Abstract

The invention relates to a microwave assisted extraction method of lemon essential oil. The extraction method comprises the following steps: (1) cleanly cleaning lemon peel, then, drying and crushing, so as to obtain lemon peel powder; (2) putting the lemon peel powder into a nonmetallic vessel, adding water and salt into the nonmetallic vessel, putting the nonmetallic vessel into a microwave extraction device, and then, heating materials in the nonmetallic vessel until the materials in the nonmetallic vessel are boiled; applying microwave radiation to the materials in the nonmetallic vessel after the materials in the nonmetallic vessel are boiled, and collecting generated vapor and condensing, so as to obtain crude lemon essential oil, wherein the manner of microwave radiation applying is intermittent; (3) separating water and impurities from the crude lemon essential oil, thereby obtaining the lemon essential oil. The extraction method disclosed by the invention has the advantages of environmental friendliness, rapidness, energy saving and the like, and is less in environmental pollution, easy in raw material obtaining, simple in process, convenient in operation, low in energy consumption, low in cost and high in efficiency; the prepared lemon essential oil is free from organic solvent residues and is high in quality and high in purity, and the natural quality of the lemon essential oil is kept.

Description

technical field [0001] The invention relates to a method for extracting lemon essential oil from lemon peel, in particular to a microwave-assisted extraction method for lemon essential oil. Background technique [0002] The biologically active ingredients extracted from plants are natural and environmentally friendly, and have no or little side effects for long-term use. They have been successfully used in skin care, whitening, anti-aging and other cosmetic fields. Compared with traditional cosmetics, plant-derived active ingredients are more easily absorbed and digested by the skin, with obvious curative effects, strong pertinence, and no deposition in the body. The research and development of cosmetics using active ingredients in plant extracts is a hot spot and trend in the cosmetics industry at present, and will also become the leading force in the cosmetics industry in the future. [0003] China is rich in plant resources, and the plant extract industry is developing f...
