  This study aimed to evaluate the properties of RS 3 prebiotic from modified arrowroot starch, a result of in-vitro combination of acid, enzymatic and physical modification. Arrowroot starch resulting from combination between acid hydrolysis (2.2 N HCl, 2 hrs), debranching using enzymes pulullanase (10.4 U/g starch), 3 cycles of autoclaving-cooling (121ºC, 15 min), and heat moisture treatment (121ºC, 1 hr), has increased level of resistant starch. The evaluation of the prebiotic properties of RS 3 in modified arrowroot starch was performed in vitro. Modified arrowroot starch from a combination of hydrolysis acid (AH), debranching (D), and autoclaving-cooling (AC) and combinations of acid hydrolysis, debranching, autoclaving-cooling, and heat moisture treatment (AHDAC-HMT) modification process had the highest resistance to artificial gastric acid a..
