Abstract

In order to investigate some chemical components, higher alcohols, ethyl acetate and volatile compounds of Vitis vinifera red wines were analyzed by HPLC, GC and GC-MS. During the process of ripening for the content of wine and acids were much changed, particurally the content of tartaric acid was decreased largely. Content of total phenolics and phenol flavonoid in wines which manufactured with Malbec varieties as 470mg/L and 245mg/L respectively, was higher than those in Cabernet sauvignon (310mg/L, 135mg/L) and Cabernet franc (425mg/L, 125mg/L) wines, and nonflavonoid was higher in Cabernet franc wine(300mg/L) than in others. Content of acetaldehyde was higher in Malbec wine (33mg/L) than in Cabernet sauvignon (26mg/L) and Cabernet franc (28mg/L) wines. Amount of methyl alcohol, propanol and isoamyl alcohol were higher in Cabernet sauvignon wine than in others, and isobutanol was more in Malbec wine(64mg/L), ethyl acetate was more in Cabernet franc wine as 35mg/L than in Malbec(28mg/L) and in Cabernet sauvignon (23mg/L) wines. Volatile compounds were isolated about 87~91 varieties from concentrates of three red wines by GC, and thirty-five compounds including terpine-4-ol were identified by GC-MS.

Vitis vinifera 적포도주의 화학성분, 고급 알콜, esters 및 휘발성분 등을 측정하기 위하여 HPLC, GC및 GC-MS등의 기기를 이용하였다. 포도주의 저장 숙성중에는 산류의 변화가 많았는데, 특히 tartaric acid가 현저히 감소하였다. Total phenolics와 phenol flavonoid의 함량은 Malbec 품종으로 제조한 포도주가 각각 470mg/L과 245mg/L로서 Cabernet sauvignon (310mg/L, 135mg/L)과 Cabernet franc (425mg/L, 125mg/L) 포도주보다 많았고, nonfalvonoid의 함량은 Cabernet franc 포도주가 300mg/L로서 Malbec (225mg/L)과 Cabernet sauvignon (175mg/L) 포도주보다 많았다. Acetaldehyde 함량은 Cabernet sauvignon (26mg/L)과 Cabernet franc (28mg/L에 비하여 Malter(33mg/L) 포도주에서 많았다. Methyl alcohol, propanol 및 isoamyl alcohol은 다른 두 포도주에 비하여 Cabernet sauvignon 포도주에서 많았고, isobutanol은 Malbec 포도주가 64mg/L이었으며, ethylacetate는 Cabernet franc 포도주가 35mg/L로서 Malbec (28mg/L)과 Cabernet sauvignon (23mg/L) 보다 많았다. 세품종(Cabernet sauvignon, Cabernet franc, 및 Malbec)의 포도주 농축물로부터 GC를 이용하여 87~91여종의 휘발성분을 분리하였고, 그 중 terpine-4-ol을 비롯한 35종을 GC-MS를 사용하여 동정하였다.
