Problems solved by technology

[0002] At present, the chrysanthemum extracts on the market are mainly extracted with ethanol or water, and then concentrated at high temperature. Due to long-term high-temperature concentration, its original aroma and fragrance are destroyed, especially the top fragrance, which affects its quality.
Although this type of product can retain some functional components in chrysanthemum, the complex components directly affect the stability of the extract, and problems such as precipitation and discoloration are prone to occur during storage
[0003] Pervaporation membrane separation technology is an emerging membrane separation technology. This technology mainly uses the selectivity of the membrane to preferentially select the target components and concentrate them on the permeate side. It can achieve the purpose of separation and concentration at the same time. The fermentation and separation process of bioethanol and butanol, the dehydration of organic matter and the separation process of organic matter in wastewater have been widely studied, but the application research in plant extracts is still less

Abstract

The invention discloses an extraction method of a natural chrysanthemum effective aroma component, comprising the following steps: mixing dried chrysanthemum and saline solution according to the mass ratio of 1: 10-50; extracting at 10-20 DEG C for 0.5-2h, filtering to remove solids so as to obtain a water extract of chrysanthemum, carrying out pervaporation separation on the water extract of chrysanthemum as a feed liquid under the condition of 10-20 DEG C by the utilization of a hydrophobic organic membrane for 0.5-1 h, and collecting a penetrating fluid, namely the natural chrysanthemum effective aroma component. The natural chrysanthemum aroma obtained by the method is real, has good stability and has a wide application range.
