Definitions
- the present invention relates to a method for preparing Pickering emulsions obtained from biosourced particles. It relates more particularly to a process for preparing emulsions from vegetable powders, as well as the emulsions thus obtained and their uses, preferably in the cosmetics, food or road asphalt emulsion based surfaces.
- An emulsion consists of a mixture of two immiscible liquids together rendered stable over time by an emulsifier.
- the emulsions are generally divided into two categories, the so-called “water-in-oil” emulsions, where water droplets are suspended in an oily phase, and the so-called “oil-in-water” emulsions, where droplets of oil are suspended in an aqueous phase.
- Milk, butter and vinaigrette are examples of common emulsions in the agri-food sector.
- Emulsifiers also called emulsifiers, surfactants or surfactants, are compounds capable of stabilizing emulsions over time. These compounds may be of artificial origin, such as synthetic polymers, or of natural origin, such as phospholipids or proteins.
- emulsion systems can be used to increase the resistance of oils to oxidation phenomena.
- the oxidation of unsaturated fatty acids such as linoleic acid, is a complex phenomenon that comprises several phases: primary oxidation, which degrades fatty acids into hydrogen peroxide and hydroperoxide derivatives, and degrading secondary oxidation. peroxide derivatives and hydroperoxides of hydrogen to aldehyde derivatives.
- the degree of oxidation of fatty acids can be evaluated by the method of the peroxide index, which consists of a method of determination defined according to NF ISO standards. 3976, NF EN ISO 27107 or NF EN ISO 3960.

- Amphiphilic solid particles are also used to stabilize the emulsions.
- the resulting systems called Pickering emulsions, often have extraordinary kinetic stability (F. Leal-Calderon, V. Schmitt, Solid-stabilized emulsions, Current Opinion in Colloid and Interface Science, 13, 217-227 ( 2008)).
- the solid particles are capable of strongly and irreversibly adsorbing at the interface of the immiscible phases, forming a rigid and thick layer capable of permanently preventing the phenomena of destruction of the emulsions such as the recombination of the drops (coalescence).
- the application EP 2 775 862 describes the use of cocoa particles capable of stabilizing emulsions for the preparation of food products, without the use of additional emulsifiers.
- One of the disadvantages of these particles is that their application is limited to products having a chocolate taste, in order to satisfy the end consumer.

- the anchoring rate is defined as the mass ratio between the plant particles adsorbed at the interfaces and the total mass of particles used to make the emulsion.
- An anchoring rate of less than 100% reveals the presence of free particles in the continuous phase.
- the anchoring rate is determined by weighing the non-anchored particles on the surface of the drops. The decorated drops of particles are separated from the aqueous phase containing the unanchored particles by natural creaming (about 3 days). The cream is removed and the aqueous phase is removed by lyophilization to obtain the non-anchored particles which are then weighed.

- This vegetable powder is introduced into an aqueous phase (distilled water buffered at pH 7 with a 0.1 M phosphate buffer) at 2.5% by weight. This mixture is stirred with a magnetic bar for 20 minutes to obtain a dispersion.
- the dispersion is then stirred for 2 min by means of a rotor / stator type stirrer (Ultra-Turrax T25 digital) at 6000 rpm (rotation per minute).
- the oily phase (sunflower oil, 20% by weight of the total emulsion) is gradually added to the mixture once stirring is increased to 8000 rpm.

- Emulsification pressure makes it possible to play on the size of the drops and thus on the properties of the emulsions.
- Emulsification at 240 bar also makes it possible to obtain an emulsion which is very stable over time (at least 71 days), and relatively fine.
- Example 6 Measurement of Pickering Emulsion Stabilized Oil Peroxide Index.
- An oil used in the food industry must have an oxidation limit of not more than 15 meq0 2 / kg- 1 according to CODEX STAN 19-1981 This value is measured by a method of determination of the peroxide value according to standard NF EN ISO 27107.
- the peroxide number was measured for:
- Formulation A serves as a reference and allows to see the behavior of linseed oil vis-à-vis the oxidation over time.
- the advantage of formulation B is to show the impact of a mechanical stirring in oxygenated medium on the resistance of the oil vis-à-vis the oxidation. The results show that the oil according to formulation B is no longer considered edible from 48h, against 72h for formulation A.
- Formulation C shows the interest of the stabilization of the oil by means of a Pickering emulsion according to the invention.
- the results show that the resistance of an oil to oxidation can be increased by making a Pickering emulsion.
