Both are large +carbohydrate units consisting of glucose molecules. Amylose is a straight chain, +while amylopectin is highly branched. That structural difference leads to +differences in the texture of cooked rice. Amylose is less soluble in water, and +doesn't readily form a gel or produce a thickening effect in hot water; in +contrast, amylopectin is more water soluble, and raises the viscosity of the +surrounding water. Rice grain varieties that are relatively high in amylose tend +to be more separate when cooked, with less sticking between grains, while rice +with a higher relative amylopectin content tends to produce stickier rice with +less separation between grains. + +## Doneness: Gelatinization vs Pasting + +Rice being mostly starch, is composed of semi crystalline granules. If exposed +to enough heat and moisture, these starch granules swell and soften, loosening +that hard, crystalline structure, a process known as **gelatinization**. When +rice is fully gelatinized, it is soft and palatable; otherwise it feels crunchy +(undercooked). + +After gelatinization, continued heating or agitation begins to break down those +swollen starch granules, leaching amylose and increasing the viscosity of the +surrounding liquid. This process known as pasting results in sticky and mushy +rice (overcooked). +
