葡萄酒作为一种安康时髦的饮品,具有抗氧化性、抗肿瘤和舒化血管等功效,广受花费者爱好。最近几年来,我国对葡萄酒的出口量逐年上升,但今朝对葡萄酒的原产地信息熟悉仍比拟隐约,也缺少相干的检测办法。为了顺应国际商业的成长,标准出口葡萄酒市场,对葡萄酒停止原产地等特别身份信息辨别,法语论文范文,本文重要以法国葡萄酒为样本,对波尔多产区的葡萄酒做了以下几方面的研究:起首,经由过程镧系元素、中等质量数组分及挥发性组分,分离对应运用电感耦合等离子体质谱仪、液相色谱四级杆飞翔时光质谱联用仪及气相色谱质谱联用仪对其停止了检测办法的树立、组分的组学研究,并经由过程偏最小二乘法树立猜测模子。实验成果发明:雷同产区间的葡萄酒存在必定的类似聚类,每种检测办法都在分歧水平上对法国波尔多地域的葡萄酒停止了精确辨别。固然每种办法都有误判能够性,然则将三种辨别模子的成果停止比较参照,综合考量其辨别成果,就可以对原产地信息停止较好的判定。其次,考核了该模子对搀假制假葡萄酒的辨别机能,法语论文,成果注解:模子对搀假制假亦有必定辨别才能,但在高比例勾兑搀假时没法分离出是搀假制假照样产地信息制假。剖断的可托度得分与搀假比例呈负相干,随搀假比例的增长而降低。最初,经由过程核磁共振仪对酿造葡萄酒所用的葡萄种类及葡萄采摘年份的辨别停止了初探。固然试验样本较少,但从成果中亦能看出办法具有可行性。 Abstract: Wine as a Ankang fashionable drinks, with antioxidant, anti tumor and the effect of the blood vessels, and so on. In recent years, China's export volume of wine has increased year by year, but at present the country of origin of the wine is still relatively vague knowledge, and lack of coherent detection method. In order to comply with the growth of international business, standard export wine market, the special identity information such as the origin of the wine, this paper is important to the Bordeaux region of wine made the following aspects: first, through the process of La series, medium quality array and volatile components, separation corresponding application inductively coupled plasma mass spectrometry, liquid chromatography coupled with gas chromatography mass spectrometry and gas chromatography mass spectrometry. Experimental results have been found: there is a certain kind of similar clustering in the same region of the same region, each test method is different level to the Bordeaux region of France to stop the precise identification of wine. Although each approach has a miscarriage of justice, but the results of the three types of identification of the results of the comparison of reference, the comprehensive consideration of their identification results, you can stop the good judgment of origin information. Secondly, the assessment model of counterfeiting Wine adulterated discriminative function of the results of note: the model of counterfeiting also must have ability to identify adulterated, but in high proportion not isolated by blending adulterated adulterated fake origin information is so fake. Split off the credibility of the score was negatively coherent and adulterated ratio, with the increase in the proportion of lower adulteration. Initially, a preliminary study on the identification of grape varieties and grape picking year of the wine by the nuclear magnetic resonance instrument. Although the test sample is small, but it can also be seen that the method is feasible. 目录: 摘要 4-5 Abstract 5 第1章 文献综述 10-20 1.1 引言 10 1.2 葡萄酒 10-13 1.2.1 波尔多的葡萄酒 10-12 1.2.2 葡萄酒的保健功能 12 1.2.3 假葡萄酒的种类与危害 12-13 1.3 葡萄酒真伪鉴定技术探讨进展 13-16 1.3.1 感官略论 13 1.3.2 常规理化检验 13 1.3.3 原汁含量的测定 13 1.3.4 花色苷含量的测定 13-14 1.3.5 红外光谱技术鉴别 14 1.3.6 核磁共振法鉴别 14-15 1.3.7 同位素比值法鉴别 15 1.3.8 电子鼻/舌仿生技术 15 1.3.9 质谱技术 15 1.3.10 生物技术 15-16 1.3.11 代谢组学在葡萄酒特殊身份信息鉴别中的适用性 16 1.4 异同表达略论 16-18 1.4.1 倍性变化 16 1.4.2 T 检验 16-17 1.4.3 SAM 法 17 1.4.4 Bonferroni 校正法 17 1.4.5 Sidak 校正法 17 1.4.6 Hochberg 法 17-18 1.4.7 BH 法 18 1.5 本文的探讨意义与主要内容 18-20 第2章 基于镧系元素测定对葡萄酒产区进行追溯 20-31 2.1 材料与措施 20-22 2.1.1 仪器与试剂 20 2.1.2 样品的采集与贮藏 20 2.1.3 样品的制备 20 2.1.4 ICP-MS 略论 20-21 2.1.5 QA/QC 21 2.1.6 数据处理与统计略论 21-22 2.2 结果与讨论 22-30 2.2.1 前处理措施的确定 22 2.2.2 单因素方差略论 22 2.2.3 主成分略论 22-26 2.2.4 建立预测模型 26-28 2.2.5 波尔多产区的适用性探讨 28-29 2.2.6 真伪鉴别的盲样测试 29-30 2.3 小结 30-31 第3章 基于液相色谱四级杆飞行时间质谱联用技术的葡萄酒组学鉴定探讨 31-39 3.1 材料与措施 31-32 3.1.1 仪器与试剂 31 3.1.2 样品的采集与贮藏 31 3.1.3 样品的制备 31 3.1.4 色谱-质谱条件 31-32 3.1.5 数据处理与统计略论 32 3.2 结果与讨论 32-38 3.2.1 色谱-质谱条件的选择 32-33 3.2.2 特征化合物提取的参数选择 33 3.2.3 特征化合物的筛选 33-34 3.2.4 主成分略论 34-36 3.2.5 建立预测模型 36-37 3.2.6 真伪鉴别的盲样测试 37-38 3.3 小结 38-39 第4章 基于气相色谱质谱联用技术的葡萄酒组学鉴定探讨 39-47 4.1 材料与措施 39-40 4.1.1 仪器与试剂 39 4.1.2 样品的采集与贮藏 39 4.1.3 样品的制备 39 4.1.4 色谱-质谱条件 39-40 4.1.5 数据处理与统计略论 40 4.2 结果与讨论 40-46 4.2.1 色谱-质谱条件的选择依据 40 4.2.2 特征化合物的提取与筛选 40-42 4.2.3 单因素方差略论 42-44 4.2.4 主成分略论 44 4.2.5 建立预测模型 44-46 4.2.6 真伪鉴别的盲样测试 46 4.3 小结 46-47 第5章 核磁共振对波尔多葡萄酒的葡萄酒品种及年份初探 47-59 5.1 材料与措施 47 5.1.1 仪器与试剂 47 5.1.2 样品的采集与贮藏 47 5.1.3 样品的制备 47 5.1.4 核磁共振条件 47 5.2 结果与讨论 47-58 5.2.1 葡萄品种鉴别 47-53 5.2.2 葡萄年份鉴别 53-58 5.3 小结 58-59 第6章 结论与展望 59-61 6.1 结论 59 6.2 探讨中存在的一些问题与展望 59-61 致谢 61-62 参考文献 62-68 攻读学位期间的探讨成果 68 |
