Natural plant colorants widely used in Vietnam traditional food culture

Abstract

The artificial colorants have gradually been being replaced by natural pigments which are becoming increasingly important in Vietnam and other parts of the world due to the potential noxiousness of man-made food dyes to human health. This research covers colorant plants and sources used commonly in the food culture of ethnic communities in Vietnam with the current trend toward natural pigments and coloring foods. As a result, we reported 49 species which can be used as natural food pigments and of these, 7 colorant plants used mostly in Vietnam traditional food culture were detailed.
