Method for drying extraction of jasmine hydrolat from jasmine flowers

Abstract

The invention discloses a method for drying extraction of jasmine hydrolat from jasmine flowers. The method comprises the following steps: cleaning jasmine petals, removing impurities, sterilizing thejasmine petals in a far infrared sterilizer for 10-30s and then at a high temperature of 120-130 DEG C at pressure of 0.2-0.3MPa for 30-40min, soaking the jasmine petals in water for 1-24h to allow awater content of the jasmine petals to be 30-50%, and grinding the vacuum-dried jasmine petals in an ultramicro wall breaking grinder to above 400 meshes.

Description

technical field [0001] The invention belongs to the technical field of health products, and mainly relates to a method for extracting jasmine hydrosol by drying jasmine flowers. Background technique [0002] Jasmine, also known as jasmine, is the collective name for the evergreen shrubs or vines of the genus Jasminum in the family Jasminum. Jasmine is native to the Jiangnan region and the western region of China; India and Arabia, the central production area is near the Persian Gulf, and it is now widespread.

Problems solved by technology

[0005] In the early years, products such as lavender hydrosol and rose hydrosol appeared on the market, but there is no such thing as jasmine hydrosol, because the cost of distilling jasmine hydrosol is too high, and few manufacturers use distillation. method to extract jasmine pure dew; and the use of leaching method or supercritical CO2 extraction method to extract jasmine pure dew will not produce by-products - jasmine pure dew

There is a lot of research on jasmine hydrosol, but very little research on jasmine hydrosol as a product

The retrieved documents, such as the application number 201510868175.9, and the Chinese patent titled "A Method for Extracting Jasmine Hydrosol and Top Note", disclose a method for extracting Jasmine Hydrosol and Top Note, which includes distillation, condensation , oil-water separation, adsorption, primary distillation concentration, alcohol analysis, secondary distillation concentration and other steps; in the process step oil-water separation of the method, jasmine pure dew and pure dew can be separated; but the method is to extract jasmine pure dew The main purpose is to produce jasmine pure dew. It is not a process method with the main purpose of producing jasmine pure dew. The amount of pure dew obtained is small and it is only an incidental product.
