Preparation of new active edible nanobiocomposite containing cinnamon nanoemulsion and pectin

Abstract

In this study, the objective was to produce biodegradable nanobiocomposites based on pectin and cinnamon nanoemulsion having satisfactory properties for application as active packaging. Procedures for preparing and incorporating these nanoemulsions in the polymeric matrix are described. The nanocomposites were analyzed through: thickness measurements, solubility, mechanical properties and scanning electron microscopy (SEM). A subjective analysis indicated the nanocomposite made with pectin 2% w/v and nanoemulsions prepared with stirring speed of 16000 rpm in 2 min was the most suitable for application in packaging. The nanocomposites containing nanoemulsions with smaller nanodroplets had greater strength and elongation, being less soluble. The control of these properties by varying the average size of the nanoemulsion makes these materials potentially viable, for example, for active packaging.
