| 摘 要： | 采用5 T以上高强度脉冲磁场处理鲜腐乳,研究了脉冲强磁场对腐乳中微生物的影响,结果表明:高强度脉冲磁场对腐乳的杀菌效果显著,随着磁场强度的增大或脉冲数的的增加,菌落总数和霉菌酵母存活率基本呈下降趋势,但出现谷值后,两者的存活率随着磁场强度和脉冲数的进一步增大有所回升.其中在磁场强度为16.02T、脉冲数为6个时对腐乳中菌落总数的杀菌效果最好,而在磁场强度为16.02 T、脉冲数为8个时对霉菌酵母的杀菌效果最好,与菌落总数相比,霉菌酵母对脉冲磁场有较强的抵抗力.

| Abstract: | The effect of intense pulsed magnetic field on total numbers of colony,mould and yeast was investigated by using pulsed magnetic field over 5T to treat sufu.The experimental results indicated that the sterilizing effect of intense pulsed magnetic field on sufu was significant.The survival rate firstly reduced to a valley value with the magnetic field strength and pulse number increasing.Then,the survival rate began to rise with the magnetic field strength and pulse number increasing,and the sterilizing resu... |
