摘要：

In this work, granular cold-water soluble waxy corn starch (N-GCWS) and granular cold-water soluble porous waxy corn starch (P-GCWS) were prepared by waxy corn starch (WS) treated with alcohol-alkali. Starch morphologies, crystal structures, turbidity, cold water viscosity, freeze-thaw stability and oil absorption capacity of N-GCWS and P-GCWS starches were compared. The results showed porous waxy corn starch (PS) was easier to prepare P-GCWS starch than WS to prepare N-GCWS. SEM showed that PS and WS became dent-twisted and tended to flatten with the increase of CWS. After alcohol-alkali treatment, the X-ray diffraction pattern of PS and WS changed from A type to amorphous and pores were remained on the surface of P-GCWS starches granular. Turbidity, freeze-thaw stability, viscosity, oil absorption capacity of N-GCWS and P-GCWS starches was shown higher than that of WS and PS. The oil absorption capacity of P-GCWS was higher than that of N-GCWS. (C) 2019 Elsevier B.V. All rights reserved.
