At present, the lycopene extraction procedure is mainly extracted from plant tomatoes, and there are mainly direct solvent extraction methods, enzyme reaction methods, microwave extraction methods, carbon dioxide supercritical extraction, and ultrasonic extraction methods.
1. Solvent direct extraction method
Lycopene is not soluble in water, but can be dissolved in ether, petroleum ether, phenylacetone, easily soluble in chloroform, carbon disulfide, benzene and other organic solvents. The direct solvent extraction method does not require complicated equipment. It is a very good method for the industrial production of crude lycopene products such as lycopene oleoresin. And its single specific amount of viscosity, simple and fast. Generally, pretreatment of tomato or purification of oleoresin is usually required before dipping.
2. Enzyme reaction method
The enzymatic reaction method mainly uses lycopene to extract the lycopene from the tomato skin. Under alkaline conditions, the tomatoes are beaten and crushed or the by-products of tomato and the process is used to react the pectinase and cellulase in the tomato skin, decompose pectin and cellulose, and make the lycopene protein complex from the cells Dissolve. Compared with the organic solvent extraction method, the enzyme reaction method greatly reduces the extraction time, and at the same time, the extraction rate of lycopene is also greatly improved.
3. Microwave extraction method
Microwave extraction method is a ultra-high frequency electromagnetic wave with a strong electromagnetic propagation effect. And this lycopene extraction procedure can achieve uniform and rapid heating at the same time inside and outside the particle. Microwave extraction of lycopene is beneficial to the penetration of organic solvents through the cell wall and cell membrane of tomato, and to better dissolve the extract from the cells, thereby obtaining a higher lycopene extraction rate. This method can not only reduce the production time interval, save energy and operating costs, obtain a relatively high extraction rate, and is very suitable for environmental protection requirements.
4. Carbon dioxide supercritical extraction method
Carbon dioxide supercritical extraction method is a new separation technology in the food industry, using the relationship between the solubility of supercritical fluids and their density, that is, the use of supercritical fluids' solubility is affected by their pressure and temperature. Compared with the traditional chemical solvent extraction method, it has unparalleled superiority. The advantage of this method is that it does not use chemical solvents and no pollution. The extraction conditions are very mild, which is very suitable for extracting lycopene. And other heat-sensitive materials have a good early extraction effect on lycopene.
5. Ultrasonic extraction method
The ultrasonic extraction method uses ultrasonic cavitation and vibration to make the tomato cell wall completely rupture, and the entire rupture process is completed in a very short time, which not only accelerates and accelerates the lycopene in tomatoes. Dissolution, while at the same time conducive to the retention of active ingredients. The production equipment used in the ultrasonic extraction method is very simple and easy to operate. Lycopene extraction procedure is not only used to improve efficiency and reduce the short extraction time, but also simple and easy to perform. It is a very effective method for lycopene extraction. In addition, lycopene can be produced by germination and decomposition of microorganisms, chemical synthesis, and high performance liquid chromatography. The production of lycopene have be a hoe topic in the academic world.
