摘要: 汁胞是柑橘汁胞饮料中重要的组成部分,其品质决定了柑橘汁胞饮料的色泽、口感等一系列感官指标。本文以夏橙、赣南脐橙、温州蜜柑和湘西椪柑四种柑橘作为研究对象,比较了四种不同柑橘汁胞可溶性固形物含量、可滴定酸、汁胞柄长度、色度等理化指标的差异,并对不同品种的柑橘汁胞进行了感官评定,综合二者进行评价。结果表明,四个不同品种柑橘汁胞中VC含量在20~45mg/100m L之间,其中赣南脐橙的VC含量最高,湘西椪柑可溶性固形物含量最高;除湘西椪柑与赣南脐橙之外,四个品种两两之间色度差异较大;感官分析结果表明湘西椪柑汁胞具有最良好的感官特征。Abstract: 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.
