Description
Technical field
The present invention relates to a kind of low temperature pressing method of eucommia ulmoides seed oil, relate in particular to and a kind ofly produce eucommia ulmoides seed oil with the cold press method, and use the ultra-filtration membrane purification technique to improve the method for Eucommia Oil a-linolenic acid content.
Background technology
The bark of eucommia (Eucommia ulmoides Oliver) is the distinctive famous and precious tonic Chinese medicine material of China, modern age, pharmacological experiment studies show that, the effects such as the bark of eucommia has strengthening the bones and muscles, invigorating the liver and kidney, hypotensive, anti-inflammatory is antibacterial, anticancer, strengthening immunity, these pharmacologically actives are the object for studying based on Cortex Eucommiae and Folium Eucommiae mainly, and also less to the relevant research such as eucommia ulmoides seed oil extraction, purifying and exploitation.Because the total fatty acid content of eucommia ulmoides seed oil reaches more than 80%, the a-linolenic acid content up to more than 60%, is a kind of senior edible oil with nourishing function.Along with growth in the living standard, hypertension, hyperglycemia, people with hyperlipidemia quantity constantly increase, the mankind increase day by day to demand hypotensive, the reducing blood-fat series products, therefore, a kind of safety non-toxic is provided, and the Eucommia Oil production method that the a-linolenic acid content is high has good Social benefit and economic benefit, and can make the eucommia resource advantage of China's abundant be converted into industrial advantage.
The extracting process of eucommia ulmoides seed oil mainly contains milling process and solvent extraction method at present.Milling process is applicable to suitability for industrialized production, but oil plant will be first through the high temperature frying or cook, effective constituent in Eucommia Oil is heated is destroyed, and oil yield rate is lower; The needed leaching of solvent extraction method, extraction time are longer, and the crude oil of extraction also needs further processing, complex manufacturing.Purification process such as urea adduct method commonly used, the complexation chromatography method, lipase method of enrichment etc. relates to the use of reagent, can cause the residual of solvent, and the production time is longer; CO
2Supercritical extraction, the molecular distillation method, though the crystallizing process under low temperature etc. are put the pollution of having avoided solvent, the equipment used production cost is higher.Present method adopts the cold press technology, need to be by any chemical substance, and oil yield rate is higher, does not have the dissolvent residual problem, and has adopted simultaneously the concentrated and purified a-linolenic acid of nanofiltration.
