为探究滇红对戚风蛋糕香气物质的影响,夯实茶烘焙食品开发的理论基础,采用GC-MS/GC方法对滇红戚风蛋糕的香气物质进行研究。结果表明,滇红戚风蛋糕和滇红茶叶拥有共同的香气物质:顺-2-己烯-1-醇、芳樟醇及芳樟醇氧化物、水杨酸甲酯、香叶醇、苯乙醇、橙花叔醇,而原味戚风蛋糕中不含有这些香气物质,滇红戚风蛋糕经烘焙后,大多数香气物质含量降低:芳樟醇及其氧化物II、III,橙花叔醇、反-2-己烯醛等;部分香气物质一定幅度增加。说明滇红茶粉赋予了戚风蛋糕滇红的香气特征,烘焙工艺对滇红戚风蛋糕中茶香风味物质的组成及含量有较大影响。

Abstract:In order to investigate the effect of Dianhong Tea on the aroma components of Chiffon cake and strengthen the theoretical basis for tea baking food development,GC-MS/GC method was used to study the aroma components of Dianhong Chiffon cake.The results showed that Dianhong Tea Chiffon cake and Dianhong Tea had the same aroma components: (Z)-2-Hexen-1-ol, Linalool and its oxides, α-Terpineol, Limonene, Methyl Salicylate,Nerol, Geraniol, Phenylthanol, Nerolidol.However, the original flavor Chiffon cake did not contain these aroma components.After baking, the content of most aroma components decreased, including Linalool and its oxides II, III,Nerolidol, Trans-3-Propyalacrolein, etc.A certain amount of aroma components increased.It indicated that Dianhong Tea powder gave Dianhong Tea Chiffon cake the aroma characteristics.Besides,the baking process had a great influence on the composition and content of the tea aroma components in Dianhong Tea Chiffon cake.

茶叶具有独特的天然风味,将茶加入到烘焙食品中,可以赋予烘焙食品特殊的茶香风味及健康属性。茶叶中的成分对烘焙食品的影响是多方面的。周裔斌[1]在焙烤食品中添加了茶多糖,结果显示茶多糖的加入可以提高面包的发酵速度,同时适量添加茶多糖还能够延缓面包和蛋糕中淀粉的老化回生,改善面包和蛋糕的弹性、回复性、咀嚼性,提高感官品质。……
