Naturally occurring pectin is a soluble fiber found in many fruits and plants. Pectin is a great example of a natural polymer, and is composed of pectic acid and pectinic acid molecules.

Every plant contains some amount, sometimes just a very small amount, of pectin.
Pectin: Not Just For Jelly. Pectin is probably most recognizable to home cooks as the ingredient that thickens jellies and jams and gives them that smooth, sticky texture. Pectin is an indigestible soluble fiber which, when combined with water, forms a colloidal system and gels. It has a wide range of uses. It can be found as a gelling, thickening or stabilizing additive in food, an ingredient in laxatives, a demulcent in throat lozenges, and vegetable glue for cigars.
