Problems solved by technology

However, due to the operation at a higher temperature for a long time, it is easy to cause thermal decomposition or hydrolysis of the heat-sensitive compounds and easily hydrolyzed components in the essential oil, resulting in the loss of the active components of the essential oil, resulting in a low extraction rate.
Supercritical CO2 extraction and subcritical extraction are carried out at higher temperature and pressure, which will also damage the essential oil components and affect the extraction rate

Abstract

The invention relates to a processing method of lavender essential oil. Fresh lavender is enzymatically hydrolyzed with lysozyme, then inactivated, extracted with liquid carbon dioxide after inactivating the enzyme, and separated to obtain lavender essential oil. The invention has low extraction temperature and low pressure, which can effectively prevent damage to the essential oil by higher temperature and pressure, and improve the extraction rate; the invention adds a retaining agent, which can obviously prolong the service life of the essential oil.

Description

technical field [0001] The invention relates to a processing method of lavender essential oil. Background technique [0002] Lavender, also known as Lavender, is a perennial plant of the genus Lavender of the Labiatae family. It is native to the Mediterranean region and has been transplanted all over the world. Since 1952, my country began to introduce varieties from France, and in 1960, it was planted on a large scale in Xinjiang, Jiangsu and other places. Lavender essential oil is the oily liquid extracted from the flower spikes of Lavandula angustifolia plants. It contains a variety of aromatic compounds, with a tangy fragrance and strong fragrance. It is an important natural fragrance. It also has various physiological functions such as insect repellent, odor removal, sterilization, calming, hypnosis, and mental stress relief. Food additives and other fields. [0003] Commonly used essential oil extraction methods include steam distillation, pressing, organic solvent ...
