本文以32种不同品种和产地的干、鲜红枣为原材料，经过物理指标和营养成分的检测，选取关键性的理化指标，以此为评价要素对干红枣建立隶属函数模型，以期对其品质进行较为全面的分析对比和评价。得到的主要研究结果如下：新疆地区干红枣在蛋白质含量上和山东山西河南河北等红枣主产地干红枣相似，但新疆地区，尤其以哈密地区干红枣，在糖酸比上具有较明显的优势；以单果重、蛋白质、膳食纤维以及糖酸比等关键指标作为干红枣品质统计评价要素，建立新疆干红枣隶属函数模型，能够通过该模型对一般干红枣进行评价；通过对模型中所有品种干红枣评价要素统计计算，认为新疆哈密地区干红枣在综合品质上具有较明显的优势，优于其他产地干红枣；此隶属函数模型不适用于鲜枣。

Thirty-two kinds of different dry or fresh red dates were used to detect the physical indices and nutritional composition, then the key indices were selected to establish Xinjiang dry red dates membership functional model, in order to evaluate and analyze the quality comprehensively. The results showed as follows: the protein content of Xinjiang dry red dates were similar with dates from other areas such as Shandong，Shanxi，Henan and Hebei while Xinjiang，especially Hami red dates had obvious advantages in sugar-acid ratio. The Xinjiang dry red dates membership functional model was established by using fruit weight, protein, fiber and sugar-acid ratio and so on as evaluation factors. Common red dates could also be evaluated by this model. Calculation of the evaluation factors for all kinds of the dry dates showed that Hami dry red dates had better quality than the other samples. The membership functional model is not suitable for fresh dates.
