Reactive red 195 azo dye, used in the textile industry, is sometimes fraudulently added to certain foods, such as fruit or spice concentrates.
The most frequently adulterated food colors are red beet (Beta vulgaris) and Hibiscus sabdariffa, a plant from which carcadè is obtained, the well-known thirst-quenching drink.
The addition of synthetic dyes, not allowed by law, is a practice used by unscrupulous dealers, who prefer it to natural pigments as these are more sensitive to changes in light, heat and pH than their synthetic counterparts and high doses are required to obtain the desired shades and color intensities.
