摘　　要：目的:以龙井茶、苹果皮、葡萄皮籽、柿子叶、山楂和柿子皮6种较高多酚含量的植物为原料,提取其有效成分,测定其多酚含量,分析各提取物对4种臭味化合物——异戊酸、三甲胺、氨气和吲哚的除臭效果,多酚物质含量与除臭效果的相关性。方法:样品经干燥、粉碎后的水提物,以福林酚法检测总酚含量;将各提取物与臭味化合物置于除臭瓶中,采用GC-MS及感官评定法分析除臭效果。结果:龙井茶提取液的总酚含量最高(124.28 mg/g),柿子皮的最低(0.24 mg/g)。各提取液对上述4种臭味化合物均有不同程度的吸附效果,尤其对三甲胺和吲哚的消除能力显著,其中山楂和龙井茶提取物对三甲胺的除臭率分别为100%和65.4%,龙井茶提取物对吲哚除臭率为68.2%;各提取物对氨气的除臭效果较低,最高的龙井茶提取物仅为19.8%;不同含量柿子叶提取物总酚含量与异戊酸、三甲胺和吲哚的脱臭效果相关性分析发现,两者有一定相关性,相关系数为0.93。Objective： Six plants with high polyphenol content were selected for deodoring effect on isovaleric acid, trimethylamine, ammonia and indole. Method： The plant materials were dried at a low temperature and then grinded. The active ingredients of each sample powder were extracted with warm water combined with ultrasonic vibration. The total phenolic content of the plant extracts was determined with Folin-denis reagent .The second part of the study was evalua- tion of these crude extracts for the deodorization of these typical odor compounds. A certain concentration of odor com- pounds were added into 100 mL glasse bottles with a rubber stopper and then some amount of plant extracts were inject- ed respectively. Eliminating effects of samples to the four odor compounds were investigated by GC-MS and sensory eval- uation after shocking and incubating 30min at 40~C. Result： （1） The highest yield of polyphenols was from tea extract, while persimmon skin extrat showed the minimum content. However, there were significant differences between them. （2） Deodorizing ability of crude extracts to the four compounds exhibited different levels. Especially, eliminating capacity to trimethylamine and indole was significantly high, but all these samples had little effect on the ammonia removal. In con- clusion, polyphenolic content of plant extracts and deodorizing effect were correlated to a certain degree through all these studies.
