| 摘 要： | 研究采用水溶性寡聚乳酸溶液作喷雾剂来清洗牛肉表面污染及抑制其细菌生长，中试规模的肉类自动喷洗设备中的试验结果表明：喷嘴压力，肉表面处理时间，喷嘴类型及喷嘴摇摆速度对减少表面微生物数目均有重要影响。寡聚乳酸比水有更好的消除表面细菌污染的效果，可以减少微生物数量10og10(cfu)/cm^2。寡聚乳酸不仅能有效地消除肉类表面污染，而且还能有效地抑制其细菌生长，是一种很有潜力的肉类表面处理剂。 |
| 关 键 词： | 细菌污染 牛肉 低分子量 水溶性寡聚乳酸 肉类表面处理剂 杀菌效果 |

| Abstract: | Low molecular weight, soluble polylactic acid(SPLA) was used as a washing solution to decontaminating the surface of beef. Pressure, exposure time, nozzle type and oscillation speed were most important in reductions of microorganisms when beef contaminated with manure was sprayed using a pilot scale sprayer. SPLA reduced contaminations to a greater extent than water. The microbial numbers were reduced by 4 log 10(cfu). The results indicates that SPLA is an effective microbial decontaminant in beef processing industry. |
| Keywords: | beef decontamination low molecular weight soluble polylactic acid(SPLA) |
