Mechanism of gelatinization

WebApr 13, 2024 · Gelatinization occurs in three steps as starch granule swelling, melting, and amylose leaching. During heating, swelling occurs due to the absorption of water into the amorphous space of starch. Then … WebJan 12, 2024 · The gelatinization parameters of the YS-SPI complexes are summarized in Table 1. The peak temperature (T p1) of the yam starch changed slightly with the addition of the soy protein isolate. It may be that the integrity of the starch granules was more severely disrupted by the addition of soybean isolate and extrusion, and the interaction ...

Difference Between Gelatinization and Gelation

WebGelatinization is the irreversible process with respect to the shape of starch molecules. Oppositely, retrogradation is the reversible process in which the solubilized starch chains realign, forming hydrogen bonds by expelling water to form a more crystalline structure. WebOct 16, 2013 · Starch gelatinization is the process where starch and water are subjected to heat causing the starch granules to swell. As a result, the water is gradually absorbed in an irreversible manner.

Starch gelatinization is a process of breaking down of intermolecular bonds of starch molecules in the presence of water and heat, allowing the hydrogen bonding sites (the hydroxyl hydrogen and oxygen) to engage more water. This irreversibly dissolves the starch granule in water. Water does act as a plasticizer. Three main processes happen to the starch granule: granule swelling, crystallite or double helica…
