Eshishini lokudla elishintsha ngokushesha namuhla, ukugcina ikhwalithi yomkhiqizo, ukuphepha, kanye nesikhathi sokuphila kuyinto ebaluleke kakhulu. Izithako zokudla zidlala indima ebalulekile ekufezeni lezi zinhloso ngokuthuthukisa ukwakheka, ukuzinza, kanye nokubukeka, ngenkathi kuqinisekiswa nokuphepha komthengi. Phakathi kwezithako lezi, i-silica esezingeni lokudla, ikakhulukazi i-Sio2 esezingeni lokudla, isivela njengesithako esingenakubuyekezwa. Izimfanelo zayo ezihlukile ziyenza ibe ukukhetha okuthandwayo ekuthuthukiseni ikhwalithi yomkhiqizo kuzo zonke izigaba zokudla ezahlukahlukene. Lesi sihloko sinikeza isibuyekezo esijulile se-Sio2 esezingeni lokudla, sihluza izimfanelo zayo, izindlela zokusebenza, izicelo ezahlukahlukene, kanye nomhlaba wokulawula oqondisa ukusetshenziswa kwayo.

Njengoba isidingo sabathengi emhlabeni wonke sokudla okuphephile nokuhlanzekile sikhuphuka, indima yezithako zokudla ezintsha ezifana ne-Sio2 food grade iba yibaluleke kakhulu. Lezi zithako azisizi nje abakhiqizi ukuthi bahlangabezane namazinga aqinile omthetho kodwa futhi zisiza ekuthuthukiseni izinqubo zokukhiqiza nokusebenza komkhiqizo. Ukuqonda lezi zinzuzo kubalulekile kochwepheshe bemboni namabhizinisi ahlose ukusebenzisa izinto ezithuthukisiwe ukuze kutholwe ikhwalithi nokuphepha kokudla okungcono kakhulu.

I-Sio2 grade yokudla, noma i-silicon dioxide ye-grade yokudla, iy-silica ye-amorphous enokuhlanzeka okuphezulu esetshenziswa kabanzi njenge-anti-caking agent kanye ne-stabilizer embonini yokudla. Ibonakala ngokukwazi kwayo okuhle kakhulu kokumunca, ukungathathi hlangothi kwamakhemikhali, kanye nendawo enkulu engaphezulu, okufaka isandla ekusebenzeni kwayo ekuthuthukiseni ukuthungwa kokudla kanye nokuvimbela ukuhlanganiswa. Lezi zici ziqinisekisa ukuthi i-Sio2 grade yokudla ayisabelani nezingxenye zokudla noma ayishintshi izici zokuzwa, okwenza iphephe ukuba isetshenziswe ngqo nemikhiqizo yokudla.

Ienziwe ukuze ihambisane namazinga aphezulu okuphepha kokudla, i-Sio2 food grade inesimemezelo se-FDA futhi ihlangabezana nezimfuneko zamazwe omhlaba ezibekwe yi-European Food Safety Authority (EFSA). Ifomu layo eliyimpuphu elimhlophe nelicwecwe liyenza ikwazi ukuhlanganiswa kalula ezinhlanganisela ezahlukahlukene ngaphandle kokuthinta umbala noma ukunambitheka komkhiqizo. Ngaphezu kwalokho, izinkampani ezifana neZhongqi (Shandong) Silicon Materials Co., Ltd. zigxile ekukhiqizeni imikhiqizo ye-Sio2 food grade esezingeni eliphezulu, ziqinisekisa ikhwalithi nokuphepha okungaguquki kwezicelo zemboni yokudla.

Umsebenzi oyinhloko we-Sio2 food grade emikhiqizweni yokudla ukuthi ikwazi ukusebenza njenge-anti-caking agent. Isakhiwo sayo esinemingxuma siyayimunca umswakama kahle, sivimbele ukuhlanganiswa kwezimpawu namagranule okungaholela ekubeni kube namathambo. Lokhu kulawulwa komswakama kubalulekile ekugcineni izici ezigeleza ngokukhululeka zezithako ezimpuphu njengezinongo, izizolisi, kanye neziphuzo ezimpuphu.

Ngaphezu kwalokho, amandla okumunca i-Sio2 food grade anweba nasekunciphiseni ukumunca igesi namafutha, okusiza ekugcineni ubusha nokunambitheka kwemikhiqizo yokudla. Lokhu kuyenza ibe usizo ikakhulukazi emikhiqizweni yobisi eyimpuphu, izimpahla ezibhakiwe, kanye nezithako zezempilo. Imvelo engathathi hlangothi yale nto eyengeziwe iqinisekisa ukuthi ayibandakanyeki ezintweni zamakhemikhali emikhiqizweni yokudla, ngaleyo ndlela igcine ubuqotho nokuphepha komkhiqizo.

I-Sio2 food grade isetshenziswa kabanzi emikhakheni yokudla eminingi ngenxa yezinzuzo zayo ezisebenza ngezindlela eziningi. Emikhiqizweni yobisi, ivimbela ukuminyana kwezimpawu futhi ithuthukisa ukuhlakazeka, ithuthukisa ulwazi lomthengi. Eziphuzweni, kusiza ukugcina ukucaca futhi kuvimbela ukuhlala phansi ezixukwini eziyimpuphu.

Izimpahla ezibhakiweyo zizuza kwi-Sio2 food grade ngokuthuthukisa ukuphathwa kwenhlama nokuvimbela ukuhlanganiswa kwezithako, okufaka isandla ekutholakaleni komkhiqizo okungaguquki. Ezingxubeni zokunonga, kuqinisekisa ukuhlanganiswa okufanayo nokulula kokupakisha. Ngaphezu kwalokho, imikhiqizo yezempilo kanye nezithako zokudla zisebenzisa i-Sio2 ukugcina ukuhamba kwe-powder nokuzinza. Ukudla okukhandiweyo kusebenzisa lokhu ukunciphisa ukwakheka kwamakristalu eqhwa ezingxenyeni zomkhiqizo, kuthuthukisa ikhwalithi ngesikhathi sokugcina nokuthutha.

I-Sio2 food grade nayo isetshenziswa kakhulu ezintweni zokupakisha ukudla ukuthuthukisa ukumelana nomswakama kanye nokuphila komkhiqizo eshalofini. Lezi zicelo ezahlukahlukene zigcizelela ukuguquguquka kwayo nokubaluleka kwayo ekwenzeni ukudla kwesimanje. Izinkampani ezifana neZhongqi (Shandong) Silicon Materials Co., Ltd. zinikeza imikhiqizo ye-Sio2 food grade eyenziwe ngendlela efanele eyenziwe ngendlela efanele yale misebenzi ehlukahlukene, isekela abakhiqizi ekufezeni ukusebenza komkhiqizo okuhle kakhulu.

Ukuvikeleka kwezithako zokudla kuyinto ebaluleke kakhulu kubalawuli nabathengi ngokufanayo. I-Sio2 food grade ihlolwe kabanzi futhi yamukelwa njengokuphephile uma isetshenziswa ngokuhambisana nemikhawulo echaziwe. Ivunyelwe izinhlangano zokulawula zomhlaba wonke ezihlanganisa i-FDA ne-EFSA, ezisungule imihlahlandlela yamaleveli aphezulu avunyelwe emikhiqizweni yokudla.

Izifundo zesayensi ziqinisekisile ukuthi i-Sio2 food grade ayinabuthi, ayibangeli umdlavuza, futhi ayiqongeleli emzimbeni womuntu. Ukungathathi hlangothi kwayo nokuncibilika kwayo okuphansi kunciphisa kakhulu noma yimaphi amathuba emiphumela emibi. Abakhiqizi abafana ne-Zhongqi (Shandong) Silicon Materials Co., Ltd. bagcizelela ukuthobela le migomo yokulawula, banikele ngemikhiqizo eqinisekisiwe ehlangabezana nezidingo zamazwe omhlaba zokuphepha kokudla. Lokhu kuzibophezela ekuphepheni nasekuqinisekisweni kwekhwalithi kuqinisekisa abathintekayo embonini yokudla nabathengi mayelana nokwethembeka kwezithako ze-Sio2 food grade.

Ngokufingqiwe, i-Sio2 food grade isebenza njengesengezo esibalulekile embonini yokudla, ithuthukisa ikhwalithi yomkhiqizo ngokusebenzisa izakhiwo zayo ezihlukile zokuvimbela ukubambana nokumunca. Ukusetshenziswa kwayo okubanzi emikhiqizweni yobisi, iziphuzo, izimpahla ezibhakiwe, izinongo, izithako zempilo, ukudla okufriziwe, nokupakisha kugcizelela ukuguquguquka kwayo. Ngomlando ophephile wokuphepha kanye nokuthobela imithetho, iyisisombululo esithembekile kubakhiqizi bokudla emhlabeni wonke.

Sibheke phambili, imizamo eqhubekayo yocwaningo nentuthuko ihlose ukwenza kahle amafomula e-Sio2 food grade ukuze kube nokusebenza kahle nokusimama okwengeziwe. Ukuqanjwa okusha yizinkampani ezifana ne-Zhongqi (Shandong) Silicon Materials Co., Ltd. kuyaqhubeka nokuqhubekisela phambili kule ndawo, kuqinisekisa ukuthi izithako zokudla zihlala zihamba phambili ekuthuthukiseni ukuphepha kwezokudla nekhwalithi. Ezinkampanini ezifuna imikhiqizo ye-silica esezingeni eliphezulu, ethembekile, ukuhlola okunikezwa ku-Imikhiqizoikhasi leZhonglian Chemical liyindawo enhle yokuqala.

Ngeminye imininingwane mayelana namakhono enkampani okusungula izinto ezintsha nokuzibophezela kwekhwalithi, vakashela ku-Mayelana Nathiikhasi, futhi uhlale unolwazi ngezinto zakamuva ezithuthukisiwe ku- Izindaba isigaba. Lezi zinsiza zinikeza imininingwane eyigugu mayelana nezinzuzo zokuncintisana kanye nobuholi bemboni obulethwa yiZhongqi neZhonglian Chemical emkhakheni wemikhiqizo ye-silica yokudla.
