Embodiment 1

[0017] S1. Cut the meat: remove the fat and connective tissue on the surface of the beef, divide it according to the length × width × height = 50cm × 30cm × 2cm, and divide it along the texture of the beef;

[0018] S2. Vacuum packaging: Vacuum-pack the cut meat in S1 in a vacuum packaging bag with a thickness of 10 silk, and spray 0.15% oregano essential oil on the inner layer of the bag.

[0019] S3. Irradiation treatment: the vacuum-packed meat in S2 is irradiated by a low-energy electron accelerator with an energy of 0.1 MeV, and the irradiation dose is 12 kGy;

[0020] S4. Low-temperature storage: store the irradiated meat in S3 at 0-4°C.

Embodiment 2

[0022] S1. Cut the meat: remove the fat and connective tissue on the surface of the beef, divide it according to the length × width × height = 50cm × 30cm × 2cm, and divide it along the texture of the beef;

[0023] S2. Vacuum packing: vacuum pack the cut meat in S1 in a vacuum packing bag with a thickness of 10 silk, and spray 0.5% cinnamon essential oil on the inner layer of the bag.

Abstract

The invention relates to the technical field of food, and particularly discloses a method for prolonging the shelf life of meat products through low-energy electron beam irradiation, and the method comprises the following steps: S1, segmentation and trimming of meat; s2, vacuum packaging; S3, irradiation treatment; and S4, low-temperature storage. The method has the beneficial effects that a low-energy irradiation technology is combined with vacuum packaging, so that the organoleptic quality and nutritional value of the meat are not influenced while microorganisms are killed, a relatively long shelf life is obtained, and a new technology is provided for fresh-keeping storage of the meat products.

Description

technical field [0001] The invention relates to the technical field of food, in particular to a method for extending the shelf life of meat products by irradiation with low-energy electron beams. Background technique [0002] Meat is one of the main foods of human beings, rich in protein, lipid and various vitamins, but the short shelf life of meat has become a major factor hindering its development. How to extend the shelf life of meat products while ensuring the quality of them has become a research hotspot and difficulty. [0003] Food irradiation can use ionizing radiation to interact with substances, so as to achieve the effect of sterilization and preservation. Compared with traditional sterilization methods, irradiation can reduce microbial contamination without any residual substances while retaining the edible value of food. At present, gamma rays and electron beams produced by electron accelerators are mainly used for food irradiation. Existing studies have show...
