Uma usebenza ekukhiqizeni ukudla, usuvele wazi ukuthi kunzima kangakanani ukugcina izithako eziyimpuphu zingahlangani ndawonye. Umswakama, ugesi omile, nobukhulu bezinhlayiya ezincane konke kuyakuvimbela — futhi lapho i-silica yezinga lokudla ingena khona. Ingenye yezinto ezisetshenziswa kakhulu ezimbonini ukuvimbela ukuhlangana, itholakala kukho konke kusukela ezingxubeni zezinongo kuya eziphuzweni eziyimpuphu eziphithizelwayo ngisho nasemikhiqizweni ethile yobisi. Kodwa ayikho yonke i-silica efanayo, futhi umehluko phakathi komkhiqizo ophephile ukudliwa nalowo ongabazekayo ungenza noma uphule umugqa wakho wokukhiqiza. I-silica yezinga lokudla isebenza njenge-free-flow agent, izisonga ngempela ezintweni ezinkulu ukuze zingahlangani. Isixazululo esilula, kodwa sidinga ukulawulwa kwekhwalithi okuqinile ukuze isebenze kahle. I-FDA yaseMelika kanye ne-European Food Safety Authority zombili zibeka amazinga aqinile obumsulwa walesi sithasiselo, futhi uma umthengisi wakho engawafinyeleli lawo mazinga, uzibeka engcupheni. Yingakho izinkampani ziba ngokukhetha kakhulu lapho zithenga khona i-silicon dioxide yazo, futhi zifuna abakhiqizi abangafakazela izinombolo zabo, i-batch ngemva kwe-batch. Noma ngabe uhlanganisa izinongo zomthengisi omkhulu noma ukhiqiza izimpuphu ezinomsoco zabasubathi, ikhwalithi ye-silica yakho ithinta ngqo ukungaguquguquki komkhiqizo wakho wokugcina kanye nesikhathi sokuphila kwawo. Abantu abaningi bacabanga ukuthi noma iyiphi i-silica izosebenza, kodwa lokho akulona iqiniso — ikakhulukazi uma kuhileleke ukudliwa ngabantu.

I-Sandong Zhonglian Chemical Co., Ltd. isineminyaka engaphezu kweshumi ikhona emdlalweni we-silica, futhi sifunde okuthile ngalokho imakethe ekudingayo ngempela. Asibona abameli abafaka ilebula ezintweni ezingenisiwe — sikhiqiza eyethu i-silica yezinga lokudla lapha e-China, silawula ngokugcwele isinyathelo ngasinye senqubo. Indawo yethu inesitifiketi se-ISO 9001, futhi okubaluleke nakakhulu, imikhiqizo yethu ihlangabezana namazinga e-FDA okuthintana okuqondile nokudla, okuyinto enkulu kunoma ubani othumela eNyakatho Melika noma eYurophu. Sineqembu elizinikele le-R&D elisebenza eduze namakhasimende ukuze lihlele ngokucophelela izimiso zezinhlayiya, ubukhulu obuqinile, namazinga omswakama ngokuya ngokusetshenziswa. Eminyakeni edlule, sihlinzeke nge-silica yezinga lokudla ezinkampanini ezingaphezu kwamazwe angama-40, futhi lokho kufinyelela emhlabeni wonke kukuphoqa ukuthi ugcine ikhwalithi yakho ingaguquki. Noma ngabe yibhikawozi elincane eNingizimu-mpumalanga ye-Asia noma inkampani yezinongo yamazwe amaningi eYurophu, bonke bathola umkhiqizo ofanayo ovela kithi.Mayelana Nathi ikhasi likhuluma kabanzi ngomlando wethu nokuhlelwa kwesikhungo sethu, kodwa inguqulo emfushane yile: sithatha i-silica ngokungathi sína ngoba idumela lamakhasimende ethu lincike kuyo. Futhi sihlala siqaphela izitayela zemboni, njengesidingo esikhulayo sezithasiselo ezinamalebula ahlanzekile kanye nokugcizelela okukhulu emazingeni aphezulu obumsulwa ekucubungulweni kokudla. Awusinde iminyaka eyishumi kulo msebenzi ngokusika amakhona — usinda ngokuletha i-silica yezinga lokudla esebenza ngempela, njalo nje.

Ake singene emininingwaneni, ngoba lapho khona kunenani langempela. I-silica yethu yezinga lokudla inezinga eliphezulu kakhulu lokuhlanzeka elingaphezu kuka-99.5% we-silicon dioxide, okusho ukuthi akukho okunye okukhona — azikho izinsimbi ezinzima, azikho izinto ezingcolisayo, azikho izinto ezingalindelekile. Silawula usayizi wezinhlayiya phakathi kuka-100 kuya ku-500 mesh, ukuze uthole ukuziphatha okungaguquki kokugeleza noma iyiphi ibhetshi oyivula. Ukumuncwa komswakama kunqunyelwe ku-3% noma ngaphansi, okubalulekile uma uyisebenzisa njenge-anti-caking agent emikhiqizweni e-hygroscopic njengosawoti, ushukela, noma ama-powdered flavors. Uma i-silica ngokwayo imunca umswakama ingakafiki engxenyeni yakho yezithako, ayenzi umsebenzi owayiqashele wona. Inqubo yethu yokukhiqiza iphinde iqinisekise ukuthi umkhiqizo uhlala ugelezela futhi ulula ukuphatha ngakho, noma ngabe usebenzisa izinhlelo zokulinganisa ezizenzakalelayo noma ukuhlanganisa ngesandla. Sihlola yonke ibhetshi nge-bulk density, i-pH, ukulahlekelwa komswakama, kanye ne-sieve residue, futhi imiphumela iyabhalwa ukuze ube nomlando ocacile wokuhlola kwakho ikhwalithi.ImikhiqizoIkhasi linemininingwane ephelele yobuchwepheshe, kodwa iphuzu eliyinhloko ukuthi i-silica yethu isebenza njenge-ejenti yokugeleza mahhala ngaphandle kokushintsha ukunambitheka, umbala, noma iphunga lokudla kwakho. Akudingeki ukukhathazeka ngokunambitheka okungajwayelekile noma izinsalela zamakhemikhali ngoba into le ayisebenzi futhi ihambisana ngokugcwele nemithetho yezithasiselo zokudla. Siphinde sinikeze ukwenziwa ngokwezifiso ngosayizi wezinhlayiya uma uhlelo lwakho lwakho lunezidingo ezithile, futhi lokho kuguquguquka akutholakali kumthengisi ngamunye. Ezinye izinkampani ziphatha i-silica yezinga lokudla njengento evamile, kodwa thina siyiphatha njengesithako esinembile — ngoba yilokho nje.

Siwenza ukuhlaziywa kwe-ICP-MS kuwo wonke amabhantshi okukhiqiza ukuze siqinisekise ukuthi umthamo wezinsimbi ezilandelwayo uhlala ungaphansi kwemikhawulo yemithetho. Lokho kusho i-arsenic, i-lead, i-mercury — akukho nakukodwa kulokhu okutholakala ku-silica yethu. Ukuhlola akukona okuzithandela; kuyinqubo ejwayelekile. Kwabakhiqizi bokudla abathumela emazweni anemithetho eqinile njenge-Japan noma i-EU, ukuba naleli zinga lemibhalo konga amasonto okukhathazeka ngesikhathi sokuhlolwa kokuthobela imithetho. Siphinde senze ukuhlaziywa kwendawo ye-BET ukuze siqonde ukuthi i-silicon dioxide yethu iziphatha kanjani ezinhlanganisweni ezahlukene, futhi siyabelana ngaleyo mininingwane namakhasimende ukuze bakwazi ukuthuthukisa izindlela zabo zokupheka. Ungamangala ukuthi bangaki abahlinzeki abangakwazi ukunikeza isitifiketi esinemininingwane sokuhlaziya uma beceliwe. Kithina, uthola izinombolo ngaphambi kwesikhathi, akukho zizathu.

Enye yezinto ezicasula kakhulu abacubunguli bokudla ukuhluka phakathi kwe-batch ne-batch kwe-silica abayithenga kwabanye abathengisi.
