Findings of the paper reveal that the natural dyes extracted out of the agri-food industry waste, can be a sustainable alternative to synthetic dyes in developing countries
The recovery of phenols was dependent on the solvent system used. Solvent mixtures have been shown to extract significantly larger amounts of crude material from pepper wastes than the neat solvents
The most efficient solvents for extracting phenols and flavonoids from pepper waste, was around (65–35–0%) for, respectively, acetone–water–ethanol.
Then a study was undertaken to evaluate the antimicrobial activity of the extract in solution and dyed wool samples against P. aeruginosa and S. aureus
The observed antimicrobial characteristics indicate that the dye might be a promising antimicrobial agent for developing bioactive textile materials and clothing.
