摘要
目的:研究评价脉冲式均质器在食品微生物检测前处理上的效果。方法:通过对微生物的杀灭影响试验,并与国家标准方法中的拍打法、搅拌法进行比对试验。结果:脉冲振荡处理样品稀释液不会对微生物造成杀灭作用。经F检验,除蜜饯类脉冲法P﹤0.05,结果偏高外,其他类食品P﹥0.05,三法无显著性差异。本法重复性满足实验要求。结论:脉冲式均质器均质效果良好,方便实用,可以广泛应用于食品微生物检测中,能改善传统前处理的某些不足之处,提高检测的准确率。
Objective：To study and evaluate the effect of pulsed homogenizer in pretreatment of food microbiological detection.Methods： The germicidal effect test was carried out and compared with the national tapping and stirring method.Results： No germicidal effect was observed when the sample dilution was treated using pulsed homogenizer.By F test,there was no significant difference among the three methods,except that the result of preserved fruits using pulsed homogenizer was higher（P0.05）.The reproducibility of this method can meet the experiment requirement.Conclusion： Pulsed homogenizer can be used in pretreatment of food microbiological detection,since it can present a good homogenizing effect,which is convenient and practical.Moreover,it can overcome some shortcomings of conventional pretreatment methods to improve detection accuracy.
