Citric Acid‐Crosslinked Chitosan Coatings Incorporating Curcumin for Enhancement of Antioxidant and Antimicrobial Properties

open access: yesJournal of Vinyl and Additive Technology, EarlyView.
A fully bio‐based coating was developed using Chitosan, Citric acid, and Curcumin. Citric acid acts simultaneously as a green solvent and non‐toxic crosslinker. Dry Heat Treatment enhances water resistance and thermal stability, creating an active packaging system with dual antioxidant and antimicrobial properties to extend food shelf‐life.

Preparation and characterization of flurbiprofen-loaded poly(3-hydroxybutyrate-co-3-hydroxyvalerate) microspheres [PDF]

open access: yesJournal of Microencapsulation, 2008
Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) microspheres containing flurbiprofen were prepared by an oil-in-water emulsion solvent evaporation method, in order to develop a particulate drug delivery system for localized administration. A response surface method (RSM) using a central composite design was employed to evaluate the effect of the ...
