Such unit operations include pressurization using hydraulic press means, steam distillation, fractional distillation, supercritical carbon dioxide extraction, volatile solvent extraction and/or charcoal column separation means. Also described is apparatus for carrying out such processes as well as the products produced using such processes and organoleptic uses of such products. Also described are compositions comprising (a) such tastands in admixture with (b) an eatable having a bitter and/or metallic taste.
