摘要
研究低温储存原料乳中金黄色葡萄球菌的生长情况及其产毒情况,为原料乳的安全储存提供依据。将新鲜原料乳和人工污染金黄色葡萄球菌的原料乳经16℃和20℃培养38h后,进行菌落总数、金黄色葡萄球菌和肠毒素的测定。结果表明,品质合格的原料乳在实验模拟的低温储存过程中,未检测出金黄色葡萄球菌产肠毒素。但是金黄色葡萄球菌仍然是乳制品中主要的致病微生物,可以通过低温储存控制其危害程度。
The growth of and its toxin-producing were studied in order to provide a basis for the safe storage of raw milk. Fresh raw milk and artificial contamination raw milk were inoculated with Staphylococcus aureus and were incubated at 16 ℃ and 20 ℃ for 38 h, the total number of colonies and Staphylococcus aureus and the enterotoxin were determined. The results showed that the there was no enterotoxin be fount in this experimental condition, that induced that at low temperature storage condition, Staphylococcus aureus was not an obvious hazards for raw milk. However, Staphylococcus aureus in dairy products was still the main pathogenic micro-organisms, and it need be controlled by low temperature.
