Abstract
The present invention relates to a process for the preparation of compositions having a high concentration of bioactive compounds (BACs), as well as to the use of a device for implementing said process, comprising the percolation of halogenated solvents, in particular hydrofluorocarbons and hydrofluoroolefins, through a solid matrix comprising one or more bioactive compounds and the subsequent evaporation of the halogenated solvent in an expansion chamber containing the substance to be enriched. The invention also relates to BAC-enriched compositions thus obtained and to food, cosmetic, nutraceutical, or pharmaceutical products containing them.
Claims13
Process for the preparation of a composition containing one or more bioactive compounds comprising the following steps:
- percolating a halogenated solvent in the liquid phase through a solid material containing at least one bioactive compound under conditions of temperature and corresponding condensation pressure of said halogenated solvent;
- collecting the percolated halogenated solvent in an expansion chamber equipped with suction means under conditions of evaporation temperature and corresponding pressure of said halogenated solvent such that the solvent passes into a vapour phase;
- and
- aspirating the halogenated solvent in the vapour phase away from the expansion chamber,
- the process being characterised by the fact that said expansion chamber is pre-loaded with a lipid substance such that, when the solvent is aspirated, at least one bioactive compound is released into the lipid substance to give a composition comprising said bioactive compound.
Use according to any one of the preceding claims, wherein said feeding means of the solvent to said first chamber comprise a storage tank 6 of said solvent, preferably wherein said means for recondensing the solvent also comprise means for diverting said recondensed solvent to said storage tank.
Use according to any one of the preceding claims, wherein said first chamber 1 is provided with a removable basket 2 for containing said solid material, and optionally with heating means arranged near a lower end of said chamber 1.
Use according to any one of the preceding claims, wherein the lower portion of said second chamber 3 is provided with a tap 14 for recovering the lipid substance enriched with the at least one bioactive compound.
