| Abstract: | The resistant starch was prepared with the High amylose corn starch by autoclaving-cooling cycles combined with acids hydrolysis treatment.The effects of concentration of starch solution,autoclaved temperature,autoclaved time and times of autoclaved-cooling cycles on the content of RS were studied in the autoclaved treatment.The type,concentration and treatment time of acids were also studied in the acid hydrolysis process.The results showed that the optimum conditions is： 30% starch solution was autoclaved at 125℃ for 45min,after repeated 2 times,0.15mol/L citric acid hydrolysised for 12h.The yield of resistant starch is up to 39.27%. |
