Abstract

A survey of the microbiological quality of commercial tempeh was done in The Netherlands. A total of 110 samples were examined. Most (98%) of the samples had an aerobic plate count above 10 CFU/g. Numbers of Enterobacteriaceae exceeded 10 CFU/g in 67% of the samples, whereas numbers of lactic acid bacteria exceeded 10 CFU/g in 81% of the samples. Staphylococcus aureus was found in 13%, Bacillus cereus in 11% and Escherichia coli in 3% of the samples at levels of 10 CFU/g. Yersinia enterocolitica was found in six samples, whereas Salmonella was absent in 25 g of all the samples examined. Many (69%) of the samples had a yeast count above 10 CFU/g. Trichosporon beigelii was the most frequent yeast species. Besides Rhizopus oryzae and Rizopus oligosporus , which obviously represent the mold species responsible for the fermentation, Mucor indicus was often associated with the mycoflora of the tempeh. The reasons for the poor microbiological quality are discussed and some recommendations are proposed.

摘要

在荷兰对市售豆豉的微生物质量进行了一项调查。共检测了110个样本。大多数（98%）样本的需氧平板计数高于10 CFU/g。67%的样本中肠杆菌科细菌数量超过10 CFU/g，而81%的样本中乳酸菌数量超过10 CFU/g。13%的样本中检出金黄色葡萄球菌，11%的样本中检出蜡样芽孢杆菌，3%的样本中检出大肠杆菌，含量均为10 CFU/g。在6个样本中检出小肠结肠炎耶尔森菌，而在所有检测的25 g样本中均未检出沙门氏菌。许多（69%）样本的酵母菌计数高于10 CFU/g。白吉利丝孢酵母是最常见的酵母种类。除了明显代表负责发酵的霉菌种类的米根霉和少孢根霉外，印度毛霉也经常与豆豉的真菌区系相关联。讨论了微生物质量差的原因并提出了一些建议。
