The dried red peppers (DRPs) were obtained by desiccating FRPs
(whole pods) under solar light (the temperature about 20e28C,
8h10 days) or under 50C (for 8 h3 days) in an electrothermal
drying oven to constant weight. Then the pericarp were collected
and crushed to a homogeneous size in a mill, sieved through a
No.40 mesh
