Siv:

-Food additive: Vim nws cov khoom qab zib tshwj xeeb, nws yog siv los ua cov khoom noj khoom haus, tshwj xeeb tshaj yog cov khoom qab zib, jam thiab khoom qab zib.

-Spices: tuaj yeem siv los ua cov khoom noj kom muab zaub mov ib qho tsw.

-perfume kev lag luam: ua ib qho ntawm cov khoom xyaw ntawm naj hoom essence.

Txoj kev:

(5h) furanone tuaj yeem npaj tau los ntawm cov kauj ruam hauv qab no:

1. Nrog 3-methyl -2-pentanone raws li cov khoom pib, 3-hydroxy -4-methyl -2-pentanone tau txais los ntawm keto-alcohol cov tshuaj tiv thaiv.

2.3-hydroxy -4-methyl -2-pentanone yog reacted nrog tus neeg sawv cev etherifying (xws li diethyl ether) los tsim cov khoom lag luam etherification.

3. Cov khoom lag luam etherification raug rau acid catalysis thiab deoxidation cov tshuaj tiv thaiv kom tau furanone (5h).

Cov ntaub ntawv kev nyab xeeb:

-(5h) furanone raug suav hais tias muaj kev nyab xeeb rau kev siv dav dav, tab sis tej zaum yuav ua rau khaus ntawm daim tawv nqaij thiab ob lub qhov muag ntawm qhov siab.

-Siv yuav tsum tau xyuam xim rau kev tiv thaiv kev tiv thaiv, tsis txhob sib cuag nrog daim tawv nqaij thiab ob lub qhov muag, thiab tuav lub qhov cua kom zoo.

- Ua raws li cov txheej txheem kev nyab xeeb thaum siv, thiab khaws cia rau hauv qhov chaw qhuav, txias, deb ntawm hluav taws thiab oxidizing cov neeg ua haujlwm.
