Problems solved by technology

[0003] Plants mostly contain waxy components and other non-volatile fat-soluble components. They have certain physiological activities, but they contribute little to the aroma. They exist in essential oils and affect the appearance and fluidity of essential oils, affecting their use. In 1995, Italian Reverchon et al. published a study on the extraction of lavender essential oil and the separation of wax by using supercritical carbon dioxide, and prepared lavender essential oil by step-by-step analysis by cooling down to 0°C, which requires cooling the separator and increasing energy consumption. Although temperature-controlled rectification measures can solve the problem of essential oil wax removal, the operation process and equipment are complicated, and industrial production is not easy to control

Abstract

The lavender flower extracting process includes supercritical CO2 extraction of lavender oil from lavender flower, and secondary separation of fragrant lavender oil components from plant wax and other less volatile components. The process can obtain lavender oil product with high room temperature flowability, high volatility and fragrance the same as that of lavender flower, and wax component with high flower wax content and used as noble cosmetic material and lavender flower residue capable of being used as scented tea material. The process is simple, and easy to use in industrial production.

Description

technical field [0001] The invention relates to a method for extracting lavender flower aromatic essential oil and lavender flower wax and processing lavender flowers. Background technique [0002] The natural aromatic plant lavender is a perennial herb of the Lamiaceae family. It is native to the Mediterranean region and is currently mainly planted in Xinjiang in my country. The lavender aromatic components in the lavender flower spikes have antibacterial and calming effects. The traditional method of extracting lavender essential oil is obtained by steam distillation and oil-water separation. Due to the high temperature in the processing process, the linaloyl acetate with low stability will be hydrolyzed and the structure of other heat-sensitive substances will change, which will eventually lead to the aroma of lavender essential oil. Changes will affect its use value. Supercritical extraction technology is a new separation technology developed in recent years. Among them...
