Apple Pectin is classified as a soluble fiber which is found in most plants, but is most concentrated in citrus fruits (oranges, lemons, grapefruits) and apples. Apple Pectin is obtained by the aqueous extraction of citric peel and apple pulp under mildly acidic conditions. It appears to have hypocholesterolemic effects and may be antiatherogenic in some. Apple Pectin's adsorbent and bulk-forming properties have promoted its use in some multi-ingredient anticonstipation and antidiarrheal preparations.
As a dietary fiber, Apple Pectin is helpful in maintaining good digestive health. Fruits rich in Apple Pectin include the peach, apple, currant, and plum. Protopectin, present in unripe fruits, is converted to pectin as the fruit ripens. Pectin forms a colloidal solution in water and gels on cooling. When fruits are cooked with the correct amount of sugar, and when the acidity is optimum and the amount of pectin present is sufficient, jams and jellies can be made. In overripe fruits, the pectin becomes pectic acid, which does not form jelly with sugar solutions. An indigestible, soluble fiber, Apple Pectin is a general intestinal regulator that is used in many medicinal preparations, especially as an anti-diarrhea agent. Apples are rich in pectin, a soluble fiber, which is effective in lowering cholesterol levels.
Researchers at the University of California, Davis, found that Apple Pectin also acts as an antioxidant against the damaging portion of cholesterol in the blood stream. Many researchers suggest that people who eat fatty foods should, if possible, wash down this food with apple juice rather than the usual drink. It has been established that a diet rich in Apple Pectin may help protect against certain diseases. One of the researches in Japan has supported that Apple Pectin can also decrease the chances of colon cancer. Apple Pectin helps maintain intestinal balance by cleansing the intestinal tract with its soluble and insoluble fibers. It tends to increase acidity in the large intestines and is advocated for those suffering from ulcer or colitis and for regulating blood pressure. It is also effective in causing regressions in and preventing gallstones.
