Taw qhiathiab daim ntawv thovntawm CAS 14667-55-1|Trimethyl-pyrazine
2,3,5-Trimethylpyrazine yog ib qho tsis haum tshuaj organic uas yog siv los ua ib qho tshuaj tsw qab los muab cov kas fes ci. Nws tau pom tias yog synthesized los ntawm cov tshuaj tiv thaiv ntawm trimethyl thiab pyruvic acid nyob rau hauv ib tug enzymatic cov tshuaj tiv thaiv siv glutamate pyruvate transaminase.
2,3,5-Trimethylpyrazine tuaj yeem soj ntsuam los ntawm capillary gas chromatography nrog huab hwm coj spectrometric detection (GC-MS) los yog ua haujlwm siab ua kua chromatography nrog loj spectrometric detection (HPLC-MS). Qhov sib xyaw no kuj tuaj yeem txheeb xyuas los ntawm nws cov synchronous fluorescence emission spectrum.
Kev tshuaj xyuas ntawm cov khoom siv tshuaj lom neeg no tau nthuav tawm ib pawg hydroxyl ntawm pawg methyl thiab protocatechuic acid moiety ntawm lub nplhaib pyrazine. Lub xub ntiag ntawm cov pab pawg ua haujlwm no muab pov thawj rau cov qauv qauv uas tau thov rau cov qauv no.
Daim ntawv thov:
Raws li cov khoom ci, cheese, nqaij, luam yeeb.
Feem ntau yog siv los npaj flavors xws li cocoa, chocolate thiab roasted ceev.
Siv rau flavoring flavors nyob rau hauv cov khoom ci xws li cocoa, kas fes, roasted peanuts, thiab lwm yam.
Synonyms:
Trimethyl-pyrazine;
2,3, 5-trimethylpyrazine;
Pyrazine, trimethyl-;
