Formulation and Evaluation of Antioxidant Activity of Health Drink

Abstract

An antioxidant health drink was prepared by using various extracts of the fruits. It was further evaluated on the basis of stability studies. Other parameters like pH, viscosity, density, colour, odour and taste were also taken into consideration. In vitro free radical scavenging activity by using beta-carotenes bleaching & lipid per oxidation method for the formulation was performed. The inhibition activity of the health drink on the peroxide ion of linoleic acid was measured by folic thiocyanate method in comparison to methanolic extract of green tea, ginkobiloba, vit.E, and BHA as positive controls. The health drink formulation of various fruits exhibited strong antioxidant activity. The health drink also showed promising stability studies.
