The influence of thermal treatment on black currant juice aroma was investigated in temperature andtime ranges relevant for black currant juice concentration processes, namely, 45, 60, 75, and 90 
C.Forty-nine aroma compounds were quantified, and the thermal treatment resulted in concentrationincreases of most terpenes, aldehydes, furans, and phenols, whereas the concentration of estersslightly decreased. Higher temperatures and longer exposure times had larger effects on the aromacompounds. Odor triangle tests showed no sensory difference between pasteurized juice and juiceheated at 60 C, whereas juice heated at 90 C differed significantly from pasteurized juice. It is concluded that a 90 C thermal treatment of black currant juice, which is in the temperature range usedfor conventional evaporation of black currant juice, has an effect on the aroma and sensory properties.Keywords: Aroma; black currant juice; thermal treatment; dynamic headspace collection
