果啤与啤酒组分差异比较研究

采用气相色谱和高效液相色谱的分析方法,分析了市售同一品牌菠萝果啤、啤酒的风味成分、有机酸、糖的组成及含量,结果表明,果啤中酯含量类物质的种类相对普通啤酒丰富,组成协调,高级醇含量低。有机酸含量果啤高于啤酒,柠檬酸积累较多。果啤中蔗糖消耗大,而果糖和葡萄糖含量有所升高。

Study on different compositions of fruit beer and beer

The contents of flavor substance,organic acids and sugars were analyzed by Gas Chromatography and High Performance Liquid Chromatography for fruit beer and conventional beer produced by the same company.It was shown that the fruit beer contained more flavors and had better constitution proportions compared with conventional beer.The content of long-chain alcohol is lower in fruit beer,while the contents of organic acids were higher,especially for citric acid.Besides,the content of sucrose was decreased in fruit beer with an increasing in the contents of fructose and glucose.
