Ib txoj hauv kev zoo thiab muaj txiaj ntsig Extraction rau Ginsenosides Thiab Polysaccharides siv Ultrasonic Extraction.

Ginseng cov tshuaj thiab khoom noj muaj txiaj ntsig tau ntev tau lees paub los ntawm ntau txhiab xyoo ntawm cov tshuaj suav tshuaj thiab kev tshawb fawb niaj hnub no. Ginsenosides thiab ginseng polysaccharides yog cov khoom xyaw tseem ceeb hauv ginseng, ua rau lawv nyiam cov khoom lag luam hauv cov khoom noj thiab tshuaj pleev ib ce. Yuav ua li cas kom zoo thiab maj mam rho tawm ob cov khoom xyaw nquag, ua kom lawv cov bioactivity thaum txo cov nqi tsim khoom thiab txhim kho kev ua haujlwm, ib txwm yog qhov teeb meem tseem ceeb hauv kev lag luam ginseng sib sib zog nqus. Qhov tshwm sim ntawm ultrasonic extraction technology tau tawg tag nrho cov kev txwv ntawm tsoos extraction txheej txheem. Nrog nws cov txiaj ntsig thev naus laus zis tshwj xeeb, nws tau dhau los ua cov thev naus laus zis tseem ceeb hauv kev ua haujlwm niaj hnub ginseng sib sib zog nqus, muab cov kev daws teeb meem tshiab rau qhov loj - nplai, siab - zoo extraction ntawm ginsenosides thiab polysaccharides.

Piv rau cov txheej txheem rho tawm ib txwm muaj, cov txiaj ntsig tseem ceeb ntawm ultrasonic extraction thev naus laus zis tau hloov pauv cov txiaj ntsig thiab kev ua tau zoo ntawm cov txheej txheem rho tawm, qhia txog nws qhov tseem ceeb sib txawv ntawm cov txheej txheem ib txwm ua thiab dhau los ua tus yuam sij rau nws txoj kev vam meej. Lub hauv paus ntsiab lus tseem ceeb ntawm ultrasonic extraction technology yog siv lub "cavitation nyhuv" generated los ntawm ultrasound (feem ntau yog 20-100 kHz) nyob rau hauv lub extraction hnyav, nrog rau cov neeg kho tshuab kev co thiab thermal cuam tshuam, kom ua tau zoo cuam tshuam ntawm ginseng cell phab ntsa thiab sai dissolution ntawm active cov khoom xyaw. Tshwj xeeb, thaum ultrasound propagates nyob rau hauv ib tug kua nruab nrab, nws generates countless me npuas npuas. Cov npuas no nthuav dav sai thiab tawg sai sai nyob rau hauv lub zog ntawm ultrasonic teb.

Qhov tawg tam sim no ua rau muaj qhov kub thiab txias hauv cheeb tsam (txog ntau txhiab degrees Celsius) thiab kev kub ntxhov siab (txog pua pua ntawm cov cua), ua rau muaj zog microjets thiab shear rog. Qhov kev quab yuam no tuaj yeem cuam tshuam ncaj qha rau cov qauv cellulose ntawm ginseng cell phab ntsa, tsim cov pores me me hauv cov phab ntsa ntawm tes thiab daim nyias nyias, lossis txawm tias lawv tawg tag. Qhov no tso cai rau cov khoom xyaw nquag xws li ginsenosides thiab polysaccharides nyob rau hauv lub hlwb kom tso tawm sai sai thiab tag nrho rau hauv cov kuab tshuaj extraction, txhim kho kev ua haujlwm ntawm qhov chaw.

Dhau li ntawm cov tub ntxhais cavitation nyhuv, lub uniqueness ntawm ultrasonic extraction technology kuj nyob rau hauv nws "mob, npaum, meej, thiab controllable" yam ntxwv. Nws tuaj yeem ua tau ntawm chav tsev kub lossis qhov kub tsis tshua muaj (40-60 degree) yam tsis muaj qhov siab ntev -kub cua sov, ua kom zoo tshaj plaws ntawm kev khaws cov bioactivity ntawm ginsenosides thiab polysaccharides thiab ua kom zoo thiab ua tau zoo ntawm cov khoom rho tawm. Lub caij no, cov kev txwv xws li ultrasonic zaus, lub zog, lub sij hawm rho tawm, thiab cov khoom siv - rau - kua piv yuav raug tswj tau meej. Extraction tej yam kev mob yuav optimized raws li hom ntawm ginseng raw khoom (tshiab ginseng, qhuav ginseng, ginseng stems thiab nplooj, thiab lwm yam), particle loj, thiab purity yuav tsum tau ntawm lub hom phiaj cov khoom (saponins los yog polysaccharides), ua tiav "ntawm-thov extraction"- cov txheej txheem ib txwm muaj. Tsis tas li ntawd, ultrasonic extraction tshuab siv tsuas yog 50% -70% ntawm cov kuab tshuaj piv rau cov txheej txheem ib txwm muaj, nrog rau qhov hnyav rov qab ntau dua 90%. Qhov no tsis yog tsuas yog txo cov nqi tsim khoom tab sis kuj txo qis ib puag ncig cov pa phem los ntawm cov kuab tshuaj emissions, ua raws li kev tsim kho lub tswv yim ntawm kev tsim ntsuab niaj hnub.

Los ntawm qhov kev xav ntawm cov txiaj ntsig tshwj xeeb extraction, qhov zoo ntawm ultrasonic extraction technology yog tshwj xeeb tshaj yog muaj tseeb. Kev sim cov ntaub ntawv qhia tau hais tias siv ultrasonic extraction thev naus laus zis los extract ginsenosides tuaj yeem ua tiav qhov kev rho tawm ntawm ntau dua 8%, deb tshaj li 5.01% ntawm cov dej ib txwm rho tawm thiab dej cawv los nag, thiab 30% -65% siab dua Soxhlet extraction. Lub sij hawm rho tawm tsuas yog 20-60 feeb, piv rau ob peb teev hauv cov txheej txheem ib txwm ua, txo lub sijhawm los ntawm 50% -85%, txhim kho kev ua haujlwm zoo. Hauv ginseng polysaccharide extraction, ultrasonic extraction tshuab kuj qhia tau zoo heev. Nrog lub zog ultrasonic ntawm 200W, lub sijhawm ultrasonic ntawm 30 feeb, thiab cov khoom siv - rau- kua piv ntawm 1:50, polysaccharide extraction tus nqi nce mus txog qib siab, thiab cov polysaccharides rho tawm muaj ntau dua purity nrog txo qis impurity cov ntsiab lus piv rau cov txheej txheem ib txwm ua, ua rau kom tsis txhob muaj qhov nyuaj. Qhov tshwj xeeb zoo ntawm kev ua "ua tau zoo, muaj txiaj ntsig zoo, lub zog{19}}txuag, thiab tus phooj ywg ib puag ncig" tau ua rau kev hloov pauv sai ntawm cov txheej txheem ib txwm siv los ntawm kev siv tshuab ultrasonic extraction, uas tam sim no tau siv dav hauv ntau yam kev lag luam niaj hnub ginseng sib sib zog nqus.

Hauv kev tsim khoom niaj hnub no, daim ntawv thov ntawm ultrasonic ginsenoside thiab polysaccharide extraction technology tau npog ntau yam xws li tshuaj, khoom noj qab haus huv, khoom noj khoom haus, thiab tshuaj pleev ib ce, tsim ib tug loj - nplai, txheem txheej txheem ntau lawm thiab ua ib tug tseem ceeb tsav tsheb rau lub siab - kev loj hlob zoo ntawm ginseng kev lag luam.
