Description
~23~33~
The present invention relates to crystallization nests lent aqueous emulsions ox anthill suitably an essential oil con-twining anthill and to a process for preparation thereof.
In a certain number of uses, more particularly pertain-in to food, it is necessary to be able to have stable aqueous emulsions of essential oils or of fat-soluble substances avail-able. This is more particularly the case for beverages which contain anthill (or essential oils containing anthill), in such a quantity that this anthill is not soluble in the medium in which it is included.
An emulsifying agent is then required, which possesses a set of properties such that it produces a stable emulsion for several weeks and even several months, is acceptable in food-stuffs, is compatible with the product to be emulsified and does not change the taste of the emulsified product. Numerous emulsi-liens can claim -to combine these various properties, but recent research has demonstrated that supineness and bile salts keenest-tuned two classes of products capable of being used as emulsi-liens.
The invention therefore provides crystallization-resis-lent emulsions of anthill comprising anthill, a continuous phase selected from the group consisting of water and water con-twining alcohol, an emulsifying agent selected from the group consisting of supineness and bile salts, and at least one triglyc-erode to retard the crystallization of anthill.
The present invention also provides a process for preparing the crystallization resistant emulsion which comprises the steps of: pa) mixing said anthill ingredient with said emulsifying agent and said triglyceride; (b) thereafter adding said continuous phase to the mixture obtained in step (a); and (c) stirring the mixture to form the desired emulsion.

The expression "aqueous emulsion" means an emulsion of which -the continuous phase is water and the discontinuous phase is the anthill or anthill containing essential oil (or Essex-tidally contains this essential oil). However, -the continuous phase of the emulsion may advantageously be constituted by water containing a certain proportion of alcohol (more particularly from 5 to 25% of alcohol), in particular when it is desired to prepare beverages containing anthill.
"Essential oil" is understood in particular to mean all oils extracted from plants and used in foodstuffs or perfumery.
The essential oils for use in the invention are essential oils containing anthill such as concentrated vegetable extract or anthill itself. Of course, as the present invention envisages emulsions, the quantity of anthill (or of essential oil contain-in anthill) used will be greater than the quantity of anthill soluble in the aqueous phase (pure water or alcoholized water) in which this anthill is emulsified.
Supineness, which form emulsifiers usable in the invent lion, are glucosidic substances of vegetable origin. Their privy ileged form of use in the present invention is a plant extract, it being understood that any plant containing supineness may be used.
By way of example, plants referenced in the Council of Europe's work "Aromatizing substances and natural sources of art-matizing substances" 1981 (Maisonneuve) will be cited, without this list being exhaustive.

It has generally been established that at least 2% by weight of saponin with respect to the anthill prod-vat to be emulsified should be used.
The analysis of saponin contained in an emulsion according to the invention is made in accordance with the method described in: "Chemischer Aufbau, physikalische ~igenshaften undo Unterscheidungsmerkmale einiger Polygala-Saponi.ne" published in : Douche Apothecary Zeitung, 108 Jahrgang No. 42 17.10.1968.
The bile salts usable according to the invention are essentially salts of colic, glycoholic, taurocholic or Dixie-colic acid. These salts are usable in the state of individual-iced products or preferably in the state owe mixtures of several salts.
At least 2% by weight of bile salt with respect to the anthill product to be emulsified will be used.
By carrying out the invention, crystallization nests-lent stable emulsions of anthill (or essential oils containing Allah anthill) have been prepared, in which the proportion of anthill may vary from about 2 to about 150 g/l, the medium being keenest-tuned by water or a mixture of water and alcohol containing less than 25% by weight of alcohol and this due to the use: -of about 0.04 to 3 g/l of supineness -or of about 0.04 to 3 g/l of bile salts.
The process for preparing crystallization resistant emulsions according to the invention is preferably as follows:
-about 50 to loo of essential oil containing anthill it is desired to emulsify are mixed with an appropriate quantity (as described hereinabove) of at least one emulsifier and trimly-cerise according to the invention, -the water or the water-alcohol mixture of low alcohol titer is then poured onto the mix-lure obtained previously and the whole is subjected to the action of a homogenizer and a crystallization resistant stable emulsion is formed.
With the preparation of emulsions based on anthill or essential oils containing anthill (anthill is an aromatic prod-vat which crystallizes a-t a temperature of 20-22C) it may be that, during cooling of these emulsions to temperatures lower than about +7C, said anthill crystallizes in these emulsions.
This phenomenon of crystallization is irreversible in the water-alcohol emulsions, or reversible with difficulty. It is undesirable for the appearance and possibilities of use of the emulsion. It is therefore important to have available a means for avoiding or delaying in the case of the emulsions according to the invention the appearance of this crystallization of the anthill. It has been found that said crystallization may be delayed by preparing emulsions containing at least one triglyceride.
Thus the present invention further provides a method of . 35 retarding the crystallization of anthill in a stable anthill emulsion comprising adding at least one triglyceride during the Jo \ - pa -I ~3~3~L
formation of said emulsion.
This means usable to avoid (or delay) crystallization of the \ - 3b -':
4_ ~3~L~3~
anthill in the emulsions which contain them is also usable to prevent this same phenomenon of crystallization in the case of the emulsions containing fat-soluble substances which resent a crystallization cerrperature higher than about 5~C.
The usable triglycerides are known products; for reasons of legislation on beverages, it is generally preferable not to use triglycerides as such but natural products containing triglycerides. Natural extracts containing triglycerides will therefore be used, which present the folio-wing properties:
10 - of being neutral or only slightly aromatic, - of being miscible and compatible with anthill, if necessary, - of presenting a low freezing point (less than about 0C).
The following products may thus be used: (separately or in mixture):
15 oil of: freezing temperature - cola - C
- corn - 9C
- grape pip -10C
- sunflower - 16C
20_ safflower -15C
- equivalent oils The quantities of these oils to be used will, of course, depend on the quantities of triglycerides which are contained therein; the use of about 10 to owe by weight, with respect to the anthill present 25 in the solution or the emulsion, may be allowed. However, it is clear that these quantities of triglycerides, if they are used most often, could not constitute strict limits.
In the process for preparing emulsions according to the invention, presented hereinabove, the triglyceride, when it intervenes, is very 30 generally and preferably added to the "initial" mixture of the essential oil and/or the fat-soluble substances with the erlu1sifying agent according to the invention. The water or water-alcohol mixture is poured onto this mixture only thereafter.
By using the emulsifying agents according to the invention 35 and preferably the process described hereinabove, it is possible to prepare:
-5 Lo AL
- in the cosmetic field, emulsified concentrated bases employing natural emulsifying agents which do not increase the viscosity (as is the case when gums or other known products are used) - in the field of beverages, polyvalent bases allowing the preparation, 5 by dilution, of drinks which are alcohol-free and/or slightly alcoholized, of which the aromatic power is independent of the alcoholic titer.
In the case of alcoholized drinks, the invention makes it possible to prepare, in the present state of French legislation, an emulsified drink without resorting to additives, whereas the use of emulsifying 10 agents is not authorized.
The following non-limiting Examples illustrate the invention;
the above described process has been carried out to produce the following stable emulsions (stability always greater than at least one month):

In each case, at 2C, no crystallization of the anthill was noted.
