Effect of Phosphate on Gelatinization of Rice Starch

Abstract
|
|
|
|
Effect of phosphate (sodium polyphosphate 85%, sodium hexametaphosphate 7% and potassium phosphate 7%) on gelatinization of nonwaxy and waxy rice starches was investigated with X-ray diffractometry. The minimum moisture content for the gelatinization of nonwaxy starches was lowered in the presence of phosphate. The minimum temperature for the gelatinization of 5% starch suspensions was not altered by phosphate, However, the degree of gelatinization of rice starches at the same temperature was higher in the presence of phosphate, except waxy rice starch.
