Are chili pepper acidic or basic?

Chili peppers are generally considered to be acidic due to their natural pH level, which typically ranges from 4.5 to 6.0. This acidity comes from the presence of organic acids, such as citric and ascorbic acid. However, they are not highly acidic compared to other foods like citrus fruits. The perceived spiciness of chili peppers is primarily due to the compound capsaicin, rather than their acidity.
