Abstract

Abstract

In order to apply pulsed light techniques in sterilization for instant Pleurotus eryngii products,a series of experiments were taken firstly to confirm proper flash time and flash mode of the pulsed light,then to compare its effect on the color and texture of instant products and the sterilization,finally to study the application with pulse light in assisting to heating and biological bacteriostatic agent on instant Pleurotus eryngii products.The results showed that the best effect of pulsed light was flashing 20 son both sides of the products and was irradiated after packaging.There were no significant influence of 20 sflash of pulsed light sterilization on the sensorial quality(color,texture)of instant Pleurotus eryngii,and killing rate in surface stained Escherichia coli,Bacillus subtilis and Staphylococcus aureus' was 98.34%,91.42%,98.73%,respectively.The products with radiating both sides for 20 s,then sterilizing 20 min in boiling water and adding Nisin 50mg·kg-1,their shelf life could be lasted for 60 days with qualified sensorial quality and the colony of the products met the quality requirements.The experiments provided theoretical basis in applying pulsed light techniques for processing of instant Pleurotus eryngii products.
