蜂蜜产地特检测方法的研究.pdfVIP

摘 要 摘 要 本文共包括五部分，第一章是综述，简述了产地特征的研究状况、检测方法的研究 状况以及进行蜂蜜产地特征的必要性和研究内容。 第二章中采用湿法消解-原子吸收光谱法和 721 分光光度计对不同品种的蜂蜜中钾、 钠、镁、铁、钙、铜、锌、锰、铬、镉、铅和磷等若干元素进行含量测定，并引进特征 性因子，并做出若干元素含量比例曲线分布图，发现样品中有些元素含量存在显著性差 异，有些则不存在，从而为蜂蜜产地来源及品质特征鉴定提供了可靠的科学依据。 第三章利用两种不同的红外光谱仪测定不同品种蜂蜜，并对所获得的红外指纹图谱 进行特征峰指认和对比分析，结果发现不同品种的蜂蜜红外吸收频率、相对强度存在一 些差异。 第四章利用 721 型分光光度计对不同种蜂蜜中的果糖、蔗糖和还原糖进行测定，通 过含量比例图中找到差异，从而得出不同的植物类型、气候、蜂群及取蜜时间等对蜂蜜 中糖含量有很大影响。 第五章中尝试建立不同品种蜂蜜气相色谱指纹图谱，通过对谱图分析找出差异，从 而为鉴别不同产地来源的蜂蜜提供依据。 关键词 蜂蜜 产地特征 方法研究 I Abstract Abstract This paper consists of five chapters.The first chapter is summarize.In the first chapter, the concept of the development at home and abroad 、the relevant literature about origin characteristics、the necessity of the research about characteristic of honey and the study in this paper. In the second chapter, the content of Potassium, Calcium, Sodium, Magnesium, Copper, Zinc, Iron, Manganese, Chromium, Cadmium, lead and Phosphonium in different varieties honey were determined and analysed with Wet digestion-atomic absorption spectrometry and 721 spectrophotometer. and the introduction of characteristic factor, the proportion of curves to make a number of element content distribution, It is found that there is significant difference in some elements of honey, and the difference of some other elements is not significant. It can provide science foundation to evaluate the production area and to identify the characteristic for honey. In the third chapter, Two different infrared spectroscopy are used to determine different varieties of honey , characteristic peaks in IR fingerprint spectr are identified
