BackgroundPectin (E?440) a naturally occurring complex heteropolysaccharide found in the cell wall and middle lamella of plants is widely used as a hydrocolloid, stabilizer, emulsifier, encapsulant, and gelling agent in foods. In addition, pectin is also a promising nutraceutical ingredient for drug delivery and formation of nanoemulsion. The unique structure of pectins is due to the presence of various hydroxyl and carboxyl groups along its backbone which enables for easy modification and functionalization with various bioactive compounds. Functionalization of the pectin for enhancing antimicrobial properties and its application in active packaging films is the current area of research.
