Red dragon fruit-soy protein isolate biofilm: UV-blocking, antioxidant & improved mechanical properties for sustainable food packaging.

Unlabelled: In this study, an active biofilm was developed by incorporating red dragon fruit peel (RDF) extract into soy protein isolate (SPI) film matrix for sustainable food packaging. The addition of betalain-rich-RDF extract (1-7 wt%) significantly improved UV-blocking and antioxidant properties of the film compared to the control film. As wt% of RDF-extract increased, water vapor permeability, water solubility, and elongation at break decreased by 1.

Microwave-assisted deep eutectic solvent extraction of phenolic antioxidants from onion ( L.) peel: a Box-Behnken design approach for optimization.

Valorization of onion peel waste, considered to be a rich source of polyphenolic compounds, by employing green extraction techniques is the need of the hour. The aim of the present study was to optimize the microwave-assisted extraction of bioactive phenolic compounds from onion peel wastes employing ChCl:Urea:HO deep eutectic solvent. Microwave power (100-200-300 W), time (5-15-25 min) and liquid to solid ratio (40:1-50:1-60:1) were studied as the major parameters affecting the extraction efficiency.

Microwave-assisted extraction for recovery of polyphenolic antioxidants from ripe mango ( L.) peel using lactic acid/sodium acetate deep eutectic mixtures.

The present study investigates recovery of polyphenolic compounds from ripe mango ( L.) peel using deep eutectic solvents based on microwave-assisted extraction method. Lactic acid/sodium acetate/water (3:1:4) screened out from eight different types of deep eutectic solvent systems was used as extractant.

Deep eutectic solvent-based extraction of polyphenolic antioxidants from onion (Allium cepa L.) peel.

Background: Biomass waste, including fruit and vegetable residues, poses a serious challenge to the environment. This demands novel approaches for handling and disposing of it in a safe manner. However, such waste is extremely rich in bioactive components, which are considered to have a beneficial impact on health.
