A method of providing an essential oil extract of capsicum, and the extract itself, are provided. The extract contains capsaicinoid and terpene. Capsicum from which seeds and stems have preferably been removed is mixed, in powder form, with a solvent, especially pentane, to dissolve at least some of the capsicum. During or after the mixing step, the liquid solution of capsicum in the solvent is brought to a temperature of less than or equal to 64~C to significantly reduce the solvent content thereof and produce an essential oil extract that contains capsaicinoid and terpene, especially in the naturally occurring ratio thereof.
L'invention concerne un procédé permettant de fournir un extrait d'huile essentielle de capsicum, et l'extrait lui-même. Cet extrait contient un capsaicinoïde et un terpène. Le capsicum, duquel les graines et les tiges ont été de préférence enlevées, est mélangé, sous forme de poudre, à un solvant, notamment du pentane, afin de dissoudre au moins une partie du capsicum. Pendant ou après l'étape de mélange, la solution liquide de capsicum dans le solvant est portée à une température inférieure ou égale à 64 ·C afin de réduire de manière significative la teneur en solvant et de produire un extrait d'huile essentielle qui contient un capsaicinoïde et un terpène, notamment selon un ratio qui s'établit naturellement.
