Taw qhia

Vanillin, tshuaj hu ua vanillin, yog ib qho organic compound nrog ib tug tshwj xeeb aroma thiab saj.

 

Muaj ntau txoj hauv kev los ua vanillin. Txoj kev siv feem ntau yog muab rho tawm los yog ua los ntawm ntuj vanilla. Ntuj vanilla extracts muaj xws li nyom resin rho tawm los ntawm vanilla taum pods thiab ntoo vanillin muab rho tawm los ntawm ntoo. Cov txheej txheem synthesis yog siv cov phenol nyoos los ntawm cov tshuaj phenolic condensation los tsim vanillin.

Vanillin yog cov khoom siv hluav taws xob thiab yuav tsum tau khaws cia kom deb ntawm cov nplaim taws thiab qhov kub thiab txias. Hnav cov hnab looj tes tiv thaiv thiab tsom iav thaum ua haujlwm kom tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag. Kev nqus pa ntawm nws cov plua plav lossis vapors yuav tsum tau zam thiab kev ua haujlwm yuav tsum tau ua nyob rau hauv qhov chaw zoo. Vanillin feem ntau suav hais tias yog cov tshuaj muaj txiaj ntsig zoo uas tsis ua rau muaj kev phom sij ntau dua rau tib neeg thaum siv thiab khaws cia kom raug. Txawm li cas los xij, rau qee tus neeg uas muaj kev fab tshuaj, qhov ntev ntev los yog loj ntawm vanillin tuaj yeem ua rau muaj kev tsis haum tshuaj thiab yuav tsum tau siv ceev faj.
