Dab tsi yog qhov txawv ntawm kev ua cov kauj ruam ntawm supercritical extraction ntawm tshuaj yej polyphenols thiab decaffeination hauv tshuaj yej ntsuab?
Lub ntsiab sib txawv ntawm supercritical carbon dioxide (SC-CO2) extraction ntawm tshuaj yej polyphenols los ntawm ntsuab tshuaj yej thiab decaffeination nyob rau hauv cov nqe lus ntawm kev ua cov kauj ruam yog raws li nram no:
Tshuaj yej polyphenols & decaffeination
Cov kauj ruam kho ua ntej
- **Tea polyphenol extraction**: ntsuab tshuaj yej feem ntau yuav tsum tau qhuav thiab crushed thiaj li yuav ua rau kom cov huab cua permeability ntawm cov tshuaj yej nplooj kom SC-CO2 tau zoo sib cuag nrog cov tshuaj yej nplooj.
- **Decaffeination**: Nyob rau hauv cov txheej txheem decaffeination, tshuaj yej nplooj yuav tsum tau infiltrated nrog ethanol tov tsis pub tshaj 70% rau 1-4 teev raws li cov kauj ruam ua ntej kho, ntxiv rau kom qhuav thiab crushing.
Extraction tej yam kev mob
- **Tea polyphenol extraction**: txheej txheem tej yam kev mob xws li siab, kub, lub sij hawm, thiab hom thiab tus nqi ntawm entrainer yog optimized los ntawm ib-txoj kev thiab orthogonal xeem. Piv txwv li, qhov zoo tshaj plaws tej yam kev mob tej zaum yuav siab 35 MPa, kettle kub 50 degree, static extraction lub sij hawm 1 teev, thiab dynamic extraction lub sij hawm 1 teev.
- ** Kev tshem tawm Caffeine **: Cov txheej txheem zoo tshaj plaws yuav suav nrog qhov ntsuas kub ntawm 60 degree, qhov siab ntawm 28 MPa, lub sijhawm rho tawm ntawm 3.5 teev, thiab dej ntxiv ntawm 20%.
Kev kho mob tom qab rho tawm
- **Tea polyphenol extraction**: cov tshuaj yej extracted polyphenols yuav tsum tau yooj yim nqus freeze-drying kom tau cov tshuaj yej polyphenol cov khoom uas muaj cov ntsiab lus siab ntawm meso-catechins.
- ** Caffeine tshem tawm **: CO2 nrog caffeine raug xa mus rau lub tank ntxuav kom hloov cov caffeine mus rau theem aqueous, ces cov caffeine tau zoo los ntawm distillation thiab CO2 rov ua dua.
Lub Hom Phiaj Cheeb Tsam
- **Tea polyphenol extraction**: lub hom phiaj yog kom rho tawm cov tshuaj yej polyphenols, yog li qhov optimization ntawm cov txheej txheem tsis tsuas yog revolves nyob ib ncig ntawm nce tus nqi extraction ntawm tshuaj yej polyphenols.
- ** Caffeine tshem tawm **: lub hom phiaj yog tshem tawm caffeine, yog li cov txheej txheem parameter optimization feem ntau revolves nyob ib ncig ntawm kev txhim kho cov caffeine tshem tawm tus nqi.
- Ob txoj kev raug suav tias yog ib puag ncig zoo thiab nyab xeeb vim tias lawv tsis koom nrog kev siv tshuaj lom neeg thiab CO2 tuaj yeem rov ua dua.
Cov kev sib txawv no qhia txog lub hom phiaj sib txawv thiab kev ua kom zoo tshaj plaws ntawm ob txoj kev rho tawm, nrog rau kev txiav txim siab ntawm cov khoom siv physico-chemical ntawm cov khoom sib txawv.
