Paprika Capsicum annuum L. contains useful molecules such as carotenoids and polyunsaturated fatty acids, which are considered high-value functional and health ingredients. To obtain these compounds, paprika was extracted using different methods (Soxhlet, SC-CO2, and SC-CO2 with co-extractant) and at different parameters. The results showed that the carotenoid content decreased with the addition of the co-extractant while the fatty acid content and yield increased. It was found that the highest carotenoid content (capsanthin > β-carotene > capsorubin > zeaxanthin > β-cryptoxanthin > violaxanthin) was obtained at 50 °C/45 MPa for SC-CO2 extraction. Paprika extract rich in polyunsaturated fatty acids (linoleic, oleic, and α-linolenic acid) was obtained at 40 °C/25 MPa for SC-CO2 with co-extractant. The PUFA/SFA ratios for paprika extract were in agreement with the recommendations of nutritional guidelines. The use of SC-CO2 for the extraction of Capsicum annuum allowed us to obtain a high-quality, rich in carotenoids and polyunsaturated fatty acids, extract that can be used as ...
