General description

Pectin is a polysaccharide is rich in galacturonic acid and possesses a complex structure and function.

Application

Pectin from citrus peel has been used:
  • in the comparative study of physicochemical, rheological and gelling properties of pectin among different extraction method
  • in starch suspension for measuring in vitro starch digestibility
  • to measure pectinase activity
  • in the production of pectinase on solid medium

Biochem/physiol Actions

Pectin is essential for plant development including growth, morphological changes and immunity. It serves as a stabilizing polymer and is useful in food and speciality products.
Pectin, a heterosaccharide component of terrestrial plant cell walls, is used as a substrate to identify, differentiate and characterized pectinase(s). Pectin is used to study its degradation by pectinolytic bacteria.
