Method for extracting and separating lycopene from tamato

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...
