RS2 – Resistant starch is inaccessible to enzymes due to starch conformation, as in green bananas, raw potatoes, and high amylose corn starch. RS3 – Resistant starch that is formed when starch-containing foods (e.g. rice, potatoes, pasta) are cooked and cooled.
Because the long linear chains of amylose more readily crystallize than amylopectin (which has short, highly branched chains), high-amylose starch is more resistant to digestion. [8] Unlike amylopectin, amylose is insoluble in water. [9] [10] It also reduces the crystallinity of amylopectin and how easily water can infiltrate the starch. [6]
Resistant starch is starch that escapes digestion in the small intestine of healthy individuals. High-amylose starch from wheat or corn has a higher gelatinization temperature than other types of starch, and retains its resistant starch content through baking, mild extrusion and other food processing techniques.
A study review published in Frontiers in Nutrition showed that resistant starch types 1 and 2 (1 is found in whole foods, 2 in some supplements like corn-based resistant starch supplements) can ...
Retrograded starch is a type of resistant starch. Chemical modification of starches can reduce or enhance the retrogradation. Waxy, high amylopectin, starches also have much less of a tendency to retrogradate. Additives such as fat, glucose, sodium nitrate and emulsifier can reduce retrogradation of starch.

Besides carbs being a crucial source of energy, potato skin provides a fiber called “resistant starch,” which has been shown to improve blood sugar control, help you feel satiated and lower ...
Resistant starch has another neat trick: Research reveals it may also help lower cholesterol. And while we often hear how important it is to eat the rainbow, don’t underestimate monochrome ...
Damaged starch can be produced, for example, during the wheat milling process, or when drying the starch cake in a starch plant. [5] There is an inverse correlation between gelatinization temperature and glycemic index. [4] High amylose starches require more energy to break up bonds to gelatinize into starch molecules.
