Antioxidant and antimicrobial capacity of encapsulated thyme essential oil in alginate and soy protein-based carriers

The aim of this study was to develop a stable hydrogel carrier system for thyme essential oil (TEO) that could protect its sensitive polyphenol compounds. impact wall material (soy protein and alginate) on encapsulation efficiency thymol release in simulated gastrointestinal conditions, investigated. ~ 80 % 20 gastric pancreatic solutions, respectively. Thyme plays an important role as antimicrobial antioxidant agent. Results indicated encapsulated TEO inside the matrix exhibited activity demonstrated by CUPRAC ABTS analysis, even after thermal treatment beads, indicating metal chelate effect dominant. In vitro has been studied against several pathogenic microorganisms such Escherichia coli, Staphylococcus aureus, Bacillus cereus Candida albicans. Beads coded Ca-A1.5/SP1.5 showed anti-Candida albicans activity, while modified bead formulations Ca-A1.5/SP1.5* Ca-A1.5/SP0.25** bactericidal coli aureus.
