鲈鱼半成品辐照灭菌剂量研究
Study on i rradiation steri l ization and dose of semi-finished Micropterus salmoides
摘要
Abstract
In order to regulate the technical conditions of irradiation sterilization for semi-finished Micropterus salmoides (SFMS),we investigated the impacts of irradiation on the microbe quantity,pH value,water holding capacity,color value and volatile components of it in this study, by using different doses ranging from 0.00 to 8.74 kGy of 60 Co gamma ray irradiation.The results showed that, with the irradiation of 3.25 kGy,the total bacteria decreased to 10 CFU/g.Moreover,the total bacteria decreased to 250 CFU/g and 10 CFU/g,at the D 1 0 value of 1 .54 kGy and 3.64 kGy,respectively. At the range of 1 .55 ~4.78 kGy,pH value could be controlled in a reasonable standard.Increasing irradiation dosage (1 .55 ~7.57 kGy) did not change the production of water holding capacity,color,or Warner-Bratzler shear force.A dose of 3.25 kGy was beneficial to semi-finished products of SFMS to reduce the volatile components of benzene and alkanes.In conclusion,the 60 Co-γ irradiation dose in 3.25 ~ 4.78 kGy could release the sterilization purpose.Therefore, our studies provided theoretical guidance for the irradiation steriliza-tion of SFMS.关键词
