Grape Skin Extract is a natural red colorant with a high concentra- tion of red anthocyanic pigments which provide its physicochemi- cal properties. these pigments are responsible for the red, purple, violet, and blue hues of flowers and fruits. it is prepared by aqueous extraction of the fresh seedless marc remaining after the grapes have been pressed in the production of grape juice and wine. it contains the common components of grape juice, but in different propor- tions. the color depends upon the medium and the ph. in an acid medium and up to ph 4.5–5.5, the color is violet and becomes blue at ph 6.5. it has excellent water solubility and fair heat, light, and chemical stability. it can be used in soft drinks at 0.2–0.4%, and in candies at 0.5–1.5%.
