Abstract:

The preparation parameters of porous starch were optimized by single-factor, partial-factor and response surface experiments. Results indicated that the optimal preparation parameters were reaction temperature of 51.92 ℃, reaction time of 13.15 h, enzyme addition amount of 4.20%, starch concentration (V/V) 14.24%, reaction pH of 4.4 and glucoamylase-amylase ratio of 4:1. Under these optimal conditions, the water-absorbing capacity of porous starch was 156.01%.

Key words: starch, porous starch, response surface methodology
