Properties of corn and wheat starch phosphates obtained from granules segregated according to their size

Corn and wheat starches were segregated into big and small granules. Unsegregated starches and their fractions were phosphorylated with sodium trimetaphosphate. Due to applied modification method, the highest amount of phosphorus was incorporated to small granule fraction of corn starch. The least of the phosphorus was bound by small granule fraction of wheat starch. It was also shown that obtained preparations were characterised by different physico-chemical properties.
