Obtaining a biopolymer from orange peel waste

Abstract

In the following work, a formulation based on pectin obtained from orange peels as a natural polymer was proposed, on which the drying and agitation times were varied until a film with the desired characteristics was obtained. For the correct achievement of the film characteristics, compounds such as glycerol and sodium alginate were added, which provided improvements in the physical properties of the films. After finding the appropriate times to obtain the desired film, several tests were carried out to determine the physical and chemical properties of the films, including: determination of thickness, biodegradability in soil, water vapor permeability, moisture content and swelling behavior.
