Red Cabbage Juice

Red cabbage juice is a natural coloring agent derived from the leaves of the red cabbage plant. The vibrant color comes from pigments called anthocyanins, which change hue depending on the pH level of the food. It is typically extracted by pressing the cabbage leaves and filtering the juice.

Manufacturers use red cabbage juice as a natural food colorant to provide red, purple, or blue shades, depending on the acidity of the product. It is often found in baked goods, beverages, and confectionery where a natural alternative to synthetic dyes is desired.

Red cabbage juice is generally recognized as safe (GRAS) by the FDA for use as a food ingredient. Anthocyanins, the compounds responsible for its color, are antioxidants found in many fruits and vegetables. JECFA has evaluated anthocyanins and did not set a numeric limit (ADI not specified). Research into the health benefits of anthocyanins is ongoing, but they are not typically associated with adverse effects at levels found in food.
