Thawj qhov tsw qab, vanillin, tau tsim nyob rau xyoo 1874 los ntawm German kws tshawb fawb M. Harman thiab G. Dr. Twyman. Nws feem ntau yog cais ua methyl thiab ethyl vanillin.

1. Methyl vanillin: crystalline dawb los yog daj me ntsis nrog ib tug nplua nuj mis nyuj tsw thiab ib tug vanilla aroma; ib qho ntawm cov khoom siv dav siv hauv cov tshuaj tsw qab; qhov tseem ceeb ntawm txhua tus neeg nyiam creamy vanilla tsw. Nws yog dav siv nyob rau hauv ntau yam lag luam, nrog rau kev ua noj ua haus, tshuaj, thiab luam yeeb industries ua txuj lom, flavoring agents, los yog tsw enhancers, uas yog feem ntau siv nyob rau hauv dej qab zib, candies, ncuav mog qab zib, biscuits, qhob cij, thiab roasted noob. Tsis muaj ntawv ceeb toom hais tias vanillin yog tshuaj lom rau tib neeg.


2. Ethyl vanillin: crystalline hmoov los yog dawb mus rau me me daj koob siv lead ua muaj zog aroma tshaj methyl vanillin, zoo li vanilla taum. Ib qho ntawm cov txuj lom tseem ceeb tshaj plaws nyob rau hauv lub ntiaj teb no, broad-spectrum flavors yog ib qho tseem ceeb thiab tsim nyog raw khoom rau kev lag luam khoom noj khoom haus additives. Cov tshuaj tsw qab ntev ntev thiab cov tshuaj tsw qab ntawm cov taum vanilla ua rau nws tsw qab peb mus rau plaub npaug zog dua li vanillin. Aroma thiab tsw yog nquag siv hauv chocolate, ice cream, dej qab zib, thiab tshuaj pleev ib ce.

Tsis tas li ntawd, ethyl vanillin yog siv los ua ib qho ntxiv hauv kev pub, ua tus neeg sawv cev ci ntsa iab hauv electroplating, thiab ua tus neeg nruab nrab hauv kev lag luam tshuaj. C. Glyoxylate txoj hauv kev hauv Guaiacol Vanillin yog tsim los ntawm kev siv glyoxylic acid thiab guaiacol ua raw khoom, ua raws li condensation, oxidation, thiab decarboxylation. Txoj hauv kev no feem ntau yog tsim los ntawm Fab Kis Rhone-Poulenc corporation tshawb fawb thiab kev tsim kho, thiab kev tsim khoom loj. Ob txheej txheej ozone decomposition tau siv los tsim glyoxylic acid los ntawm cov txiv neej acid methyl ester (German patent 3224795). Qhov zoo ntawm kev siv hluavtaws yog nws cov khoom siv dav dav, cov kauj ruam ntawm cov tshuaj tiv thaiv tsawg dua, tus nqi qis, thiab txo cov pa phem los ntawm peb qhov pov tseg. Nws raug suav hais tias yog txoj hauv kev tsim nyog tshaj plaws raws li qhov tshwm sim.
