摘要：Arrowroot starch can be modified to produce resistant starch (RS),which have been observed to show physiological functions similar to dietary fiber.Acid hydrolysis and autoclaving-cooling cycling treatments can increase RS content.Arrowroot starch modification hydrolyzed by 1.1 and 2.2 N HCl for 0,2,4,and 6 hours,then continued with 3 cycles of autoclaving-cooling treatment.Based on the starch digestibility,the acid hydrolyzed starch by 2.2 N HCl for 2 hours and 3 cycles of autoclaving-cooling cycling treatment had the lowest digestibility (22.04%).This treatment also increased amylose,dietary fiber,and RS contents.The increase of the amylose contents contributed to increase the total dietary fiber and RS contents up to 4.1 and 4.4 times,respectively,than native starch.
