A kind of method extracting betel nut biotin from fresh betel nut

Abstract

The invention discloses a method for extracting areca nut biotin from fresh betel nuts. The method is to sort fresh betel nuts, clean them, break them, add water, add 0.1% to 1% cellulase for biolysis, adjust the pH to 2 to 7, let them stand for 0.5 to 4 hours, and filter them with plates and frames to obtain extracts; High-speed centrifugation (3000-30000rmin) to remove impurities and macromolecular substances to obtain a solution; the above solution was continuously dehydrated in vacuum below 60°C to obtain solids, crushed, passed through 30-120 meshes, and tested to obtain areca nut biotin. The method is simple to operate, the process temperature is below 60°C, and the alkaloids and total flavonoids are used as quality control indicators, the beneficial components of the betel nut are completely extracted, the biotin acquisition rate of the areca nut is high, and the method is suitable for industrial production. No boiler is needed, no organic solvent is involved, no waste liquid and exhaust gas are discharged. The production waste is betel nut fiber, which is a precious raw material for high-grade fiberboard and activated carbon.

Description

technical field [0001] The invention relates to a method for extracting areca nut biotin from fresh betel nuts. Background technique [0002] Fresh areca catechu (Arecacatechu L) is the mature fruit of the areca catechu plant in the palm family. my country is one of the main producing areas of betel nuts in the world, and the planting area and output of areca nuts in Hainan Province account for more than 90% of the total amount of the country (excluding Taiwan). Betel nuts are one of the main sources of income for farmers in the eastern, central and southern mountainous areas of Hainan, and are known as "emeralds" by local farmers. In some countries in Africa, Southeast Asia and my country's Hunan, Hainan, Guangdong, Taiwan and other places, people have the habit of chewing betel nuts. Chewing betel nut can refresh the brain, produce comfort and euphoria, and improve people's endurance. At present, betel nut has become the world's fourth largest addiction after nicotine, ...

AI Technical Summary

Problems solved by technology

The fiber cell structure of betel nut is compact, and the existing public extraction methods of areca nut cannot completely extract flavonoids and other beneficial components surrounded by the cell wall

At the same time, other extractions using organic solvents require large reagent consumption, long cycles, and low extraction rates.

As an emerging technology for extracting bioactive components, enzymatic method has been widely used, but the application of enzymatic technology in the extraction of areca nut flavonoids is rarely reported
