Abstract

Ambon banana is a highly consumed banana variety in West Java. However only the fruit flesh is consumed while the peel generally becomes waste. Banana peels are rich in indigestible carbohydrates which are known to have prebiotic activity. Several varieties of bananas have been investigated for their prebiotic activity, but research on Ambon banana is still limited. This research aims to evaluate the prebiotic activity of Ambon banana peel powder. Ambon peel powder with 1% w/v in concentration was examined for its growth stimulation effect on Lactobacillus acidophilus probiotics. SCFAs production was also analyzed using HPLC. The results showed that Ambon banana peel powder has prebiotic activity with the prebiotic activity score of 13.47. Analysis showed the presence of butyrate, propionate and acetate in the L. acidophilus culture enriched with Ambon banana peel powder. The concentration of butyrate, propionate and acetate were 7.27, 1.32 and 0.23 microgram per mL respectively. This study confirmed that Ambon banana peel powder could be an effective prebiotic in increasing the growth of the tested probiotics
