Abstract

Introduction: They are involved in free radicals by causing oxidative stress in chronic diseases such as cancer, atherosclerosis, and diabetes and also in the aging process. Antioxidants are the best way to fight free radicals. Plants are rich sources of natural antioxidants and Total phenolic. Objective: This study was designed to measure the amount of total phenol and antioxidant activity of malt beverages in Tehran market. Methods: In this study, 123 samples of non-alcoholic beer in Tehran market (Domestic and Imported) were prepared. Antioxidant activity was measured by FRAP (Ferric Reducing Ability of Plasma) method and Total phenolic content was measured by Folin reagent and by spectrophotometer. The standard concentration of Total phenolic compounds was measured using the gallic acid standard curve. Results: The highest content of total antioxidants and total phenols in sample No. 2 were 4. 29 µ g /ml and 5. 80 µ g /ml, respectively. The lowest content of total antioxidants and total phenol in sample No. 6 were 1. 33 µ g / ml and 1. 19 µ g/ml, respectively. There was a significant difference between the amount of total phenol and total antioxidant capacity in Domestic and Imported samples and had a higher antioxidant content of Imported samples. Which was related to the malting process and the raw materials used. The Total phenolic content of Domestic malted drinks and Imported malted drinks were in the range of 1. 10-4. 18 μ M and 1. 58-4. 33 μ M, respectively. But there was no significant difference between the two groups in terms of antioxidant content. It was observed that the content of total phenol and total antioxidants in classical malted drinks was higher than malted drinks with different flavors. Discussion and Conclusion: The results show that classic malted drinks are a potential source of antioxidants and total phenols.
