Abstract

This research aimed to develop ganyong starch as resistant starch (RS) which has functional properties. Two kinds of acid hydrolysis (chloride acid and citric acid) on ganyong RS. Each hydrolysis was designed as Factorial Completely Randomized Design with two factors as treatments and each treatment was repeated three times. The first factor consisted of pH 5.5; 5 and 4.5 for the HCl hydrolysis; and pH 2.6; 2.5 and 2.4 for citric acid hydrolysis, whereas the second factor was the hydrolysis time (6, 12 and 18 hours). The parameters were the amount of RS and total fiber, starch and water content, as well as the micro structures of RS with SEM. The results showed that pH and hydrolysis time had significant effect on RS, fiber, and starch but had no significant effect on water content. The starch content in the RS was affected by pH level for both HCl and citric acid hydrolysis. The SEM showed that the RS processed by citric acid was more condensed compared to HCl. The highest RS (37.019%) and fiber (53.04%) content was obtained by citric acid hydrolysis at the pH of 2.4 for 18 hours of hydrolysis, and the water content was 3.27% to 3.51%.
