Method for extracting tea seed soil and tea saponin through microwave reinforcement in same process

Abstract

The invention relates to a method for extracting tea seed soil and tea saponin through microwave reinforcement in the same process. The method comprises the following steps: husking and crushing tea seeds, carrying out microwave irradiation for a period of time, filling into an extraction kettle of a supercritical fluid extraction device, extracting tea seed powder by utilizing supercritical CO2 fluid, and then discharging extraction liquor from a separation kettle to obtain tea seed oil; and then adding low alcohol-water solution in a certain proportion through an entrainer feed inlet of the supercritical fluid extraction device, changing the extraction temperature and extraction pressure, extracting for a period of time by reutilizing the supercritical CO2 fluid, and then discharging the extraction liquid from the separation kettle to obtain tea saponin alcohol solution. The method combines the advantages of microwave pretreatment technology and supercritical CO2 fluid extraction technology, high-quality tea seed oil and high-activity tea saponin can be obtained sequentially in the same one supercritical CO2 fluid extraction device, the production technique flow can be simplified, and the production efficiency can be improved.

Description

technical field

[0001] The invention belongs to the field of deep food processing, and in particular relates to a microwave-intensified simultaneous extraction method for tea seed oil and tea saponin. Background technique

[0002] Camellia oleifera is one of the four woody edible oil source tree species with the same reputation as oil palm, olive and coconut. Camellia oleifera in my country is rich in resources, and the area of ​​camellia oleifera forest accounts for more than 80% of the area of ​​woody edible oil plants, mainly distributed in mountainous and hilly areas in southern my country. Tea seed oil made from camellia oleifera seed is a high-quality health-care edible oil with nutritional value, frying function, and physiological effects that exceed ordinary bulk oils (such as soybean oil, rapeseed oil, palm oil, and cottonseed oil). Tea saponin is a natural surfactant with excellent foaming and emulsifying properties, antibacterial, anti-inflammatory, insecticidal ...
