Abstract

The invention discloses production technology for extracting purified lycopene from tomato waste residue serving as a raw material, which comprises the following steps of: firstly, separating tomato skin from tomato seeds; secondly, extracting lycopene extract from the tomato skin by subcritical extraction technology; and finally, separating and purifying the lycopene in the lycopene extract by using a silica gel short column. The extraction ratio of the lycopene is 80 to 90 percent, and the lycopene content of extracted lycopene oleoresin can reach 6 to 50 percent.

Description

technical field [0001] The invention relates to a production technology for extracting and purifying lycopene from tomato waste residue, which belongs to the production and preparation industries of food, health products and medicines. Background technique [0002] Lycopene is a non-cyclic planar conjugated polyunsaturated aliphatic hydrocarbon carotenoid compound composed of 11 conjugated and 2 non-conjugated carbon-carbon double bonds, which has a variety of important physiological activities , such as quenching singlet oxygen and scavenging free radicals; preventing the occurrence of coronary heart disease; anti-cancer and activating immune cells, etc. In recent years, lycopene has been widely used in health food, medicine and cosmetic industries as a food additive with dual functions of natural food coloring, nutrient and nutritional coloring, and has become a research hotspot in nutrition, medicine, food science and other disciplines at home and abroad. Lycopene is mai...
