Problems solved by technology

[0005] The traditional mechanical pulverization and solvent impregnation method has simple process and convenient operation, but there are disadvantages such as low extraction yield, low purity of extracted product, poor quality, odor and solvent residue, etc., so the application is limited
Microbial and enzyme fermentation methods require a high level of technology, and the process is complicated, and is still in the laboratory stage

Embodiment Construction

[0018] The supercritical carbon dioxide continuous flow extraction and separation system includes: extractor, separator, carbon dioxide booster system, carrier pump, electronic control system, pressure regulating system and filter, etc. Except for the electronic control system, valves and pipes are used between them. connect. The extractor and the primary separator have heating facilities, and the secondary separator has heating and cooling facilities to control the extraction or separation temperature. There are two types of carbon dioxide pressurization systems: one is the direct compression type pressurized by a compressor; the other is a liquefaction pressurized gasification type composed of a refrigeration liquefier, a high pressure carbon dioxide pump and a gasification premixer.

[0019] 1, the present invention is described in detail by taking an extractor secondary separator as an example for loading 0.5 kg of dry tomato powder at a time.

[0020] 1) Weigh 0.5 kg of ...

Abstract

The process of extracting and separating lycopene from tomato includes the steps of: preparing tomato dry powder; filling tomato dry powder to ensure the flow and homogeneous distribution of supercritical CO2; starting extracting and separating device and regulating the flow rate of CO2 and entrainer and pressure in the two stage separator; extracting and separating lycopene continuously at flowing supercritical CO2 condition; and discharging product. The present invention has high extracting and separating speed, high extracting efficiency, high purity of separated product, low running cost and no pollution.

Description

[0001] 1. The field [0002] The invention belongs to the technical field of supercritical fluid extraction and separation, in particular to a method for extracting and separating lycopene from tomatoes by using supercritical carbon dioxide. 2. Background technology [0003] Lycopene is a kind of carotenoid, widely present in tomatoes, watermelons, papayas, grapes, plums and guava. It was first extracted and isolated from tomatoes, so it is called lycopene. Lycopene has special effects such as anti-oxidation, anti-cancer and anti-cancer, prevention and treatment of cardiovascular diseases, etc., and has attracted much attention from the pharmaceutical industry and the health care product manufacturing industry, and has a broad application background. [0004] The methods for extracting and separating lycopene from tomatoes mainly include: 1) direct mechanical pulverization method, which is to make colored powder by drying and mechanically pulverizing the tomato skin; 2) solven...
