what happens to starch during moist cooking?
Starch, a complex carbohydrate, undergoes a series of transformations when subjected to moist cooking methods. Initially, the starch granules absorb water, causing them to swell and soften. As the temperature increases, the starch gelatinizes, a process in which the granules rupture and release their contents into the surrounding liquid. This results in a thickening of the cooking medium and a change in texture, becoming more viscous and smooth. Additionally, the gelatinized starch molecules become more susceptible to enzymatic breakdown, leading to the further breakdown of complex carbohydrates into simpler sugars. This process, known as amylolysis, contributes to the development of flavors and aromas associated with cooked starchy foods. During moist cooking, starch also undergoes a retrogradation process, where the gelatinized starch molecules reassociate and form new, more ordered structures. This retrogradation can lead to a change in texture, with the cooked starch becoming firmer and less tender over time.
which starch is best?
