Absorption of water or hydrolysis
Heat does not affect it. It expands with coolness. It contracts with heat.
Iodine interacts with starch to form a deep blue complex, which is commonly used as a test for the presence of starch in plants. When iodine is applied to plant tissues, it binds to the amylose component of starch, indicating its presence. This reaction is often used in laboratory experiments to visualize starch storage in various parts of the plant, such as leaves and tubers. However, iodine itself does not affect the synthesis or metabolism of starch in plants.
Starch in water may occur during cooking when starch-containing foods are rinsed or soaked in water. Starch granules can release into the water due to mechanical action or heat, resulting in a cloudy appearance to the water.
The addition of peptidase to starch primarily does not have a direct effect, as peptidases are enzymes that break down peptides and proteins, not carbohydrates like starch. Instead, starch is hydrolyzed by amylase enzymes into simpler sugars. If peptidase is present in a mixture containing starch and proteins, it may enhance the overall digestion process by breaking down protein components, but it will not directly affect the starch itself.
Modified starches are starches that have been chemically or physically altered to change their properties, such as improving stability, thickening, or reducing gelatinization temperature. Examples include resistant starch (improves digestion), hydrolyzed starch (helps in quick thickening), and cross-linked starch (enhances stability and tolerance to heat and shear).
starch grains first soften, then absorbs water and swells in the presence of moist heat
Purchase a cold water swelling starch.
Starch thickens a filling. You need to use the proper amount of starch and heat it properly to bind the moisture of the pie filling and the sugar.
Yes

Yes, starch is flammable. When starch is heated to a high temperature, it can ignite and burn. It is important to avoid exposing starch to open flames or high heat sources during ironing.
Heat does not affect it. It expands with coolness. It contracts with heat.
Tapioca starch has similar properties to corn starch. The amylose content of tapioca starch is about the same as corn starch but there are some phosphate groups present in tapioca which I think affect the solubility of starches in water.
Dextrinisation is the browning process produced by dry heat on starch. The starch molecule breaks down into dextrin. An example is bread.
No, dextrinization and gelatinization are not the same. Dextrinization is the breakdown of starch molecules into smaller dextrin molecules through heat, while gelatinization is the swelling and bursting of starch granules in water, leading to the thickening of a mixture.
Yes gelatinisation does occur in pancakes. Gelatinisation is when granules absorb water and swell. It is when starch grain mix in with a liquid and heat the starch. Pancakes have starch in them and therefore gelatinisation does occur.
