Definitions
- the present invention relates to a process for obtaining an avocado unsaponifiable agent rich in furan lipids.
- the avocado comprises, in a known manner, specific lipids of the furan type, the main component of which is a linoleic furan:
- R is a straight C 11 -C 19 hydrocarbon chain, preferably C 13 -C ⁇ saturated or comprising one or more ethylenic or acetylenic unsaturations.
- L 1 unsaponifiable is the fraction of a fatty substance which, after prolonged action of an alkaline base, remains insoluble in water and can be extracted with an organic solvent.
- Five main groups of substances are present in most unsaponifiables of vegetable oils: saturated or unsaturated hydrocarbons, aliphatic or terpene alcohols, sterols, tocopherols, carotenoid and xanthophilic pigments.
- Patent FR 91 08301 describes a process for obtaining an avocado unsaponifiable material from an avocado oil enriched in one of its fractions, called H, corresponding in fact to these same furan lipids.
- the preparation of such an unsaponifiable matter rich in furan lipids, the content of which can vary from 30 to 60%, is essentially conditioned by controlled heating of the fresh fruit, previously sliced into thin strips, at a temperature between 80 and 120 ° C. , and for a period preferably chosen between 24 to 48 hours.
- the heat treatment can be preceded by dehydration of the fruit, but preferably it is carried out concomitantly with the drying of the fruit. This heat treatment allows, after extraction, to obtain an avocado oil rich in furan lipids.
- the unsaponifiable fraction is obtained according to a conventional saponification process, supplemented by a liquid-liquid extraction step.
- This method has the first drawback of having to heat to a relatively high temperature, at least equal to 80 ° C., for fairly long times, 1 to 2 days, fruit strips rich in lipids which are easily oxidizable under these conditions.
- this type of heat treatment causes in plant food materials, secondary reactions of degradation well known to those skilled in the art, such as the Maillard reactions, which cause unwanted browning of the products, and the appearance of often unpleasant flavors and aromas.
- this type of heat treatment carried out in air, without prior inerting, can be accompanied by significant chemical modifications, in particular in the presence of heat-sensitive substrates such as lipids (e.g. unsaturated fatty acids) and their unsaponifiable fraction (e.g. Vitamin E) .
- heat-sensitive substrates such as lipids (e.g. unsaturated fatty acids) and their unsaponifiable fraction (e.g. Vitamin E) .
- the thermal processes will favor the thermo-oxidation of the substrates, the radical reactions responsible for the appearance of peroxides, but also of intra or intermolecular condensation reactions at the origin of the formation of heavy products.
- the Applicant has thus developed a process, making it possible to obtain, with a high yield, an unsaponifiable material of avocado rich in furan lipids, that is to say a content varying from 50 to 80%, having low contents of heavy products and in peroxides.
- This process includes the following successive steps:
- a step of concentrating the oil in its unsaponifiable fraction then a heat treatment at a temperature which can vary from 80 to 150 ° C., optionally under an inert atmosphere, followed
- avocado having undergone prior processing is meant the co-products resulting from the extraction processes of fresh avocado oils, in particular those resulting from the so-called centrifugation processes. Mention may in particular be made, as “avocado having undergone prior processing”, of i) the avocado milks obtained by pressing the pulps, or ii) the products for settling the pulps partially de-oiled by centrifugation, products generally present at the outlet of centrifugal colanders, or else the centrifuge bases produced during separation.
- avocado cake co-produced during the cold pressing of the fruits ( fresh or dried) or liquid-solid extraction of avocado oil from fresh or dried fruit, using an organic solvent, can also constitute as it is, an alternative raw material usable in the part of the present invention.
- avocado pits can potentially constitute a source of lipids and be used in the context of the present invention.
- step (1) of the process all of the techniques known to those skilled in the art and which make it possible to extract water from a compound.
- these techniques mention may be made of drying under a stream of hot air or under a controlled atmosphere (eg nitrogen), at atmospheric pressure or under vacuum, in a thick layer or a thin layer, but also the microwave drying, spray drying, freeze drying and osmotic dehydration in solution (direct osmosis) or in solid phase (eg drying in osmotic bags).
- a controlled atmosphere eg nitrogen
- microwave drying spray drying, freeze drying and osmotic dehydration in solution (direct osmosis) or in solid phase (eg drying in osmotic bags).
- drying in ventilated dryers in a thin layer and under a stream of hot air, at a temperature of between 70 and 75 °. C, for 8 to 36 hours is preferred.
- the extraction step (2) can be carried out by any means known to those skilled in the art, preferably by simple cold pressing or with a solvent at low temperature.
- the heat treatment step implemented in step (3) a. or b. can be done in the presence or not of an acid catalyst.
- Acid catalysts in the broad sense are understood to be so-called homogeneous inorganic and organic catalysts such as hydrochloric, sulfuric, acetic or paratoluenesulfonic acids but also, and preferably, heterogeneous solid catalysts such as silica, alumina, silica-aluminas , zirconia, zeolites, acid resins.
- acid aluminas with large specific surfaces will be chosen, that is to say at least equal to 200 m 2 / g.
- Preferred for the implementation of the process of the invention are catalysts of the acid aluminas type.
- this heat treatment is carried out under a continuous stream of nitrogen.
- the heat treatment temperature is between 80 and 130 ° C.

- application EP 493 144 describes a molecular still of this type.
- the product to be distilled is spread in a thin layer on the heated surface (hot surface) of a conical rotor rotating at high speed.
- the distillation chamber is placed under vacuum. Under these conditions, there is evaporation and not boiling, from the hot surface, of the constituents of the unsaponifiable, the advantage being that the oil and the unsaponifiable (these products being reputed to be fragile) are not degraded during evaporation.
- Scraped film type molecular stills also known to those skilled in the art, include a distillation chamber with a rotating scraper, allowing continuous spreading over the surface evaporation (hot surface) of the product to be distilled.

- Step (4) of saponification of the oil or oily extract can be carried out in the presence of potassium hydroxide or sodium hydroxide in an alcoholic, preferably ethanolic, medium, followed by one or more extraction (s).
- Extraction with an appropriate organic solvent (liquid-liquid extraction) in order to separate the soaps from fatty acids and the unsaponifiable compounds is particularly suitable.
- the suitable organic solvent can be, for example chosen from the group of alkanes, halogenated alkanes, aromatic solvents, ethers such as methyltertiobutyl ether (MTBE) and ethyl ether, or any other suitable solvent immiscible with the hydro-alcoholic solution.
- a halogenated alkane will be chosen, in particular 1, 2-dichloroethane.
- the extraction solution obtained is preferably then centrifuged, filtered and then washed with water to remove the residual traces of alkalinity. Finally, the extraction solvent is evaporated carefully to recover the unsaponifiable matter.
