Industrialized joint extraction technology of cinnamon polyphenol extract and cinnamon essential oil

Abstract

The invention discloses a cinnamon polyphenol extract and cinnamon essential oil industrialized joint extraction technology. The technology includes the specific steps that cinnamon raw materials are cleaned and subjected to impurity removal, the cinnamon raw materials are fed into an extractor, a waterborne solvent is added, extraction is carried out under the micro-negative pressure condition, an extracting solution is obtained, the extractor is extracted to be in micro-negative pressure, generated water vapor and part of cinnamon volatile components are jointly extracted out and then enter a condenser to be condensed, and condensate is obtained; the condensate passes through an oil-water separator so that cinnamon essential oil and water vapor can be separated, non-condensable tail gas is emptied, the extracting solution is filtered and then concentrated, the pH value is adjusted to be neutral, the concentrated solution is dried, and cinnamon polyphenol extract is obtained; cinnamon dregs are subjected to subcritical fluid extraction, extract is obtained, and cinnamon essential oil is obtained after analysis. Industrialized production application of joint extraction and separation of the cinnamon essential oil and the cinnamon polyphenol extract in cinnamon is achieved.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicine processing, and in particular relates to an industrial combined extraction technology of cinnamon polyphenol extract and cinnamon essential oil. Background technique [0002] Cinnamon, also known as Yugui, Mugui, Yushu, Dagui, Spicy Gui, Pinganshu, and Chinese Cassia, is the dry bark of the Lauraceae plant Cinnamon. Sliced ​​or powdered, used raw. Sweet and slightly astringent, slightly pungent with refreshing fragrance, it is a kind of medicinal and edible plant resource. Cinnamon is rich in active ingredients, and one of the active ingredients, cinnamon polyphenols, has various pharmacological effects such as lowering blood sugar, regulating blood lipids, anti-tumor, and anti-oxidation, and can reduce the risk of metabolic syndrome, diabetes, and cardiovascular diseases. Another main active ingredient of cinnamon is volatile oil, and the content of volatile oil in cinnamon...

Problems solved by technology

[0003] my country is quite rich in cinnamon resources and is the largest producer and exporter in the world. However, the comprehensive utilization of cinnamon resources is still insufficient, and it is still limited to the export of crude cinnamon essential oil and raw materials of cinnamon bark.

There are also some studies on cinnamon polyphenol extracts or cinnamon oil, but the processes used are relatively complicated, including supercritical CO2 extraction, resin purification and other processes, the initial investment or operating costs are high, and the product is single, resulting in serious resources. waste

[0004] As mentioned above, there are still deficiencies in the deep processing of cinnamon in the background technology. For example, the patent CN201110197202 (a cinnamon polyphenol extract, its preparation method and its use) removes grease by supercritical carbon dioxide, extracts it with an aqueous solvent, and then extracts the crude oil. The extract is purified by resin to obtain cinnamon polyphenol extract, but there are problems such as low product yield, complex impurity components, and unstable product color when using this process. In addition, it causes the loss of cinnamon essential oil, which virtually reduces the deep processing value of cinnamon.
