Diacetyl (2,3-butanedione) yog cov khoom lag luam ib txwm muaj thiab tuaj yeem pom hauv ntau cov khoom noj xws li butter, mis, cheese, smoked lossis ci nqaij, qhob cij, txiv hmab txiv ntoo, zaub, kas fes, npias, thiab cawv. Diacetyl tau muab coj los siv ua zaub mov ntxiv los ua kom muaj qab zib thiab tau raug xaiv raws li feem ntau lees paub tias muaj kev nyab xeeb (GRAS) cov tshuaj uas muaj tshuaj lom tsawg tsawg (FDA, 1980). Qhov xav tau ntau qhov qab zib hauv cov zaub mov yog kwv yees li 0.05-5.0 ppm thiab siab dua qhov ntawd nws ua rau tsis nyiam saj. Kev lees paub feem ntau siv tam sim no tau nyob hauv microwave paj kws, tab sis nws kuj tau siv rau ntau yam khoom lag luam (NTP, 1994, 2007). Diacetyl tuaj yeem siv rau hauv cov tshuaj ntxiv ua kua, muab tshuaj, lossis hmoov (Boylstein li al., 2006).

Nws ua tau raws li GB 2760-1996 tus qauv ntawm cov txuj lom noj tau rau lub sijhawm no. Nws feem ntau yog siv rau kev npaj cov khoom noj zoo ib yam li qab zib, cheese fermentation thiab kas fes ntaus yam, siv mis, butter, margarine, cheese, khoom qab zib thiab lwm yam qab, xws li txiv hmab txiv ntoo, caramel, qhob noom xim kasfes, cherry, vanilla taum, zib ntab, cocoa, txiv hmab txiv ntoo, cawv, tsw qab, rum, txiv ntoo, almonds, qhiav thiab lwm yam. Nws kuj tseem tuaj yeem siv rau hauv cov txiv hmab txiv ntoo tshiab ntxhiab tsw ntxhiab rau pleev lossis hom tshiab yam hauv kab, thiab siv los ua tus neeg sawv cev ua kua gelatin thiab tus neeg sawv cev yees duab. 2,3-Butanedione yog cov tshuaj tsw qab uas yog xim daj kom daj daj ua kua nrog muaj ntxhiab tsw ntxhiab. Nws tseem paub tias yog 2,3-butanedione thiab tau sib xyaw ua ke los ntawm methyl ethyl ketone. Nws yog miscible hauv dej, glycerin, cawv, thiab ether, thiab nyob rau hauv cov dej dilute heev nws muaj tus ntxhiab tsw ntxhiab thiab tsw.
