Embodiment 1

[0025] A method for applying X-rays to sterilize and keep perch fillets, comprising the following steps:

[0026] a) Remove the head and viscera of the sea bass first, and cut it into fillets. The width of the sea bass fillets is 3cm;

[0027] b) The fish fillets are subjected to X-ray treatment, the irradiation dose is 1.5kGy, the irradiation temperature is normal temperature, and the normal temperature is preserved.

Embodiment 2

[0029] A method for applying X-rays to sterilize and keep perch fillets, comprising the following steps:

[0030] a) First remove the head of the sea bass, remove the internal organs, and cut into fillets. The width of the sea bass fillets is 10cm;

[0031] b) The fish fillets are subjected to X-ray treatment, the irradiation dose is 1.5kGy, the irradiation temperature is normal temperature, and the normal temperature is preserved.

Embodiment 3

[0033] A method for applying X-rays to sterilize and keep perch fillets, comprising the following steps:

[0034] a) Remove the head and viscera of the sea bass first, and cut it into fillets. The width of the sea bass fillets is 3cm;

[0035] b) The fish fillets are subjected to X-ray treatment, the irradiation dose is 1.5kGy, and the irradiation temperature is normal temperature, then vacuum-packed with a composite polyethylene bag, and stored at room temperature.

Abstract

The invention discloses a method of applying an X-ray to sterilize and preserve bass slices and an application thereof, belonging to the technical field of food preservation. The method comprises the following steps: a), removing the head and the internal organs of a bass, and then cutting the bass into slices; and b), carrying out an X-ray treatment to on the slices, wherein the irradiation dose is 1-.5-3.0 kGy. The technical scheme of the invention has the advantages as follows: 1, the X-ray sterilization effect is completethorough; 2, original flavor and ingredients of the food can be kept; 3, the method is sanitary and safety with no residues and or artificial radioactivity; 4, the X-ray is generated by bombarding a heavy-metal target through high-speed electrons generated by an electron accelerator, has the characteristics of good accelerator controllability and no radioactive source; and 5, a synthetic preservation treatment is carried out to on the slices, so that preservation time is increased.

Description

technical field [0001] The invention belongs to the technical field of food preservation, and in particular relates to a method for sterilizing and preserving perch fillets by using X-rays and an application thereof. Background technique [0002] Irradiation sterilization technology is to use radiation to transfer energy and charge to food and living microorganisms and insects in food, so that their metabolism, growth and development, physiological and biochemical reactions and other life activities are affected by radiation to cause enzyme passivation and various damage, resulting in abnormal metabolic growth, damage expansion and even death. The characteristic of radiation sterilization is that it does not increase the temperature of the product, and is suitable for the sterilization of certain heat-labile substances. The most widely used are gamma rays, X-rays and ultraviolet rays. The gamma ray has strong penetrability, which can realize the sterilization of thicker sam...
