Abstract:

In order to establish an optimum process for preparing nutritional golden corn rich in resistant starch (RS) from corn, the effects of key conditions for autoclaving treatment, aging and dehydration on resistant starch content were studied. The results showed that the optimum preparation process was that 40% corn porridge was initially subjected to autoclaving treatment at 125 ℃ for 60 min, followed by aging at 4 ℃ for 6 h and dehydration 60 ℃ for 16 h. The RS content of the finished product prepared under such conditions was 10.5%.

Key words: corn, nutritional golden corn, resistant starch, autoclaving, processing parameters
