Insimbi engagqwali esezingeni lokudla iyinto ebalulekile ekukhiqizweni kwezinto zasekhishini, izitsha, kanye nemishini yokucubungula ukudla. Ukuqonda amazinga achaza insimbi engagqwali esezingeni lokudla kubalulekile ekuqinisekiseni ukuphepha kanye nekhwalithi yemikhiqizo ehlobene nokudla.
Inqubo eyinhloko yokubiza insimbi engagqwali njenge-food-grade isekubunjweni kwayo. Insimbi engagqwali ye-food-grade kumele ibe ne-alloys ethile ehambisana nezindinganiso zomhlaba wonke. Izinhlobo ezivame kakhulu zifaka phakathi u-304, u-316, no-430, kanti u-304 uthandwa kakhulu ngenxa yokumelana nokugqwala nokuqina kwayo.
Esinye isici esibalulekile sensimbi engagqwali esezingeni lokudla ukumelana kwayo nokugqwala nokugqwala. Lokhu kuqinisekisa ukuthi izinto azihlangani nokudla okune-asidi noma okune-alkaline, okuvimbela ukungena kwezinto eziyingozi ekudleni. Okuqukethwe kwe-chromium ensimbi engagqwali kwakha ungqimba oluvikelayo, okwandisa ukumelana kwayo nokugqwala futhi kuyenze ifaneleke ukuthintana nokudla.
Ukushelela kanye nenhlanzeko kuyizinto ezibaluleke ngokulinganayo endinganisweni yensimbi engagqwali esezingeni lokudla. Ukuphela kobuso bensimbi engagqwali kumele kube bushelelezi futhi kungabi namaphutha angaba namagciwane. Lokhu kwenza kube lula ukuhlanza nokugcina inhlanzeko yemishini yokucubungula ukudla nezitsha, kuqinisekiswe ukuthi akukho ukungcola okuphazamisa ukuphepha kokudla.
Ukungabikho kwezinto eziyingozi kungenye indlela ebalulekile. Insimbi engagqwali esezingeni lokudla akufanele ibe nezinto ezifana nomthofu, i-cadmium, noma ezinye izinto ezinobuthi ezingaba yingozi empilweni uma zithintana nokudla. Kunezinqubo zokuhlola nokuqinisekisa eziqinile ukuqinisekisa ukuthi insimbi engagqwali iyahlangabezana nalezi zindinganiso zokuphepha.
Imboni iphinde igcizelele ukubaluleka kokuthobela izinhlangano ezilawulayo ezifana ne-Food and Drug Administration (FDA) e-United States kanye nezinhlangano ezifanayo emhlabeni jikelele. Ukunamathela kule mithetho kuqinisekisa ukuthi imikhiqizo yensimbi engagqwali yezinga lokudla ihlangabezana nezindinganiso zokuphepha eziphezulu kakhulu kanye nekhwalithi.
Ekuphetheni, izindinganiso zensimbi engagqwali yezinga lokudla zigxile ezintweni ezithile, ukumelana nokugqwala, izindawo ezibushelelezi, kanye nokungabikho kwezinto eziyingozi. Ngokulandela lezi zindinganiso, abakhiqizi bangakhiqiza izinto zasekhishini nemishini engagcini nje ngokuba eqinile kodwa futhi ephephile ekuthinteni ukudla, okunikeza abathengi ukuzethemba kokuthi amathuluzi abo okupheka ahlangabezana nezindinganiso zekhwalithi eziqinile.
Isitofu sethu sensimbi engagqwali asigcini nje ngokuhlangabezana nezici ezingenhla, kodwa futhi sinezinzuzo "zekhwalithi ephezulu nentengo enhle kakhulu". Izitofu zethu zensimbi engagqwali zithengiswa emazweni amaningi emhlabeni jikelele, zinikeza izitofu zekhwalithi ephezulu emindenini eminingi namabhizinisi. Siyakwamukela esitolo ukuzothenga.
