Abstract

The present invention relates to a method which utilizes fresh aromatic plants as materials and combines the microwave heating technology with the vacuum technology to prepare essential oil. The method includes the following steps: the tissue structure of aromatic plant material is broken by cutting and grinding; after microwave irradiation is utilized to heat the aromatic plant material to a certain temperature, pressure is rapidly reduced to intensely gasify the moisture in the material so that the histiocytes, oil vacuoles and gland cells of the aromatic plants are broken; an aromatic substance is released from the cells and quickly volatilize; and the effect of the intense gasification and spreading of the moisture in the fresh material can effectively promote and intensify the volatilization of the aromatic ingredient, so that the abstraction of the essential aromatic plant oil can be fulfilled in a short time. The processing temperature in the process of the abstraction of the essential plant oil is low, the oxidation of sensitive ingredients can be avoided, the stability of the ingredients of the essential aromatic plant oil can be kept to the max, the time of abstraction is short, the efficiency is high, energy can be saved, and industrialized production can be conveniently realized.

Description

technical field [0001] The invention relates to an essential oil preparation method using fresh aromatic plants as raw materials, in particular, the aromatic plant essential oil is prepared by microwave heating and vacuum technology. Background technique [0002] Aromatic plants are a group of plants that have common properties of both medicinal plants and spice plants. The aroma components contained in it are an important part of natural flavors and fragrances, which can be extracted as essential oils and used in various industries such as medicine, food processing, and cosmetics. Natural flavors have a unique fragrance that cannot be replaced by synthetic flavors, as well as natural and safe characteristics, which make the production of natural flavors continue to sell well. At present, in Europe, America, Japan and other developed countries, natural flavors are replacing synthetic flavors in various fields with an unstoppable trend. Modern scientific research has also f...
