When foods containing starch are cooked, the heat can break the glycosidic bonds linking the glucose units together and effectively break-up the polysaccharides to release the glucose monosaccharides. This imparts a natural sweetness to the cooked food.
Why is starch important in cooking?

What does boiling do to starch?
When starch is heated with water, the starch granules swell and burst, causing them to break down and release the glucose molecules into the water. Consequently, the starch molecules interact with more water, increasing the randomness of the solution. This process is known as gelatinization.
What is the result of Ungelatinized starch?
Gelatinized starch, when cooled for a long enough period (hours or days), will thicken (or gel) and rearrange itself again to a more crystalline structure; this process is called retrogradation. During cooling, starch molecules gradually aggregate to form a gel.
What is the cooking effect on wet starch?
In our study, cooking decreased starch content, increased sugar content especially reducing sugars and therefore increased sweetness. This is expected since starch is degraded by enzymes and transformed into soluble sugars during cooking processes [27–29].
