Method for recovering aroma concentrate from a caffeine- or theobromine-comprising food base material
Described is a method for recovering aroma concentrate from a caffeine- or theobromine-comprising food base material, such as coffee or tea, and in particular cocoa, at least comprising the steps of: introducing the food base material into an aqueous extractant and incubating the food base material at a suitable temperature and for a suitable period, substantial extraction of the aromas taking place to form an aqueous food extract, pervaporating the food extract using a hydrophobic pervaporation membrane to form a food aroma permeate, recovering the permeate to obtain the aroma concentrate. Also described are food concentrates obtainable via the abovementioned method.
