Abstract
The microstructure of rice starch and dextran-rice starch mixtures was studied using confocal laser scanning microscopy (CSLM) and scanning electron microscopy (SEM). Surface pores and channels of rice starch were looked for. Channels could not be found in rice starch granules after reaction with 3-(4-carboxybenzoyl)-quinoline-2-carboxaldehyde (CBQCA). Fluorescein-labeled dextran was mixed with rice starch in order to locate hydrocolloid molecules in hydrocolloid-rice starch mixtures. The results showed that FITC-dextran (ave. Mw 4000; FD4) penetrated into raw rice starch granules, with the degree of penetration varying from granule to granule. FD4 could penetrate throughout cooked rice starch granules. FITC-dextran with an average Mw of more than 10,000 could not penetrate either raw or cooked rice starch granules. © 2011 Elsevier Ltd. All Rights Reserved.
