Qhov sib txawv tseem ceeb ntawm cov kua dej supercritical extraction thiab microwave assisted extraction yog hais tias nyob rau hauv supercritical kua extraction txoj kev, lub extraction yog ua los ntawm ib tug supercritical kua li extracting hnyav, whereas nyob rau hauv microwave pab extraction, extraction yog ua los ntawm microwave zog.
Supercritical kua extraction thiab microwave assisted extraction yog ob hom kev tsom xam tseem ceeb. Supercritical kua extraction los yog SFE yog ib txoj kev xaiv heev uas peb siv cov kua pressurized li cov kuab tshuaj. Microwave-pab extraction los yog MAE yog cov txheej txheem siv rau kev rho tawm cov khoom siv los ntawm cov nroj tsuag tshuaj siv lub zog microwave.
Dab tsi yog Supercritical Fluid Extraction?
Supercritical kua extraction lossis SFE yog ib txoj hauv kev xaiv uas peb siv cov kua nplaum ua kuab tshuaj. Nws yog txheej txheem kev tshuaj xyuas uas cais ib feem ntawm lwm qhov siv cov kua dej supercritical ua cov kuab tshuaj extracting. Cov khoom qub yog hu ua extractant, thiab tom kawg yog hu ua matrix.
Feem ntau, qhov kev rho tawm no yog ua los ntawm cov khoom matrix, tab sis nws kuj tuaj yeem ua los ntawm cov kua. Ntxiv mus, peb tuaj yeem siv txoj kev no los ua tus qauv npaj cov kauj ruam rau kev siv tshuaj ntsuam xyuas. Peb kuj tuaj yeem siv nws hauv cov ntawv loj loj los rub cov khoom tsis xav tau los ntawm cov khoom lossis los sau cov khoom xav tau. Ib qho piv txwv zoo ntawm kev tshem tawm cov khoom tsis xav tau yog decaffeination. Ib qho piv txwv ntawm kev sau cov khoom xav tau yog cov roj yam tseem ceeb.
Cov kua dej siv ntau tshaj plaws yog carbon dioxide. Qee zaum nws hloov kho ua ntej siv. Kev hloov kho yog ua tiav siv ethanol lossis methanol. Cov txheej txheem rho tawm uas peb yuav tsum tau siv rau cov pa roj carbon dioxide supercritical yog qhov kub siab tshaj qhov kub siab tshaj (31 degrees Celsius) thiab lub siab tseem ceeb (74 bar). Txawm li cas los xij, qhov sib ntxiv ntawm cov kev hloov pauv tuaj yeem hloov kho cov xwm txheej no.
Microwave Assisted Extraction yog dab tsi?
Microwave assisted extraction lossis MAE yog cov txheej txheem siv rau kev rho tawm cov khoom siv los ntawm cov nroj tsuag tshuaj siv lub zog microwave. Ntawm no, lub zog microwave yog siv los ua kom sov cov kuab tshuaj uas muaj cov qauv. Yog li ntawd, cov analytes muab faib los ntawm ib tug qauv matrix rau hauv cov kuab tshuaj.
Nws yog ib txoj hauv kev zoo uas muab cov khoom xyaw ntuj los ntawm cov nroj tsuag nyoos. Txoj kev no kuj tso cai rau cov organic tebchaw muab rho tawm sai dua piv rau cov txheej txheem rho tawm.
Muaj ntau qhov zoo ntawm txoj kev no dhau ntawm txoj kev soxhlet.
- Txo lub sijhawm rho tawm
- Txhim kho yield
- Zoo qhov tseeb
- Haum rau cov khoom siv thermolabile
Thaum xav txog txoj hauv kev rho tawm, lub hom phiaj rau lub tshuab cua sov microwave yog feeb microscopic kab ntawm noo noo hauv cov nroj tsuag qhuav. Feem ntau, sab hauv ntawm qhov cub muaj qhov kub thiab txias. Qhov kub siab no tuaj yeem ua rau lub cev qhuav dej ntawm cellulose thiab qhov no, tig mus, txo cov neeg kho tshuab lub zog. Cov kauj ruam tseem ceeb ntawm MAE txoj kev yog raws li hauv qab no.
- YMicrowave hluav taws xob
- Moisture evaporation
- Tsim kom muaj lub siab loj heev ntawm phab ntsa cell
- Qhov no ua rau o ntawm cov nroj tsuag o
- Rupturing ntawm cell
- Kev tshem tawm ntawm phyto-cov khoom siv
Qhov txawv ntawm Supercritical Fluid Extraction thiab Microwave Assisted Extraction yog dab tsi?
Supercritical kua extraction (SFE) yog ib txoj kev xaiv heev uas cov kua yog pressurized raws li cov kuab tshuaj thaum microwave assisted extraction (MAE) yog ib tug txheej txheem rau kev rho tawm ntawm active Cheebtsam los ntawm cov tshuaj nroj tsuag siv microwave zog. Qhov sib txawv tseem ceeb ntawm supercritical kua extraction thiab microwave-pab extraction yog tias supercritical kua extraction txoj kev siv ib tug supercritical kua raws li cov extracting hnyav, whereas microwave assisted extraction siv microwave zog rau extraction.
Cov hauv qab no infographic nthuav tawm qhov sib txawv ntawm cov kua dej supercritical extraction thiab microwave-pab extraction hauv daim ntawv tabular rau kev sib piv ntawm ib sab.
Summary – Supercritical Fluid Extraction vs Microwave Assisted Extraction
Kev rho tawm yog cov txheej txheem kev tshuaj xyuas los cais cov yam xav tau los ntawm kev sib xyaw ntawm cov khoom sib xyaw. Supercritical kua extraction thiab microwave assisted extraction yog ob hom kev tsom xam tseem ceeb. Qhov sib txawv tseem ceeb ntawm supercritical kua extraction thiab microwave-pab extraction yog tias supercritical kua extraction txoj kev siv ib tug supercritical kua raws li cov extracting hnyav, whereas microwave assisted extraction siv microwave zog rau extraction.
