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

Abstract

The invention discloses a method for extracting betel nut biotin form fresh betel nuts. The method comprises the steps as follows: the fresh betel nuts are sorted, cleaned and smashed, water is added, 0.1%-1% of cellulose is added for biological splitting, the pH is adjusted to 2-7, the mixture is kept standing for 0.5-4 h, and plate filtration is performed, so that an extraction solution is obtained; the extraction solution is subjected to high-speed centrifugal separation (3000-30000 r min), and impurities and macromolecular substances are removed, so that a solution is obtained; the solution is subjected to vacuum continuous dehydration at a temperature below 60 DEG C, so that a solid substance is obtained; and the solid substance is smashed, subjected to 30-120 meshes and examined, so that the betel nut biotin is obtained. According to the method, the operation is simple, the technology temperature is below 60 DEG C, alkaloid and general flavone are taken as quality control indexes, beneficial ingredients of the betel nuts are fully extracted, the betel nut biotin extraction rate is high, and the method is suitable for industrial production. No furnace is needed, no organic solvent is related, and no waste liquid or waste gas is discharged. Production slag is betel nut fibers which are precious raw materials for a high-grade fiber board 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 betel nut (Areca catechu L) is the ripe fruit of areca catechu, a plant belonging to the genus Areca 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 add...
