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

Abstract

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

Feasibility of production starch/poly(butylene adipate‐co‐terephthalate) biodegradable materials with microalgal biomass by blown film extrusion

“…The elastic modulus of the films ranged from 34.04 to 37.06 MPa (Table 6). These results were similarly obtained by Mücke et al (2021) on TPS/PBAT films, where Young's module was 33.47–37.19 MPa. All the films had similar and low rigidity, characteristic of plastic films, and the microalgae biomass did not affect this property.…”

“…Also, Garcia et al (2014) The elastic modulus of the films ranged from 34.04 to 37.06 MPa (Table 6). These results were similarly obtained by Mücke et al (2021) on TPS/PBAT films, where Young's module was 33.47-37.19 MPa.…”

“…Studies of its mixture with biodegradable polyesters are a strategy to improve packaging materials' mechanical and barrier properties (Garcia et al, 2018). Thus, blends with poly(butylene adipate‐ co ‐terephthalate) (PBAT; Balan et al, 2021; Mücke et al, 2021; Müller et al, 2020), poly(lactic acid) (PLA) (Mangaraj et al, 2019), and poly(vinyl alcohol) (Javed et al, 2016), among others, have been studied.…”

Curcumin Alleviates LPS-Induced Oxidative Stress, Inflammation and Apoptosis in Bovine Mammary Epithelial Cells via the NFE2L2 Signaling Pathway

“…Secondly, its metabolism in the organism intestine and liver is very fast [54]. At present, the use of polymer synthesis technology to prepare amphiphilic polycurcumin block copolymers with CUR as a comonomer has overcome the shortcomings of CUR in water solubility and poor stability [55][56][57]. Although low-dose CUR can protect MAC-T cells from LPS damage in our research results, if you want to use it in animal husbandry production A new in vivo experiment is needed to determine the most suitable CUR dosage.…”
