<p>This invention relates to a new soluble double salt of group IA and group IIA of (-)hydroxycitric acid of general formulas (I) and particularly (II). This invention also includes a process of preparing the soluble double metal salt of groups IA and IIA of (-)hyroxycitric acid of general formula (I) comprising preparing (-)hyroxycitric acid liquid concentrate/solid lactone thereof from Garcinia extract, neutralizing the free (-)hydroxycitric acid present in the said (-)hydroxycitric acid liquid concentrate/solid lactone (-)hydroxycitric acid with group IA metal hydroxides, displacing partially the group IA metal ions in the above salt solutions by adding group IIA metal chlorides to form soluble double metal salt of group IA and IIA of (-)hydroxycitric acid, and precipitating the said double metal salt. The instant invention also disclosed the use of the said soluble double metal salt of (-)hyroxycitric acid in beverages and other food products.</p> |
