Chemical evaluation of some paprika (Capsicum annuum L.) seed oils

Abstract

AbstractThe oil contents of seeds from paprika (Capsicum annuum L.) collected from different locations in Turkey and Italy varied in a relatively wide range from 8.5 g/100 g to 32.6 g/100 g. The fatty acid, tocopherol and sterol contents of the oils from different paprika seeds were investigated. The main fatty acids in paprika seed oils were linoleic acid (69.5–74.7 g/100 g), oleic acid (8.9–12.5 g/100 g) and palmitic acid (10.7–14.2 g/100 g). The oils contained an appreciable amount of γ‐tocopherol (306.6–602.6 mg/kg), followed by α‐tocopherol (7.3–148.7 mg/kg). The major sterols were β‐sitosterol (1571.4–4061.7 mg/kg), campesterol (490.8–1182.7 mg/kg), and Δ5‐avenasterol (374.5–899.6 mg/kg). The total concentration of sterols ranged from 3134.0 mg/kg to 7233.7 mg/kg. Remarkable amounts of cholesterol were found in the different samples (164.6–491.0 mg/kg). The present study showed that paprika seeds are a potential source of valuable oil that could be used for edible and industrial applications.
