Problems solved by technology

At present, steam distillation is the main method for extracting toi dai flower essential oil, but steam distillation will cause thermal decomposition and hydrolysis of the thermally unstable or easily oxidized components in the essential oil under high temperature conditions, resulting in a cooking smell, resulting in low quality of essential oil ; At the same time, the extraction process requires a large amount of water, which takes a long time and consumes a lot of energy
In addition, the use of a single extraction process will lead to a low extraction rate of essential oils, and at the same time it is difficult to retain all the aromatic components in the flowers, and some components are left in the toi dai flower hydrosol

Abstract

The invention discloses a method for extracting the essential oil of toi toi flower. The method comprises (1) performing solvent-free microwave extraction on fresh toi toi flower after pretreatment to obtain a microwave extract; (2) extracting the microwave extract in 3 Stand at ℃~8℃ for stratification, the oil layer is the essential oil of Toi Toi flower, and the water layer is the pure dew from Toi Toi flower; The points are the recovered essential oil of Toi Toi flower pure dew; (4) The first extracted essential oil of Toi Toi flower and the recovered essential oil of Toi Toi flower pure dew are reconciled in proportion to obtain the toi toi flower essential oil. The invention adopts solvent-free microwave extraction technology, which effectively avoids the influence of organic solvents on the fragrance and quality of essential oils, and has high extraction rate and high purity of essential oils, simple process and low extraction cost; the aroma in the pure dew of daidaihua is recovered by molecular distillation technology. The ingredients are green and environmentally friendly, reducing the waste of resources; the blended essential oil is close to the aroma of natural flowers, with a fragrant smell and no miscellaneous smell.

Description

technical field [0001] The invention belongs to the field of plant essential oil extraction, and in particular relates to a method for extracting toi dai flower essential oil. Background technique [0002] Daidaihua is the flower bud of the Rutaceae plant Daidai, also known as Citrus aurantii, sour orange, etc. It is mainly distributed in the south of the Yangtze River in my country. It is one of the homologous varieties of medicine and food announced by the National Health and Family Planning Commission. Toi Daihua is rich in volatile oil and has an elegant aroma. It has the effects of digestion, soothing the liver, resolving phlegm, harmonizing the stomach, and regulating qi. It is widely used in food and daily necessities, and it is also the top spice in cosmetics. [0003] Toi Toi flowering period is short, the flowers are delicate, and the fragrance is easily lost. At present, steam distillation is the main method for extracting toi dai flower essential oil, but steam ...
