Problems solved by technology

[0002] At present, the plant perfumes on the market are mainly extracted with ethanol or water, and then concentrated at high temperature. Due to long-term high-temperature concentration, the original aroma and fragrance are destroyed, especially the top fragrance, which affects its quality.
Although this type of product can retain some functional components of plants, 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

Embodiment 1

[0017] Add 5% salt in distilled water to make salt water, take 50g of dried sweet-scented osmanthus, add 500g of salt water, extract at 5°C for 8 hours, filter to remove solids to obtain sweet-scented osmanthus low-temperature extract; take sweet-scented osmanthus low-temperature extract as feed liquid At 5°C, the PDMS / PVDF composite pervaporation membrane filled with hydrophobic nano-calcium carbonate was used for pervaporation separation for 2 hours, and the collected permeate was natural sweet-scented osmanthus perfume.

Embodiment 2

[0019] Add 15% salt in distilled water to make salt water, take 50g of roses that have been dried and crushed to 50 mesh, add 5000g of salt water to extract at 20°C for 1 hour, filter and remove solids to obtain low-temperature extract of roses; take low-temperature roses The extract was used as a feed solution at 20°C, and the polyurethane membrane filled with hydrophobic nano-calcium carbonate was used for pervaporation separation for 0.5h, and the collected permeate was natural rose water.

Abstract

The invention discloses a plant perfume low-temperature extraction technology. The technology mainly comprises the following steps: leaching and extracting the aroma component of a plant at a temperature of 5-20 DEG C, and concentrating to obtain the perfume. Since the extraction technology is carried out in a low-temperature condition, the energy consumption of the extraction process is low; and without cooking flavor, the obtained product realizes real restoration of the plant aroma and can be applied to food drinks and cosmetics.
