Process for extracting prolycopene oil resin with supercritical fluid

Abstract

A process for extracting lycopene oil resin from tomato or water melon by supercritical fluid (CO2, propane, ethane, or ethene) includes pre-treating for removing sugar, gum and water from raw material, extracting with said supercritical fluid to obtain lycopene oil resin, packing it under protection of inertial gas in dark position or vacuum packing, and low-temp storage. Its advantages are simple process, high efficiency, low energy consumption, no pollution and low cost.

Description

technical field [0001] The invention relates to a method for extracting lycopene oleoresin by using tomato, watermelon and the like as raw materials, especially a method for extracting lycopene oleoresin by using supercritical carbon dioxide, propane, ethane and ethylene fluid. Background technique [0002] The countries that produce lycopene oleoresin on a large scale in the world today mainly include Israel, the United States, Germany, Japan and other countries, and the method used is solvent extraction [WO97 / 48287, WO96 / 13178 (CN1176577A)]. The disadvantages of the solvent extraction method are the consumption of a large amount of valuable organic solvents, high energy consumption, large loss of lycopene during the extraction process, solvent residues, and low extraction rate (only about 80%). Contents of the invention [0003] In order to solve the shortcomings of the above-mentioned existing solvent extraction method for extracting lycopene, the present invention prov...
