| Summary: | Volatile oils of ginger (Zingiber officinale) and galanga (Languas galanga) were extracted from fresh and dried rhizomes using normal and vacuum steam distillation. Distillates were continuously extracted with dichloromcthane.
Flavour compounds of the extracted volatile oil of ginger and galanga have been identified using gas chromatography, Kovats retention indices, odour evaluation and gas chromatography-mass spectrometry analysis. Thirteen aroma components were identified in ginger oil and fifteen components in galanga oil.
Abstrak:
Minyak meruap yang terdapat dalam halia dan lengkuas diekstrak daripada rizom segar dan serbuk kering dengan menggunakan kaedah pcnyulingan stim pada tekanan normal dan tekanan rendah (vakum). Distilatnya pula diekstrak dengan diklorometana.
Sebatian perisa yang terdapat di dalam minyak meruap halia (Zingiber officinale) dan lengkuas (Languas galanga) telah dikenal pasti melalui analisis kromatografi gas (KG), penentuan indeks Kovats, penilaian bau dan kromatografi gas-spektrometri jisim (KG-SJ). Sebanyak 13 sebatian aroma telah dikenal pasti dalam minyak halia sementara 15 sebatian aroma dalam minyak lengkuas.
