Patent ID: 8114910

Claim:
A method of making a composition comprising fulvic acid as an active ingredient which includes the steps of providing a carbohydrate and subjecting the carbohydrate to wet oxidation to produce a reaction product comprising acidic components including fulvic acid in solution and treating the reaction product to remove substantially all of the acidic components having a molecular weight exceeding 20,000 Daltons; wherein the wet oxidation includes the steps of producing a solution or suspension of the carbohydrate in water and subjecting the solution or suspension to elevated temperature and pressure conditions to oxidize the carbohydrate; where elevated temperature is in the range 100 to 300 degrees centigrade and the pressure is such that boiling of the water is prevented; and wherein the carbohydrate is selected from the group consisting of a monosaccharide, a disaccharide, and a polysaccharide.
