Gelatinisation food tech definition
WebGelatinisation By definition Starch gelatinization is a process of breaking down the 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. WebDuring gelatinisation, the starch granules absorb water and swell, melting the internal crystalline structures that lead to the granules breaking down (Batey 2007). Pasting follows gelatinisation and involves granular swelling and leaching of * Marena Manley [email protected] 1 Department of Food Science, Stellenbosch University, Private Bag
