以铁观音加工过程中主要生化成分为研究对象，测定生产过程中各工序在制品的咖啡碱、茶多酚、游离氨基酸含量。结果表明：加工过程中铁观音的咖啡碱、茶多酚、游离氨基酸含量呈规律性变化。炒青是临界加工工序，其高温致使酶失活变性铁观音停止发酵，铁观音内含物质在炒青工序被固化。在此后揉捻、烘干等工序中咖啡碱、茶多酚含量趋于稳定，基本不再发生变化，游离氨基酸含量缓慢减少。
이철관음가공과정중주요생화성분위연구대상，측정생산과정중각공서재제품적가배감、다다분、유리안기산함량。결과표명：가공과정중철관음적가배감、다다분、유리안기산함량정규률성변화。초청시림계가공공서，기고온치사매실활변성철관음정지발효，철관음내함물질재초청공서피고화。재차후유념、홍간등공서중가배감、다다분함량추우은정，기본불재발생변화，유리안기산함량완만감소。
In this paper ,study on the main biochemical composition in Tie-guanyin machining process and measure the content of caffeine ,tea polyphenols ,free amino acids in the different processes .The results showed that the content of caffeine , tea polyphenols , free amino acids with Tie-guanyin machining process change regularly . Chaoqing is the critical manufacturing process ,high temperature causes degeneration of enzyme inactivation and stops fermentation , Tie-guanyin containing material is cured in Chaoqing process . Thereafter in the Rounian , Honggan and other processes ,the content of caffeine ,tea polyphenols is stabilized ,the content of free amino acids reduces slowly .
