Abstract:
A method of coating and encasing powders consisting of the salts of (âˆ’)-hydroxycitric acid in acid resistant hydrophobic polymers to produce durable and workable (âˆ’)-hydroxycitrate granulate resistant to environmental moisture, resistant to lactonization under acid environments and resistant to undesirable binding, said method comprising:(1) obtaining a salt of (âˆ’)-hydroxycitric acid or a combination of salts of (âˆ’)-hydroxycitric acid, (2) blending said salt or combination of said salts of (âˆ’)-hydroxycitric acid with a polymer wherein the polymer is selected from the group consisting of cellulose acetate phthalate, ethyl cellulose, zein, acrylic polymers, hydroxymethylpropylmethyl cellulose phthalate, polyvinyl acetate phthalate, cellulose acetate trimalleate, acrylic polymer plasticizers, polymers of poly lactic acid, polymers of glycolic acid, and mixtures thereof, (3) the resulting encased powder product of (1) and (2) is formulated into tablets, capsules, prepared dry drink mixes, prepared liquid drinkable products and edible bars.
