How does ultrasonic technology revolutionize modern extraction processes?
Cov txheej txheem
    Raws li kev kho mob thiab ntsuab siv lub cev, ultrasonic homogenization technology tau pom cov txiaj ntsig tseem ceeb hauv kev rho tawm hauv xyoo tsis ntev los no. Cov kab lus no qhia txog tus ua haujlwm ntawm ultrasonic hom kev siv cov tshuab xyaw ua ke, thiab ua kom zoo rau nws txoj kev txhim kho yav tom ntej.

    2. Ua ua haujlwm ntawm ultrasonic homogenization technology

    2.1 cavitation kev ua tshuab
    Cov tub ntxhais muaj nuj nqi ntawm ultrasonic homogenization los ntawm cov cavitation nyhuv - Thaum high - siv ultrasonic vuag (feem ntau 20khz - Nyob rau hauv qhov tsis zoo siab ib nrab - voj voog, cov kua tau raug rau tensile ntxhov siab rau daim ntawv me; Nyob rau hauv tom ntej zoo siab ib nrab - voj voog, cov npuas vau sai, ua rau muaj kev kub siab rau hauv zos txog 5mpa. Qhov xwm txheej huab cua no tuaj yeem rhuav tshem lub xovtooj ntawm phab ntsa teeb tsa thiab nce cov kuab tshuaj permeability.

    2.2 Qhov cuam tshuam theem nrab synergistic nyhuv
    Ntxiv nrog rau cov cavitation nyhuv, ultrasound kuj tseem ua ntau yam kev cuam tshuam ntau yam:

    Kev cuam tshuam microjet: Asymmetric npuas tawg ua cov microjetets nrog lub nrawm tshaj 100m / s
    Shear Zog: High - zaus kev co ua tau muaj cov tshuab siv kho tshuab shear zog (txog 10⁴s⁻¹)
    Thermal Effect: Lub Zog Conversion Ua rau muaj kev nce qib me ntsis hauv 50 - 60 ℃)
    Dawb radical nyhuv: · Au · Hon · he · Hon · Hon active active်း radicals yog tsim nyob rau hauv cov dej nruab nrab

    3. Cov chaw thov tseem ceeb

    3.1 extraction ntawm cov nroj tsuag nquag cov khoom xyaw
    Nyob rau hauv extraction ntawm flavonoids, kev pab ultrasonic tuaj yeem ua rau muaj kev rho tawm los ntawm 30 - 50%, thiab lub sijhawm ua kom luv los ntawm ob peb teev mus rau 15 - 30 feeb. Piv txwv li, nyob rau hauv extraction ntawm nplooj, piv nrog cov kev coj noj coj ua, ultrasonic kev kho (4000W) nce lub quercetin tawm los ntawm 2.4% rau 3.4%.
    Qhov kev rho tawm ntawm polyphenols tseem tau txais txiaj ntsig ntau. Lub hydroxytrosol tawm los ntawm cov txiv ntseej tom qab ultrasonic rho tawm (25% qhov nce ntxiv) rau 20 teev, thiab antioxidant kev ua tau ntau dua.

    3.2 daim ntawv thov hauv kev lag luam khoom noj khoom haus
    Nyob rau hauv daim teb ntawm cov roj tawm, ultrasonic pretreatment tuaj yeem nce cov roj txuas ntxiv ntawm cov roj taum pauv ntawm 12 - 18%, thaum txo cov tshuaj tiv thaiv li 30%. Nws yog qhov tshwj xeeb tshaj yog tias cov microcavitation generated los ntawm ultrasound tuaj yeem rhuav tshem cov qauv roj, tab sis yuav tsis ua rau muaj cov roj tseem muaj fatty acids.
    Hais txog protein prottein extraction, auted ultrasonic kev kho (20% ntxiv rau 85%, thiab cov protein dispersion (PDI) tuaj yeem nce los ntawm 15 feem pua ​​cov ntsiab lus.

    3.3 Kev Txom Nyem Cov Khoom xyaw
    Rau cov extraction ntawm alkaloids xws li vinblastine, ultrasound - Pab cov sijhawm luv luv ntawm 85 feeb, thiab nce tawm txiaj ntsig los ntawm 40%. Kev tshawb fawb ntawm cov txheej txheem tseem ceeb qhia tau tias ultrasound (40kHz) muaj qhov zoo tshaj plaws nyob rau hauv cov xwm txheej ntawm 70% ethanol concentration, 1:15 khoom - kua piv, thiab 50 ° C kub.
    Hauv kev rho tawm ntawm Terpenoid cov tebchaw, lub hauv zos siab kub thiab siab tau tsim los ntawm ultrasound yog tsim nyog rau kev ceev ntawm cov volatile cheebtsam. Ultrasonic rho tawm ntawm peppermint roj tsis tsuas yog shortens lub sijhawm los ntawm 80%, tab sis kuj tseem nce cov lus qhia menthol los ntawm 8 - 12% piv nrog chav dob.
