Colorless to light brown powder of pectin is derived from citrus fruits or apples. Pectin from citrus peel is a galacturonic-rich polysaccharide used as a gelling agent, filler, and stabilizer. Pectin, a type of complex carbohydrate found in the cell walls of land plants, serves as a valuable material for identifying, distinguishing, and characterizing pectinase enzymes. Pectin also acts as a resource for investigating the breakdown of pectin by pectinolytic bacteria.
