Kev sib piv ntawm cov roj teeb tseem ceeb: kev nruj me ntsis vs. supercritical extraction
Cov hau kev siv rau cov roj tseem ceeb rho tawm cuam tshuam nrog kev ua raws li lawv txoj kev nyab xeeb, kev nyab xeeb, thiab cov ntawv thov. Ntawm cov txheej txheem ntau ntxiv, cov kuab tshuaj rho tawm thiab cov kev rho tawm supercritical tau siv yog cov feem ntau dav siv.
1. Cov kev sib tw tawm
⑴PrIn tshaj tawm
Organic cov kuab tshuaj (piv txwv li, hexane, ethanol) yaj cov ntxhiab tsw qab ntawm cov khoom siv cog. Txoj kev daws teeb meem yog li evaporated thiab sib cais kom tau txais qhov tseeb (ib tug muaj ntxhiab tsw ntxhiab extract).
⑵KEKE Kauj Ruam:
①dissolution: Cov khoom cog ntoo yog raus hauv ib cov kuab tshuaj, uas precipitates tseem ceeb roj thiab ua pob zeb ua (ib waxy cov pob zeb sib xyaw).
②purification: zaum ob tshem tawm nrog dej cawv tshem tawm impurities, ua raws los ntawm evaporation kom yieldrated meej.
New Shaadvantages
①preserves tag nrho aroma: tsawg {{- kev ua haujlwm kub ua rau nws zoo tshaj plaws rau cov khoom siv kub thiab txias, tiv thaiv kev puas tsuaj kub.

⑷disadvantages
① Yuav muaj kev pheej hmoo ntawm cov kuab tshuaj: txawm tias tom qab muaj kev huv huv, kab lus (~ 1%) ntawm cov kuab tshuaj organic yuav nyob rau hauv, tshaj tawm cov kev pheej hmoo muaj kev phom sij.
Tsis tsim nyog rau qhov ncauj siv: Cov kuab tshuaj uas muaj kev cuam tshuam yuav muaj kev phom sij, txwv nws daim ntawv thov rau sab nraud khoom.
⑸Appllicable scenarios
①floral cov roj tseem ceeb: Rose tshem tawm, neroli, jasmine, thiab lwm yam.
Cov ntaub ntawv: khoom aratics xws li Benzoin thiab FrankCensense.
2. Cov kua dej supercritical rho tawm ('supcritical sib txuas tau)
⑴PrIn tshaj tawm
Siv supercritical carbon dioxide (kub thiab siab) raws li cov kuab tshuaj rau kev xaiv tshem tawm cov hom phiaj. Cov roj tseem ceeb yog tom qab sib cais ntawm lub siab txo.
⑵key tsis tau:
①Critical taw tes: Kev sib koom ua kua ntawm 31.1 Degree thiab kev sib txuas nrog roj nrog kua {{3} zoo li solubility.
Ofactional ②Freaction tawm tswv yim: kev kho kom haum thiab ntsuas kub thiab ntsuas kom meej rau tshwj xeeb cov cheebtsam (piv txwv li, cais tawm terpenes los ntawm waxes).
New Shaadvantages
① XOOM XYUAS NYOB: CO₂ tsis yog - pakic thiab tag nrho evaporates, kom siab, ua kom muaj siab,}}} kev purity khoom.
② Tsawg -} kub ceev cia: Tiv thaiv cov cua sov -, polyphenols hauv cov roj pomegranate noob).
③hu Xaiv: Cov khoom xyaw tshwj xeeb (piv txwv li cov tshuaj yej polyphenols los ntawm cov noob ntoo).
⑷disadvantages
① Cov nqi khoom siv siab: Cov cuab yeej siv hluav taws xob yog kim thiab thev naus laus zis.
② Txwv tsis pub muaj peev xwm ntau lawm: zoo tshaj plaws rau high - muaj txiaj ntsig tseem ceeb roj; Loj - teev nyiaj txiag kev lag luam yuav tsum tau ua opecics.
⑸Appllicable scenarios
①premium ua haujlwm rau roj: Frankincense, MyRrh, hiav txwv buckthorn noob noob roj, thiab lwm yam.
②food / kws tshuaj paus - qib kev rho tawm: curcumin, dog dig, thiab lwm yam.
Yuav xaiv li cas?
Cov kuab tshuaj yeeb yaj kiab tawm: zoo tshaj plaws rau tsawg -}}}}}}} note}:: Cov kuab tshuaj: cov kuab tshuaj).
Supercritical extraction: eco - Tus phooj ywg thiab meej, zoo tagnrho rau high- Cov nqi sib puractions (siab dua upfront tus nqi).
