Cochineal dye is a natural colorant derived from the crushed bodies of the female cochineal insect, primarily found on cacti in Central America and South America. This vibrant red dye has been used for centuries in textiles, cosmetics, and food products due to its bright hue and stability. The dye is often labeled as E120 in food products and is popular in items like yogurt, candies, and beverages. Cochineal dye is considered a more sustainable alternative to synthetic dyes, appealing to those seeking natural ingredients in their products.
