Product Overview
Pectin is a complex carbohydrate found in the cell walls of fruits. It is valued for its ability to form gels when combined with sugar and acid, making it essential in the production of jams, jellies, marmalades, and fruit preserves. Beyond food, pectin also finds applications in pharmaceuticals and cosmetics as a stabilizer and emulsifier.
