Starch gelatinization wikipedia
WebbGelatinization . Swelling of starch granules due to water and heat. Gelatinization temperature: the temp at which Max. viscosity is reached. Retrodegradation. At cooling, re-association of hydrogen bonds between the molecules of amylose that are leached out. Increase in amylose content in starch – leads to Increased in viscosity WebbIn many cases, starch gelatinization is related to the PT assessed by the standard RVA method (mixing 3 g of flour into 25 mL of water). Kweon, et al. (2010) observed a better correlation between the pasting properties of flour dispersed in 50% sucrose solution with the final product than dispersed only in water.
