Common NameCapsorubin
DescriptionCapsorubin, also known as E160 (capsorubin), belongs to the class of organic compounds known as triterpenoids. These are terpene molecules containing six isoprene units. Thus, capsorubin is considered to be an isoprenoid lipid molecule. As a food coloring, it has the E number E160c(ii). Capsorubin is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Outside of the human body, Capsorubin has been detected, but not quantified in, several different foods, such as red bell peppers, italian sweet red peppers, herbs and spices, orange bell peppers, and green bell peppers. This could make capsorubin a potential biomarker for the consumption of these foods. Capsorubin is a carotenoid found in red bell pepper (Capsicum annuum) and a component of paprika oleoresin. Capsorubin is found in Lilium pumilum and Nephroma arcticum. Capsorubin is a natural red dye of the xanthophyll class.
