Abstract

The invention relates to an essential oil extraction method, and particularly discloses a separation and purification method of garlic essential oil. The method comprises the steps of garlic cleaning and pulping, enzymolysis, ultrasonic extraction, extraction, centrifugation and distillation and purification. By conducting enzymolysis and extracting effective components in filter residues through an extracting agent, the extraction rate of the garlic essential oil and the effective components of the final garlic essential oil are increased. The separation and purification method of the garlic essential oil is mild in operating condition, low in cost and suitable for industrial production.

Description

technical field [0001] The invention relates to a method for extracting essential oil, in particular to a method for separating and purifying garlic essential oil. 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 biologically active ingredient of garlic is garlic essential oil (beneficial allicin), which only accounts for about 0.2% of garlic ingredients. Garlic essential oil contains more than 140 kinds of extremely precious natural substances, and its components can be divided into two categories: one is volatile components (also known as garlic oil), including more than 40 kinds of sulfide compounds; the other is non-volatile components, I...
