Abstract
The effect of light on the stability and stabilization of the anthocyanins isolated from freeze-dried aqueous extracts of fruits of Euterpe oleracea were studied, using crude and purified extracts at pH 2.2 and 3.0. Crude extract was 80.0 times more stable than the purified one at pH 2.2 and 24.3 at pH 3.0. Stabilization with tannic acid was attempted and resulted in 65% half-life increase of the anthocyanins of the crude and a considerable half-life increase (610%) of the purified one.
