Study on Extracting Allicin from Garlic by Microwave Irradiation

Allicin was extracted from garlic with alcohol as extractant by microwave irradiation.The extracted allicin was measured by spectrophotography.The effect factors such as microwave power,volume fraction of ethanol,the rate of garlic slurry to ethanol and microwave irradiation time on extraction of allicin from garlic were reviewed.The extraction process of allicin from garlic was that microwave power was 200 W,volume fraction of ethanol was 90 %,the rate of garlic slurry to ethanol was 1∶5(g/mL) and microwave irradiation time was 5 min.Under the condition extraction rate of allicin was 0.143 %.
