Natural Lycopene Powder has extremely high development value and application prospects in food, beauty and pharmaceutical fields. Do you know how to extract lycopene? This article will introduce you to 4 different extraction methods. Each of these methods has pros and cons.
1. Direct crushing method
Blanch fresh tomatoes directly with water to remove skin and seeds. After that, the skin is dried and pulverized as a coloring powder to color food. This method is convenient and straightforward to operate, but the texture of the obtained product is relatively rough, and the application range is not comprehensive.
2. Organic solvent leaching method
The lycopene can be extracted by taking advantage of its easy solubility in organic solvents. Using petroleum ether, acetone, dichloromethane, methyl acetate four solvents to extract lycopene. The extraction effect of methyl acetate was the best. The mass concentration of lycopene in the concentrated crude extract was 6.4-7.5 mg/100 mL. Tomato tissue cells were saponified with sodium carbonate prior to extraction. This method results in the complete release of Natural Lycopene Powder. After that, extraction is carried out by leaching method, which greatly shortens the extraction time, and the extracted product has a high content.
3. Enzyme extraction method
The method of releasing and extracting lycopene by the tomato skin's own enzymes or artificially added enzymes. The study found that the optimal enzyme concentration ratio when extracting lycopene from tomato was pectinase: cellulase = 4:1. The amount of enzyme added is 0. 5%. Pretreatment with absolute ethanol for 4 h could improve the extraction rate of lycopene.
4. Supercritical fluid extraction
The method has simple process and low energy consumption. It has the advantages of non-toxic and low price. It uses the principle of low temperature, so it can be used to extract heat-sensitive polar components. Pretreatment can also improve the extraction rate and purity of Natural Lycopene Powder. Then use supercritical carbon dioxide as the fluid. The extraction rate can reach 93. 81%. The disadvantage of low extraction rate of traditional methods is solved.
