dc.description.abstractStarches with different amylose (AM)/amylopectin (AP) ratios (waxy potato: WxPS; regular potato: PS; high AM corn: HACS) are hydroxypropylated (HP, two levels) and subsequently acid‐thinned (AT) to produce dual‐modified samples. The physicochemical characteristics and techno‐functional properties of the solutions are investigated, and the data are evaluated statistically (analysis of variance). Differential scanning calorimetry gelatinization experiments reveal a reduction of the transition temperatures particularly due to HP. The subsequent AT decreases the specific enthalpy significantly. HACS samples have lower solubility (S) compared to their potato‐based counterparts (WxPS and PS), but HP enhances the starch's S. The S of the AP of the HACS samples is comparatively high, and HP particularly facilitates the additional solubilization of AM. Dual‐modified samples show characteristics of S similar to the corresponding HP samples. Or particular note, the HP‐modified WxPS and PS, respectively, tend to cause molecular degradation of the polymers dissolved. The hot paste viscosity is impacted significantly by all varied factors.en
