Definitions
- the present invention relates to stable aqueous emulsions of essential oils which can be used in particular for the preparation of flavoring concentrates for food products, in particular non-alcoholic drinks and confectionery or concentrates for cosmetics.
- sucroglycerides or sucroesters it is known to use sucroglycerides or sucroesters to prepare aqueous emulsions of essential oils.
- aqueous emulsions which may contain up to 15 to 20% of essential oils and a fluid mixture of sucroglycerides and of a fluid rapeseed oil for example ( sucroglyceride / fluid oil weight ratio of 30/70 to 50/50) in an amount expressed as sucroglycerides representing from 40 to 60% of the weight of the essential oil; sufficient water is present to complete the emulsion to 100% by weight.
- Czech patent n ° 188.576 relates to food perfume powders prepared from an aqueous emulsion of lemon oil for example, obtained using a sucroester or a monoglyceride and carboxymethylcellulose as stabilizer.
- the amount of monoglyceride or sucroester used corresponds to approximately 50% of the weight of oil.
- Such emulsions have the major drawback of requiring the presence of too large a quantity of sucroglycerides or of sucroesters.
- Patent FR-A-2 483 455 describes stable emulsions of essential oils comprising at least essential oils, an emulsifying agent such as a sucroglyceride and water.
- these emulsions also contain a vegetable gum such as gum arabic in particular.
- a vegetable gum such as gum arabic in particular.
- the quantity of vegetable gum necessary to obtain good stability of these emulsions is very large.
- essential oils means mixtures of various more or less volatile products derived from plant species by an appropriate physical process such as distillation carried out in a stream of water vapor, enfleurage, maceration, solvent extraction and expression. They are also called “essences”.
- essential oils we can cite: the essence of angelica roots, the essence of anise, the essence of cinnamon, the essence of lemongrass, the essence of coriander, the essence of garlic, onion essence, bitter almond essence, juniper essence, ginger essence and all citrus essences like lemons, tangerines, oranges, grapefruits, etc. ..
- sucrose denotes the mixture of products obtained by transesterification of sucrose and natural or synthetic triglycerides; this mixture contains monoglycerides, diglycerides, unaltered triglycerides (in small quantities), monoesters and diesters of sucrose.
- triglyceride means one or more triglycerides of saturated or unsaturated aliphatic fatty acids having at least 12 atoms, preferably 14 to 20 carbon atoms.
- triglyceride obtained by reaction of glycerol and fatty acids but it is more advantageous for economic reasons to use natural triglycerides which are mixtures.
- triglycerides suitable for the invention examples that may be mentioned include lard, tallow, peanut oil, butter oil, cotton seed oil, linseed oil, coconut oil, olive oil, palm oil, grape seed oil, fish oil, soybean oil, castor oil, oil copra.
- fatty acid triglycerides containing no more than one double bond are used and if necessary, they are subjected to hydrogenation in order to reduce the number of unsaturations.
- palm sugar, lard, coconut oil, tallow sugar are preferably used. They are in the form of more or less consistent pasta and differ commercially by their melting point:
- palm oil sucroglycerides are chosen.
- sucroglycerides can also be in powdered form by placing on a support such as skim milk, whey, sucrose, maltodextrin, starch, polysaccharides ...
- sucrose monoesters and diesters obtained by the action of sucrose on a fatty acid which may contain from 12 to 20 carbon atoms (of the same type as that used to prepare sucroglycerides) or else by separation with within the mixture (called “sucroglycerides”) resulting from the transterification of sucrose and natural or synthetic triglycerides.
- the sucroesters can be in pasty form or in pulverulent form by placing on a support of the same type as those mentioned above concerning the sucroglycerides.
- the stable emulsions of essential oils which are the subject of the invention can be prepared by various methods.
- a first method of preparation consists in dispersing the sucroglyceride or the sucroester in water at a temperature of the order of 20 to 60 ° C., adding the xanthan gum with stirring until a solution is obtained and then dispersing the essential oil in the aqueous mixture by homogenization.
- Stable aqueous emulsions of essential oils can be used for the preparation of food flavoring concentrates (soft drinks, confectionery) or concentrates for cosmetics.
- sucroglyceride or the sucroester is dissolved in water at 80 ° C. with stirring at 700 rpm.
- the xanthan gum is then poured in rain; stirring is left for 15 minutes at 700 revolutions / minute.
- the solution obtained is kept for at least 2 hours at room temperature.
- sucroglyceride or the sucroester is dissolved in water, at 80 ° C. with stirring at 700 rpm; stirring is still maintained for 15 minutes at 700 revolutions / minute.
- the solution formed is left to stand at room temperature for at least 2 hours.
- Orange essential oil is added to the sucroglyceride or sucroester solution with shaking with ULTRA TURRAX T45N.
- the xanthan gum solution is introduced into the mixture of essential oil and sucroglyceride or sucroester, then the whole is homogenized for 40 seconds with ULTRA TURRAX T45N at maximum speed.
- the prepared emulsions are stored at different temperatures (ambient, 4 ° C and 50 ° C) in 100 ml graduated cylinders.
- Emulsions are considered stable when the code assigned to them is 1 or 2.
- Orange essential oil emulsions are prepared according to procedure No. 1 or No. 2.
