The main components of Gardenia Yellow pigment are carotenoid Croc in and crocetin, and it also contains iridoid glycoside gardenoside, flavone and chlorogenic acid. Mixed Tocopherols Oil and safranic acid are rare water-soluble carotenoids. There are many conjugated double bonds in the molecule. On the one hand, Beet Root Powder give gardenia pigment yellow, on the other hand, they are one of the reasons for the instability of gardenia pigment. There are seven kinds of safranic acid derivatives in gardenia yellow pigment. There is little difference in chroma and brightness between the seven derivatives. However, with the increase of the number of Sweet Potato Powder linked to safranic acid, the hue of the derivatives decreases and the color changes from red to yellow.
