Sterilization method and treatment device of defrosted meat

Abstract

The invention discloses a sterilization method of defrosted meat. The sterilization method of the defrosted meat comprises the following steps: putting the defrosted meat into an airtight space; continuously introducing ozone and pressurized gas into 1.2 to 1.5 atmospheric pressure in a mass ratio of 1 to (1 to 3), keeping for 2 minutes to 5 minutes, and subsequently continuously introducing introducing the ozone and the pressurized gas into 1.4 to 2.0 atmospheric pressure in a mass ratio of 1 to (10 to 20); turning on an ultraviolet lamp to perform radiation on the defrosted meat, and performing all-surface cycling irradiation sterilization on the defrosted meat through cycling reciprocation motion of the ultraviolet lamp. The invention also discloses a sterilization treatment device of the defrosted meat. According to the sterilization method and treatment device of the defrosted meat disclosed by the invention, comprehensive no-dead-corner sterilization on surface skin of the defrosted meat can be completely carried out in a process of defrosting meat, bacteria breeding of the meat surface skin caused by defrosted water is avoided so as not to affect the level and the quality ofthe meat; and meanwhile, an influence on the taste of the meat is less.

Description

technical field [0001] The invention belongs to the technical field of food and relates to frozen meat processing technology, in particular to a thawed meat sterilization method and a processing device. Background technique [0002] Frozen meat is obtained from poultry, pre-cooled, and frozen below -18°C for several hours, and the temperature of the deep meat is below -6°C. After low-temperature freezing, the protein activity in the meat is weakened. It will be lost immediately, and its color and aroma are not as good as fresh meat or chilled meat, but it has a long shelf life, so it is still widely used. [0003] With the development of the national economy, my country's meat supply has formed an overall pattern dominated by market consumption. Some meat products are also exported to Japan, Southeast Asia and other countries and regions. The meat processing industry occupies a very important role in the national economy. At the same time, there are many problems and deficie...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, when it is necessary to thaw frozen meat, because most of the existing thawing methods are directly thawed indoors, the thawing process of this kind of meat will cause bacterial growth, which will affect the overall quality of the meat.
