Popis: Aims: Kerandang (Canavalia virosa) beans are good source of protein, yet predominantly kerandang foods are not widely accepted mainly because of their beany flavour the belief that they cause flatulence. The objectives of this research were to evaluate of viability of lactic acid bacteria from Indonesia indigenous fermented food in kerandang milk and its ability to metabolize indigestible oligossacharide raffinose.Methodology and results: Two strains of Indonesia indigenous lactic acid bacteria (LAB), namely Lactobacillus plantarum-pentosus T14 and Lactobacillus plantarum-pentosus T35 were used for fermentation of kerandang milk. The results showed that all strains of lactic acid bacteria possess the ability to grow and produce of lactic acid in kerandang milk, indicated that total acid (TA) increase, pH decrease and their counts of LAB increase during fermentation period (0-24 h). The two strains of lactic acid bacteria were also able to metabolize raffinose into simple sugar (sucrose, glucose, fructose and galactose) during fermentation at 37 °C, however the raffinose transformation by L. plantarum-pentosus T14 more ability than L. plantarum-pentosus T35. The metabolism of raffinose during fermentation by L. plantarum-pentosus T14 and L. plantarum-pentosus T35 were 98.23% and 48.98%, respectively.Conclusion, significance and impact of study: Kerandang milk fermented by lactic acid bacteria can decrease of saccharide raffinose cause of flatulence. Thus, lactic fermented of kerandang milk be safer for consumption.
