Problems solved by technology

At present, there is no research on the changes in food composition and quality after pulsed intense light sterilization in the prior art; at the same time, there is little research on the application and effect of pulsed intense light sterilization in different foods, and natural casings use pulsed intensity The intensity and process required for light sterilization cannot be copied. It must be determined through careful research. It is necessary to expand the application of pulsed strong light sterilization technology in food systems with different water contents and different chemical compositions.

Abstract

The invention discloses a pulsed light sterilization method for natural casings. The method comprises the steps: carrying out pulsed light sterilization for the first time on the casings; and then carrying out pulsed light sterilization for the second time on the casings which are in vacuum sterile packages, wherein the pulsed light sterilization intensity for the first time is 3-7 J/cm<2>, the flashing distance is 8-15 cm, the flashing times are 20-30 seconds respectively on the positive and negative faces, and 5-7 times of the pulsed light are flashed every second; the pulsed light sterilization intensity for the second time is 1-3 J/cm<2>, the flashing distance is 20-30 cm, the flashing times are 5-10 seconds respectively on the positive and negative faces, and 2-4 times of the pulsed light are flashed every second. According to the method disclosed by the invention, the pulsed light sterilization technology is applied to natural casing production for the first time, and relying on the synergistic effect among infrared, visible and ultraviolet wavelength light of pulsed light, the sterilization effect is remarkable.

Description

technical field [0001] The invention belongs to the technical field of natural sausage casing processing, and relates to the application of pulse strong light sterilization technology in casing production. Background technique [0002] Natural sausage casings are sausage casings made from the esophagus, stomach, small intestine, large intestine, bladder and other organs of healthy livestock after deep processing. According to different processing methods, they are mainly divided into salted casings and dry casings. However, natural sausage casings are rich in protein and fat, and are susceptible to microbial contamination and deterioration. At present, preservation is mainly done by salting or / and drying. The process is cumbersome and consumes a lot of salt. In the later production of sausages, the casings must be rinsed and desalted first. At the same time, the discharge of concentrated brine will also cause the surrounding soil and water The salt content in resources grea...
