Abstract

The invention discloses a method for extracting garlic essential oil by using isohexane with the assistance of ultrasonic waves. The method comprises the steps of crushing garlic, carrying out enzymolysis, carrying out ultrasonic extraction, carrying out steam distillation, carrying out extraction by using isohexane, carrying out dehydration treatment, and carrying out separation and evaporation to obtain garlic essential oil. The method has the advantages of low energy consumption and high oil yield, the isohexane is used as an extraction solvent and is safe and easy to recover, and the method is more suitable for industrial production.

Description

【Technical field】 [0001] The invention relates to a method for extracting essential oil, in particular to a method for extracting garlic essential oil with ultrasonic-assisted isohexane. 【Background technique】 [0002] Garlic is rich in nutrients and has high medicinal value. Modern research proves that garlic has the functions of anticoagulation, antitumor, lowering blood fat, lowering blood sugar, detoxification, anti-infection, anti-oxidation, anti-aging, protecting the liver, and protecting the cardiovascular system. also plays a very important role. [0003] The bioactive component of garlic is garlic essential oil (beneficial allicin), which only accounts for about 0.2% of garlic components. Garlic essential oil contains more than 140 kinds of extremely precious natural substances, and its components can be divided into two categories as a whole, one is volatile components (also known as garlic oil), including more than 40 kinds of sulfide compounds; the other is non...
