Aspartame yog cov khoom qab zib nrov tshaj plaws hauv Tebchaws Meskas.Nws yog muag raws li cov khoom qab zib xws li NutraSweet thiab Equal, tab sis nws kuj tau muab tso rau hauv ntau txhiab khoom noj.
Aspartame yog ib qho khoom qab zib siab uas yog dipeptide, muab 4 cal / g.Nws yog synthesized los ntawm combining methyl ester ntawm phenylalanine nrog aspartic acid, tsim cov compound nl-alpha- aspartyl-l-phenylalanine-1-methyl ester.nws yog kwv yees li 200 npaug ntawm qab zib li sucrose thiab saj zoo ib yam li qab zib.nws yog qhov sib piv sweeter nyob rau hauv qis siv theem thiab nyob rau hauv chav tsev kub.nws qhov tsawg kawg nkaus solubility yog nyob ntawm ph 5.2, nws cov ntsiab lus isoelectric.Nws qhov siab tshaj plaws solubility yog ntawm ph 2.2.Nws muaj 1% solubility hauv dej ntawm 25 ° C.solubility nce nrog kub.aspartame muaj qee yam tsis ruaj khov hauv cov kua dej uas ua rau txo qis qab zib.Nws decomposes rau aspartylphenylalanine los yog mus rau diketropiperazine (dkp) thiab tsis muaj cov ntaub ntawv no qab zib.Kev ruaj ntseg ntawm aspartame yog kev ua haujlwm ntawm lub sijhawm, qhov kub thiab txias, ph, thiab dej ua haujlwm.Qhov siab tshaj plaws stability yog kwv yees li ph 4.3.Nws tsis yog feem ntau siv rau hauv cov khoom ci vim tias nws tawg ntawm qhov kub kub.nws muaj phenylalanine, uas txwv tsis pub nws siv rau cov neeg txom nyem nrog phenylketonuria, tsis muaj peev xwm mus metabolize phenylalanine.siv xws li cov khoom noj tshais txias, khoom qab zib, cov khoom sib xyaw ua ke, zom cov pos hniav, dej haus, thiab cov khoom qab zib khov.Kev siv theem ntawm 0.01 txog 0.02%.
