Paprika oleoresin (also known as paprika extract and oleoresin paprika) is an oil-soluble extract from the fruits of Capsicum annuum or Capsicum 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]
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.
