What does pungency measure?

Pungency specifically refers to the intensity of heat or spiciness in peppers, primarily associated with the presence of capsaicin. This compound is responsible for the hot sensation that one experiences when consuming spicy foods. The higher the concentration of capsaicin, the greater the pungency, resulting in a higher heat level. Regarding the other aspects listed, sweetness relates to the flavor profile, color is a physical characteristic, and size refers to the dimensions of the pepper. None of these factors measure the heat or spiciness attributed to pungency. Therefore, option B is the most accurate representation of what pungency measures.
