Kev Ua Si Txiav Txim Siab
Kev rho tawm cov tshuaj thev naus laus zis siv cov kua dej (xws li dej, etcanol, thiab lwm yam) kom rho tawm cov tshuaj hauv qab no lawv cov ntsiab lus tseem ceeb. Hom no muaj cov yam ntxwv hauv qab no:
Efficiency:Kev hais txog dej rho tawm muaj kev ua haujlwm siab nyob rau hauv kev rho tawm polyphenolic tshuaj, ua rau cov phiaj xwm nrawm nrawm.
Kev ua phooj ywg ib puag ncig:Dej lossis ethanol feem ntau yog siv los ua cov kuab tshuaj, zam kev siv cov tshuaj lom organic thiab txo cov pa phem ib puag ncig.
Kev Siv:Nws yog qhov haum rau cov tshuaj phenolic phenolic sib xyaw los ntawm cov txiv ntseej, xws li txiv ntseej iab iab thiab hydroxytystols.
Supercritical Extraction
Supercritical rho tawm thev naus laus zis siv cov kua dej (xws li cov roj carbon dioxide) kom nqa tawm cov kev cuam tshuam hauv lawv cov ntsiab lus tseem ceeb. Nws cov txiaj ntsig suav nrog:
Siab Xaiv:Los ntawm kev kho qhov kub thiab lub zog, qhov rho tawm ntawm cov khoom siv tshwj xeeb tuaj yeem tswj tau qhov tseeb, ua rau nws tsim nyog rau cov tshuaj tshwj xeeb ntawm cov txiv ntseej.
Tsis muaj cov kuab tshuaj seem:Nyob rau hauv cov txheej txheem ntawm supercritical carbon dioxide extraction, yuav luag tsis muaj organic cov kuab tshuaj yog siv, zam qhov teeb meem ntawm cov kuab tshuaj.
Kev tiv thaiv ntawm cov khoom siv:Tus mob me ntawm cov kua dej supercritical pab tiv thaiv kev ua si ntawm tshav kub {}} rhiab phenolic tebchaw.
Zuag qhia tag nrho, yog tias lub hom phiaj yog kom txuag cov phenolic tshuaj ntawm cov txiv ntseej kev tiv thaiv thiab tswj tus nqi, subcritical extraction yog qhov kev xaiv zoo. Txawm li cas los xij, yog qhov kev xaiv siab yog qhov yuav tsum tau ua rau cov tshuaj lom tshwj xeeb phenmolic tshuaj thiab muaj cov tshuaj tiv thaiv siab, cov kev tshem tawm supercritical yog qhov tsim nyog.
