Changes in Volatile Sulfur Compounds of Garlic (Allium sativum L.) under Various Drying Temperatures

건조 온도에 따른 마늘의 휘발성 함황성분의 변화

The volatile sulfur compounds in raw and dried garlic (Allium sativum L.) under various temperatures (50, 60, 70 and $80^{\circ}C$ ) were separated, identified by GC and GC/MS. In hexane extracts of raw garlic, 8 volatile sulfur compounds were identified and 11 compounds were identified in steam distillation extracts. The volatile sulfur compounds of raw and dried garlic were mostly composed of diallyl disulfide, diallyl trisulfide, allyl methyl trisulfide. According to the increase of drying temperature total amounts of volatile sulfur compounds in the hexane extracts decreased to $40{\sim}75$$, and in the steam distillation extracts decreased to $10{\sim}20%$. The amounts of diallyl disulfide, allyl methyl trisulfide decreased more than other volatile sulfur compounds, but diallyl trisulfide comparatively decreased lower.

마늘외 휘발성 함황성분을 용매추출 및 수증기 증류법에 의하여 추출하여 GC와 GC/MS에 의하여 분리 통정하고 건조온도에 따른 이들의 함량 변화틀 조사하였다. 핵산 추출물에서 8종, 수중기증류물에서 11종의 향기성분을 동정하였으며 이들 중 diallyl disulfide와 diallyl trisulfide, allyl methyl trisulfide가 대부분을 차지하였다. 건조온도가 중가함에 따라 마늘외 휘발성 함황성분은 핵산 추출물에서 $40{\sim}75%$까지 감소하였고 수중기 증류물에서는 $10{\sim}20%$ 정도 감소하였다. 휘발성 함황화합물중 diallyl disulfide, allyl methyl trisulfide의 함량은 크게감소한 반면 diallyl trisulfide의 함량은 비교적 적게 감소하였다.
