Abstract
The invention relates to the field of natural scents and fragrances. More particularly, the invention relates to a process for extracting scents from a plant material and to the provision thereof in solid form. This process combines steps of extraction, gas dissolution, cryogenicization, or even freeze-drying. The scent thus captured in the form of a deep-frozen matrix or of dehydrated powder can be used as a natural perfuming ingredient, in particular in cosmetics. The invention relates very particularly to the obtaining of perfuming extracts derived from mute flowers.
Claims8
A process for preparing a fragrant ingredient in solid form from a plant material wherein the process comprises:
- a) providing a plant material obtained from a mute flower;
- b) transforming said plant material into a liquid, a semi-liquid or a pasty matrix;
- c) dissolving a gas in said matrix by passage through a dense zone of gas molecules, such a density being obtained (i) either owing to a flow of the gas generated by the evaporation of a cryogenic fluid, (ii) or by an increase in pressure;
- and
- d) Cryogenicizing said gas-rich matrix obtained in c) under pressure and temperature conditions allowing to keep said gas trapped in order to obtain frozen granules, particles or beads.
