Inventor: YANG RUIJIN
IPC: C11B1/10
Filed: 2018-10-29
Abstract: A water-based oil extraction method and an application of tea saponin for improving the efficiency of a water-based oil extraction method. The method uses water or an ethanol-containing water solution as a medium. A material to be extracted is pulverized, soaked in an extraction agent containing tea saponin at 50-100°C for 0.5-3 h, the pH being adjusted to 8-10, and centrifuged to separate a residue phase, a water phase, an oil phase and an emulsion. The oil phase and the emulsion are collected and demulsified to obtain a clear oil. The tea saponin is contained in the material itself, and enters the water phase during extraction, or is added as an additional component. A tea saponin solution with a concentration of 10-200 g/L is used for oil extraction. The present invention also involves an application, such as using the method to extract oils from a camellia fruit or seed and an oil product obtained by the method. Using a tea saponin-containing water solution for oil extraction can significantly reduce use of the extraction agent, achieves an oil extraction rate of 94% or more, and reduces wastewater production.
