Txoj kev extraction ntawm resveratrol

Txheej txheem extraction
Cov kuab tshuaj extraction yog ib qho ntawm cov kev siv ntau tshaj plaws extraction ob qho tib si hauv tsev thiab txawv teb chaws. Txoj kev siv cov kuab tshuaj extraction feem ntau muaj peb hom: percolation method, extraction method, thiab reflux method. Feem ntau siv cov kuab tshuaj rau reflux extraction ntawm resveratrol muaj xws li methanol, ethanol, acetone, ethyl acetate, thiab lwm yam. Ntawm lawv, 60% mus rau 90% ethanol aqueous kua yog feem ntau siv rau reflux extraction resveratrol los ntawm thawj cov nroj tsuag. Lwm cov kuab tshuaj tsis tshua siv vim qhov ua haujlwm qis los yog muaj tshuaj lom heev.
Enzymatic extraction
Resveratrol muaj nyob rau hauv ntau cov nroj tsuag nyob rau hauv daim ntawv ntawm resveratrol glycosides, uas yuav enzymatically hydrolyzed rau resveratrol thiab ces muab rho tawm raws li dawb resveratrol. Txoj kev no tuaj yeem ua tiav cov txiaj ntsig siab dua, yog li qee cov kws tshawb fawb tau siv enzymatic hydrolysis los rho resveratrol. Muaj peb qhov chaw ntawm enzymes nyob rau hauv enzymatic extraction: siv cov nroj tsuag derived enzymes, ntxiv lwm enzymes, thiab tsim enzymes los ntawm microbial inoculation.
Microwave extraction
Microwave extraction yog ib txoj hauv kev uas cov noob hlwb nqus lub zog hauv lub microwave hauv lub microwave, ua rau qhov kub thiab txias, nthuav dav, thiab tawg, uas pab txhawb kev tshem tawm cov khoom xyaw nquag ntawm cov nroj tsuag. Txoj kev no feem ntau siv hauv kev tshawb fawb hauv chav kuaj.
Supercritical carbon dioxide rho tawm
Supercritical CO2 extraction yog txheej txheem ntawm kev rho tawm lossis cais qee yam khoom los ntawm kev sib xyaw siv CO2 kua hauv lub xeev supercritical raws li hnyav. Supercritical CO2 yog tus cwj pwm los ntawm cov khoom ruaj khov, tsis muaj tshuaj lom, tsis muaj kuab paug rau ib puag ncig, muaj zog permeability thiab solubility, nrog rau kev hloov pauv tau zoo thiab muaj dej txaus.
