Abstract
This article reports the extraction processing and stability of the natural purple pigment from eggplant.Eggplant purple pigment can be extracted by absolute ethyl alcohol. The eggplant purple pigment darkens as the temperature rises. The alkalescence and ammonium oxalate can delay its degeneration and enhance the stability.
