| Abstract | Roselle is an herbaceous medicinal plant where being native in Asia. The calyx of roselle action as well as its bioactive compounds and natural pigments. In this work, total phenolic, total flavonoid, scavenging capacity and antibacterial activity of roselle aqueous extract were investigated and applied as substrate for wine production. Scavenging capacity of roselle aqueous extracts were increased dependently on dose of total phenolic compound in extract. Roselle wine was produced and evaluated on pH, alcohol (%), total acid (%), total solid (oBrix), total viable count of bacteria and yeast/mold for 10 days of fermentation. pH and total solid were significantly decreased from 0 day of fermentation, while alcohol, total acid and total viable count of bacteria and yeast/mold were significantly increased until the end of process. Roselle aqueous extract at the concentration of 0.5 and 1 mg/ml were inhibited the growth of Escherichia coli, Salmonella sp., Bacillus sp. and Staphylococcus aureus while wine product have no effect on antibacterial activity. |
