Use of Water-Soluble Curcumin in TPS/PBAT Packaging Material: Interference on Reactive Extrusion and Oxidative Stability of Chia Oil

The reactive extrusion technique is efficient in the incorporation of bioactive compounds for active packaging development. application curcumin, a strong antioxidant its pure, isolated form to obtain has already been investigated; however, use water-soluble curcumin (WSC) thermoplastic starch/poly(butylene adipate-co-terephthalate) (TPS/PBAT) films not yet investigated. It important determine how WSC would affect starch esterification reaction during (REx). at 0.5%wt led an increase tensile strength, elongation break, and Young’s modulus. A reduction was observed; improvement TPS/PBAT compatibility detected by infrared spectroscopy, X-ray diffraction, scanning electron microscopy images. worth noting that addition resulted film’s solubility water vapor permeability, due hydrophilic character WSC. were used package chia oil, oxidative stability data evaluated UV-Vis spectroscopy coupled with principal component analysis. (0.5%wt) oil stability, suggesting using may be promising alternative case extruded films.
