60CO-γ射线和电子束辐照对冷鲜鸡保鲜效果的异同性研究
Effects of 60Co-γ Ray and Electron Beam Irradiation on the Preservation Effect of Chilled Chicken
摘要
Abstract
To investigate the impact of 60Co-γ ray and electron beam(E-beam) irradiation on the microbial content of chilled chicken and the similarities and differences of meat quality,vacuum packaging chilled chicken was treated through 2.5 kGy dose of 60Co-γ ray and electron beam irradiation.The total viable counts (TVC),coliform,malondialdehyde,pH value,tenderness,water-holding capacity,TVB-N and chroma within the storage period were measured.The results showed that 60Co-γ ray and electron beam irradiation could effectively decrease total viable counts in chilled chicken,in which the coliform could not be detected.The malondialdehyde,lactic acid,pH and TVB-N of two irradiation treatments all showed an increase trend.Compared with the control group,the L* value and the a* value of the two irradiation treatments were significantly higher,and the L* value and the a* value of the electron beam treatment group were significantly higher than those of the γ ray treated group.However,the b* value of the control group was significantly higher than those of the two irradiation treatments during the same storage period.Those results showed that both of 60Co-γ ray and electron beam irradiation had a significant effect on the microbial content and meat quality of chilled chicken,which provided a scientific basis for the application of irradiation in the storage of chilled chicken.关键词
