摘要
从卡西亚斯省(Duque de Caxias / RJ)超市购买的19份Minas Frescal奶酪样品进行了以下微生物学分析:采用两种不同的方法,用乳酸杆菌肉汤对总大肠菌群和耐热大肠菌群、凝固酶阳性葡萄球菌和乳酸菌(LAB)进行了计数。以DE MAN、ROGOSA、SHARPE和10%的重组奶粉为肉汤,添加0.05%葡萄糖和0.1%酵母提取物。在分析的19份样本中,有10份(52.6%)的耐热大肠菌群高于现行立法规定的水平,均为大肠杆菌。在分析的19个样本中(100%),葡萄球菌计数高于法例所容许的水平。对于BAL计数,除了在所有样本中观察到的低计数外,使用MRS Broth的方法更有效。根据研究结果,有必要采取措施提高食品基质的微生物质量,确保食品安全。
Microbiological analysis of "Minas Frescal" cheese commercialized in Duque de
Caxias/RJ
Nineteen samples of Minas Frescal cheese that were obtained from supermarkets in Duque de Caxias / RJ and submitted to the following microbiological analysis: enumeration of total and thermotolerant coliforms, Staphylococcus coagulase positive and lactic acid bactéria (LAB) from two different methodologies, using Lactobacillus broth acc. to DE MAN, ROGOSA and SHARPE and the Broth of reconstituted milk powder to 10%, supplemented with 0.05% glucose and 0.1% yeast extract. Among the 19 samples analysed, in 10 (52.6%) was observed thermotolerant coliforms above the established in the current legislation, all confirmative for Escherichia coli. In the 19 samples analysed (100%) were observed Staphylococcus counts higher than permitted in legislation. Regarding the BAL count, in addition to the low count observed in all samples, the method using MRS Broth was more effective. In view of the results obtained, it is necessary to adopt measures aimed at improving the microbiological quality of the food matrix and ensuring food safety.
