Abstract

Background and purpose: Nowadays, adding natural preservatives is one of the main methods for increasing shelf-life. This study evaluated the antioxidant activity of Zataria multiflora hydroalcoholic extract and its antibacterial effect on Staphylococcus aureus in hamburger. Materials and methods: In this experimental study, after collection and extraction of Zataria multiflora, total amount of phenols and flavonoids as well as flavonols were colorimetrically determined. The antioxidant activity was evaluated by β-Carotene bleaching assey. Then the effect of different concentrations of Zataria multiflora extract (0.0, 0.5 and 1.5) in 4±1°C at different storage times (0, 1, 3, 6, 9 and 12 days) was evaluated on growth of Staphylococcus aureus in hamburger. Results: Total phenol content in Zataria multiflora extract was 283.43±11.06 mg/gr as gallic acid equivalent. Total flavonoid and total flavonol contents were 131.23±4.5 and 92±5.67mg/g as rutin equivalent, respectively. Antioxidant activity was 71±4 percent. Also Zataria multiflora extract in 4±1°C decreased the growth rate of Staphylococcus aureus in hamburger. Conclusion: These findings showed that Zataria multiflora had antibacterial effect and could be used as an antibacterial preservative in hamburger or other meat products.
