Embodiment 2

[0017] The implementation method is as follows: select fresh ginger as raw material, remove surface silt and other impurities, then wash it with clear water, put the washed ginger into an oven, and dry it to a water content of 12% at a temperature of 55°C, and dry the dried ginger to a water content of 12%. Ginger is put into pulverizer and is pulverized into 65 purpose ginger powder; Take ginger powder 100kg and put it into the material barrel of extraction kettle, inject carbon dioxide gas into extraction kettle, keep the temperature and pressure of carbon dioxide gas in the extraction kettle at its supercritical state and Natural raw material contact; the extraction temperature is 50°C, the pressure is 23MPa; the flow rate of carbon dioxide gas through the extraction kettle is 1.1t / h, and the extraction time is 3h, so that the ginger oil in the ginger powder is fully dissolved in the supercritical fluid, from The outlet of the separation kettle collects the fluid containing ...

Abstract

The invention discloses a supercritical extracting method of ginger oil. The ginger oil is extracted from ginger by adopting supercritical carbon dioxide fluid. Before extracting, ginger is selected,washed, dried and pulverized, the extracting temperature is 25-65 DEG C, and the pressure is 15-28 MPa; the flow of carbon dioxide gas passing through an extracting kettle is 1.0-1.3 t/h, and the extracting time is 2-4 h. The carbon dioxide fluid under the supercritical state is used as an extracting solvent, the solvent is recycled in the same system, the solvent consumption is small, the price is cheap, and thus the extracting cost is low. The carbon dioxide fluid is green pollution-free solvent, the extracted ginger oil has the advantages of being high in quality and purity, good in color,free of peculiar smell, solvent residue and environmental pollution and the like, the extracting cycle is short, residues after the ginger oil is extracted also contain effective components like starch and dietary fiber, and the ginger can be comprehensively utilized. The technology is simple, and the energy consumption is low.

Description

technical field [0001] The invention belongs to the technical field of natural product extraction, and in particular relates to a supercritical extraction method of ginger oil. Background technique [0002] Ginger oil is light yellow to yellow transparent liquid, the main components are gingerone, gingerol, zingiberene, aromatic curcumene, farnesene, limonene, eucalyptol, β-phellandrene, borneol, linale Alcohol, methylheptenone, nonanal, decanal, bornyl acetate, geraniol, and spicy gingerin, etc., can be used to prepare food flavors, and can also be used in small amounts in some cosmetics and soap flavors. [0003] At present, steam distillation, pressing, and organic solvent extraction are mostly used to prepare ginger oil, but these methods not only have low extraction rate, high cost, pollution, but also easily damage the active ingredients. Contents of the invention [0004] The object of the present invention is to provide a supercritical extraction method of ginger ...
