Özet
The aim of the present study was to determine the effect of essential oils on antioxidant and antimicrobial properties of collagen hydrolysate. The essential oils were obtained from Laurus nobilis L. (3,7%) and Thymbra spicata L. (4,1%) and they were characterized by GC-MS. Collagen hydrolysate obtained by biotechnological process was modified by essential oils and hydroalcoholic solutions with 0.25, 0.50, 1.0 and 2.0% thymbra and laurel oil were prepared. These hydroalcoholic solutions were characterized by antioxidant activity and antimicrobial activity against Escherichia coli. The antioxidant activity was more effective for the combination between hydrolysate and essential oils and increased with essential oils concentration increase. Based on its properties the hydroalcoholic solution with collagen hydrolysate and 2% thymbra oil proved the best antioxidant and antimicrobial activity in order to be use in medical, pharmaceutical, cosmetic, biotechnology and food industry. © 2012 University of Bucharest.
