Embodiment 1

[0030] An irradiation preservation process for fresh animal source food, comprising the following steps:

[0031] Step 1. Take cold fresh meat and cut it into several meat pieces with a thickness of 15cm;

[0032] Step 2, packing the meat pieces in separate bags;

[0033] Step 3. Place the packaged meat pieces in a single layer under the electron beam irradiation device for irradiation, the irradiation dose is 1.4kGy, and the irradiation dose rate is 2200Gy / s;

[0034] Step 4, refrigerating the irradiated meat pieces, the refrigerating temperature is 0° C., and the humidity is 70%.

Embodiment 2

[0036]Step 1. Take cold fresh meat and cut it into several meat pieces with a thickness of 20cm;

[0037] Step 2, packing the meat pieces in separate bags;

[0038] Step 3. Place the packaged meat pieces in a single layer under the electron beam irradiation device for irradiation, the irradiation dose is 2.2kGy, and the irradiation dose rate is 2600Gy / s;

[0039] Step 4, refrigerating the irradiated meat pieces at a temperature of 4°C and a humidity of 85%.

Abstract

The present invention discloses an irradiation freshness-keeping technology of raw and fresh animal source food. The technology comprises the following steps: firstly, cold and fresh meat is taken, the taken meat is cut into several meat blocks with a thickness of 15-20 cm; secondly, the meat blocks are sub-bag packed; thirdly, the packed meat blocks are placed under the irradiation of an electron beam irradiation device in a manner of single layer under a irradiation dose of 1.4-2.2 kGy and a irradiation dose rate of 2200-2600 Gy/s; and fourthly, the irradiated meat blocks are subjected to a cold storage. By regulating the dose rate, the quality of the irradiated cold and fresh meat is greatly improved, the microorganisms can be killed quickly, the original texture, color, nutrition, flavor, etc. of the meat blocks can be better maintained, and the meat blocks have a long storage period. The technology is simple in operation and high-efficient, at the same time improves the function of the dose rate, reduces the irradiation damage, is green, safe and convenient, widely achieves the irradiation of agricultural products, keeps quality and freshness, and extends shelf life.

Description

technical field [0001] The invention relates to the technical field of meat products processing. More specifically, the present invention relates to an irradiation preservation process for fresh animal source food. Background technique [0002] Irradiation is an important cold sterilization technology, which is efficient, green and safe, and has been successfully applied in the fields of agricultural product preservation, quality and safety control. However, as the irradiation dose increases, the bactericidal effect increases, but the color, smell, texture, and nutritional content of fresh animal-sourced foods will change drastically, and the quality will drop sharply, which is difficult for consumers to accept. Sterilization, freshness preservation and quality control are difficult to achieve in the irradiation processing of fresh animal source foods - a bottleneck problem in this industry, which has always limited the application of irradiation in high value-added fresh a...
