Nws yog tsis yooj yim sua kom rho tawm cov aromatic yam ntawm vanilla taum ntawm ib tug neeg kho tshuab los yog distillation txheej txheem. Hloov chaw, vanilla yog muab rho tawm los ntawm cov taum siv sib tov ntawm cawv (feem ntau ethyl) thiab dej.
Tab sis ua ntej qhov no tuaj yeem ua tiav, cov pods uas muaj cov taum vanilla yuav tsum tau ua cov txheej txheem kho uas yuav siv sijhawm li 3 - 4 lub hlis kom tiav. Qhov no tso cai rau kev nthuav tawm ntau dua ntawm vanillin, cov organic compound lub luag haujlwm rau vanilla's iconic aroma.
Tom qab kho tiav, cov txheej txheem ntawm kev rho tawm yuav mus rau lub hlis ua ntej qhov sib tov muaj hnub nyoog txaus kom tau kos tawm qhov txawv vanilla aroma. Yuav kom ua tiav qhov kev pom zoo tshaj plaws ntawm vanillin extraction, vanilla pods yuav tsum tau zaum hauv cov dej sib tov no rau ntau lub hlis.
Tab sis kom ua tiav lub sijhawm hloov pauv, koj xav tau lub peev xwm los ua kom ib puag ncig ib puag ncig nyob rau hauv txoj kev uas tsuas yog cov tuam txhab loj loj tuaj yeem ua tau.

Vanilla oleoresin
Thaum vanilla oleoresin tsis yog cov roj tseem ceeb, nws feem ntau siv los ua ib qho. Vanilla oleoresin yog tsim los ntawm kev tshem tawm cov kuab tshuaj los ntawm vanilla extract. Nws yog tuab dua li cov roj yam tseem ceeb thiab yog qhov kev xaiv pheej yig dua uas feem ntau ntxiv rau cov khoom tu tus kheej.
Vanilla roj infusion
Cov txheej txheem no suav nrog kev ntub dej qhuav, fermented vanilla taum nrog cov roj nruab nrab xws li cov roj txiv hmab txiv ntoo lossis roj almond uas zoo meej rau kev rho tawm cov yam ntxwv ntawm vanilla. Cov txheej txheem ntawm fermentation thiab ziab kom qhuav tsim cov enzymes ntuj uas muaj lub luag haujlwm rau cov nplua nuj tsw thiab aroma ntawm vanillin.
Muaj ob qhov zoo heev ntawm vanilla roj infusion uas paub qhov txawv ntawm vanilla extract.

Vanilla extract, ntawm qhov tod tes, yuav tsum tsuas yog siv rau deodorizing, khoom zoo nkauj thiab ua noj. Qhov thib ob, vanilla roj infusion tuaj yeem ua tau yooj yim hauv tsev thiab siv sijhawm tsawg dua los tsim.
Txhawm rau ua koj tus kheej cov roj vanilla infusion, koj tuaj yeem pib los ntawm kev tau txais qee cov taum vanilla thiab hlais rau hauv me me. Tom qab ntawd koj muab cov khoom no tso rau hauv ib lub thawv thiab sau nws nrog koj nyiam nruab nrab roj. Tom qab ntawd, koj tuaj yeem pop lub hau ntawm lub thawv thiab cia cov sib tov sib xyaw rau li peb lub lis piam (qhov ntev dua qhov zoo dua). Tom qab nws tau infused, koj muaj peev xwm ncuav cov tshuaj los ntawm ib tug sieve thiab mus rau hauv ib tug tshiab hub.
Lub resulting roj infusion tuaj yeem siv rau ntau daim ntawv thov. Ntxiv rau cov khoom zoo nkauj, cov roj yuav muab koj cov khoom siv hauv tsev ua kom zoo nkauj vanilla tsw. Ib zaug ntxiv, yog tias koj tab tom nrhiav vanilla tseem ceeb roj rau kev tu tawv nqaij, qhov no yog qhov koj yuav tsum siv. Koj tseem tuaj yeem siv txoj hauv kev los tsim cov roj vanillin da dej, thiab qhov no yog txoj hauv kev zoo tshaj plaws los ua kom koj lub sijhawm da dej ntau dua.
Vanilla kiag li
Txawm hais tias tsis yog qhov no lossis ib qho ntawm cov saum toj no hom ntawm vanilla derivatives haum daim nqi raws li cov roj tseem ceeb ntawm lawv tus kheej, vanilla absolute yog qhov ze tshaj plaws rau nws. Cov roj yam tseem ceeb yuav raug tsim los ntawm chav distillation, whereas vanilla absolute yuav tsum tau siv cov kuab tshuaj hloov.
Cov txheej txheem tshem tawm cov kuab tshuaj yog txheej txheem ob-kauj ruam thawj zaug uas yuav tsum tau siv cov kuab tshuaj uas tsis yog-polar kom rho tawm vanilla oleoresin los ntawm vanilla extract. Ib qho ntawm cov kuab tshuaj feem ntau siv thaum lub sijhawm no yog benzene. Tom qab ntawd, ib qho hnyav hnyav yuav raug siv los rho tawm vanilla kiag li los ntawm vanilla oleoresin. Qhov no feem ntau yuav koom nrog kev siv ethanol.
Vanilla absolute yog incredibly haib thiab yeej tsis noj. Koj tseem yuav tsis pom cov roj vanilla no hauv cov khoom siv tawv nqaij. Es tsis txhob, koj yuav pom vanilla kiag li siv nyob rau hauv perfumes. Nws lub luag haujlwm tseem ceeb hauv perfumery yog qhov ua si lub luag haujlwm ntawm cov ntawv sau.

Carbon dioxide vanilla extract
Tsis zoo li cov khoom lag luam vanilla tau hais tseg, qhov no yog cov roj tseem ceeb tiag tiag. Nws tau muab rho tawm los ntawm daim ntawv thov kev kub siab CO₂ ua cov kuab tshuaj. Dab tsi ua rau cov pa roj carbon dioxide ua cov kuab tshuaj muaj txiaj ntsig yog qhov tseeb tias nws tuaj yeem raug tshem tawm tag nrho los ntawm kev sib tov thaum extraction tiav los ntawm kev xa rov qab mus rau nws daim ntawv gaseous.
CO₂ vanilla extract yog tsim los ntawm compressing vanilla pods nrog carbon dioxide nyob rau hauv ib lub thawv stainless hlau. Cov pa roj carbon dioxide nkag mus rau hauv lub thawv yuav dhau los ua lub zog thiab tig mus ua kua. Nyob rau hauv lub xeev no, cov pa roj carbon dioxide muaj peev xwm rho tawm cov roj nyob rau hauv lub vanilla pods. Tom qab ntawd lub thawv tuaj yeem depressurized thiab rov qab mus rau nws daim ntawv gaseous. Dab tsi koj tshuav nrog yog ib qho tsis txaus ntseeg muaj zog vanilla tseem ceeb roj.
