Abstract
A process of enriching hyroxycitric acid (HCA) from Garcinia rind in which a salt-free water extract of Garcinia rind is loaded onto an anion exchange column, eluted with a metal hydroxide for release of HCA. The water-extract is then treated with a cation exchange column to make free HCA as a free acid. The water extract is loaded at a capacity of 100 to 125% of the anion exchange column and at a capacity of 50 to 90% of the cation exchange column. The HCA can be added to food products such as beverages and snack bars.
