What is the waxy coating on a red bell pepper?

The waxy coating on a red bell pepper is a natural protective layer called cutin, which is part of the plant's cuticle. This coating helps to retain moisture, protect against pathogens, and reduce water loss. Additionally, some commercial bell peppers may have an added food-grade wax to enhance their appearance and shelf life. Overall, this waxy layer contributes to the bell pepper's freshness and durability.
