Inkcazo
I-Aspartame luhlobo lwe-sweeteners eyenziweyo, ye-amino acid ephuma kwi-dipeptide, yi-chemist iphuhliswe iziyobisi zezilonda ezifunyenwe ngo-1965. Ngedosi ephantsi, ubumnandi obuphezulu (ubumnandi buyi-150 ukuya ku-200 amaxesha e-sucrose), incasa elungileyo, yokwandisa incasa yesitrasi. kunye nezinye iziqhamo kunye nokunciphisa ukushisa akuvelisi i-caries yamazinyo, i-toxicity kune-saccharin kunye nezinye iingenelo ze-synthetic arhente yobumnandi, isetyenziswa ngokubanzi kwiziselo, ukutya kwesifo seswekile kunye nokunye ukutya okunempilo okuncinci, ubomi bethu bemihla ngemihla ukusela i-cola formula kanye iqulethe imveliso.
I-Aspartame kwiinkqubo ze-metabolic emzimbeni kunye neemveliso eziphambili zokuwohloka yi-phenylalanine, i-methanol kunye ne-aspartic acid, ayingeni kumjikelezo wegazi, kwaye ayiqokeleli emzimbeni, ukutya kwempilo kungenabungozi.Kodwa ngenxa yeziphene zemetabolism kwizigulane ezine-phenylketonuria (PKU), i-phenylalanine engaphezulu komzimba inokuchaphazela ukukhula kwayo, ngoko ke kwizigulana ezinesifo ukuvala ukongeza i-aspartame.
I-Aspartame iya kusombulula kwaye ilahlekelwe bubumnandi emva kokufudumeza ixesha elide kwaye izinzile kubushushu obuphantsi kwaye phantsi kwexabiso le-PH 3 ukuya ku-5, kwaye ilungele isiselo esitsha kunye nokutya ngaphandle kokufudumeza.
Umsebenzi
(1) I-Aspartame yi-oligosaccharides esebenzayo yendalo, akukho ukubola kwamazinyo, ubumnandi obucocekileyo, ukufunxa okuphantsi komswakama, akukho nto encamathelayo.
(2) I-Aspartame inencasa ecocekileyo eswiti kwaye ifana kakhulu ne-sucrose, ineswiti ehlaziyayo, ayinakrakra emva kwencasa kunye nencasa yesinyithi.
3
(4) I-Aspartame kunye nezinye i-sweeteners okanye umxube we-sucrose unempembelelo ye-synergistic, efana ne-2% ukuya kwi-3% ye-aspartame, inokufihla kakhulu incasa embi ye-saccharin.
Isicelo
I-Aspartame imalunga ne-180-200 amaxesha amnandi kune-sucrose (iswekile yetafile).Ngenxa yale propati, nangona i-aspartame ivelisa i-kilocalories ezine zamandla ngegram (17 kJ / g) xa i-metabolized, ubuninzi be-aspartame efunekayo ukuvelisa ukunambitheka okumnandi kuncinci kangangokuba igalelo layo lekhalori alinakwa.Ubumnandi be-aspartame buhlala ixesha elide kunobo be-sucrose, ke buhlala budityaniswa nezinye izimuncumuncu zokwenziwa ezifana ne-acesulfame potassium ukuvelisa incasa iyonke efana neyeswekile.
I-Aspartame isetyenziswa njenge-ejenti eswiti kakhulu kwiimveliso zesiselo, kwiimveliso zokutya, kunye ne-sweeteners engaphezulu kwetafile, nakumalungiselelo amayeza okubandakanya iipilisi, imixube yomgubo, kunye namalungiselelo evithamin.Iphucula iinkqubo zencasa kwaye ingasetyenziselwa ukufihla ezinye iimpawu ezingathandekiyo zencasa.Nangona kunjalo, ekusebenzeni, inani elincinci le-aspartame elisetyenzisiweyo libonelela ngesiphumo esincinci sezondlo.
