Piv txwv ntawm Molecular Distillation

Molecular Distillationyog ib qho kev sib cais zoo thiab kev ua kom huv si, uas feem ntau yog siv los kho cov kub kub kub, siab viscosity, kub rhiab heev los yog polymer tebchaw. Nws siv qhov sib txawv volatility ntawm molecules los cais thiab purify lub Cheebtsam nyob rau hauv qhov sib tov.

Lub hauv paus ntsiab lus ntawm distillation yog nyob ntawm ob lub ntsiab lus tseem ceeb hauv qab no:

Distillation: Nyob rau hauv tus txheej txheem ntawm distillation, qhov sib tov yog rhuab thiab txhaj rau hauv molecular distillation khoom los ua chav. Chav dej dhau los ntawm cov channel ntev thiab nyias hauv cov khoom siv distillation, uas yog hu ua evaporator. Nyob rau hauv lub evaporator, qhov kub thiab siab yog precisely tswj los xyuas kom meej tias tsuas yog cov molecules nrog qis boiling ntsiab lus evaporate.

Condensation: Chav yog thauj mus rau lub condenser los ntawm lub evaporator, qhov chaw uas nws hu rau qhov chaw txias. Vim qhov kub ntawm cov condenser qis, cov chav hloov pauv mus rau hauv lub xeev ua kua thiab condenses rau hauv cov tee dej ntawm cov condenser. Cov tee dej no tau sau thiab hu ua cov khoom distillation.

Carotenoids yog ib hom pigment tebchaw, uas dav muaj nyob rau hauv cov nroj tsuag, xws li carrots thiab txiv lws suav. Lawv muaj nplua nuj antioxidant zog thiab khoom noj muaj txiaj ntsig, thiab tau siv dav hauv cov khoom noj, cov khoom kho mob, tshuaj pleev ib ce thiab lwm yam. Hauv qab no yog daim ntawv thov ntawm distillation hauv carotenoid extraction:

Kev sib cais ntawm cov carotenoids sib txawv: Carotenoids yog cov sib xyaw ua ke, suav nrog -carotene, -carotene, lutein thiab lwm yam. Los ntawm kev kho qhov kub thiab txias, cov khoom no tuaj yeem sib cais los ntawm molecular distillation. Vim tias ntau hom carotenoids muaj qhov sib txawv, cov khoom tshwj xeeb tuaj yeem ua kom huv thiab muab rho tawm los ntawm distillation.

Txhim kho purity thiab kev ua ub no: Nws tuaj yeem tshem tawm carotenoids los ntawm kev sib xyaw thiab ua kom huv mus rau qib siab dua. Qhov no tseem ceeb heev rau cov khoom carotenoid uas xav tau siab purity, xws li zaub mov thiab tshuaj pleev ib ce kev lag luam. Tsis tas li ntawd, vim hais tias distillation yog nqa tawm ntawm qhov kub thiab txias siab, lub pyrolysis thiab oxidation cov tshuaj tiv thaiv ntawm carotenoids yuav raug txo kom tsawg, thiaj li zoo khaws lawv cov dej num.

Kev tshem tawm impurities: Rau carotenoids muab rho tawm los ntawm cov nroj tsuag, feem ntau muaj lwm cov tebchaw nrog lawv, xws li rog, protein, thiab lwm yam. Los ntawm distillation, carotenoids thiab impurities tuaj yeem sib cais thiab purer carotenoids tau.

Tau txais cov khoom tshwj xeeb: Qee qhov tshwj xeeb carotenoid Cheebtsam tseem ceeb dua hauv qee qhov kev siv, xws li daim ntawv thov -carotene hauv cov xim zaub mov. Los ntawm kev kho qhov tsis sib xws ntawm molecular distillation, cov khoom tshwj xeeb no tuaj yeem xaiv tau muab rho tawm thiab sib cais kom tau raws li qhov xav tau sib txawv.

Molecular distillationtau los ua nyob rau xyoo 1920, thiab nws yog ib qho tshiab kev sib cais tshuab maj mam tshwm sim nrog kev kawm tob ntawm txoj kev xav ntawm cov pa txav hauv lub tshuab nqus tsev thiab kev txhim kho txuas ntxiv ntawm lub tshuab nqus tsev distillation.

Sib txawv ntawm cov txheej txheem distillation ib txwm, cov txheej txheem distillation yog cov txheej txheem txuas ntxiv mus rau hauv lub tshuab nqus tsev siab. Cov txheej txheem no yog txheej txheem distillation uas tsis tuaj yeem hloov pauv, uas yog nqa tawm ntawm qhov kub thiab txias deb ntawm qhov kub ntawm cov khoom ntawm atmospheric siab.

Lub hauv paus ntsiab lus ntawm distillation thev naus laus zis yog qhov sib txawv ntawm cov molecules muaj qhov sib txawv nruab nrab dawb txoj hauv kev vim lawv qhov sib txawv molecular zoo diameters. Los ntawm kev txheeb cais ntawm qhov pom, lub davhlau deb ntawm cov molecules uas khiav tawm ntawm cov kua nto tsis sib tsoo nrog lwm cov molecules txawv. Kev sib cais ntawm distillation yog paub los ntawm kev siv cov cuab yeej uas cov kua molecules khiav tawm ntawm cov kua nto tom qab cua sov, thiab qhov nruab nrab txoj kev dawb ntawm ntau hom molecules txawv tom qab khiav. Piv txwv li, qhov nruab nrab txoj kev dawb ntawm lub teeb molecules yog qhov loj thiab qhov nruab nrab dawb txoj kev ntawm hnyav molecules yog me me, yog li ntawd lub teeb molecules poob rau ntawm condensation nto, thiab hnyav molecules rov qab mus rau lub qub kua nto vim lawv tsis tuaj yeem ncav cuag lub condensation. nto, kom cov sib tov sib cais.

Volatile roj, tseem hu ua cov roj yam tseem ceeb thiab cov roj tseem ceeb, yog cov sib xyaw ua ke nrog cov tshuaj tsw qab tshwj xeeb thiab cov khoom siv tshuaj muab rho tawm los ntawm cov nroj tsuag lossis lwm yam khoom siv ntuj tsim. Volatile roj feem ntau yog cov kua tsis hloov pauv uas muaj zog aroma thiab cov khoom siv tshuaj. Compendium ntawm Materia Medica sau cov ncauj lus kom ntxaws tshaj plaws ntawm kev rho tawm thiab kho cov roj camphor thiab camphor hauv ntiaj teb. Cov roj tsis muaj roj muaj nyob rau hauv cov plaub hau, cov roj chamber, cov kav dej, cov cell secretory los yog resin ducts ntawm cov nroj tsuag, feem ntau nyob rau hauv daim ntawv ntawm cov roj tee, ib co coexist nrog resin thiab mucus, thiab ob peb muaj nyob rau hauv daim ntawv ntawm glycosides.

Lub Cheebtsam ntawm volatile roj yog tsim los ntawm cov nroj tsuag nyob rau hauv cov txheej txheem ntawm metabolism, xws li monoterpenes, esters, aldehydes, ketones, alcohols thiab lwm yam tshuaj. Cov Cheebtsam no pab txhawb rau qhov tshwj xeeb aroma thiab tshuaj thaj chaw ntawm volatile roj. Piv txwv li, cov roj tsis hloov pauv ntawm lemongrass muaj monoterpenes xws li Cyperulene, uas nthuav tawm cov ntxhiab tsw tshiab xws li txiv qaub; Lub volatile roj ntawm rosemary yog nplua nuj nyob rau hauv phenols, ketones thiab aldehydes, uas muaj antibacterial thiab antiviral los, raws li zoo raws li refreshing thiab kev txawj ntse teebmeem.

Volatile roj feem ntau yog siv rau hauv cov txuj lom, zaub mov seasoning, tshuaj pleev ib ce, tshuaj thiab lwm yam lag luam, thiab kuj yog lug siv nyob rau hauv aromatherapy, massage, aromatherapy, da dej ntsev thiab lwm yam teb. Volatile roj tuaj yeem muab rho tawm los ntawm ntau txoj kev, ntawm cov distillation yog ib qho kev siv tshuab.

Yog vim li cas rau daim ntawv thov dav ntawmmolecular distillationyog nws cov txiaj ntsig zoo sib cais, siv dav, cov txheej txheem paub tab thiab tus nqi zoo, thiab nws cov yam ntxwv zoo ib puag ncig thiab ruaj khov. Txawm hais tias nws yog rho tawm roj los ntawm kev lag luam roj av los yog qhov kev thov rau cov khoom ntshiab hauv kev lag luam xws li tshuaj, tshuaj pleev ib ce, thiab khoom noj, distillation thev naus laus zis tuaj yeem ua tiav cov kev sib cais thiab kev rho tawm cov khoom siv purity siab thaum ua tau raws li ib puag ncig. Qhov no ua rau distillation yog ib qho tseem ceeb thiab tseem ceeb sib cais tshuab hauv ntau yam lag luam.
