Distribution In Nature

The percentage of pectic substances in plants varies with species, variety, anatomy, and maturity. The highest concentrations of pectic substances are found in young tissue and in fruit tissue. Typically, whole mature fruit contains 3 to 7% pectic substances on a dry-weight basis and 0.13 to 1.1% on a fresh-weight basis. The relative high pectic and low caloric content of citrus fruits make them a good source of soluble dietary fiber in that pectic substances are not digested until they reach the lower gastrointestinal tract. Apple pomace (the residue of pressed apples) may contain up to 20% pectic substances, and the albedo of oranges (the white, spongy material on the inside of the peel) may contain 40% or more pectic substances on a dry-weight basis.
