Problems solved by technology

[0005] Although water is ubiquitous in plants, many plant-derived bioactive molecules (e.g., vitamins, antioxidants, natural anti-inflammatory agents, etc.) are poorly or insoluble in water, limiting extraction yields as well as the resulting extracts the quality of (e.g. in terms of integrity and stability)

Embodiment Construction

[0075] In the following detailed description of the embodiments of the present invention, numerous specific details are set forth to provide a more thorough understanding of the specification. It will be apparent, however, to one skilled in the art that this description may be practiced without these specific details. In other instances, well known features have not been described in detail to avoid unnecessarily complicating the description.

[0076] figure 1An example of the extraction method according to the present description is shown, which also includes the additional step of freeze-drying the emulsion obtained by sonication. The mixture to be emulsified comprises water (1), vegetable source (2) (ie turmeric root), surfactant (3), lipophilic compound (4). The mixture is contained in a container (5) and the emulsification of the mixture includes a sonication step by means of an ultrasonic rod (6) capable of emitting ultrasonic waves (7). Sonication of the mixture lead...

Abstract

The present description relates to a method for extracting at least one substance of interest, the method comprising the following steps: - providing an admixture comprising water, a source comprising the at least one substance of interest or at least one precursor thereof, at least one surfactant and at least one lipophilic compound; - the emulsification of the admixture, leading to the formation of an emulsion; wherein the emulsion comprises: - a continuous aqueous phase; and a discontinuous lipidic phase comprising the at least one lipophilic compound, the at least one surfactant and at least one substance of interest extracted from the source during the emulsification; wherein the method further comprises the addition of at least one cryoprotectant to the admixture and the lyophilisation of the emulsion.

Description

technical field [0001] The present invention relates to a method for extracting at least one substance of interest, an emulsion produced by the method and the use of the emulsion. This description applies especially, but not exclusively, to the fields of food processing, cosmetics and pharmaceuticals, and the field of perfumery. Background technique [0002] Natural substances, for example of plant, animal or mineral origin, are of increasing interest in many fields. In fact, a certain number of industrial sectors (cosmetics, pharmaceuticals, food processing, nutraceuticals, probiotics) are shifting to incorporating plant-derived molecules in their formulations. Adding value to these natural active ingredients represents a huge economic potential for the development of the food processing, cosmetic and pharmaceutical sectors. [0003] To add value, natural compounds such as bioactive compounds, i.e. compounds with biological activity, can first be isolated from their plan...
