Why does Gelatinisation occur?
The starch released into the liquid causes it to thicken. Gelatinisation is complete when the liquid reaches around 96C.

The starch released into the liquid causes it to thicken. Gelatinisation is complete when the liquid reaches around 96C. Recap: the process of gelatinisation occurs when starch granules are heated in a liquid, causing them to swell and burst, which results in the liquid thickening.Click to see full answer. Besides, what causes gelatinization?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. Water acts as a plasticizer.Secondly, what is gelatinization in cooking? Gelatinization in cooking refers to the gelatinization of starch in which starch granules swell when heated in the presence of water. Prolonged heat and stirring (or pressure such as in making popcorn) is necessary to completely dissolve the starch granules. Likewise, what does Gelatinisation mean? Gelatinisation is a chemical reaction involving starch, moisture and heat. The definition of gelatinisation is: the thickening of starch in the presence of moisture and heat. It turns a colloidal system from a temporary suspension to a permanent suspension.What foods use Gelatinisation?The most common examples of starch gelatinization are found in sauce and pasta preparations and baked goods. In sauces, starches are added to liquids, usually while heating. The starch will absorb liquid and swell, resulting in the liquid becoming thicker.
