为寻求适合莲藕食品生产的优良鲜藕品种,测定了湖北3个莲藕品种的理化特性,并利用质构仪、GC-MS和电子鼻研究其质构特性和风味物质。结果表明,3个品种之间的理化特性除了总纤维含量外均有显著差异,鄂莲5号的质构特性优于鄂莲3号和4号;GC-MS检测出鄂莲3号、4号、5号的风味物质分别为35,28,40种,主要是酯类、烷烃类和芳香烃类,其中鄂莲4号的28种风味成分是3个莲藕品种共有的;鄂莲5号的风味物质种类和含量明显多于鄂莲3号和4号,特别是酯类物质含量较多,占总检出物质的68.8%;电子鼻检测出3种莲藕的主成分差异与GC-MS检测出3种莲藕的风味物质差异结果具有一致性。综合评价得出,鄂莲5号是3个莲藕品种中...

Phy-chemical properties and flavor substances of the three varieties of Hubei lotus root were studied by electronic nose and GC-MS. The results showed that there were significant differences in the physical and chemical properties except the total fiber content among the three hybrid varieties, and texture properties of the hybrid variety NO.5 of lotus root were better than the hybrid varieties NO.3 and NO.4. Detection of flavor substances showed that 40 kinds of flavor substances were detected in NO.5, that 35 kinds of flavor substances were detected in NO.3, that 28 kinds of flavor substance...
