What is oleo-resin capsicum derived from?

Oleo-resin capsicum is derived from cayenne pepper, which is a specific type of chili pepper known for its heat and pungency. The extraction process involves collecting the oleoresin, which is a concentrated substance containing both the oil and resin from the capsicum plant. This oleoresin is rich in capsaicin, the compound responsible for the spiciness of cayenne peppers.

Cayenne pepper is utilized in various applications, including culinary uses, medicinal purposes, and even as an ingredient in products that deter pests due to its heat. The other options, while related to the capsicum family, do not specifically produce oleo-resin capsicum in the same concentrated form as cayenne. For instance, paprika is a milder variety typically made from sweeter peppers, bell peppers do not contain capsaicin at significant levels and have no heat, and chili powder is often a blend that may contain cayenne but is not solely derived from it. This makes cayenne the correct answer in the context of oleo-resin capsicum.
