La oleorresina de pimentón (Capsicum annuum L.), la cual contiene fundamentalmente carotenoides, capsaicinoides y algunas vitaminas, tradicionalmente se usa en la industria alimentaria. Ésta se obtiene mediante un proceso con las siguientes etapas: a) escaldado, b) troceado, c) secado, d) molienda, y e) extracción con solventes volátiles (hexano, acetona, acetato de etilo). Los pigmentos que se extraen se analizan mediante HPLC en fase reversa y se comparan con la oleorresina de paprika comercial importada por la empresa TECNAS®. El rendimiento que se obtiene en el laboratorio está entre el 3 y 6%. Los resultados muestran la importancia del escaldado y del secado: el escaldado permite alcanzar una humedad del 13,56% en 320 min (sin escaldar en el mismo tiempo se llega al 21,01%) y el secado posibilita la extracción con solventes.Oleoresin from sweet pepper (Capsicum annuum L.), which contains mainly carotenoids, capsaicinoids and some vitamins, has been currently used in the food industry. and is obtained with the following procedure: a) scalding, b) chopping, c) drying, d) milling, and e) solvent extraction (hexane, acetone, ethyl acetate). Extracted pigments are analyzed using reverse phase HPLC and the results are compared with the oleoresin obtained from comercial paprika imported by TECNAS®. The yield achieved in the laboratory is 3-6%. The results show that scalding and drying are important: the scalding allows to reach an humidity of 13.56% in 320 min (without scalding the humidity reached is 21.01%) and the drying allows extraction with solvents.
