稻草是传统茶油压榨过程中用于包裹茶籽粉的材料。为了给稻草包饼材料对茶油感官品质影响的研究提供参考依据,分别以湖南双峰产的茶油及添加了不同稻草压榨的自制茶油为供试的茶油样品,对其色差值、关键香气成分与感官属性进行了检测和评价。检测结果表明:双峰茶油的关键香气成分依次为辛醛、（E）-2-癸烯醛、（E）-2-壬烯醛和壬醛,3种添加稻草自制的茶油其关键香气成分均为（E）-2-癸烯醛、苯乙醛和壬醛,与双峰茶油的色泽和香气最接近的是添加了青稻草的自制茶油;分别以色差值、关键香气成分与感官属性建立了PLS模型,该模型对茶油感官品质具有较好的预测能力。研究结果表明,青稻草包饼材料对茶...

As a packing material,straw is used to wrap Camellia oleifera seed powder in traditional pressing process of C.oleifera oil.In order to provide some references for studying effects of straw packing material on sensory quality of C. oleifera oil,chromatism value,key aroma components and sensory attributes of a C.oleifera oil sample from Shuangfeng of Hunan and laboratory made C.oleifera oil samples which added with straws were determined and evaluated.The results showed that key aroma components in Shuangfeng C.oleifera oil were octanal,(E)-2-decene aldehyde,(E)- 2-nonenal and nonanal,and those...
