Txoj Cai Ua Haujlwm Thiab Qhov Zoo Ntawm Ultrasonic Extraction Technology

Ultrasonic extraction thev naus laus zis yog cov txheej txheem nyiam rau kev cais cov tshuaj bioactive los ntawm cov nroj tsuag. Ultrasound hais txog cov tshuab suab tsis muaj zaus tshaj 20 kHz tab sis tsawg dua 10 MHz. Ultrasonic extraction feem ntau siv ntau zaus me me (16 kHz-100 kHz), raws li ntau zaus tuaj yeem ua rau lub zog ntau dhau, uas tuaj yeem ua rau kev puas tsuaj ntawm cov khoom siv hauv cov nroj tsuag.

Sonication enables tiav extraction, uas ua rau siab extraction yields nyob rau hauv luv luv extraction lub sij hawm. Raws li txoj kev rho tawm tau zoo, ultrasonic extraction txuag tau ob qho tib si nqi thiab lub sijhawm thaum muab cov khoom zoo siab - zoo rau kev siv hauv cov khoom noj, tshuaj, thiab tshuaj.

txoj cai ua haujlwm

Ultrasonic extraction yog raws li lub hauv paus ntsiab lus ntawm kev ua hauj lwm ntawm ultrasonic cavitation thiab yog ib tug purely mechanical kho. Zoo ib yam li siab shear mixers, sonotrodes tsim txhua yam shear rog tsuas yog nyob rau hauv cov txheej txheem nruab nrab. Ultrasonic extraction nws tus kheej yog ib qho uas tsis yog -thermal, tshuaj- cov txheej txheem rho tawm dawb.

Ultrasonic cavitation yog sonic los yog ultrasonic cavitation uas tshwm sim ntawm lub zog siab, raws li rov qab siab thiab qis - lub voj voog siab. Hloov siab thiab qis - lub voj voog siab ntawm sonication 20, 000 zaug hauv ib ob tsim lub zog shear hnyav thiab cov dav hlau ua kua. Qhov kev ntxhov siab no kov yeej qhov kev xaiv ntawm daim nyias nyias, perforates thiab cuam tshuam cov phab ntsa ntawm tes, thiab ua rau siab - thauj khoom zoo ntawm cov cell sab hauv thiab cov kuab tshuaj nyob ib puag ncig. Nrog ultrasonic extraction, ntau yields thiab luv luv extraction sij hawm yuav ua tau tiav. Txij li thaum ultrasonic extraction yog ib qho txheej txheem rov ua dua, cov txiaj ntsig rho tawm tuaj yeem rov ua dua rau cov txheej txheem rho tawm zoo.

Ultrasonic cavitation tuaj yeem ua rau hauv cheeb tsam huab cua xws li kev sib txawv siab heev thiab siab shear rog. Thaum cov npuas cavitation tawg mus rau saum npoo ntawm cov khib nyiab (xws li cov khoom, cov hlwb, cov ntaub so ntswg, thiab lwm yam), microjets thiab inter-particle sib tsoo tuaj yeem tsim cov teebmeem xws li particle rupture, sonoporation (perforation ntawm cell phab ntsa thiab daim nyias nyias), thiab cellularity. Tsis tas li ntawd, qhov bursting ntawm cavitation npuas nyob rau hauv cov kua xov xwm tsim turbulence thiab agitation, uas pab txhawb loj hloov ntawm lub sab hauv ntawm lub xov tooj ntawm tes thiab ib puag ncig hnyav. Ultrasonic hluav taws xob yog ib txoj hauv kev zoo los txhim kho cov txheej txheem hloov loj, raws li ultrasound induces cavitation thiab nws cov txheej txheem cuam tshuam, xws li micromotion induced los ntawm cov kua dav hlau, compression thiab decompression nyob rau hauv cov ntaub ntawv, thiab tom qab cell phab ntsa cuam tshuam.

qhov zoo

Ultrasonic extraction tuaj yeem txo cov kuab tshuaj thiab ua kom cov kuab tshuaj ntau dua. Qhov no txhais tau hais tias ultrasonic extraction nce extraction yields thiab ua rau noj qab haus huv extracts. Qhov no yog vim nws cov yam ntxwv ntawm kev ua haujlwm ntawm qhov kub thiab txias, uas tuaj yeem tsis tsuas yog txo cov cua sov los ntawm qhov kub thiab txias, tab sis kuj tseem zam cov vaporization ntawm cov khoom vim cov ntsiab lus boiling tsawg thiab tswj cov khoom siv roj ntsha. Ultrasonic extraction yog ib daim ntawv thov yooj yim, nyab xeeb, thiab tswj tau meej. Raws li txoj kev uas tsis yog -thermal extraction method, sonication tuaj yeem ua tau ntawm qhov kub thiab txias, yog li zam qhov degradation ntawm thermally rhiab heev, thermally unstable tshuaj. Ultrasonic extraction kuj muaj peev xwm txo tau lub sij hawm ntau lawm, raws li kev mus ncig ultrasonic nthwv dej cuam tshuam cov phab ntsa ntawm tes, yog li txo lub sij hawm hloov ntawm cov khoom nquag ntawm cov khoom cog rau cov kuab tshuaj.

Cov teebmeem ntawm Ultrasonic Extraction

Ultrasonic Cell cuam tshuam thiab nce loj Hloov Ultrasound tuaj yeem pab cov txheej txheem rho tawm los ntawm kev cuam tshuam ntawm tes thiab txhim kho huab hwm coj hloov pauv hauv cov ciam teb ib puag ncig cov khoom matrix. Raws li perforation ntawm cov phab ntsa ntawm tes thiab daim nyias nyias, ultrasound tuaj yeem txhim kho permeability ntawm phab ntsa ntawm tes thiab daim nyias nyias, feem ntau yog theem nrab ua ntej cov hlwb puas tag los ntawm ultrasound.

Cov teebmeem ntawm ultrasound-induced cavitation, xws li kub thiab siab sib txawv, shock waves, shear force, kua dav hlau, thiab microfluidics, txhim khu cov kuab tshuaj nkag mus rau hauv lub cell sab hauv thiab txhim kho huab hwm coj hloov ntawm cov hlwb thiab cov kuab tshuaj, ua rau intercellular cov ntaub ntawv yuav tsum tau xa mus rau cov kuab tshuaj.

Cov ntsiab lus

Ultrasonic extraction technology siv cov cavitation uas ua los ntawm ultrasonic tsis los extract cov khoom xyaw nquag ntawm cov nroj tsuag. Piv nrog rau cov txheej txheem rho tawm, ultrasound- pab txoj kev rho tawm ua kom zoo nkauj dua vim lawv cov txiaj ntsig ntau yam, xws li kev siv hluav taws xob tsawg, lub sij hawm rho tawm luv luv, kev puas tsuaj tsawg dua ntawm cov khoom sib txuas, thiab cov txiaj ntsig siab extraction.
