Abstract

Clitoria ternatea, Hibiscus sabdariffa and Ipomoea tricolor are known for their functional properties as antioxidant activity due to their anthocyanins content which is responsible for the color intensity. The objective of this study was to develop mixed antioxidant drink in the form of Ready-To-Drink beverage from C. ternatea, H. sabdariffa and I. tricolor flower extracts that resulted in good sensory acceptance. The development of mixed antioxidant drink resulted in an optimum formula of 46.67 ml H. sabdariffa, 37.50 ml I. tricolor and 15.82 ml C.ternatea flower extracts with 10% sugar (w/v) and pH 3.0 conditions. This formula scored 7 in hedonic test which means “liked” by the panelists. The combination of flower extracts also proven to give more stable color compared to single flower extract by having lower k-value when it was stored at accelerated condition (45° C). The mixed antioxidant drink product has a good stability in regard to antioxidant activity, total phenolic content, total anthocyanins content and color intensity on both refrigerator and room temperatures. However it is highly recommended to store the drink in low temperature to maintain the functional properties.
