Usawoti ohlukahlukene we-glutamic acid, osebenza njengezithuthukisi ukunambitheka, ubizwa ngokuthi i-glutamate. I-Glutamic acid ngokwemvelo itholakala ekudleni okuningi, njengotamatisi, i-parmesan, nenhlanzi. Ngendlela eboshwe ngayo, ayinalo ithonya kumqondo womuntu wokunambitha. Njengoba ikhiqizwa futhi kumetabolism yomuntu, ingasetshenziswa ngokuphelele ngumzimba.
I-Glutamates ne-glutamic acid ingasetshenziswa njengezithasiselo zokudla ukuze kukhishwe ukunambitheka okumnandi - okubizwa ngokuthi umami. Lezi zengezo (E620 kuya ku-E625) zifaka, isibonelo, i-glutamic acid ehlanzekile (E 620), i-monosodium glutamate (E 621), noma i-magnesium diglutamate (E 625). Kodwa-ke, i-glutamate nayo ingafihlwa ngemuva kwemibandela yesinongo, i-yeast extract, noma amaphunga kuhlu lwezithako. Isithuthukisi se-flavour ngokwemvelo siqukethwe ku-yeast extract, isibonelo, ngakho-ke akudingeki ukuthi sibhalwe njengesithasiselo.
Nakuba i-glutamate ngokuvamile ibhekwa njengengenampilo, lokhu akukakafakazelwa ngokwesayensi. Ngamanani ajwayelekile, ihlukaniswa njengengenabungozi, ikakhulukazi njengoba ivame ukumuncwa ukudla okusesimweni sayo semvelo ngaphandle kokudala izimpawu.
I-glutamate kuthiwa iqala lokho okubizwa ngokuthi yi-Chinese restaurant syndrome. Ngemva kokudla ukudla okune-glutamate, okuvame ezindaweni zokudlela zase-Asia, labo abathintekile bakhononda ngekhanda elibuhlungu nobuhlungu bomzimba, isicanucanu, nokuba ndikindiki entanyeni. Nokho, lokhu akukaze kufakazelwe ezifundweni. Kungacatshangwa ukuthi ezinye izimo noma uhlobo oluthile lomphumela ongemuhle we-placebo obangele lezi zimpawu. Ngaphezu kwalokho, i-glutamate kwakusolwa ukuthi ikhuthaza izifo zesimiso sezinzwa esiphakathi, okungakaqinisekiswa futhi.
Okokugcina, kunamahemuhemu okuthi i-glutamate ivuselela isifiso sokudla futhi ngaleyo ndlela ibangele ukukhuluphala. Nakuba lokhu kungase kufakazelwe ekuhlolweni kwezilwane, iqiniso lokuthi isithuthukisi ukunambitheka sinomthelela ofanayo kubantu nalo alikaqinisekiswa kuze kube manje.
Ngokolwazi lwamanje lwesayensi, i-glutamate ngokwayo ayibonakali ingenampilo. Kodwa-ke, isithuthukisi sokunambitha sivame ukusetshenziswa ekudleni okulungile okuqukethe amafutha amaningi kanye/noma ushukela. Ngaphezu kwalokho, i-glutamate ivame ukusebenzela inhloso yokwenza ukuntuleka kwamakhambi amasha, izinongo, nezinye izithako ezibizayo, ezisezingeni eliphezulu ngokunambitha. Ukudla okunjalo akukona okungenampilo ngokulinganisela, kodwa ukusetshenziswa njalo noma ngokweqile kungaholela ekuntulekeni kwezakhi ezithile kanye nokukhuluphala ngokuhamba kwesikhathi. Nokho, lokhu akubangelwa yi-glutamate.
Kodwa-ke, abantu abadla ukudla okulinganiselayo nokunempilo jikelele futhi badle izithelo nemifino eminingi emisha ngezikhathi ezithile bangadla isidlo esilungile nge-glutamate noma ezinye izithuthukisi zokunambitheka ngaphandle konembeza onecala.
