Aspartameyog ib qho khoom qab zib uas tsis yog khoom noj khoom haus. Sweetener yog ib qho tseem ceeb ntawm cov khoom noj khoom haus ntxiv, uas muab cov khoom qab zib rau cov zaub mov, txhim kho cov zaub mov saj thiab txhim kho cov zaub mov zoo.
Aspartame muab cov khoom qab zib rau cov khoom noj; nws kuj tseem siv tau los ua ib qho tsw enhancer. Tus nqi calorific ntawm aspartame tsuas yog 4186 kJ / kg, uas yog 1/200 ntawm sucrose. Nws muaj lub zog qab zib. Qhov qab zib ntawm nws cov tshuaj dilute yog li ntawm 100 mus rau 200 npaug ntawm sucrose. Solubility hauv dej yog kwv yees li 1 feem pua thiab solubility hauv ethanol yog 0.26 mg / dL. Nws ruaj khov heev ntawm chav tsev kub thiab tsis muaj zog acid (pH 3 ~ 5), thiab yuav decompose nyob rau hauv lub sij hawm ntev kub thiab muaj zog alkali tej yam kev mob.
Tom qab aspartame nkag mus rau tib neeg lub cev ntawm qhov ncauj, peb hom metabolites ntawm aspartic acid, phenylalanine thiab methanol yog tsim nyob rau hauv qhov kev txiav txim ntawm plab hnyuv esterase thiab peptidase. Nws cov khoom lag luam amino acid tuaj yeem koom nrog cov amino acid metabolism. Methanol qib qis heev thiab metabolized sai heev nyob rau lub sijhawm no, feem ntau tsis tshua pom pom hauv cov ntshav tom qab noj aspartame.
Aspartame tuaj yeem siv dav hauv mis nyuj, jam, ncuav mog qab zib, condiments, dej haus, jelly, puffed zaub mov thiab lwm yam khoom noj siv mis.
