Abstract
Compositions for adsorbing sulfur-containing compounds and eliminating or reducing odors associated with the ingestion of foods or medicines causing sulfur odor, such as garlic and onions, contain a metal complex of a substrate and a ligand. The complex may be contained in a carrier, such as a silica gel, and has low solubility in an aqueous environment. The ligand of the compositions may comprise an amino acid containing sulfur, nitrogen, or a carboxylic acid, such as cystine, and the substrate is a metal which may be copper, zinc, or iron.
