| Summary: | The family of Piperaceae contains the species P. cubeba L., which has been used as a
spice in countries such as Malaysia, Indonesia, India, Morocco, and Europe. A previous
study has shown that crude extracts of tailed pepper (P. cubeba L.) have antimicrobial
activities against foodborne pathogens species. The excellent antimicrobial activity of P.
cubeba L. berries extract makes it suitable for use as a natural preservative or sanitizer in
the food. The aim of this study was to evaluate the effect of the P. cubeba L. berries
extract on microbial population in tofu. The tofu samples were cut into small pieces and
mixed thoroughly to ensure the homogeneity of natural microflora. Ten grams of the
samples were immersed in 20 mL varying concentrations of P. cubeba L. extract; 0.00%,
0.05%, 0.50% and 5.00% for 1, 2 and 4 hrs at room temperature (23±2°C) with the
agitation of 50 rpm. At 1, 2 and 4 hrs the numbers of total plate count (TPC), Bacillus
cereus, coliform and Escherichia coli were counted. The result shows that a reduction of
at least 3 Log10 CFU/g of TPC, Bacillus cereus., coliform and E. coli in tofu samples was
observed when the samples were treated with 0.50% extract for four hours. The result
suggested that P. cubeba L. berries extract can be used as a natural preservative to reduce
the microbial load in raw food. |
