Abstract
The invention provides a method for degrading acetamiprid residue on the surface of the fruit of Chinese wolfberry by irradiation. In the method, electronic beams of certain energy and certain dose irradiate the fruit of Chinese wolfberry to degrade the acetamiprid residue on the surface. The method is characterized in that under a carton package, the electronic beams with the energy of 5-10MeV and irradiation dose of 1-10kGy are used for irradiating the fruit of Chinese wolfberry. The acetamiprid residue on the surface of the fruit of Chinese wolfberry is effectively degraded, and larger application value for expanding the export of the fruit of Chinese wolfberry is realized.
Description
Technical field
The invention belongs to irradiation technique application, also belong to Safety of Food Quality control field, specifically the method for irradiation-induced degradation fruit of Chinese wolfberry surface acetamiprid residue.
Background technology
Because the fruit of Chinese wolfberry has good health-care effect, consumption figure at home and abroad increases year by year in recent years, but the residues of pesticides excessive problem of the fruit of Chinese wolfberry seriously limits the development of fruit of Chinese wolfberry industry.Using chemical pesticide is the important means of preventing and kill off matrimony vine disease, worm, crop smothering.Acetamiprid uses more pesticide in China's matrimony vine artificial growth, although it effectively can prevent and treat the aphid in matrimony vine after using, improve yield of medlar, but its residue accumulation in matrimony vine will cause matrimony vine security to reduce, and cause negative effect to consumer health.Therefore, how research reduces acetamiprid residue amount in the fruit of Chinese wolfberry and has great importance.
In recent years, irradiation, as a kind of new technology improving food security and Shelf-life, obtains concern and the application of increasing country and international organization, is also day by day manifesting its huge economic and social benefit.The FAO/IAEA/WHO food irradiation safe and sanitary joint specialist committee points out, can not cause toxicologic harm at 10kGy dosage with any food of internal irradiation.Research shows that irradiation is on degraded Pesticide Residues, it is a kind of highly effective method, irradiation-induced degradation agricultural chemicals is the various high-energy rays utilizing the ionising radiation such as radio isotope or high-power electron beam to produce, the various chemical bonds of agricultural chemicals are ruptured under the high-energy effect of ray, thus be degraded into micromolecular process (Scientia Agricultura Sinica, 2010, (5): 1041-1049).Radiation processing technology is applied to the degraded of fruit of Chinese wolfberry surface acetamiprid residue by the present invention, at home and abroad have not been reported by literature search.
Summary of the invention
The object of this invention is to provide a kind of method that can reduce fruit of Chinese wolfberry surface acetamiprid residue, the irradiation technique parameter best to fruit of Chinese wolfberry surface acetamiprid residue degradation effect is provided.
In order to achieve the above object, the invention provides the method for a kind of irradiation-induced degradation fruit of Chinese wolfberry surface acetamiprid residue, comprising following steps:
1) fruit of Chinese wolfberry is adopted packed in cases, the ulking thickness of the fruit of Chinese wolfberry in carton is 15 ~ 50cm;
2) have the carton of the fruit of Chinese wolfberry to be placed on conveyer packaging, the transporting velocity of described conveyer is 0.02 ~ 0.3m/s;
3) fruit of Chinese wolfberry be placed on conveyer accepts the electron beam irradiation that electron accelerator produces;
4) spin upside down carton, the fruit of Chinese wolfberry accepts secondary irradiation through conveyer by electron accelerator scanning window;
5) after irradiation, acetamiprid residue in the fruit of Chinese wolfberry is detected.
The method of the irradiation-induced degradation fruit of Chinese wolfberry of the present invention surface acetamiprid residue, wherein said step 1) in the fruit of Chinese wolfberry be the fresh or dry Chinese wolfberry fruit of matrimony vine of solanaceae plant.
The method of irradiation-induced degradation fruit of Chinese wolfberry surface of the present invention acetamiprid residue, wherein said conveyer is belt, roller rod-type or chain type.
The method of irradiation-induced degradation fruit of Chinese wolfberry surface of the present invention acetamiprid residue, wherein said step 3) and step 4) in the energy of electron beam be 5 ~ 10MeV, line is 0.3 ~ 20mA, beam power is 10 ~ 20kW, maximum sweep width is 100cm, and scan frequency is 5 ~ 15Hz, and irradiation dose is 1 ~ 10kGy, operating temperature is set within the scope of 5 ~ 35 DEG C, and ambient humidity is limited in and is not more than 60%.
The invention has the advantages that:
(1) method of irradiation-induced degradation fruit of Chinese wolfberry surface of the present invention acetamiprid residue, the electron beam irradiation that the electron accelerator adopted produces has higher energy, effectively can reduce the concentration of fruit of Chinese wolfberry surface Acetamiprid, improve the security of the fruit of Chinese wolfberry, and energy desinsection, sterilization, and do not affect its edible quality, for raising fruit of Chinese wolfberry quality and security open up a new way, have broad application prospects and great economic implications;
(2) method of irradiation-induced degradation fruit of Chinese wolfberry surface of the present invention acetamiprid residue, electron accelerator irradiation technology is adopted to belong to emerging radiation processing technology, irradiation efficiency is high, irradiation evenness is good, processing safety is strong, and equipment control is simple, strong adaptability, be easy to combine with existing fruit of Chinese wolfberry processing technology, be easy to realize industrialization;
(3) method of irradiation-induced degradation fruit of Chinese wolfberry surface of the present invention acetamiprid residue, safety and sanitation, noresidue, free from environmental pollution, low-carbon energy-saving, can be cost-saving.
