Degree of crosslinking of starch
WebCrosslinking is used to render a starch stable at high temperatures, low pH, and in applications with considerable shear.[2,10] The gelatinization temperature of crosslinked starch increased as the degree of crosslinking increased. However, the enthalpy of crosslinked rice starches was not significantly changed.[11,12] The retro- WebJan 1, 2024 · Determination of degree of crosslinking. The degree of crosslinking was determined by Rapid Visco Analyzer technique (RVA) from the peak viscosity values. Briefly, aqueous dispersion of starch was heated at the heating rate of 11/min from 50 to 95 °C, maintained for 2 min, cooled down to 50 °C and held again at 50 °C.
