The effects of PURE-DENT® and SPRESS® starch properties on their compression behavior was characterized using “SM2” approach (structural properties, macroscopic properties, and multivariate
analysis). Moisture sorption rate constants, moisture content, amylose and amylopectin degradation enthalpy, percent crystallinity, amylose–amylopectin ratio, and cross-linking degree were used
to profile starch structural properties.
