WebbGelatin is a protein that can hold a LOT of water to form a gel. Starch can also do that, but must first be gelatinized. The gelatinization process blows apart the native starch granule that is effectively insoluble. It then becomes a giant, water holding molecule afterwards. It can form a firm gel at 1% by weight in water. Harpreet Kour WebbThe most common examples of starch gelatinization are found in sauce and pasta preparations and baked goods. How do amylose and amylopectin affect thickening? Generally speaking, the amylose gives you the gel strength and the amylopectin gives you high viscosity, says Abbas.
