Pectin

Pectins are heteropolysaccharides abundant in plant cell membranes. They are polymers galacturonic acid sup-units and are acid-stable gel formers obtained by extraction from apple or citrus peels.

Pectins are available as various polygalacturonic types (high-methoxy, low-methoxy, and amidated) with specified gelling conditions, pH ranges, total solids, cation, temperature requirements, etc. The manufacturer should request detailed specifications and applications from their pectin supplier.

One of the features of using Pectin is its acid stability and ability to form gels in acidic systems, such as those containing alpha-hydroxy acids. These gels or lotions are now being marketed to improve skin texture and eliminate dead skin cells.

In addition, Pectin forms synergistic gelling systems such as those consisting of locust bean and xanthan gum, forming heat-reversible and flexible gels. It also forms films when cast as a thin layer and dried to the desired moisture content.
