Study on Extraction Process and Bioactivity of Gingerol from Ginger
Gingerol is a compound in ginger and has various bioactivity effects such as anti-inflammation,antioxidation,inhibiting microorganisms and relieving indigestion.In the traditional extraction method of gingerol,organic solvents such as ether or ethyl acetate are usually used.After extraction,organic solvents will remain in gingerol and affect the purity and quality of gingerol.Based on this,in this study,the effects of four extraction processes such as traditional solvent extraction method,Soxhlet extraction method,ultrasonic-assisted extraction method and pulsed electric field-assisted method on the extraction amount of gingerol are investigated,and then the effect of processing technology on the gingerol extraction amount in ginger under different conditions is studied.The research results show that when pulsed electric field-assisted method is used to extract gingerol from ginger,the extraction amount is the highest,the required time is the shortest,and the extraction temperature is the lowest,making it a green and low-cost technology.In addition,the optimal processing technology for extracting gingerol from ginger using pulsed electric field-assisted method is ethanol concentration of 80％,pulse width of 20 µs,pulse times of 20 times and electric field intensity of 2.0 kV/cm.
