摘要
采用不同浓度的乳酸和二氧化氯对冷却前的牛胴体进行喷洒处理,研究了喷洒后对牛胴体及成熟后脖肉中微生物的去污染效果。结果表明,浓度在2.5%以下的乳酸对胴体及其成熟后的脖肉无显著的减菌效果。浓度在100mg/kg及以上的二氧化氯能显著(p<0.05)减少牛胴体表面和成熟后脖肉的菌落总数和大肠菌群;浓度为200mg/kg的二氧化氯比100mg/kg的减菌效果更显著(p<0.05)。
The disinfecting effect of lactic acid (LA) and chlorine dioxide (CLO) on beef carcasses and cuts was evaluated. Different concentrations of LA and CLO were sprayed on the surface of beef carcasses before chilling, respectively. LA had no decontaminating effect at the concentration lower than 2.5%, while CLO could decontaminate beef carcass at a concentration above 100mg/kg (p〈 0.05). Meanwhile, 200mg/kg CLO was more effective than lOOmg/kg CLO (p〈0.05).
