摘要
研究了培养温度和培养基对阻抗法快速检测生鲜奶菌落总数的影响。结果表明,采用阻抗测定培养温度30℃、MPCA培养基可实现对生鲜奶菌落总数的快速检测。与传统方法相比,采用阻抗法进行生鲜奶中菌落总数的测定具有快速、简便、准确的特点,不合格样品检验周期少于7 h。
Effects of cultural temperature and media on rapid detection for aerobic bacterial count in raw milk using impedance method were studied in this paper, The experiment results indicated that rapid detection could be achieved when the cultural temperature was set to be 30 ℃ and using MPCA media. Compared with the traditional methods, the impedance detection for aerobic bacterial count in raw milk shows superiorities such as tilne-saving, convenience and accuracy. Using this method, the inspection period of unqualified milk sample is less than 7 h.
