Abstract
A rapid gas chromatographic (GC) profiling method was applied to dairy products (milk and cheeses) for the simultaneous analysis of volatile and nonvolatile organic acids. Cheese samples were first made into aqueous samples by dissolving in water. The aqueous samples were then extracted with organic solvents after the acidification and NaCI saturation. The organic layers (diethyl ether : hexane= 1 : 1) were extracted with
고체상 추출법을 이용하여 우유와 cheese에 존재하는 유기산들을 분리 농축한 후 test-butyldimethylsilyl (TBDMS) 유도체화하여 GC와 GC-MS로 분석하였다. 치이즈에 존재하는 유기산들을 고체상추출하기 위해서는 먼저 치이즈를 중류수에 용해시킨 후 산성화시켜 용매 추출함으로써 염을 제거할 수 있었으며 이어
