Lub superiority ntawm supercritical CO2 kua extraction technology nyob rau hauv modernization ntawm tsoos suav tshuaj. Piv nrog rau cov txheej txheem ntawm cov tshuaj suav tshuaj, kev siv cov thev naus laus zis CO2 extraction technology rau kev tshawb fawb, kev tsim kho, thiab kev tsim kho ntawm cov tshuaj suav tshuaj muaj ntau yam zoo.
1. Muaj peev xwm extraction muaj zog thiab siab extraction npaum li cas. Extracting cov khoom xyaw zoo los ntawm cov tshuaj suav tshuaj siv supercritical CO2 tuaj yeem yuav luag tag nrho cov khoom xyaw raws li cov txheej txheem zoo, txhim kho cov khoom lag luam tawm los thiab kev siv peev txheej. Lub caij no, nrog kev nce qib ntawm supercritical CO2 extraction technology thiab daim ntawv thov ntawm perfluoropolyether ammonium carbonate (PFPE), supercritical CO2 extraction tau txuas mus rau aqueous tov systems, ua rau nws muaj peev xwm mus rho tawm cov polar tebchaw xws li cov proteins uas nyuaj rau extract.
2. Lub peev xwm extraction nyob ntawm qhov ntom ntawm cov kua thiab qhov kawg ntawm qhov kub thiab txias. Hloov ib lossis ob qho tib si tuaj yeem hloov pauv cov solubility thiab xaiv cais ntau yam tshuaj hauv cov tshuaj suav tshuaj, yog li txo cov impurities thiab ua kom cov khoom xyaw nquag ntawm cov tshuaj suav tshuaj. Ib qho yooj yim los txo cov koob tshuaj thiab kev tswj kom zoo, zoo heev txhim kho cov khoom zoo li.
3. Supercritical CO2 muaj qhov kub thiab txias tsis tshua muaj kev khiav hauj lwm, uas tuaj yeem khaws cov khoom xyaw tseem ceeb ntawm cov tshuaj suav tshuaj tsis raug puas tsuaj thiab tsis muaj cov tshuaj tiv thaiv biochemical. Yog li ntawd, nws yog tshwj xeeb tshaj yog haum rau extracting Cheebtsam uas yog heev rhiab heev rau tshav kub thiab yog nquag oxidative decomposition thiab puas.
4. Lub sij hawm rho tawm sai thiab lub voj voog luv luv. Thaum pib ntawm lub supercritical CO2 extraction (dynamic) voj voog, kev sib cais pib. Feem ntau, cov khoom sib cais thiab sib cais tom qab 10 feeb ntawm kev rho tawm, thiab tuaj yeem muab rho tawm tag nrho hauv li 2-4 teev. Nyob rau tib lub sijhawm, nws tsis tas yuav tsum muaj cov kauj ruam concentration, thiab txawm tias nrog kev sib ntxiv ntawm entrainer, nws tuaj yeem raug tshem tawm los ntawm kev sib cais los yog yooj yim concentrated.
5. Supercritical CO2 extraction, nrog kev tswj tau yooj yim ntawm kev khiav hauj lwm tsis, xyuas kom ruaj khov cov khoom xyaw thiab cov khoom zoo.
6. Supercritical CO2 tseem tuaj yeem ncaj qha rho tawm qhov sib txawv lossis cov khoom rho tawm los ntawm ib leeg lossis cov tshuaj suav tshuaj suav tshuaj rau kev tshuaj xyuas tshuaj, tsim cov tshuaj tshiab, thiab txhim kho qhov nrawm ntawm kev tshuaj ntsuam tshuaj tshiab. Nyob rau tib lub sijhawm, nws tuaj yeem tshem tawm ntau yam tshuaj uas tsis tuaj yeem muab rho tawm los ntawm cov txheej txheem ib txwm siv, thiab nws yooj yim dua los nrhiav cov khoom tshiab los ntawm cov tshuaj suav tshuaj, yog li nrhiav tau cov tshuaj tshiab thiab tsim cov tshuaj tshiab.
7. Supercritical CO2 kuj muaj cov tshuaj tua kab mob antioxidant thiab ua kom tsis muaj menyuam, uas muaj txiaj ntsig zoo rau kev ua kom ntseeg tau thiab txhim kho cov khoom zoo.
8. Supercritical kua extraction tau dhau los ua ib txoj hauv kev zoo rau kev tsom xam lossis ua ke nrog GC, IR, MS, LC, thiab lwm yam. .
9. Nws tau raug pov thawj los ntawm kws tshuaj thiab kev soj ntsuam kev coj ua uas supercritical CO2 extraction ntawm cov tshuaj suav tshuaj tsis yog tsuas yog thev naus laus zis zoo tshaj, tab sis kuj muaj kev ruaj ntseg zoo thiab tswj tau yooj yim. Nws cov tshuaj pharmacological thiab kev kho mob tuaj yeem lav lossis zoo dua.
10. Cov txheej txheem supercritical CO2 extraction muaj cov txheej txheem yooj yim, kev ua haujlwm yooj yim, txuag kev ua haujlwm thiab cov kuab tshuaj organic ntau, thiab txo cov pa phem ntawm peb cov khib nyiab. Qhov no undoubtedly muab ib tug high-tech tshiab txoj kev rau modernization ntawm tsoos suav tshuaj extraction, sib cais, npaj, thiab concentration.
