In this study, flour of wheat cultivar Yangmai 158 was used as the raw material for investigating the optimal separation process of A- and B-type starch granules in it using response surface methodology. A series of D-optimal response surface design experiments was carried out, and the experimental data were fit by a mathematical regression model for the difference between maximum particle size of B-type starch granules and minimum particle size of A-type starch granules (Bmax-Amin) as a function of 4 independent variables (i.e. temperature, sedimentation time, wheat flour suspension volume and sedimentation number). Results revealed that a maximum Bmax-Amin value was obtained using the optimum sedimentation process of 9 replicate sedimentation for 12.84 mL of suspension volume at 21.3 ℃ for 0.96 h each time.

Key words: A- and B-type starch granules, response surface methodology
