Definitions
- the invention relates to the field of natural odors and perfumes. More particularly, the invention relates to a process for extracting an odor from a plant material and its provision in solid form. This process combines steps of extraction, gas dissolution, cryogenics, or even lyophilization. The odor thus captured in the form of a frozen matrix or of a dehydrated powder can be used as a natural perfuming ingredient, in particular in cosmetics.
- the invention relates very particularly to the production of perfume extracts derived from mute flowers.
- Patent FR3011848A1 describes a process for obtaining an oily plant extract from plant material comprising the steps of: a) mixing said raw material with at least one fatty substance; b) heating said mixture by microwave at a power of 0.1 to 5 watts per gram of mixture to a temperature of 25 ° C to 60 ° C; and c) recovering the fatty substance which forms after mixing and heating the oily extract.
- Patent FR3081684A1 describes a process for obtaining a product in the form of frozen granules, particles or balls rich in dissolved gas and associated equipment from a liquid, semi-liquid or pasty matrix comprising the steps of gasifying the matrix by incorporation of a gas, in dispensing the matrix in the form of drops and cryogenizing the matrix drops by immersion in a cryogenic fluid, characterized in that the step of gasification of the matrix consists in dissolving a large quantity of the gas generated by evaporation of the cryogenic fluid in the matrix drops by increasing the number of gas molecules in a zone of high gas density, called a zone of high molecular density, located above the surface of the cryogenic fluid and on the trajectory of drops of matrix before their immersion in the fluid, said zone of high molecular density being created by carrying out the gasification and cryogenization of the gasified drops within a closed enclosure arranged to allow evacuation of the gas generated by the evaporation of the cryogenic fluid by natural convection.
- the inventors have developed a process making it possible to extract an odor from a plant material and to preserve it in solid form, either frozen or in the form of a dehydrated powder. Remarkably, it extracts the smells of mute flowers.
- This extraction process comprises the following steps: a) Disposing of a plant material b) Carrying out a treatment of said plant material, optionally under an inert atmosphere, in order to have a product in the form of a liquid matrix, semi- liquid or pasty c) dissolving a gas in said matrix by passing through a zone dense in gas molecules, such a density being obtained (i) either by a flow of gas generated by the evaporation of a cryogenic fluid, (ii ) or by an increase in pressure; d) Cryogenizing said gas-rich matrix obtained in step c) under pressure and temperature conditions making it possible to maintain said gas in said matrix to obtain frozen granules, particles or beads.
- the frozen granules, particles or beads can be lyophilized so as to obtain an odorous extract in the form of a dehydrated powder.
- the present invention has many advantages with regard to the state of the art.
- the proposed extraction process is simple, fast and inexpensive. It uses two technologies known to those skilled in the art, namely cryogenics and lyophilization.
- the first step is a step of freezing or deep freezing by cryogenics.
- the method involves first of all the dissolution of a gas in the matrix before cryogenics, then carrying out the cryogenics step under pressure so as to maintain throughout the process the gas trapped in the matrix and in particular in the frozen granules, particles or beads.
- the presence of the gas in particular when it is an inert gas, protects the odorous matrix during freezing and allows substantial improvements both in the properties of the products obtained and in the drying by freeze-drying.
- the second step is a freeze-drying step.
- Lyophilization is a process of dehydration by sublimation of water under conditions of temperature and pressure allowing the water contained in solid form in the products to be transformed directly into water vapor for elimination. It makes it possible to obtain dehydrated products in powder form, the odorous properties of which are maintained.
- the extraction process according to the invention has the advantage of being rapid. Cryogenics is an almost instantaneous process, making it possible to continuously produce and at high rates (several hundred kg per hour on standard equipment) balls of initially fluid product. The time saving is considerable compared to freezing in a cold room, even if they operate at very low temperatures (-40 ° C to -80 ° C in general).
- the cryogenized beads are extracted from the materials producing them at temperatures generally between -80 ° C and -120 ° C, which makes it possible to start freeze-drying directly, with products whose temperature is around - 60 ° C, without a prior step of cooling. More surprisingly, the lyophilization time itself is very greatly reduced (down to a factor of at least 2).
- the combination of gas dissolution with cryogenics makes it possible to obtain frozen products containing a large amount of gas.
- this gas is not oxygen, oxidation reactions are avoided.
- the lyophilization of such products makes it possible to eliminate the major part of the water contained in the product.
- the quality of the dehydrated products is higher than that of the lyophilized products obtained by a conventional process because the conditions set implemented in this process are on the whole softer, less aggressive and less destructuring for the matrix. These properties, odorous in particular, are therefore better preserved.
- the frozen granules, particles or beads as well as the lyophilized powder obtained at the end of the process contain the odorous molecules extracted from the biological material and the odorous ingredient is of high quality.
- the inventors have in fact observed that the odor contained in these solid ingredients faithfully reproduces the odor of fresh plant material and that this odor lasts for a very long time without deteriorating.
- these fragrant ingredients do not contain alcohol and therefore make it possible to formulate perfumes without alcohol. The fragrant ingredients therefore have significantly improved properties compared to the extracts available hitherto.
- the method of the invention makes it possible to extract the odors from mute flowers. This result is extremely interesting and opens new horizons in the world of perfumery which can now access the complex scents of mute flowers thanks to natural ingredients of high olfactory quality at acceptable costs.
- the formulation of perfuming compositions from odorous ingredients offered in the form of dehydrated powder is also advantageous. It provides ease of use, dosage and storage and the shelf life is long due to the stability of the product.
- the use can in particular be facilitated by a formulation of the powder in a compressed form (compact powder), offered for example in a format of small pebbles of a determined weight, or of granules.
- Another advantage of the dehydrated powders according to the invention is that they dissolve quickly and leave no deposit, which allows them to be easily introduced into liquid perfume compositions.
- a first object of the invention relates to a process for preparing an odorous ingredient in solid form from a plant material comprising the steps of: a) disposing of a plant material b) carrying out a mechanical treatment of the raw material , optionally under an inert atmosphere, in order to have a product in the form of a liquid, semi-liquid or pasty matrix c) Dissolving a gas in said matrix by passing through a zone dense in gas molecules, such a density being obtained (i) either by a flow of gas generated by the evaporation of a cryogenic fluid, (ii) or by an increase in pressure; d) Cryogenizing said gas-rich matrix obtained in step c) under pressure and temperature conditions making it possible to maintain said trapped gas in order to obtain frozen granules, particles or beads.
- the method further comprising the steps of: a) Lyophilization of said granules, particles or beads; b) Obtaining said odorous ingredient in the form of a dehydrated powder.
- the dissolved gas can be an inert gas such as nitrogen, argon ... or a non-inert gas such as CO 2 or nitrous oxide, or a mixture of gases.
- a particularly preferred cryogenic fluid is liquid nitrogen.
- under pressure within the meaning of the invention, is meant conditions which allow the dissolution and / or trapping of a gas in a matrix and / or its maintenance in said matrix during deep freezing. Pressurization can be obtained either by increasing the pressure or by bringing the matrix into contact with a cryogenic fluid, the evaporation of this gas creating a gas molecule density equivalent to pressurization so that the gas molecules dissolve in the matrix.
- this pressure is greater than atmospheric pressure, and may in particular be greater than 0.5 bar, 1 bar, 2 bars, 5 bars, 10 bars, 50 bars, 100 bars, 200 bars, or even 250 bars or more. In a particular embodiment, it is between 2 and 100 bars.
- the pressures expressed in this document correspond to relative pressures, that is to say that atmospheric pressure is considered as a pressure of 0 bar.
- the zone dense in gas molecules is obtained at least in part by virtue of a flow of gas generated by the evaporation of a cryogenic fluid. It can be obtained by combining the evaporation of a cryogenic fluid with an increase in pressure.
- a gas flow generated by the evaporation of a cryogenic fluid cover the flow resulting directly from the evaporation of a cryogenic fluid as well as any controlled flow (direction, flow rate, etc.), by injection gas or by suction for example, which allows the creation of one or more exchange zones between the matrix and a large number of gas molecules.
- step d) The pressure and temperature conditions applied in step d) must make it possible to maintain the gas trapped in the matrix in step c).
- Those skilled in the art will know how to adjust the pressure and temperature conditions during step d), so that the solubility of the gas in the matrix is greater than or equal to that used during step c). Said solubility is in particular influenced by the temperature (for gases it increases when the temperature decreases) and by the pressure (balance of the partial pressures between the matrix and the gas).
- steps c) and d) take place under correlated conditions (between these two steps) in order to allow the gas to dissolve in the matrix and its conservation inside the matrix during cryonics.
- the process As regards the implementation of the process as a whole, it is possible to chain the stages of the process one after the other and in particular to carry out the lyophilization stage immediately after the cryogenics stage. In addition, the process can be carried out continuously. It is also possible to keep the product in frozen form at the end of the cryogenics step and to carry out the lyophilization subsequently, after a negative cold storage time to keep the products in the solid state (for example at - 20 ° C). In both cases, the advantage of the process is retained.
- the lyophilization step can be carried out either immediately following the cryogenics step, or subsequently after storage of said frozen granules, particles or beads.
- the conditions of the process can be adapted according to the shape of the matrix to be dehydrated, in particular the pressure during the cryogenic step, and the lyophilization parameters. Those skilled in the art will know how to make such adaptations.
- the matrix obtained by treating the plant material is transferred rapidly to the gas dissolution and cryogenics apparatus in order to limit the degradation or denaturation of the compounds.
- plant material within the meaning of the invention is understood to mean plants in the general sense, considering that all plant material is odorous, the intensity of this odor being able to vary. It may be in particular flowers or parts of flowers such as the petals, pistils, leaves, stems, but also herbaceous plants such as aromatic herbs, fruits of any type such as raspberries, lychees, apples, vanilla pods or roots such as ginger, or spices.
- the plant material is preferably fresh, or freshly cut, so that the odorous molecules are not altered, and that the odor emanating from the plant material is as close as possible to the natural state.
- the plant material consists of flowers and its different parts, in particular the petals.
- treatment of the plant material is meant any transformation of the plant material into a liquid, semi-liquid or pasty matrix such as mechanical extraction (using a juice extractor), pressing, mixing. .
- flower within the meaning of the invention, is meant a flower from which neither essence nor absolute can be extracted.
- mute flowers are, for example, lily, violet, hyacinth, duddleia, peony, freesia, lily of the valley, honeysuckle, gardenia, carnation, pittosporum, syringa, sweet pea , glycine and heliotrope.
- the plant material originates from a mute flower.
- the plant material consists exclusively of petals or exclusively of petals and pistils of flowers.
- a second subject of the invention relates to a natural odorous ingredient obtained according to the process described above, in the form of frozen granules, particles or balls.
- a third subject of the invention relates to a natural odorous ingredient obtained according to the process described above, which is in the form of a dehydrated powder.
- This powder can be 100% derived from the fragrant plant material.
- Such a product if it is technically feasible (sufficient yield, non-oily extracted product, etc.) will be very concentrated, which can be a high quality index.
- the powder may also contain, in addition to the plant material, a support which makes it possible to fix the odorous molecules.
- a support can consist of maltodextrins or of a natural vegetable support for a 100% vegetable ingredient.
- the fragrant ingredient which is provided in frozen form or as a dehydrated powder is obtained from a mute flower.
- a fourth subject of the invention relates to an odorous composition comprising at least one odorous ingredient as defined above.
- such a composition comprises at least one fragrant ingredient obtained from a mute flower.
- a fifth subject of the invention relates to a process for preparing a liquid odorous composition comprising a step of dissolving at least one odorous ingredient in the form of a dehydrated powder as defined above.
- the fragrant ingredients and the compositions containing them can be used in perfumery, namely in body perfumes and room fragrances, but also in cosmetics.
- Figure 1 Chromatograms obtained following analysis by a Héraclès II electronic nose of AlphaMos (double ultra-rapid gas phase chromatography) of the lilac powders prepared by applying the extraction process according to the invention (A: column 1; B: column 2) .
- the petals were separated from the flowers manually before being passed through an ANGEL 7500 horizontal juice extractor.
- the juice thus collected was immediately treated in equipment allowing it to be cryogenized while trapping dissolved gas therein, according to the process described in patent WO2019 / 234341 for example.
- the frozen beads thus obtained were then lyophilized according to standard conditions in a CHRIST alpha 1-8 freeze-dryer, until “dry” powders were obtained (more weight loss measured).
- the first remarkable element comes from the quantity of powder thus obtained.
- the powder yields were around 5%, which is very high since no support was added and it is therefore only material initially present in the flowers. petals.
- Lyophilization supports are generally added to the preparations to be lyophilized, in order to guarantee the presence of a sufficient dry extract for the binding of molecules of interest during the treatment and also to reduce production costs.
- the yield obtained during this preparation is already very convincing on these two points without having to add anything.
- the second very remarkable element is the smell of the products thus obtained, which were very clearly identified as being those of the two respective flowers by the various panels consulted.
- Electronic nose analyzes ( Figures IA and IB) have also made it possible to confirm the presence in the product of characteristic peaks associated with chemical compounds known to be significant contributors to the scents of lilac flowers:
- (E) -ocimere which is the major component; lilac aldehydes and lilac alcohols, which each have several dimers and are among the most characteristic compounds; benzyl methyl ether, 1,4-dimethoxybenzene and indole, which are the other characteristic compounds of the scent of lilac.
- the reference data used are those of the software coupled to the Héraclès II measuring device and of the NIST WebBook available in particular from the address: https://webbook.nist.gOv/chemistry/#Search.
- Jasmine flowers were collected.
- the petals and pistils were separated manually before being passed through an ANGEL 7500 horizontal juice extractor.
- a portion of the juices thus collected were immediately treated in equipment allowing them to be cryogenized while trapping dissolved gas therein, according to the report. process described in patent WO2019 / 234341 for example.
- the frozen beads thus obtained were then lyophilized according to standard conditions in a CHRIST alpha 1-8 freeze-dryer, until “dry” powders were obtained (no more weight loss measured).
- 50 g of maltodextrins were added each time, then the mixtures thus obtained underwent the same process as described above, until powders were obtained.
- a support such as maltodextrins
- the dry powder alone can become liquid again, this is the case in particular when the oily fraction is too large; it is then necessary to add a support at the time of lyophilization.
- by adding a support we increase the yield as illustrated above, which is economically advantageous, and allows the standardization of products.
