Problems solved by technology

This method has been widely used in many fields. For example, Chinese patent CN102850350A discloses a method for extracting evodiamine using a subcritical fluid. Reagent, under the state of temperature 30~80℃, pressure 1~10MPa, extract dynamically for 30~60min, then pass polar organic reagent into the extraction tank, under the state of temperature 80~120℃, pressure 0.3~3MPa, dynamically extract Extract for 30 to 80 minutes, cool the extract, pass through activated carbon and diatomite resin column, pass through the column liquid to concentrate and crystallize under reduced pressure, and then recrystallize the crystal with acetone solution to obtain evodiamine; in the extraction process of the present invention, extract and extract Liquid separation is more difficult, which will affect the final extraction rate

Abstract

The invention discloses a method for extracting green prickleyash oleoresin through subcritical dimethyl ether fluid. The method comprises the four steps of raw material pretreatment, extraction, exsolution separation and residue recovery. The green prickleyash oleoresin is extracted by adopting the subcritical dimethyl ether fluid, the equipment manufacture cost is low, the equipment input is less, the energy consumption is less, the whole production process is in the low-pressure vacuum closed environment, and the production safety is high; the extraction process is environment-friendly and pollution-free; the extraction temperature is relatively low and low temperature smashing is adopted, so that the character flavor substances and spicy element components of green prickleyash are relatively completely reserved, the net extraction rate of the green prickleyash oleoresin reaches 20-23%, the prickleyash spicy element content in the green prickleyash oleoresin is 120-130 mg / g, and the volatile oil content is 55-60 mL / 100g.

Description

technical field [0001] The invention belongs to the field of deep processing of green pepper oleoresin, and in particular relates to a method for extracting green pepper oleoresin with a subcritical dimethyl ether fluid. Background technique [0002] Green Zanthoxylum bungeanum can be used as a seasoning. It has the effect of increasing fragrance and removing fishy smell when cooking. In addition, it also has the functions of warming the middle and relieving pain, killing insects and relieving itching. treat. Extraction of green pepper oleoresin refers to using a suitable fluid or solvent to extract its aroma and numbness components from green pepper raw materials as much as possible, and then separate and recover the fluid or solvent to obtain a thick resinous product containing essential oils The main components of green pepper oleoresin are essential oils, pigments, resins, some non-volatile oils, amides and polysaccharides. Green Zanthoxylum oleoresin not only has a fu...
