Kualitas Mikrobiologis Salami Probiotik yang Difermentasi oleh Kombinasi Kultur Lactobacillus sp 1A5 dan Lactobacillus fermentum 2B2 Selama Penyimpanan Dingin

Abstract

Probiotic Salami is one of functional foods which is made from meat, it is fermented by starter culture of lactic acid bacteria. The lactic acid bacteria were used as starter has potential as probiotic. The probiotic bacteria will guard microflora balancing in our gastrointestinal. The aim of this research was to evaluate microbiological quality of probiotic salami produced from mixed culture of Lactobacillus sp 1A5 dan Lactobacillus fermentum 2B2. The randomized complete design with three times replication was used as experimental design. The treatments were storage at low temperature 10o ± 2o C for 0-day after conditioning process, 10- day, 20-day, and 30 day. The variables were total lactic acid bacteria, total plate count, quantitative of Staphylococcus aureus, quantitative of Escherichia coli. The result of this research showed that the decreasing quantitative of Staphylococcus aureus and quantitative of Escherichia coli were not significantly (P > 0,05) effected during cold storage. There was significant decreasing (P < 0,05) from total lactic acid bacteria and total plate count during cold storage. The significant effect of the total lactic acid bacteria occurred at 20-day and total plate count were at 30-day. Keywords : Salami, probiotic, storage, microbiological
