Excessive heating, however, may cause evaporation of the water and shrinkage of the gel. The most common examples of starch gelatinization are found in sauce and pasta preparations and baked goods.
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. The following molecular associations can occur: amylose-amylose, amylose-amylopectin, and amylopectin-amylopectin. A mild association amongst chains come together with water still embedded in the molecule network. WebEnter the email address you signed up with and we'll email you a reset link.
