Abstract: An improved, reduced calorie, high base content chewing gum composition possesses a greater, more intense initial flavor impact of increased duration. The method of preparation utilizes highly fractionated or rectified flavor oils from which are removed the terpene and sesquiterpene components resulting in an enhanced and sustained flavor release from the gum base. The deterpenated oils have a lesser affinity for the gum base allowing for the use of higher gum base levels for the reduction of calories without the flavor oils being trapped therein. The sustained flavor release is also improved by the complete or partial renewal of several bitter tasting components previously associated with the oils.

Abstract: A process for recovering volatile aroma components from aroma-bearing vegetable materials such as roast and ground coffee. A carrier gas is passed through the vegetable material to strip aromas therefrom, and the resulting aroma-laden gas is contacted with a cryogenic liquid such as liquid nitrogen to condense the aromas from the gas. The carrier gas has a boiling point equal to or lower than that of the cryogenic liquid. Because the efficacy of the condensation step is substantially independent of the gas flow rate, the optimum gas flow rate for effective stripping may be used without loss of aromas at the condensation step.
