Uses for Grapefruit Pectin

Pectin is a substance found in the cell walls of many plants and fruits, including citrus such as grapefruit. It is highly concentrated in the grapefruit's internal white peels. According to the Silpakorn University, Bangkok, the most important use of pectin is based on its ability to form gels, which can be employed in the pharmaceutical industry, as well as in the production of jams, jellies, dairy products and other foods.

Jams and Jellies

• Grapefruit and other citrus pectins were first used in the home production of jams and fruit jellies to obtain a thicker texture, reduce the formation of water during storage and guarantee an even distribution of fruit pieces. According to the International Pectin Producers Association, some European markets sell fruit pectin as a component of gelling sugar, used to make jellies and jams.

Dairy Products

• Pectin is used as a stabilizer, to prevent undesirable changes in the texture of many dairy products, including condensed milk, clotted cream, yogurts and cheese. According to the Codex Alimentarius Commission, pectin is also used in the processing and production of dried vegetables, processed fruit, breakfast cereals, precooked noodles, edible sausage casings, vinegars, mustard and other sauces, soybean products, beers and ciders.

Medicines

• Grapefruit pectin is used in many medicines as a intestinal regulator and anti-diarrhea agent, reports the Vitamins & Health Supplements Guide. Although pectin is resistant to human digestion, it can be degraded in the colon by naturally occurring bacteria. Pectin is also used to reduce blood cholesterol levels, as an anticoagulant and in the production of pellets, gel beads, coated tablets and other slow-release drug systems, according to Silpakorn University.
