苏北废黄河三角洲是中国东部沿海研究海陆交互作用的重要区域,在该区域开展槽型钻和基坑剖面调查,同时采集泥炭层样品进行^(14)C测年,结果显示废黄河三角洲区域浅表主要分布以淤泥质黏土、黏土或砂黏互层的“千层饼”状沉积物为主的潮坪-潟湖-砂坝相沉积层,以及以细砂、粉砂等砂质为主的废黄河沉积层,其形成时间分别为5—7 ka B.P.(中全新世早—中期)及12—19世纪黄河夺淮期间。因此认为全球性气候变化是废黄河三角洲区域沉积环境演变的主导因素,中全新世早—中期全球性的气温升高和降雨增多造成入海沉积物的增加,形成了全区广泛分布的以潮坪、潟湖、砂坝等微地貌为主的海陆交互相沉积;12—19世纪黄河夺淮期间携带大量泥沙入海,与人类改造活动共同控制了废黄河三角洲现代地貌的形成。

白酒中的非挥发性风味物质对白酒的滋味和品质有重要影响。截至目前,对酱香型白酒中非挥发性风味物质的研究很少,且大多集中在部分非挥发性有机酸类(如乳酸、长链脂肪酸)。因此,全面解析酱香型白酒中的非挥发性风味物质及关键风味化合物组成差异,对全面深入解密酱香型白酒具有重要意义。本研究采用水浴浓缩结合氮吹、高效液相色谱(High performance liquid chromatography,HPLC)、高效液相色谱串联质谱法(High performance liquid chromatography-mass spectrometry-mass spectrometry,HPLC-MS/MS)对贵州仁怀产区酱香型白酒中的非挥发性有机酸及酚酸类物质进行定性定量分析,并结合多元统计分析方法对不同酱香型白酒样品进行差异分析,试图探索出可以区分不同酱香型白酒的分析方法。结果表明,在不同生产工艺酒样中各目标化合物种类及含量存在差异,在坤沙酒中检出14种非挥发性有机酸和4种酚酸类物质,翻沙酒样中检出13种非挥发性有机酸和1种酚酸类物质,碎沙酒样中检出14种非挥发性有机酸及1种酚酸类物质;已检出的各非挥发性风味物质含量均在坤沙酒样中最高,其中乳酸、马来酸、富马酸、阿魏酸含量在坤沙酒中高出翻沙与碎沙两种酒样几倍,且只在坤沙酒中检出原儿茶酸等3种酚酸,可利用上述7种非挥发性风味物质区分坤沙酒与翻沙、碎沙酒;根据PCA及OPLS-DA分析,构建了坤沙、翻沙及碎沙3种大曲酱香型白酒的鉴别模型,可基本实现3种工艺酒样的鉴别;VIP分析筛选出的4种潜在差异物质可用于区分3种工艺,即乳酸、油酸、亚油酸及棕榈酸,乳酸VIP值(3.1343)最高,进行单因素方差分析发现,4种潜在差异物质在坤沙、碎沙和翻沙3种酒样中差异显著(P<0.05)。
