Abstract
The invention discloses a water vapor separation type nano ethylene absorbent for the technique of agricultural product processing and storage. A porous thin layer machine is used as a first layer, a composite water absorption material is used as a second layer, a breathable waterproof type polymer thin film is used as a third layer, a nano ethylene absorbent is used as a fourth layer and a sealing layer is used as the bottom layer. The absorbent has the advantages that due to use of nano white carbon black material, the absorption area is enlarged and the absorption speed is greatly improved; meanwhile, the ethylene absorbent and the water absorption material are separated by a polymer material, the problem that the ethylene absorbent loses efficacy and the efficiency drops due to the ambient water vapor and water vapor generated during ethylene absorption is avoided; as the polymer water absorption resin in the composite water absorption material layer is capable of absorbing water the volume of which is 600 times that of the resin self, the defect that the agent is dissolved and the product is contaminated due to the breath action of fruit and vegetables and water accumulation is effectively avoided; compared with a normal vermiculite and an active ethylene absorbent, the nano ethylene absorbent has the characteristic of small volume, high efficiency and long service life and is particularly suitable for fresh product e-business having high requirements on weight and volume.
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
Fruit, vegetables and flowers are due to the impact by factors such as physics, physiology and pathology after adopting, and its seed output and quality is all subject to serious loss.According to the display of FAO statistics, in the world developed country due to postharvest fruit and vegetable preservation technique fairly perfect, its product loss rate is only 5%, and developing country is 20% one 30%, and China's postharvest fruit and vegetable is lost in about 20%.Hua Qi is fresh-keeping is also very 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, plays many-sided regulating and controlling effect to plant physiology process.Ethene synthesizes in a large number before fruits and vegetables maturation, have and promote that fruits and vegetables are ripe, but when the postharvest storage of fruits and vegetables, ethene can produce some adverse influences, comprises and promotes aging, promotion maturation and soften, aggravate mass loss, make fruit be subject to pathogenic bacterial infection and cause other aspects such as physiologic derangement.In postharvest fruit and vegetable storage, except the endogenous ethylene that fruits and vegetables self produce, also have from food chain, packaging, storage, in transit with the exogenous ethylene in freezer, such as mechanical loss, pollute and the metabolism of plant and fungi.Therefore, postharvest fruit and vegetable avoids the activity of ethene necessary.
In recent years, occurred the method for a lot of control postharvest fruit and vegetable ethene, one of conventional reduction or the method eliminating ethene for adopting ethylene absorbent, or adopt ethylene inhibitor to stop ethene to the detrimental effect of fruits and vegetables.At present, what ethylene inhibitor application was more is l-methyl cyclopropene class (1-MCP), it is by being combined with ethylene receptor, thus the generation of ethene suppressing, although positive effect can be had to most of climacteric type fruits and vegetables with l-MCP process, also can produce or disturb the normal ripening and senscence of some fruits and vegetables, simultaneously, l-MCP cost is too high, and fruits and vegetables dealer seldom use.Domestic have more patent in ethylene absorbent and production method, as a kind of ethylene absorbent and preparation method thereof, (application number is: 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 (application number CN20111,0262617) of ethylene absorbent, ethylene absorbent preparation method (application number CN201110283136).But existing ethylene absorbent has following shortcoming: (1) oxidation Decomposition type ethylene absorbent, current use general take potassium permanganate as the oxidation Decomposition type of representative, although the type service time long exist removing speed slowly, the shortcoming such as not water-fast, fresh-keeping effect is not obvious.(2) absorbent-type ethylene absorbent, use at present general take active carbon as the absorbent-type of representative, although the type clearance is high, adsorb saturated after namely lost efficacy, even also have the danger of desorption.Therefore how to improve ethylene absorbent active constituent content and absorption efficiency, loss rotten to minimizing gardening product, the fresh-keeping effect etc. of enhancing fruits and vegetables, flowers has positive meaning.
Summary of the invention
The advantages such as the object of this invention is to provide a kind of aqueous vapor isolated form nanometer ethylene absorbent, this ethylene absorbent is compared with conventional vermiculite, active carbon ethylene absorbent, and have volume little, efficiency is high, and the life-span is long.
The object of the present invention is achieved like this: a kind of aqueous vapor isolated form nanometer ethylene absorbent, is characterized in that, be made up of following multilayer material: nanometer ethylene absorption particle, ventilating water proof type macromolecule membrane, absorbent material particle, thin porous layer housing material.
The preparation technology of wherein said nanometer ethylene absorption material is: use Nano carbon white to add the saturated liquor potassic permanganate that volume ratio is 1:1-1:3, boil 5-10 minute, cooling, filter, at 60 DEG C, drying forms.
Described ventilating water proof type macromolecule membrane comprises and can resist potassium permanganate oxidation, and pore size by steam, but can not permeate the thin-film material of water droplet.
The chemical bond mould assembly absorbent material consisting of 1-5 part of described absorbent material particle, the calcium chloride of 0.5-2 part, calcium oxide or hydroscopic high-molecular resin mix.
Described thin porous layer housing material is perforated nonwoven fabrics, the composite fibre paper of water-fast stretch-proof type.
The combination of described above multilayer material is: ground floor is that thin porous layer housing material is as outermost layer, the second layer is absorbent material hybrid particle, third layer ventilating water proof type macromolecule membrane, the 4th layer is nanometer ethylene absorption material, and layer 5 is back cover layer.
The good effect that the present invention produces is:
1, a kind of aqueous vapor isolated form of the present invention nanometer ethylene absorbent, the Nano carbon white material used expands absorption area, greatly improve absorption rate, use macromolecular material by ethylene absorbent and absorbent material isolation simultaneously, avoid the steam, the steam in environment that produce in ethylene absorption process and cause the inefficacy of ethene vapor and efficiency to decline.
2, the hydroscopic high-molecular resin in composite absorbent material layer, the water of absorbent own vol 600 times, fruits and vegetables respiration ponding is effectively avoided to cause the defect of medicament dissolution polluted product, ethylene absorbent of the present invention efficiently can absorb ethylene gas fast, compare with conventional vermiculite, active carbon ethylene absorbent, the advantages such as have volume little, efficiency is high, and the life-span is long.
3, the good refreshing effect of a kind of aqueous vapor isolated form of the present invention nanometer ethylene absorbent, extend during making the storing of fresh fruit, vegetables and flowers, extensively be suitable for various fruits and vegetables and flowers product and preservation, be specially adapted to weight, the fresh electric business that volume has higher requirements uses.
