Problems solved by technology

[0005] Various organic solvents can be used for solvent extraction, such as: propane, butane, ethanol, isopropanol, ethyl acetate and other solvents. The extraction method is used to prepare capsicum oleoresin through repeated collection and repeated concentration, so that the yield and color value can be improved, but the process is cumbersome, and the process pipeline and solvent tank occupy a large space and transportation site, and more solvents need to be stored. with added solvent recovery system

Embodiment Construction

[0028] A kind of supercritical CO of the present invention 2 The technical process for extracting chili oleoresin, the technical process steps are: remove the stalk of dried chili, separate the seed meat, take 100kg of chili raw material and crush it into 30-40 mesh, put the crushed material into the material basket, and then put the material basket into Put it into the high-pressure extraction kettle, close the kettle cover and safety device, adjust and confirm the cycle pressure in the computer configuration to 40MPa, the temperature to 50℃, the flow parameter to 600kg / h, and feed CO 2 Into the extraction kettle, fill to the required extraction pressure above 40MPa, dissolve the solute, maintain the temperature of the system medium, and automatically start the regulating valve after reaching the system circulation pressure of 40MPa, and release the extract to the separation kettle through throttling expansion. The temperature in the process does not exceed 50°C before the co...

Abstract

A process for capsicum oleoresin extraction by supercritical CO2 includes: crushing dried chili; loading the chili into a high-pressure CO2 extraction kettle; setting the system circulating pressure to be 25-40 MPa, the temperature to be 50 DEG C and the flow to be 600 kg / h; feeding CO2 to the extraction kettle; starting an automatic regulating valve when the pressure is up to 40 MPa; releasing extracts to separation kettles through a throttle expansion valve; setting a first-grade separation pressure of 10MPa and the temperature without exceeding 45-50 DEG C, and a second-grade separation pressure of 4-10MPa and the temperature without exceeding 45 DEG C to run for half an hour; collecting the capsicum oleoresin from a first separation kettle; and collecting capsicol from a second separation kettle. The process is simple, healthful, environmental-friendly, and pollution-free, and is suitable for large-scale mass production. The extracts are high in purity, high in yield and stable in quality, and have no organic solvent residues.

Description

technical field [0001] The present invention relates to extraction technology by physical method, especially to a kind of supercritical CO 2 Capsicum oleoresin extraction and its process method. Background technique [0002] Domestically, the extraction and production methods of capsicum oleoresin, an important raw material for extracting and separating capsanthin and capsaicin, are mainly carried out by oil-soluble method and organic solvent immersion method. [0003] The process is: according to the pretreatment of peppers, that is: removal of pepper stalks, separation of skin and seeds, grinding and granulation of pepper skin and flesh, transporting them to a solvent tank and soaking them in organic solvents, and collecting them after a certain period of time or several hours The leaching solution is concentrated and extracted to form a viscous oleoresin containing capsaicin and capsaicin, which provides raw materials for the separation of red pigment and capsaicin.
