Abstract
A kind of fruits and vegetables, food preservation film are the tablets that is processed with known pressed-disc technique after the mixing and stirring according to a certain percentage by pyrosulfite or sec-butylamine etc. and adhesive, auxiliary agent.This product is placed in the packing container of fruits and vegetables, food, freshness-retained 1～June.This product not only is fit to large-scale storehouse, and suitable fruits and vegetables, food specialist, the market of farm produce, the fresh-keeping usefulness in shop and family, and easy to operate, and the influence of food and environment is all met government standard.
Description
The invention belongs to a kind of Chemical composition that really thin, food preservation that is used for, specifically a kind of fruit is dredged, food preservation film.
Fruit is dredged, the storage fresh-keeping of food has machinery, physics with chemistry etc. the whole bag of tricks.For example, the usefulness that has low-temperature receiver cryopreservation artificial or nature is as the disclosed technology of CN85104856, CN86108168; Technology such as the usefulness ozone ion that has, vacuum microwave, atmospherical discharges are 1031471A as CN8610706, CN86107861, CN88105122(publication number) disclosed method; The improvement packing that has is as the disclosed Chinese herbal medicine composite semipermeable membrane of CN86101578 preservation technique, the disclosed controlled atmospheric packing film of CN87107591; CN86102550, CN87100004 disclose respectively with sodium chloride, citric acid, vitamin C and water and with potassium permanganate, quick lime, vermiculite and water and have prepared antistaling agent; The 86104531st, the fresh-keeping composition patent of the Soviet Union non-blackland grassland flower subregion scientific research place China application; be formulated with monoglyceride, single-acetyl triglyceride, succinyl or lactoyl monoglyceride salt, food antiseptics and water; to really dredge and soak some minutes therein; then at air drying, thus preservation and freshness.Above various methodologies, the only suitable bulk storage plant that has, the technical sophistication that has, the troublesome poeration that has.Fruit is dredged, food from the place of production to consumer's hand, often will be through repeatedly collecting and distributing transfer process, above-mentioned all multi-methods obviously can not adapt to.
The objective of the invention is for fruit is dredged, food provides a kind of not only economy in the whole process of circulation but also preservation method easily.
Design of the present invention be dredge fruit, in the packing container of food (as polybag, carton and the beach wormwood, basket etc. that have straw bag) put a little Chemical composition that easily into, allow it slowly discharge or volatilize and to kill or to suppress harmful microbe gas, air in the purifying vessel, prevent corruption, reach fresh-keeping purpose.This method is applicable to the whole process of circulation.
The present invention realizes like this, select pyrosulfite or sec-butylamine or its esters main component as this composition, because the sulfur dioxide that the former discharges has good killing and inhibitory action to the Penicillium pathogen after Botrytis pathogen, the latter are volatilized, these two kinds of pathogens all are that the thin storage of fruit causes one of rotten The main pathogenic fungi.For it slowly being discharged or volatilizing, can be processed into tablet, promptly be to allow it be dispersed among adhesive and other auxiliary agents, these auxiliary agents not only play diluting effect, and are that tablet processing is necessary, as increase flowability, are convenient to the demoulding etc.Adhesive can be gelatin, polyvinyl alcohol, methylcellulose, carboxymethyl cellulose etc.; Auxiliary agent is stearate and silica particles etc.All various compositions are commercially available industrial goods, and main component with chemically pure reagent for well.
By weight percentage, of the present invention composed as follows:
Pyrosulfite (A1): 90～98%
Stearate: (B): 0.7～4%
Silica particles (C1): 0.7～4%
Adhesive (D): 0.6～2%
For well, B can be alkali metal salt or alkali salt to A1 with alkali metal salt, D with polyvinyl alcohol or methylcellulose for well.More satisfactory composition and proportioning are: A1 is that sodium salt 97%, B are that magnesium salts 1%, C1 1%, D are polyvinyl alcohol 1%.
If main component is used sec-butylamine or its esters, and is then composed as follows:
Sec-butylamine or its salt (A2): 1～4%
Stearate (B): 0.5～1%
Diatomite (C2): 94～96%
Adhesive (D): 1.5～2%
The salt of A2 can be acetate or sulfate, and B and D are the same.More satisfactory composition and proportioning are: A2 is that sec-butylamine 2%, B are that magnesium salts 1%, C2 95%, D are polyvinyl alcohol 2%.
With above-mentioned various components in certain proportion mixed after, be processed into tablet with known tablet process technology and get final product.
Raw material of the present invention is easy to get, and it is single to add break, easy to use, is not only applicable to the warehouse room, and it is fresh-keeping especially to be fit to the thin specialist of fruit, the market of farm produce, shop and family.
Embodiment: to process 1 kilogram of tablet is example.
Get sodium salt 900 grams of A1, each 40 gram of the magnesium salts of B and C1, polyvinyl alcohol (D) 20 grams stir, and are processed into the tablet of every 1 gram with the pressed-disc technique of metric system.
Get sodium salt 980 grams of A1, each 7 gram of the magnesium salts of B and C1, polyvinyl alcohol (D) 6 grams stir, and are processed into the tablet of every 0.5 gram with known pressed-disc technique.
Get sodium salt 970 grams of A1, each 10 gram of the magnesium salts of B, C1 and polyvinyl alcohol (D) stir, and are processed into the tablet of every 1 gram with known pressed-disc technique.
Embodiment: to process 1 kilogram of tablet is example.
Get sec-butylamine (A2), each 10 gram of dolomol (B), diatomite (C2) 960 grams, polyvinyl alcohol (D) 20 grams stir, and are processed into the tablet of every 1 gram with known pressed-disc technique.
Get sec-butylamine (A2) 40 grams, dolomol (B) 5 grams, diatomite (C2) 940 grams, polyvinyl alcohol (D) 15 grams stir, and are processed into the tablet of every 0.5 gram with known pressed-disc technique.
Get sec-butylamine (A2) 20 grams, dolomol (B) 10 grams, diatomite (C2) 950 grams, polyvinyl alcohol (D) 20 grams stir, and are processed into the tablet of every 1 gram with known pressed-disc technique.
During use, with per 5 kilograms of fruit, dredge dish and throw in 10 gram tablets and calculate, dredge the gap in the fruit of the center of carton or straw bag and put a certain amount of antistaling tablet, closed case mouth or tighten bag and mouthful get final product.Through storage fresh-keeping tests such as grape, banana, orange, apple, peach, capsicum, leek are proved, in the time of 0～5 ℃, freshness-retained more than six months, in the time of 5～10 ℃, freshness-retained three～six months, in the time of 10～20 ℃, freshness-retained two～three months, more than 25 ℃ freshness-retained one month.This product detects through " product quality supervision and inspection station, Anhui Province " food inspection portion, and food meets GB 927-84 food standard behind the fresh-retaining preserving, and through " Hefei environmental monitoring station " test, atmosphere pollution meets GB 3095-82 specified standard again.
