwhile, l-MCP costs are too high, and fruits and vegetables dealer be rarely employed.The country is in ethylene absorbent
And production method aspect has more patent, such as a kind of ethylene absorbent and preparation method thereof（Application No.：
200910086958.6, applicant China Agricultural University）, improved copper ethylene absorbent and preparation method thereof（Application number：
CN200910096222.7, applicant:Zhejiang University）, a kind of production technology of ethylene absorbent (application number CN20111,
0262617), ethylene absorbent preparation method (application number CN201110283136).But existing ethylene absorbent has as follows
Shortcoming：(1) oxidation Decomposition type ethylene absorbent, the general oxidation Decomposition type with potassium permanganate as representative for using at present, such
Although type use time is long but there is the shortcomings of removal rate is slow, not water-fast, fresh-keeping effect is not obvious.(2) absorbent-type ethene
Absorbent, the general absorbent-type with activated carbon as representative for using at present, although the type clearance is high, after adsorption saturation i.e.
Failure, or even also have the danger of desorption.Therefore ethylene absorbent active constituent content and absorption efficiency how are improved, to reducing garden
Skill product rots, loss, and enhancing fruits and vegetables, fresh-keeping effect of flowers etc. have positive meaning.
The content of the invention
It is an object of the invention to provide a kind of aqueous vapor isolated form nanometer ethylene absorbent, the ethylene absorbent and conventional leech
Stone, activated carbon ethylene absorbent are compared, with small volume, efficiency high, the advantages of long lifespan.
The object of the present invention is achieved like this：A kind of aqueous vapor isolated form nanometer ethylene absorbent, it is characterised in that by with
Lower multilayer material is constituted：Nanometer ethylene absorption particle, ventilating water proof type macromolecule membrane, absorbent material particle, outside thin porous layer
Packaging material.
The preparation technology of wherein described nanometer ethylene absorption material is：It is 1 to add volume ratio using Nano carbon white:1-
1:3 saturation liquor potassic permanganate, boils 5-10 minutes, cooling, filtering, is formed in drying at 60 DEG C.
Described ventilating water proof type macromolecule membrane comprising can resist potassium permanganate oxidation, pore size can by steam,
But the thin-film material of impermeable water droplet.
The chemical bond mould assembly absorbent material constituted as 1-5 parts of described absorbent material particle, 0.5-2 parts of calcium chloride,
Calcium oxide or hydroscopic high-molecular resin are mixed.
Described thin porous layer housing material is the perforated nonwoven fabrics of water-fast stretch-proof type, composite fibre paper.
The combination of described above multilayer material is：Ground floor be thin porous layer housing material as outermost layer,
The second layer be absorbent material hybrid particle, third layer ventilating water proof type macromolecule membrane, the 4th layer be nanometer ethylene absorption material
Material, layer 5 is back cover layer.
The present invention produce good effect be：
1st, a kind of aqueous vapor isolated form nanometer ethylene absorbent of the invention, the Nano carbon white material for using expands absorbing surface
Product, greatly improves absorption rate, while being isolated ethylene absorbent and absorbent material using macromolecular material, it is to avoid second
Steam in the steam, the environment that are produced in alkene absorption process causes the failure of ethene vapor and efficiency to decline.
2nd, the hydroscopic high-molecular resin in composite absorbent material layer, the water that 600 times of absorbent own vol is prevented effectively from
Fruits and vegetables respiration ponding causes the defect of medicament dissolution polluted product, and ethylene absorbent of the invention efficiently can quickly absorb
Ethylene gas, compare with conventional vermiculite, activated carbon ethylene absorbent, with small volume, efficiency high, the advantages of long lifespan.
3rd, a kind of aqueous vapor isolated form nanometer ethylene absorbent of the invention is of good preservation effect, can make fresh water fruits and vegetables and
