Which component recognized in kelp fiber is noted for its ability to absorb water and form a gel-like substance?
Answer
Alginic acid
The significant fiber content within kelp is a major advantage for digestive wellness, comprising a substantial portion of its dry weight. This fiber includes various types, notably soluble fibers such as alginates and fucoidans. Specifically, Alginic acid is identified as a key component within this fiber profile. This acid possesses a recognized biophysical capacity to absorb substantial amounts of water. Upon hydration, it creates a viscous, gel-like substance as it moves through the digestive tract. This gelling action is beneficial because it aids in promoting regularity in bowel movements and contributes positively to feelings of satiety, which is helpful for weight management efforts.
