実験手順

50 g equivalent of the hydroxy citric acid—potassium salt solution from Example 2 was taken into a glass beaker fitted with a stirring arrangement. To this solution, 43 g of the dried calcium salt from Example 1 was added and the mixture was stirred to yield a clear solution. The resultant solution was spray dried to yield a salt of hydroxycitric acid with the following analysis: potassium content 11% to 18%, calcium content 5% to 12%, structural moisture 3% to 5% and hydroxycitric acid content 70% to 76%. The sodium content was less than 0.5% and lactone less than 0.5%. The combined salt has a solubility of 5 g in 100 mL of deionized water at room temperature. This salt composition is tasteless and white in color. A solution of 5 g in 100 ml of de-ionized sterile water was subjected to an accelerated storage study chamber for 2 months. After 2 months it was observed that the salt did not precipitate out. The solution retained its clarity. Therefore, it can be safely concluded that, after dissolution in water, the salt composition does not decompose during storage.
