STABILISED COLORANT COMPOSITION

摘要

The present invention discloses a stable colorant composition of a plant extract, which has a high staining power in the purple-red range. Accordingly, the present invention provides a stable colorant composition of a plant extract that has a pigment concentration of more than 811 mg per 1000 g of fresh weight of pitaya fruit which makes the preparation of food colorant from the fruit easier and less costly. The stable betacyanin concentrate can be suspended in a food-compatible liquid, as a food colorant or food additive.
