Qauv Thiab Cov Khoom Ntawm Artificial Sweeteners

Saccharin, saccharin, thiab acesulfame tag nrho yog cov ntsev sulfonamide thiab yog cov khoom qab zib zoo nkauj nrog cov solubility siab. Ntawm lawv, Ansaimi muaj zog thermal stability. Nyob rau hauv acidic tej yam kev mob, acesulfame tuaj yeem ua rau me ntsis hydrolysis thiab tsim acetylacetamide.
Aspartame yog ib tug dipeptidyl methyl ester, ib tug tag nrho hluavtaws uas tsis yog carbohydrate dag sweetener. Tsis zoo li acesulfame, aspartame muaj thermal instability thiab yuav degrade thaum khaws cia rau hauv kua rau ntev. Nyob rau hauv acidic los yog alkaline tej yam kev mob, aspartame hydrolyzes tsim methanol thiab amino acids. Aspartame yog qhov ruaj khov tshaj plaws ntawm pH 4.3.
Cov qauv ntawm neotame zoo ib yam li aspartame, thiab nws yog ib qho derivative ntawm dipeptide tebchaw nrog muaj zog thermal stability.
Sucralose yog polar chlorinated qab zib uas muaj tsib pawg hydroxyl thiab peb chlorine atoms. Nws yog tsim los ntawm kev xaiv hloov peb pawg hydroxyl ntawm sucrose nrog chlorine atoms. Sucralose muaj dej solubility siab, muaj zog thermal stability, thiab acid thiab alkali tsis kam.
NHDC yog tau los ntawm alkaline hydrogenation ntawm flavonoids pom nyob rau hauv citrus txiv hmab txiv ntoo. Nws tsis yooj yim hydrolyzed nyob rau hauv acidic tej yam kev mob thiab muaj zog thermal stability. Tsis tas li ntawd, nws cov khoom antioxidant tau raug pov thawj.
