- •
Alkaline cooked pericarp and endosperm was compared with starch and cellulose.
- •
XANES indicates similarities between pericarp-cellulose and endosperm-starch.
- •
CaCO3 is the main species as demonstrated by EXAFS data from cellulose and starch.
- •
Calcium binds preferably to the pericarp hemicelluloses.
- •
Calcium could be forming Ca-protein species within the endosperm starch granules.
