The golden yellow color of turmeric is due to curcumin. It also contains an orange-colored volatile oil. Turmeric makes a poor fabric dye, as it is not very lightfast, but is commonly used in Indian clothing, such as saris and Buddhist monks’ robes.[6] It is used to protect food products from sunlight, coded as E100 when used as a food additive. The oleoresin is used for oil-containing products. A curcumin and polysorbate solution or curcumin powder dissolved in alcohol is used for water-containing products.
