Gelatinization and retrogradation
WebJun 15, 2024 · This study investigated the changes in gelatinization and retrogradation properties of low- and high-amylose reconstituted rice flour (RRF) added with different fractions of proteins extracted ... WebApr 12, 2024 · The gelatinization temperature of rice starch increases with the number of long amylopectin chains present and becomes more challenging to gelatinize. The retrogradation degree and retrogradation enthalpy rise concurrently, the rice hardens after cooling, and this is not advantageous for the enhancement of rice flavor quality.

Amylose may act as the core of amylopectin recrystallization, facilitating the retrogradation (Zhu & Liu, 2024). Longer inner chain length could result in higher level of amylopectin recrystallization (Zhu & Liu, 2024).
WebIf gelatinized starch is allowed to stand, aggregation and rearrangement of the amylopectin in the swollen starch granules will proceed, causing the granules to harden. This phenomenon is called retrogradation of starch. As retrogradation proceeds, foods generally become hard and their food texture deteriorates. WebSep 1, 2014 · The rare sugar D-psicose was shown to have an ability to promote gelatinization of rice flour and to retard its retrogradation.

WebRetrogradation is a reaction that takes place when the amylose and amylopectin chains in cooked, gelatinized starch realign themselves as the cooked starch cools. [1] When native starch is heated and dissolved in water, the crystalline structure of amylose and amylopectin molecules is lost and they hydrate to form a viscous solution.
