Abstract:With xylitol as sweetener，pomegranate juice was mixed with fresh milk to get lactic acid bacteria fermentation ，and then xylitol- pomegranate juice yogurt was made. Pomegranate juice，xylitol and additive amount of starter culture were determined as the three factors by single factor experiment，and then the optimal fermentation conditions were determined by orthogonal tests. Results showed that the optimal concentrations of pomegranate juice， xylitol，and starter culture inoculation were 12 %，6 %，and 5 %，respectively. The optimal fermentation time was 6 hours；and the optimalfermentation temperature was 42 ℃. The yogurt made with the optimal conditions was fruity，moderately sweet and sour，taste fine and smooth，and has slight pomegranate juice scent.
