Problems solved by technology

Compared with the method of first extracting lycopene and then saponifying, this patent has: 1), the amount of alkali used is large, resulting in waste of resources; 2), large saponification equipment is required, the processing capacity is limited, and the production capacity is low; 3), Saponification does not work well due to plant cell walls
In addition, this patent has many steps and is cumbersome, which is not conducive to large-scale industrial production;

Abstract

The invention discloses an industrialization method for improving purity of lycopene oil resin. The method comprises process steps of (1) adding an alcohol solvent in the lycopene oil resin for evenly stirring to obtain mixed liquor; (2) adding an alkaline aqueous solution in the mixed liquor to stir, and neutralizing a fatty acid compound in the oil resin to obtain neutralization liquor; (3) adding an alkaline aqueous solution in the neutralization liquor to stir, and saponifying an oil compound in the neutralization liquor to obtain saponification liquor; and (4) adding an alcohol-water solution in the saponification liquor to stir, then adding 6# solvent naphtha, stewing and laying after evenly stirring, collecting a 6# solvent layer, concentrating and obtaining the lycopene oil resin with improved purity. The method firstly neutralizes long-chain fatty acid in the lycopene oil resin, then saponifies the oil, can effectively reduce intensity of saponification, reduces packing of produced saponin on lycopene and obviously improves yiels. The method is simple in process and strong in maneuverability, the yield of the lycopene is higher than 90%, and obtained products are stable in state.

Description

technical field [0001] The invention relates to a method for purifying plant extracts, in particular to an industrial method for improving the purity of lycopene oleoresin. Background technique [0002] Lycopene is widely distributed in nature, and its content is higher in mature red plants, such as tomato, watermelon, carrot, grape, red grapefruit, strawberry, citrus, etc. Its molecular formula is C 40 h 56 The molecular weight is 536.85. It is a kind of total carotenoid. Among all carotenoids, it has a strong function of eliminating singlet oxygen and free radicals. Its singlet oxygen elimination function is twice that of carotene. 100 times that of vitamin E, lycopene is more powerful than β-carotene in eliminating free radicals, the "source of all diseases" in the human body. In 2003, the American "Time" magazine listed lycopene at the top of the "food that contributes the most to human health", and lycopene is also called "gold in plants". At present, lycopene has b...
