Abstract
Some chemical properties, anthocyanin and total phenolic content and antioxidant capacity of some rosa products namely petals, syrups, jams and leavens were determined. Antimicrobial activities of rose petals and rosa leavens were also investigated. Total dry matter, total soluble solids, ash, pH, titratable acidity, reducing
sugar, sucrose, total sugar, color (L, a, b), total phenolic content, antioxidant capacity (β-caroten bleaching method, DPPH free radical-scavenging activity (IC50), TEAC, (IC50)) of rosa petals were determined as 18.43%; 10.35%; 0.90%; 5.30; 0.99%; 4.66 g·100 g–1; 1.72 g·100 g–1; 6.38 g·100 g–1; 38.98; +17.3; –3.44; 481.54 μg GAE·mg–1 sample; 88.6%; 0.97 μg·ml–1; 9.36 μg·ml–1, respectively. Rosa petals and leavens extracts showed significant antimicrobial activity against Acinetobacter lwoffii, Bacillus cereus, Proteus mirabilis GM 2644, Staphylococcus aureus ATCC 29213, Streptococcus mutans ATCC 35668 and Yersinia enterocolitica. In rosa leaven, the sample types were found effective significantly (p < 0.01) on total dry matter, total soluble solids, ash, titratable acidity, pH; L and b values; total anthocyanin content, total phenolic content and antioxidant capacity. In rosa syrup, the sample types were found effective significantly (p < 0.01) on total dry matter, total soluble solids, pH, titratable acidity, L, a, b, total phenolic content and antioxidant capacity. In rosa jam, the sample types were found effective significantly (p < 0.01) on total dry matter, total soluble solids, ash, titratable acidity, pH, total sugar, sucrose, reducing sugar, HMF, a value, total phenolic content and antioxidant capacity.
