  • 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.

  • A total of 49 phenolic compounds were identified from the aged red wines made from Cabernet Gernischt (Vitis vinifera L. cv.) grapes, a Chinese characteristic variety, including 13 anthocyanins, 4 pryanocyanins, 4 flavan-3-ol monomers, 6 flavan-3-ol polymers, 7 flavonols, 6 hydroxybenzoic acids, 5 hydroxycinnamic acids, 3 stilbenes, and 1 polymeric pigment. Evolution of these compounds was investigated in wines aged 1 to 13 months. Variance analysis showed that the levels of most phenolics existed significant difference in between wines aged 3 and 9 months. Cluster analysis indicated that 2 groups could be distinguished, one corresponding to wines aged 1 to 3 months and the other to wines aged 4 to 13 months. It was thus suggested that there were 2 key-stages for the development of fine wine quality, at the aged 3 and 9 months, respectively. This work would provide some helpful information for quality control in wine production.
