| 摘 要： | 用气相色谱法研究儿茶素消除三甲胺、硫化氢、吲哚气味的机理，实验显示，消臭效果L－EGCG＞L－EGC＞L－ECG＞L－EC（单位重量），随时间的延长消臭率逐渐升高，消臭后儿茶素吸光值降低和纸上层析新斑点出现，认为茶素存在化学消臭，没食子酰基可能增强消臭能力。

| Abstract: | The deodorization of cateehins to trimethylamine,H2S and indol with gas chromatography has been studied in this paper.Our expriments show that the deodorizing effects of catechins was L-EGCG>L- EGC> L- ECG > L- EC, and the deodorizing rate of catechins increased with time of deodorization while cate-chins OD ralus decreased after deodorizing and new spot appeared in peper chrornatogrurn,The condusion is ma-de accordingly that atechins can be used t0 deodorize in a chemical way and gallamyl in catechins may inhancedeodorization. |
