In the present study, a microbiological challenge test in artificially contaminated raw milk cheese during cheese-making was carried out. Raw ewe milk was contaminated by a suspension of particular strains. The number of and dynamic growth were evaluated during cheese-making and storage. A significant decrease of the viable count of was observed during ripening and viable count was below the limit of quantification during storage. The results show that the product is unable to support the growth of the pathogen.
在本研究中,对奶酪制作过程中人工污染的生乳奶酪进行了微生物挑战试验。用特定菌株的悬浮液污染生羊奶。在奶酪制作和储存过程中评估了(相关微生物的)数量和动态生长情况。在成熟过程中观察到(相关微生物)活菌数显著下降,并且在储存期间活菌数低于定量限。结果表明该产品无法支持病原体的生长。
