| dc.description | Several studies have shown the antimicrobial and antioxidant properties of turmeric (Curcuma longa) , widely used in food industry as a colorant, among other functions. The aim of this study was to determine the antioxidant and antimicrobial properties of turmeric essential oil against pathogenic bacteria and to study the influence of the addition of ascorbic acid on the prevention of polyphenols oxidation. The commercial turmeric essential oil alone did not show bactericidal activity against the microorganisms studied, Listeria monocytogenes and Salmonella typhimurium , but when combined with ascorbic acid, it showed significant antibacterial activity. The highest antimicrobial activity of turmeric essential oil against Salmonella typhimurium was 15.0 ± 1.41 mm at the concentration of 2.30 mg.mL –1 of essential oil and 2.0 mg.mL –1 of ascorbic acid. With regard to Listeria monocytogenes , the largest zone of inhibition (13.7 ± 0.58 mm) was obtained at the same concentrations. The essential oil showed antioxidant activity of EC 50 = 2094.172 μg.mL –1 for the DPPH radical scavenging method and 29% under the concentration of 1.667 mg.mL –1 for the b –carotene bleaching method. | |
