Title: Studies on physicochemical characteristics of purple pigment
Abstract: In this experiments,purple pigment distilled from corn cob was used as material and studyed the physicochemical characteristics and stability.Result showed that the pigment was water-soluble.It was sensitive to light and heat.Fe~(3+) could decreased the absorbency.The reducer sodium sulfate and vitamin C had big influence on the pigment.Purple pigment was stable in acid conditionand unstable in alkaline environment.Sodium benzoic,glucose,sucrose and corn syrup had indistinctive effect on the pigment. It can change the physicochemical characteristics and sense properties notable when added to the food.
