高多酚含量植物提取物对4种典型臭味化合物除臭性能的影响
Deodorizing Effect to Four Typical Odor Compounds by Several Plant Extracts with High Polyphenol Content
摘要
Abstract
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 evaluation of these crude extracts for the deodorization of these typical odor compounds.A certain concentration of odor compounds were added into 100 mL glasse bottles with a rubber stopper and then some amount of plant extracts were injected respectively.Eliminating effects of samples to the four odor compounds were investigated by GC-MS and sensory evaluation after shocking and incubating 30 min at 40 ℃.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 conclusion,polyphenolic content of plant extracts and deodorizing effect were correlated to a certain degree through all these studies.关键词
