Citrus juice sacs are important portion of the citrus juice sacs drink, its quality determines series of sensory index of the citrus juice sacs drink. Valencia Orange, Gannan navel orange, Satsuma orange and Xiangxi ponkan were selected as research materials, the physicochemical indexes of these four cultivars were determined, and sensory evaluation was also investigated. The results showed that the VCcontents were 20 ~ 45 mg /100 m L of these citrus juice sacs, and the highest level of VCin Gannan navel orange was observed. The content of soluble solid in Xiangxi ponkan was the highest among these citrus cultivars.A great difference on the color was observed beween the two cultivars except for Xiangxi ponkan and Gannan navel orange. The sensory evaluation results showed that Xiangxi ponkan had the best sensory attribute.
