Embodiment 1
The present invention provides the economic benefits and social benefits irradiation fresh-keeping method of Antioxidant Enzymes activity in a kind of cold fresh meat of quick activation, including following step
Rapid:
Step one, cold fresh meat is cut into the cube meat that thickness is 15cm；
Step 2, cube meat is packed one by one；I.e. piece of meat block one packaging.
Step 3, will packaging after cube meat be placed in irradiation under electron beam irradiation, irradiation dose is 1.8kGy, irradiation agent
Dose rate is 2500Gy/s；
Step 4, the cube meat after irradiation being carried out cold preservation, refrigerated storage temperature is 0 DEG C, and humidity is 75%.
Described quickly activates in the economic benefits and social benefits irradiation fresh-keeping method that in cold fresh meat, Antioxidant Enzymes is active, obtains in described step one
After cube meat, to the aqueous agar solution that cube meat surface sprinkling temperature is 43 DEG C, wherein, the mass fraction of agar is 0.5%, institute
State in aqueous agar solution possibly together with the water-soluble vitamin c that mass fraction is 0.2%, the watermiscible vitamin E of 0.15%,
The lysozyme of 0.01% and the lywallzyme of 0.02%.The generation of irradiation smell and irradiated food produce oxygen-derived free radicals and peroxide
Relevant, vitamin C and vitamin E are antioxidants, cube meat can be protected to avoid the threat of free radical, thus reduce irradiation
Taste.Lysozyme is a kind of to hydrolyze the alkaline enzyme of mucopolysaccharide in pathogenic bacterium, by destroying the-acetylmuramic acid in cell wall
And the β between NAG-Isosorbide-5-Nitrae glycosidic bond, make the insoluble mucopolysaccharide of cell wall resolve into solubility glycopeptide, cause
Cell wall rupture content escapes and makes bacterolysis.Lywallzyme can decompose fungal cell wall, it is thus possible to extend guaranteeing the quality of cube meat
Phase.After aqueous agar solution solidification, lysozyme, lywallzyme, vitamin C and vitamin E can be uniformly adhered at cube meat
