Abstract:
Etawa goat milk is the name for dairy products from a hybrid goat named Etawa. In Indonesia, goat milk is usually marketed and consumed fresh, without proper sterilization in the production process. As a raw product, Etawa goat milk has the potential to be contaminated with various microbes. In order to improve the microbial quality of Etawa's raw milk, we conducted a study aimed to evaluate the effect of adding aqueous extract of Roselle flower Hibiscus sabdarrifa L on the milk content of bacteria. Five groups of fresh milk samples, each 25 ml, were given roselle flower extract sequentially of 0.5 ml, 1.0 ml, 1.5 ml, 2.0 ml and 2.5 ml with a repetition of 5 times. Before adding the extract, the type of bacteria identified was Escherichia coli, Lactobacillus sp, and Staphylococcus sp with a total bacterial content of 1,569,586 CFU/ml. After adding extracts of 0.5 ml, 1 ml, 1.5 ml, 2 ml, and 2.2 ml, the total number of bacteria decreased to 1,078,660 CFU/ml, 1,010,423 CFU/ml, 938,602 CFU/ml, 882,.873 CFU/ml, and 874,238 CFU/ml respectively. Thus it can be concluded that roselle flower extract has the potential to be used as an ingredient to improve the microbial quality of fresh milk of Etawa goats.
