Description
Technical field
The utility model belongs to the postharvest technology of fruits and vegetables field, relates to a kind of preserving fruit and vegetable utilizing cartridge bag.
Background technology
Ethylene gas is a kind of modal plant hormone, and it can cause the overdone and putrid and deteriorated of fruit, vegetables.Fruits and vegetables self discharges is endogenous ethylene, and what come from the outside is called exogenous ethylene, thereby the ethene of these two kinds of approach generations can both be combined with the ethylene receptor site of fruits and vegetables and be caused the overdone and rotten of them.
1-methyl cyclopropene (1-MCP) is a kind of ethene blocking agent of highly effective and safe, it can preferentially irreversibly be combined with the ethylene receptor site of fruits and vegetables, its binding ability is 10 times of ethene, can block efficiently endogenous and exogenous ethylene, thereby is widely used in the fresh-keeping of fruits and vegetables.
1-MCP often carries out under the large space environment such as freezer the Preservation Treatment of fruits and vegetables at present, basic step is at first calculating the amount of the 1-MCP of needs according to the spatial volume of freezer, then in freezer, load weighted 1-MCP/ alpha-cyclodextrin complex compound joined to stir in the buffer fluid and discharge, closed processes some hours again after discharging fully, world patent WO0143548 describes relevant details in detail with US Patent No. 2002058592, US2002061822 etc.But this processing mode exists shortcomings, at first troublesome poeration needs before the use to calculate in detail, also needs equipment, medicament and the technical ability of specialty during processing, more than operation often can only be undertaken by specific technical personnel, and this has limited being widely used of 1-MCP greatly; Secondly there is certain risk in this mode that focuses on, if because of the misoperation of technical personnel or bring objectionable impurities into by other approach and then may cause the fruits and vegetables in the whole freezer to degenerate; This processing mode of fruits and vegetables of again carrying out Preservation Treatment for the rear urgent need of harvesting often has hysteresis quality, can cause a large amount of fruits and vegetables to degenerate; The 4th, because the space is excessive, there is the inhomogeneous problem of processing in this fresh-keeping mode; Described at Chinese patent CN102440237 such as us in addition, this 1-MCP/ alpha-cyclodextrin complex compound complex manufacturing and expensive, using method are also professional.
Compared with the mode that in freezer, focuses on, at present the fruits and vegetables industry more need a kind ofly can to process on a small scale, easy to operate, cheap 1-MCP medicament, can be behind fruit and vegetable picking deposit, transport or the link such as sale by orchard worker or retailer in the compartment or the less space such as fruit case fresh-keeping by oneself.
US Patent No. 6426319 has been described a kind of prescription, it is comprised of 1-MCP/ alpha-cyclodextrin complex compound, dextrin and hygroscopic agent, be positioned over during use in the air of certain humidity and discharge, the prescription that this patent is described seems to make the parcel with preservation, the aqueous vapor that places the fresh-keeping vegetable and fruit packaging bag of wish to rely on the fruits and vegetables respiration to produce can discharge 1-MCP, but shows that practicality is little after experiment.At first this fresh-keeping composition is expensive, and according to the ratio in this patent example 1, the weight ratio of 1-MCP/ alpha-cyclodextrin in prescription is 25%; Secondly because the complex compound solubility of the alpha-cyclodextrin of 1-MCP is less, make its decomplexing merging discharge 1-MCP and often need a large amount of aqueous waters, the water that needs 5 times of complex compound weight of describing such as Chinese patent CN1457636 discharges, but under continuous stirring, also only discharged 43% after 5.5 hours, for making release need in water, add soda acid fully or passing into carbon dioxide, therefore the prescription among the US6426319 only relies on the aqueous vapor in the absorbing air to be difficult to discharge fully, and form the larger solution of viscosity behind the hygroscopic agent deliquescence such as calcium chloride, so that the dissolving of complex compound and air release are more difficult.
US Patent No. 6770600 has been described a kind of paster that can discharge 1-MCP gas, and it is comprised of A and B two parts.Wherein A is the part that produces 1-MCP gas, and method for making is for forming certain thickness pressure layer with being pressed onto after 1-MCP/ alpha-cyclodextrin complex compound, sodium bicarbonate, polyvinylpyrrolidone and mixing such as adhesives such as carboxymethyl cellulose on filter paper or the polymer thin film with holes; B partly is release portion, and method for making evenly is applied to the dry rear certain thickness coating that forms on the polyethylene film with scraper after cellulose, citric acid etc. being dissolved in the liquid that forms certain viscosity in the water.When fresh-keeping A part and B are partly fitted, discharge 1-MCP gas under the effect of aqueous vapor, wherein the carbon dioxide of the citric acid reactions generation of the sodium bicarbonate of A part and B part can promote the release of 1-MCP.Although the utility model person of this paster claims this paster and is applicable to the preserving fruit and vegetable utilizing of inner wrapping, but apparent this paster production and use are complicated, cost is higher, and 1-MCP/ alpha-cyclodextrin complex compound might part release and cause inefficacy when make pressing layer.Chinese patent CN1692723 improves this paster; method for making is that 1-MCP/ alpha-cyclodextrin complex compound, D-sorbite, acetyl tributyl citrate, cellulose, acetone are spread upon on the paper; all the other compositions form coating, the 1-MCP that this scraps of paper can discharge more than 90% in 4 hours after the acetone volatilization in 100% relative humidity.No longer need to make respectively A, B part although this coating is compared with US6770600, use procedure is also simpler, and this class technical costs of radical change is not high for this scraps of paper, the shortcoming of production process complexity.
Chinese patent CN1371603 has described a kind of packing, and its method for making is for to be hot melt to 1-MCP/ alpha-cyclodextrin complex compound in the films such as polyvinyl alcohol film, high density polyethylene (HDPE), and this film can discharge 1-MCP gas under certain humidity.Although the purpose of this patent is the packing that have preservation in order to develop, this film still has complex manufacturing, shortcoming with high costs.
Chinese patent CN1907046A, CN1927002A have reported that the 1-MCP gas that will generate absorbs with organic solvent, make the method for fresh-keeping liquid or spray behind the adding polymerization inhibitor, organic solvent comprises propylene glycol, ethanol, isopropyl alcohol, pentaerythrite etc., polymerization inhibitor is p methoxy phenol, 2,4,6-tri-butyl-phenols etc. directly drip or are sprayed to fruit and vegetable surfaces with fresh-keeping liquid during use.Although above utility model is claimed 1-MCP and can be existed more than 12 weeks by ambient stable, but because 1-MCP still can produce mutually collision between such molecules in solution, in fact the polymerization speed of 1-MCP in above solution is faster, and a significant feature is to occur white cotton-shaped poly-mer behind the certain hour in the solution; For avoiding polymerization, this solution will be kept under the environment of relative low temperature, and the words of long-distance transport then need freezing preservation, and this has brought very large difficulty all for the use of this solution and aerosol.The more important thing is that polymerization inhibitor is poisonous aldehydes matter because absorbent is organic solvent, these organic solvents or phenolic compound exist grave danger to the health of human body.The existence of organic solvent and phenolic inhibitor is also harmful to vegetables, fruit, flowers, can cause that their acceleration is corrupt and rotten, and this obviously runs counter to wanting fresh-keeping purpose.
Chinese patent CN102217671A has described a kind of method for making of 1-MCP microcapsules, and its process is 1-MCP gas to be passed in the clad materials such as gelatin or High molecular material form microcapsules, thereby has the effect of slowly-releasing.But be not separated from each other owing to be wrapped between the 1-MCP gas molecule in the microcapsules, thereby still can lose efficacy by polymerization reaction take place between them, therefore yet Practical significance useless of this microcapsules.
Therefore the fruits and vegetables industry be badly in need of a kind of with low cost, safe preservation device simple to operate, and can carry out easily Preservation Treatment to the fruits and vegetables of inner wrapping.

Description of drawings
Fig. 1 is structural representation of the present utility model;
Wherein: 1 is the outsourcing box body; 2 is inner lining bag; 3 is fresh-keeping regent pack.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done to describe in further detail, described is to explanation of the present utility model rather than restriction.
Referring to Fig. 1, a kind of preserving fruit and vegetable utilizing cartridge bag comprises outsourcing box body 1, is provided with inner lining bag 2 in the outsourcing box body 1, is provided with fresh-keeping regent pack 3 in the inner lining bag 2; Described fresh-keeping regent pack 3 comprises wrapper, is provided with the absorption carrier that absorption has the 1-methyl cyclopropene in the wrapper, and fresh-keeping regent pack discharges the 1-methyl cyclopropene after absorbing moisture.
For the ease of the convenience of miniaturization and use, especially can be fresh-keeping to fruits and vegetables of when transportation, so not only avoid too much carrying but also can save time and avoid the consumption of fruits and vegetables; So preferred, discharge the 1-methyl cyclopropene behind the moisture that the wrapper of fresh-keeping regent pack and absorption carrier absorption fruits and vegetables respiration produce.
Wrapper and the absorption carrier to fresh-keeping regent pack of lower mask body describe respectively.
Because wrapper is the outermost layer that contacts with fruits and vegetables, breathe the moisture that produces so should see through fruits and vegetables, also to appear on the other hand the 1-methyl cyclopropene that discharges, so described wrapper is the wrapper that is provided with breather hole.
Concrete, described wrapper is heat-sealing filter paper, extrusion coating paper, nonwoven fabrics, complex film, reticulate pattern paper or Du Pont's paper, and these materials all have certain intensity and have good permeability to air, and moisture and 1-MCP gas all are easier to penetrate, and be convenient to packing, sorbing material is divided dissipate.
It is the key that fresh-keeping regent pack can discharge the 1-methyl cyclopropene that absorption has the absorption carrier of 1-methyl cyclopropene.
Absorption carrier need to be chosen as the aerated materials with high-ratio surface that surface distribution has hole, and described aerated materials includes but not limited to the compound of wherein one or more such as silica gel, active carbon, diatom earth, molecular sieve, atlapulgite, zeolite.
Comparing aerated materials with alpha-cyclodextrin and have larger specific surface and more flourishing hole, be 0.1 ml/g such as the pore volume of alpha-cyclodextrin, and the pore volume of Kiselgel A is 0.35-0.4 ml/g.Select the aerated materials in suitable aperture can make the 1-methylcyclopropene molecule be adsorbed to pore surface, thereby avoided intermolecular owing to contacting with each other and colliding the polymerization that causes.And, the aperture of aerated materials and necessary suitable to the adsorption power of 1-methyl cyclopropene, too strong sorbing material need to just can desorption discharge the 1-methylcyclopropene gas under higher condition; Then at first charge capacity is too little for the too weak words of adsorption power, and secondly the gas of absorption can quick desorption.If adsorption affinity is stronger, its release need to be heated to solution higher temperature and just can carry out, therefore absorption is dragged and can not strong adsorption power be arranged to the 1-methyl cyclopropene, otherwise the time that the aqueous vapor that only relies on the fruits and vegetables respiration to produce will need to grow very much discharges.
So in above-mentioned aerated materials, further be optimized, through repetition test and comparison, select to find that silica gel is most preferred sorbing material.Silica gel (Silica gel) is a kind of high activity sorbing material, and molecular formula is mSiO
2.nH
2O belongs to amorphous substance.The silica gel stable chemical nature, water insoluble and any solvent, nonpoisonous and tasteless, stable chemical nature does not react with any material except highly basic, hydrofluoric acid.
Silica gel is divided into macro porous silica gel, silochrom, Type B silica gel, Kiselgel A according to the size in its aperture.Along with its adsorption power to the 1-methylcyclopropene molecule that diminishes in aperture strengthens gradually, therefore can select the silica gel in suitable aperture to adsorb to control the speed of desorption process according to different fresh-keeping requirements, because need the effect of " slowly-releasing " at the preserving fruit and vegetable utilizing of some kind.
With silica gel adsorption 1-methyl cyclopropene with alpha-cyclodextrin Adsorption Phase ratio plurality of advantages is arranged.At first, silica white is cheap adsorbent, and this has guaranteed the cheap price of this fresh-keeping cartridge bag; Secondly, silica gel has larger charge capacity, because alpha-cyclodextrin and 1-methyl cyclopropene are the molecular complex of 1:1, this has determined that the highest content of this complex compound 1-methyl cyclopropene only is 5.26%, and commercial this complex compound discharges and stable other auxiliary agent that also added in complex compound for guaranteeing, this has further reduced the content of effective constituent in the complex compound, only be 3.3% such as the most widely used a kind of complex compound 1-methyl cyclopropene content, and silica gel adsorption 1-methyl cyclopropene can reach about 8%; Again silica gel adsorption process is simple, it is namely adsorbable to carry out gas-solid contact under drying regime, and the absorption of alpha-cyclodextrin need to be carried out in its aqueous system, this has caused the rear solution of the alpha-cyclodextrin dissolving complexing of part complexing to be lost efficacy, alpha-cyclodextrin after complexing-solution complexing process reaches chemical equilibrium in the solution has just lost adsorption power, and this has further increased the complexity of productive costs and technique; The 4th, the 1-MCP dispose procedure of silica gel adsorption is simple, and the air that only makes its contact have certain humidity can be realized discharging, and 1-MCP/ alpha-cyclodextrin complex compound need to be dissolved in the alkali lye and just can discharge.
On absorption carrier 1-MCP being adsorbed is its prerequisite that discharges 1-MCP, and concrete described absorption is to make the 1-methylcyclopropene gas carry out gas-solid the contact with the aerated materials of drying to adsorb down with carrying in the protection of unreactable gas.Thereby the purpose of using unreactable gas is the probability that the 1-MCP gas molecule is isolated from each other reduce collision polymerization between them, and suitable unreactable gas comprises nitrogen, helium, argon gas etc., but nitrogen most preferably.The adsorption process enlarge active surface of should trying one's best, suitable mode are to select the sorbing material of suitable particle diameter that it is under the effect of air-flow to seethe or " fluidisation " state.For extending contact time, also the 1-MCP gas of inert gas shielding can be circulated with air pump, until adsorb saturated.
The concrete following examples of passing through are come absorption and the release of 1-MCP are described:
In the 100mL four-hole boiling flask, add successively 10mL liquid paraffin, 10g powder Sodamide and 0.4 gram hexamethyldisilazane; under nitrogen protection, be heated with stirring to after 50 ℃ and within 1 hour time, 20g 3-chloro-2-methyl propylene dropped in the flask; the gas that generates passes through two Drexel bottles successively under the carrying of nitrogen; the aqueous sulfuric acid of 1mol/L wherein is housed in first Drexel bottle, and it is the 4:4:2=deionized water that volume ratio is housed in second aspirator bottle: isopropyl alcohol: the mixed solution of monoethanolamine.Gas after the washing passes into after by the dry pipe that the calcium chloride desiccant is housed in the flask that 50 grams, 100 purpose Type B silica whites are housed, and flask is connected with mixing device, and adsorption process is kept high-speed stirred all the time.Before using, silica gel activates 20 hours 120 ℃ of dryings.
The weight of silica gel is 53.1 grams and no longer changes after about 2 hours, illustrates that absorption is saturated, and the content of 1-MCP is 5.84% in the silica gel.
Repeat the operating process of embodiment 1, just Type B silica gel is substituted with Kiselgel A and adsorb.Adsorb that 1-MCP content is 6.92% in the saturated rear silica gel.
Because Kiselgel A is compared with Type B silica gel larger specific surface and less aperture is arranged, so its saturated extent of adsorption is greater than Type B silica gel.
Repeat embodiment 1, just replace Type B silica gel with atlapulgite, the content that adsorbs 1-MCP in the saturated rear carclazyte is 0.3%.
Embodiment 4 releases of 1-MCP gas from Type B silica gel and Kiselgel A
It is 90% leakproof tank that the silica gel of absorption after saturated in embodiment 1 and 2 is placed on relative humidity with filter paper packaging respectively, regularly detects gas residue in the silica gel with gas chromatographic method.Testing result shows that Type B silica gel discharged fully at about 1 hour, and Kiselgel A discharged fully about 4 hours.
Embodiment 5 preserve tests
To the double centner pear of certain orchard picking its flesh firmness of sampling Detection (unit: newton N), pulp pH value and have or not brown stain after it is divided in (each 50 kilograms) in two PE bags;
Put into wherein one bag and airtight after the silica gel that absorption among the 0.2 gram embodiment 1 is saturated encapsulates with filter paper, this bag is numbered the A bag; Other one bag is left intact as blank assay, is numbered the B bag.
With these two bags of fruit 25 ℃ placed for two weeks after its flesh firmnesses of sampling Detection (unit: newton N), pulp pH value and have or not brown stain, the result is as shown in the table:
