First isolated in 1876, capsaicin stimulates gastric secretions and, if used in excess, causes inflammation. It is a tasteless, odorless white crystalline substance. Its level varies widely in capsicum peppers, from less than 0.05% in the mildly pungent types to as high as 1.3% in the hottest chilies. The pungency level is usually represented in Scoville heat values. Pungency levels vary in the same variety, by geographical region, and in maturity levels. Volatile oil content is low in all capscicums. The pigment responsible for the color in paprikas is capxanthin, a carotenoid. Other carotenoids present are capsorubin, zeaxanthin, lutein, kryptoxanthin and alpha and beta-carotene. Continue reading
