WebGelatinization of polysaccharides is controlled by the water content, therefore when food high in starches (rice, pasta, etc.) is cooked the outer layers of the food will heat much faster than the inner layers. 24 This is because the inside of the food is in an area of low hydration and cannot gelatinize as quickly. 24 As a result, Fukuoka et al. … WebBarley malt starches gelatinize at temperatures between 61°C and 65°C (142°F and 149°F). Most adjunct starches, such as corn grits or rice, require higher temperatures for gelatinization and are therefore cooked separately before being added to the mash for saccharification. See cereal cooker.
