Fuente: WIPO "essential oil or extracts" Patent 529902

Methods 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, particularly 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 DEG 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.
