Effects of royal lotus petals on antioxidants of bael-rosella mixed herbal drink

Abstract

This research aimed to study the quantity of royal lotus petals and the antioxidant activity in the bael-rosella mixed herbal drink. The recipe of the bael-rosella mixed herbal drink included dried bael, dried rosella, sugar and water at 8.55, 0.85, 5.13 and 85.47%, respectively. The drink was comprised of various amounts of royal lotus petals at 1.25, 1.5, 2.0 and 2.5%. The results showed that 2.0% of royal lotus petals in the mixed herbal drink contained 10°Brix. Regarding the acceptance of the consumers, 2.0% of the lotus petals in the mixed herbal drink recipe was highly satisfied. The antioxidant activity of dried royal lotus petals in the bael-rosella mixed herbal drink showed the amounts of DPPH, metal chelation (MC50) and inhibition of lipid peroxidation (LC50) at 0.91±0.01 mg/mL, 10.79±1.76 mg/mL and 11.96±1.21 mg/mL, respectively. Hence, the bael-rosella mixed herbal drink added with royal lotus petals can be considered as a healthy herbal drink.
