- ... Purple sweet potato anthocyanins are common natural pigments widely used in food industry, while they are often thermally processed in application. Degradation of anthocyanins, formation of polymers and color changes of purple sweet potato extract (PSPE) were investigated at 90 °C in the range of pH 3.0–pH 7.0. Data analysis indicated a first-order reaction for anthocyanins degradation in solution ...
