Ultrasonic pab Extraction

Ultrasonic pab Extraction

Kev sib cuam tshuam ntawm lub siab tsis (ultrasound) nrog cov kua nruab nrab ua rau tsim cov kab noj hniav hauv cov kua. Cov kab noj hniav no tau txais kev sib txuas tas mus li thiab tsis tshua muaj tshwm sim thaum lawv cuam tshuam nrog lub voj voog zoo thiab tsis zoo. Qhov no mus txog rau thaum cov kab noj hniav mus txog lub vojvoog tseem ceeb, uas yog txiav txim los ntawm qhov zaus ntawm ultrasound. Lub implosion ntawm npuas tsim ib lub zos kub ntawm 5000K thiab pressures siab li 1000atm.

Ultrasonic extraction ntawm tsoos suav tshuaj thiab tej yam ntuj tso tshuaj: ntxiv ib tug extraction hnyav (dej, ethanol los yog lwm yam organic hnyav, thiab lwm yam) Lub transducer vibrator yog bonded rau sab nrauv phab ntsa los yog lub vibrator yog kaw nyob rau hauv ib lub thawv stainless hlau thiab muab tso rau hauv lub thawv. ; Thaum lub tshuab hluav taws xob ultrasonic tau qhib, lub vibrator emits ultrasonic nthwv dej rau hauv cov kuab tshuaj extraction, thiab 'cavitation nyhuv' thiab cov neeg kho tshuab ua los ntawm ultrasonic nthwv dej hauv cov kuab tshuaj extraction tuaj yeem ua rau lub cell phab ntsa ntawm cov khoom siv tshuaj, yog li ntawd. Cov khoom xyaw nquag yog nyob rau hauv lub xeev dawb thiab yaj rau hauv cov kuab tshuaj extraction. Ntawm qhov tod tes, nws tuaj yeem ua kom lub zog molecular ntawm cov kuab tshuaj extraction, kom cov kuab tshuaj extraction thiab cov khoom xyaw nquag hauv cov khoom siv tshuaj tuaj yeem sib cuag sai, yaj thiab sib tov. Ultrasonic Assisted Extraction (tseem hu ua extraction) yog siv los ntawm cov neeg tshiab los extract cov ntsiab lus zoo ntawm Suav tshuaj ntsuab thiab ntau yam tsiaj thiab nroj tsuag vim nws qhov tshwj xeeb zoo ntawm qhov kub thiab txias, siab extraction tus nqi thiab lub sij hawm luv luv extraction. Nws yog lwm txoj hauv kev rau cov txheej txheem shearing. Niaj hnub nimno high-tech txhais tau tias kom ua tiav high-efficiency, txuag zog thiab ib puag ncig tus phooj ywg extraction

Nqe lus piav qhia:

Ultrasound yog ib txoj kev ua tau zoo heev nyob rau hauv tiam thiab siv cov ntaub ntawv nano loj. Feem ntau, ultrasonic cavitation hauv cov kua yuav ua rau sai thiab ua tiav degassing: pib ntau yam tshuaj lom neeg los ntawm kev tsim cov tshuaj dawb ions (radicals); ceev cov tshuaj tiv thaiv los ntawm kev ua kom yooj yim sib xyaw ntawm cov tshuaj reactants; txhim kho polymerization thiab depolymerization

kev cuam tshuam los ntawm kev sib cais ib ntus lossis los ntawm kev rhuav tshem cov tshuaj lom neeg ruaj khov hauv cov saw hlau polymeric; nce emulsification tus nqi; txhim kho tus nqi diffusion; ua kom muaj zog emulsions los yog cov khoom tawg yooj yim ntawm micron-loj lossis nano-size cov ntaub ntawv; pab tshem tawm cov tshuaj xws li enzymes ntawm tsiaj, nroj tsuag, poov xab, los yog kab mob hlwb; tshem tawm cov kab mob los ntawm cov ntaub so ntswg; thiab thaum kawg, erode thiab rhuav tshem cov kab mob uas cuam tshuam, nrog rau cov kab mob microorganisms. Ultrasound tuaj yeem kuaj hauv chav kuaj thiab lub rooj zaum saum toj kawg nkaus ua ntej cov txiaj ntsig tau ntsuas mus txog qib kev lag luam.

Daim ntawv thov:

"Green" kev sib cais thev naus laus zis tau tshwm sim los ua lwm txoj hauv kev rau cov organic solvent-based extraction vim lawv qhov kev xav tau ntawm cov kuab tshuaj txo qis, thiab lub sijhawm luv ntawm cov txheej txheem. Kev rho tawm cov txheej txheem nrog ultrasound, microwave, enzymes, thiab supercritical CO2 yog cov txheej txheem kev sib cais tam sim no. Tshwj xeeb tshaj yog, qhov kev pab cuam ultrasound extraction tuaj yeem txhim kho kev hloov pauv loj, yog li txo lub sijhawm ntawm kev rho tawm thiab txo qis kev noj cov kuab tshuaj hauv kev sib piv nrog cov qauv kev rho tawm.

Ultrasound-pab extraction tau lees paub tias yog cov txheej txheem ua tau zoo dua li cov kev rho tawm ib txwm siv, ib zaug nws txhawb nqa cov txiaj ntsig zoo ntawm cov phenolic tebchaw cuam tshuam nrog lub sijhawm luv luv thiab qis qis ntawm cov kuab tshuaj. Acidified dej yog ib qho extracting hnyav npaum li ethanol ntawm extraction phenolic tebchaw thiab anthocyanins los ntawm jussara txiv hmab txiv ntoo. Cov txheej txheem teb saum npoo tau ua tiav siv los ua kom zoo dua lub sijhawm, ethanol concentration thiab txiv hmab txiv ntoo: hnyav piv koom nrog hauv ultrasound-pab extraction ntawm phenolic tebchaw thiab anthocyanins los ntawm jussara txiv hmab txiv ntoo thiab blueberries. Txoj kev tshawb no qhia tau hais tias cov txheej txheem ultrasound-pab extraction yuav tsum tau ua kom zoo los ntawm kev noj cov yam ntxwv tshwj xeeb ntawm txhua cov zaub mov matrix rau hauv tus account. Lub dependence ntawm cov txheej txheem extraction ntawm cov tshuaj muaj pes tsawg leeg thiab solubility ntawm txiv hmab txiv ntoo tsim nyog kev tshawb fawb ntxiv.

Daim ntawv thov tswv yim: Ultrasound-pab extraction yog ib qho kev xaiv rau cov qauv kev rho tawm vim nws tuaj yeem txhim kho qhov hloov pauv loj, txo lub sijhawm rho tawm thiab siv hnyav. Yog li, phenolic extraction efficiency ntawm cov pa thiab cov kev pab cuam ultrasound raws li zoo raws li optimize lub ultrasound-pab extraction tsis siv lub teb nto txheej txheem. Ultrasound-pab extraction tau zoo dua li cov pa extraction ntawm phenolic tebchaw los ntawm ob lub txiv hmab txiv ntoo. Cov dej acidified tau zoo li ethanol hauv kev rho tawm cov phenolic tebchaw los ntawm jussara txiv hmab txiv ntoo.
