Preparation
Garlic oil is typically prepared using steam distillation, where crushed garlic is steamed with the resultant condensation containing the oil. Garlic oil contains volatile sulfur compounds such as diallyl disulfide, a 60% constituent of the oil. Steam-distilled garlic oil typically has a pungent and disagreeable odor and a brownish-yellow color. Its odor has been attributed to the presence of diallyl disulfide. To produce around 1 gram of pure steam-distilled garlic oil, around 500 grams of garlic is required. Undiluted garlic oil has 900 times the strength of fresh garlic, and 200 times the strength of dehydrated garlic.Ether
