Paprika oleoresin (also known as paprika extract and oleoresin paprika) is an oil-soluble extract from the fruits of Capsicum annuumorCapsicum frutescens, and is primarily used as a colouring and/or flavouring in food products. It is composed of vegetable oil and capsanthin and capsorubin, the main colouring compounds (among other carotenoids).[1] Commercial products are generally standardized to contain 7% total caretinoids. It is much milder than capsicum oleoresin, often containing relatively little capsaicin.[2]

Extraction is performed by percolation with a variety of solvents, primarily hexane, which are removed prior to use. Vegetable oil is then added to ensure a uniform color saturation.[3]
Foods colored with paprika oleoresin include cheese, orange juice, spice mixtures, sauces, sweets, ketchup, soups, fish fingers, chips, pastries, fries, dressings, seasonings, jellies, bacon, ham, ribs, and among other foods even cod fillets.[4] In poultry feed, it is used to deepen the colour of egg yolks.
In the United States, paprika oleoresin is listed as a color additive “exempt from certification”.[5] In Europe, paprika oleoresin (extract), and the compounds capsanthin and capsorubin are designated by E160c.

Paprika extract used to colour foods has, in contrast to the oleoresin used as a flavouring agent [Capsicum Oleoresin], a very low content of capsaicin and hence little or no pungency.
