Abstract
The invention discloses a grain storage method comprises the following step: placing a fumigation agent below or/and around a grain pile under an environment at room temperature to 40 DEG C, wherein the fumigation agent is a mixture of a thiosulfinate type compound and a sulfo-sulphonate type compound. The grain storage method realizes safe and effective sterilization and disinfection for grains, and has the advantage of green environment friendliness; particularly, one-time treatment of various grains and various germs and moulds under the same fumigation environment can be realized; furthermore, no germ or mould reappears even if the grains subjected to fumigation treatment can be stored for at least half a year or longer in a granary environment or under a transportation condition; meanwhile, the method further has the advantages of simplicity in operation, low cost, large application range to grains, germs and moulds and the like, and has important value and far-reaching significance for safe and long-time storage of the grains.
Description
Technical field
The present invention is to be related to a kind of food storage method, belongs to grain Techniques of preserving field.
Background technology
Report national 60709.9 ten thousand tons of total output of grain (1,214,200,000,000 jin) according to State Statistics Bureau within 2014, increased than 2013
5160000 tons (103.2 hundred million jin), increase by 0.9%.Member of the national committee of CPPCC, State Grain Administration chief appoint just know May in this year ginseng
Plus represent when interviewing the reporter during Chinese People's Political Consultative Conference's Team Conference: at present, China's annual grain loss wastage is 1000
Hundred million jin about, it is about as much as the first granary province of China Heilongjiang Province's grain yield of a year.Grain produces from ground
Come out to and lay out dining table, each link all has loss and waste phenomenon.According to measuring and calculating, China's grain only stores, transports puerperal,
The intermediate links loss and waste total amounts such as processing reach 70,000,000,000 jin about, only grain storage link loss about 40,000,000,000 wherein in intermediate links
Jin.China annual puerperal mould fall grain loss should not be underestimated, it is serious that funguses and endotoxin contamination cause to China's grain security
Threaten.According to Institute of Agricultural Product Processing, Chinese Academy of Agricultural Sc's researcher's Liu Yang introduction: " the annual input of China is exceeded 100 billion with all strength
Strive for 1% increases in grain production, but up to 21,000,000 tons of the grain post-harvest loss causing because going mouldy every year, account for national total grain output
The 4.2% of amount, the direct economic loss causing is about 180 hundred million to 240 hundred million yuan.”
In addition, mycotoxin pollution also seriously restricts China's Foreign Trade.In recent years, the peace that mycotoxin contaminated food products causes
Total event takes place frequently, and not only seriously threatens China's human and livestock health, also restricts agricultural products in China foreign trade simultaneously.From 2002～2011
It is close on after 10 Nian Zhong China's export European Union eat agricultural product relevant contravention statistical analysiss and find: remain in heavy metal, agricultural and veterinary chemicals etc.
In the factor of numerous restriction China's Foreign Trade, mycotoxin is exceeded to be topmost reason, the fault causing because of mycotoxin
Event reaches 28.6%.It is reported that, mycotoxin is abiogenous food contaminant the most dangerous, and the poison of aflatoxin
Property be 10 times of potassium cyanide, 68 times of arsenicum, be to cause one of main inducement of hepatocarcinoma.Mycotoxin is mainly producing
Produce during foodstuff preservation afterwards, during China's foodstuff preservation, mycete is with Aspergillus flavus, Asia Fusarium spp., cereal sickle
Based on knife bacterium；In American-European countries, except mycete is in addition to Aspergillus flavus, Fusarium graminearum, also aspergillus parasiticus, fusarium culmorum.With
When, short with American-European countries grain storage storage phase, source is single, compares the features such as quantity is little, China's grain storage feature is mainly shown as
Content of molds height, storage phase length, wide material sources, miscellaneous, quantity wide in variety are big.
At present, most of grain depots are buried and the modes such as inserting tube method fumigant insect killing using grain face dispenser, cloth bag, fumigant master used
Hydrogen phosphide to be, oxirane, bromomethane and vikane, with the raising of people's environmental protection and safety consciousness, above fumigant
Limitation progressively embody, such as: hydrogen phosphide is causing toxicity by force, infringement lung, the heart, liver, kidney, central nervous system and bone
Bone, over-exposure causes asthma, pneumonia or pulmonary fibrosis disease, and the easily unsafe factor such as spontaneous combustion；Oxirane
Mutagens and explosivity；The destructiveness of the ozone to atmospheric advection layer for the bromomethane and direct mankind's generation is poisoned have caused people
Highest attention.Start from after 1997 the 9th time " Montreal Protocol Meeting of States Parties ", developed country is about
Fixed use bromomethane disinfectant phased out from 2005, China also " Montreal in April, 2003 official signature
Protocol " Copenhagen amendment, promise will stop before 1 day January in 2015 comprehensively methyl bromide agricultural, storage, cigarette
Use in the industries such as grass.Certainly, grain sterilization also will execute this promise；Vikane is a kind of at normal temperatures and pressures
Colourless, poisonous, have strong and stimulating gas, acute toxicity major determinant central nervous system, cause convulsions；In addition, also can
Skeleton deposits, there is progressive poisoning dangerous.Current research finds chemical fumigant vikane, is dispersed into air
After can become a kind of potent greenhouse gases, it is one kilogram of dioxy to the effect of global warming that one kilogram of vikane is discharged in air
Change carbon 4800 times；Although present in the air only exists minimal amount of vikane, about 1.5 part per trillions, i.e. every 1,000,000 skies
In edema caused by disorder of QI, only 1.5 is vikane, but it is being increased with annual 5% speed, is not used as the replacement of bromomethane
Thing, the application of vikane and the atmospheric warming effect that causes should cause enough attention！
In sum, solving grain problem of going mouldy has become the great demand ensureing national food security, explores and is suitable for China grain
In food storage, effective preventing control method of mycotoxin has become the current research topic be badly in need of and solving.
Content of the invention
The problems referred to above existing for prior art and demand, it is an object of the invention to provide a kind of environmental protection, safely and effectively
Food storage method.
