Uma wake wazibuza ukuthi ingxube yakho yezinongo ihlala ikhululekile ngisho nangemva kwezinyanga ishalofini, noma kungani impushana yesiphuzo ingahlangani uma umswakama usuthinta, kungenzeka ukuthi ungabonga i-hydrophobic fumed silica food grade. Lokhu akusona isithako esijwayelekile sasekhishini — iyisengezo esisebenza kahle kakhulu esiphethwe ukuze sixoshe amanzi ngenkathi siphephile ukuthi singadliwa. Ngokungafani ne-silica evamile, emunca umswakama njengesipontshi, inguqulo ye-hydrophobic yakhelwe ukugcina amanzi ngaphandle, okwenza kube yisixazululo esiyisisekelo kubakhiqizi abadinga ukuthi izimpushana nama-emulsion aziphathe ngokungaguquki. Uzoyithola ibhalwe ohlwini lwezithako ngaphansi kwamagama afana ne-silicon dioxide noma i-silica dioxide food additive, kodwa okubalulekile yilokho eyenza ngaphakathi komkhiqizo. Ihlala phakathi kwezinhlayiya, ivimbela ngokomzimba ukuthi zingahlangani, futhi yenza konke lokhu ngamanani asezingeni eliphansi kakhulu — sikhuluma ngezingxenyana zephesenti. Lowo uhlobo lokusebenza kahle oluthandwa onjiniyela bokudla ngoba luxazulula izinkinga zangempela zokukhiqiza ngaphandle kokuphazamisa ukunambitheka noma ukubukeka komkhiqizo wokugcina. Futhi uma sikhuluma iqiniso, akekho ofuna ingxube ye-gravy ephenduka isitini nje uma umswakama ukhuphuka.

Ngakho-ke ubani owenza lokhu ngezinga elikhulu ngokungaguquguquki okungenzeka ukuthi izinkampani zokudla zibeke izimpawu zazo kukho? Lapho-ke i-I-Shandong Zhonglian Chemical Co., Ltd.ingena emfanekisweni. Akusona isenzo esisheshayo — sebenze iminyaka, bephethe imigqa eminingi yokukhiqiza ezindaweni zabo eChina, futhi bakhe idumela mayelana nokulawulwa kwekhwalithi okungahlolwa kalula. Yonke inqubo yabo yokukhiqiza i-hydrophobic fumed silica food grade ihlelwe kusukela ekutholeni izinto ezingavuthiwe kuze kube ukupakishwa kokugcina, futhi banesitifiketi se-ISO9001, okusho ukuthi abakhulumi nje ngekhwalithi. Baphinde babe nabasebenzi abazinikele be-R&D abachitha izinsuku zabo befunda ukuthi bangayilungisa kanjani usayizi wezinhlayiya, ukwelashwa kwendawo, namazinga obumsulwa ukuze bahambisane nalokho okudingwa umthengi. Uma ungumphathi wokuthenga noma usosayensi wokudla, ukwesekwa okunjalo kwezobuchwepheshe kubalulekile ngoba awuthengi nje impuphu — uthenga ukuvumelana inqwaba ngemva kwenqwaba. Futhi ithimba lakwaZhonglian liyakuqonda lokho. Bakhiphe konke kusukela ezilingweni ezincane kuya emithwalweni egcwele yezitsha zezinkampani zokudla zamazwe ngamazwe, ngakho-ke babone izinkinga eziphakama lapho imininingwane iphambuka, futhi baklama inqubo yabo ukuze bagweme lokho kuphambuka ekuqaleni. Ungangena ekujuleni komlando wabo kuwebhusayithi yabo.Ikhasi Lethu uma ufuna indaba ephelele.

Ake sikhulume ngemininingwane ngoba umlingo we-hydrophobic fumed silica food grade awuwona umlingo nhlobo — inhlanganisela yezici zomzimba namakhemikhali ezakhiwe ngamabomu ngesikhathi sokukhiqiza. Okokuqala, izinga lobumsulwa liphakeme, ngokuvamile lingaphezu kuka-99.8 ekhulwini le-silicon dioxide ngemva kokwelashwa, okusho ukuthi akukho okungadala ukungemnandi, ukushintsha umbala, noma izinkinga zemithetho. Lokho kubalulekile ngoba abahloli bokuphepha kokudla babheka kahle noma yini engezwa emkhiqizweni, futhi uma i-anti-caking agent yakho iletha ukungcola, unokukhumbula okulindele ukwenzeka. Okwesibili, usayizi wezinhlayiya umncane kakhulu, ngokuvamile usukela ku-7 kuya ku-40 nanometers ubukhulu be-primary particle, okunikeza indawo enkulu kakhulu uma kuqhathaniswa nesisindo sayo. Leyo ndawo yiyona eyenza kube yi-food grade anti-caking agent esebenza kahle — imboza ingaphezulu lezinhlayiya eziphethe enhlanganisweni eyimpuphu eyomile futhi ivimbe ukwakheka kwamabhuloho awuketshezi phakathi kwazo lapho umswakama uzama ukungena. Okwesithathu, ukwelashwa kwe-hydrophobic (ngokuvamile kusetshenziswa i-silane-based coating) kwenza ingaphezulu lezinhlayiya lichithe amanzi, ngakho-ke ngisho nasezindaweni ezinomswakama ophezulu noma ngesikhathi sokugcinwa ezindaweni ezingasogwini, i-silica iyaqhubeka nokusebenza kwayo esikhundleni sokugcwala nokuhlangana. Lezi zici futhi ziyenza isebenze njenge-free-flow agent powder ethembekile egcina imigqa yokukhiqiza iqhubeka ngaphandle kwezithiyo.

Ungamangala ukuthi ziningi kangakanani izinhlobo ezahlukene zemikhiqizo yokudla ezincike kule nto. Uma uhamba kunoma yimuphi ugwalo lwezitolo, uzobona izimpawu zayo yonke indawo uma wazi ukuthi ubhekeni. Emaswazini ezinongo eziyimpuphu, ezingxube zezinongo, kanye nezingxube zesobho, i-hydrophobic fumed silica food grade isebenza njengesithako esiyinhloko sokuvimbela ukunqwabelana, esivimbela izithako ezinjengosawoti, ushukela, nesitashi ukuthi zihlangane zibe yizigaxa. Akukhona nje ukubukeka kuphela — lapho izimpuphu zihlangana, azilinganisi kahle emishinini yokugcwalisa ezenzakalelayo, okusho ukuthi uthola izingxenye ezingalingani kanye namakhasimende athukuthele. Emaswazini anamafutha amaningi njengama-coffee creamer, ama-protein isolates, kanye nezingxube zikashizi owomile, i-silica nayo idlala indima njengesithako esenza impuphu ihambe kahle, igcina amafutha engafinyeleli ebusheni futhi ingabangeli ukunamathela. Abanye abakhiqizi bayisebenzisa njengesithako sokujiya ukudla ezinhlelweni eziwuketshezi lapho bedinga ukushintsha ukujiya ngaphandle kokushintsha ukunambitheka. Futhi uma wenza izembatho zamasaladi, amasoso, noma amafutha anambitheka, i-silica efanayo ingasebenza njengesithako esizinzisa i-emulsion, igcina uwoyela namanzi engahlukani abe yizingqimba ezingezinhle eshalofini. Ngaphandle kwalokho, isetshenziswa eziphuzweni eziyimpuphu, ezingxubeni zokubhaka, kanye nakwezinye izithako ezinomsoco ukuze kwandiswe isikhathi sokuphila kwemikhiqizo ngokuvimbela ukubola okubangelwa umswakama. Ukusebenza kwayo okuhlukahlukene kuyamangalisa ngesithako esisodwa iningi labathengi abangakaze balizwe.

Thatha into elula njengoshizi we-Parmesan ogayiwe obekwe embizeni yokuhlwaya. Ngaphandle kwe-agent yokuvimbela ukunamathela ekilasini lokudla efana ne-hydrophobic fumed silica, izinhlayiya zikashizi zimunca umswakama osemoyeni, amafutha athambe, futhi emva kwamasonto ambalwa uba nesigaxa esiqinile esingeke siphume embizeni noma ngabe ushaya kangakanani. Izinhlayiya ze-silica zihlala phakathi kwezimvuthu zikashizi, zihlukanise, futhi zimunca wonke umswakama ozama ukuvala igebe. Umqondo ofanayo usebenza kumixube yesobho esheshayo, izimpushana zekokho, ngisho namanye ama-protein bar lapho izithako eziyimpushana zidinga ukuhlala zigeleza kahle ngesikhathi sokuhlanganiswa.

Uma ihlanganiswe ezinhlelweni eziwuketshezi, i-hydrophobic fumed silica food grade ingakha inethiwekhi enezinhlangothi ezintathu ekhulisa ukujiya futhi ivimbele ukugcwala. Lokhu kuyenza ibe usizo njengesithambisi sokudla kumasoso, amagravy, kanye nama-concentrated flavor pastes lapho ufuna khona umzimba nokunamathela ngaphandle kokwengeza isitashi noma i-gum engashintsha ukuzwa emlonyeni. Iphinde yenze umsebenzi ophindwe kabili njenge-emulsion stabilizer food additive emikhiqizweni efana ne-mayonnaise nama-vinaigrettes, lapho izinhlayiya ze-silica ziqoqana khona endaweni yokuhlangana kukawoyela namanzi futhi zivimbele ngokomzimba ukuhlangana. Lokhu kuyinto enkulu ngoba ama-emulsion aphukayo ayimikhiqizo ebuyiselwa emuva, futhi akekho ofuna lokho.

Imakethe yomhlaba wonke ye-silica yezinga lokudla ikhula ngokuqhubekayo, futhi izinombolo ziyakusekela lokho abakhiqizi abaningi abakuthola ngqo. Ngokusho kokuhlaziywa kwemakethe kwakamuva okuvela ezinkampanini ezinjengeGrand View Research kanye neTransparency Market Research, imakethe iyonke ye-silicon dioxide yezinhlelo zokusebenza zokudla neziphuzo kulindeleke ukuthi ikhule ngezinga lokukhula elihlanganisiwe lonyaka elingaba ngu-5 kuya ku-7 amaphesenti eminyakeni embalwa ezayo, ikakhulukazi ngenxa yesidingo sokudla okulungiselelwe okulula, imikhiqizo enomsoco eyimpuphu, nezindlela ezihlanzekile zokumaka. I-hydrophobic fumed silica yezinga lokudla ikakhulukazi ibona ukwamukelwa okukhulayo ngoba isebenza emazingeni aphansi womthamo uma kuqhathaniswa nezinto ezivimbela ukunamathela ezivamile ezifana ne-calcium silicate noma i-magnesium stearate, okuholela ekongeni izindleko kanye nezinto ezihlanzekile zokwakha. Abakhiqizi abashintshela ku-hydrophobic fumed silica bavame ukuthola ukuthi banganciphisa amazinga okusebenzisa ngama-30 kuya ku-50 amaphesenti ngenkathi befinyelela ukusebenza okufanayo noma okungcono kokugeleza. Lokho kuyimpikiswano enamandla uma uthola izinto ngezinga elikhulu. Ungagcina ulandelela intuthuko yemboni ngeIsigaba Sezindaba esizeni se-Zhonglian, lapho bethumela khona izibuyekezo mayelana nezinguquko zemithetho kanye nocwaningo lokusetshenziswa.

Bheka, akukho okuphelele, futhi i-hydrophobic fumed silica food grade inomkhawulo wayo wokufunda. Inkinga enkulu abakhiqizi abaningi abahlangabezana nayo umthamo — usebenzisa kancane kakhulu ngeke uthole umphumela wokuvimbela ukubumba noma wokujiya owudingayo, kodwa uma usebenzisa kakhulu ungakhiqiza umkhiqizo onothuli ongathandeki ukuwusingatha futhi ungase uthinte nokuzwa komlomo. Ububanzi bomthamo osebenzayo ngokuvamile buphakathi kuka-0.1 no-2 amaphesenti ngesisindo ngokuya ngohlelo lokusebenza, kodwa kuyahluka ngosayizi wezinhlayiya zempuphu eyisisekelo, inani lamafutha, izinga lomswakamo, nezimo zokucubungula. Enye inselele ukuhambisana nezinye izithasiselo. Ekuhlanganiseni okuyinkimbinkimbi lapho uhlanganisa i-silica nezitashi, ama-gums, ama-emulsifiers, nezilondolozi, ukusebenzisana ngezinye izikhathi kunganciphisa ukusebenza kwengxenye eyodwa noma eziningi. Yingakho ithimba lobuchwepheshe likaZhonglian lincoma ukwenza izivivinyo ezincane ngaphambi kokuzibophezela ekukhiqizeni okugcwele, futhi bazosiza amakhasimende ukuthi athole izinga nomthamo ofanele. Bese kuba nenkinga yokuhlakazeka — i-hydrophobic silica ayimanzi kalula emanzini (okuyiyona nhloso), ngakho uma uyifaka ohlelweni loketshezi udinga ukusebenzisa ukuxuba okunamandla okusika noma inqubo efanele yokuhlakaza ukuze isatshalaliswe ngokulinganayo. Yeka leso sinyathelo futhi uzogcina unamabhodlo e-silica eyomile entanta ebhantshini lakho. Kuyaxazululeka, kodwa akusona into ongayixuba ngesipuni bese uthi usuyiqedile.

Uma unaka okwenzekayo embonini yokudla njengamanje, uyazi ukuthi ukuma okuhlanzekile kwelebula kanye nokusimama kuqhuba izinguquko eziningi ekwakhiweni. I-Hydrophobic fumed silica food grade empeleni ingena kahle kuzo zombili lezi zinto. Ngokombono wezomthetho, i-silicon dioxide inomlando omude wokusetshenziswa okuphephile ekudleni, futhi yaziwa ngokuthi iphephile (GRAS) yi-FDA futhi igunyazwe yi-EU nezinye izinhlaka ezinkulu zokulawula. Ngokungafani namanye ama-anti-caking agents okwenziwa ahlolisisiwe abameli belebula elihlanzekile, i-silica ivame ukungabonakali ngoba iyisihlabathi — umaminerali otholakala ngokwemvelo ocutshungulwa ukuze kuthuthukiswe ukusebenza kwawo. Ngakolunye uhlangothi lokusimama, ukukhiqizwa kwe-silica kunomthelela ophansi kwezemvelo kunezinye izinto eziningi eziphilayo, futhi abakhiqizi abafana ne-Zhonglian batshala imali ezinqubweni ezigcina amandla kanye nokunciphisa imfucuza. Kukhona nentshisekelo ekhulayo yokusebenzisa izixazululo ze-anti-caking agent ezivumela ukunciphisa imfucuza yokupakisha ngokuvimbela ukubola komkhiqizo, futhi i-silica nayo inendima lapho. Uma ingxube eyimpuphu ihlala igeleza futhi izinzile impilo yayo yonke yeshelufu, umkhiqizo omncane uyalahlwa, futhi lokho kuyimpumelelo kumkhiqizi kanye nomhlaba. Ungabheka okwaboikhathalogi yomkhiqizo ukuze ubone uhla olugcwele lwezinga le-silica abalunikezayo ngezinhlelo ezahlukene.

Kunezinkampani eziningi ezithengisa i-silica, kodwa umehluko phakathi komhlinzeki omuhle nomhlinzeki oyinkinga uvame ukwehlela ekungaguquguqukeni, ukwesekwa kwezobuchwepheshe, kanye nokuhleleka kwezinto. I-Shandong Zhonglian Chemical iqhudelana kuzo zontathu lezi zindawo. Imigqa yabo yokukhiqiza imiselwe ukukhiqiza i-hydrophobic fumed silica food grade enemibandela eqinile ekusatshalalisweni kobukhulu bezinhlayiya, ubuningi bokwelashwa kwendawo engaphezulu, kanye nobumsulwa, futhi benza ukuhlola kwekhwalithi ezindaweni eziningi enqubweni kunokuhlola nje i-batch yokugcina. Lokho kungase kuzwakale njengezinto eziyisisekelo, kodwa noma ubani othole izithako e-Asia uyazi ukuthi akubona bonke abahlinzeki abenza lokho abakusho ephepheni le-spec. I-Zhonglian iphinde inikeze izixazululo ezenziwe ngokwezifiso — uma ikhasimende lidinga usayizi othile wezinhlayiya noma indawo engaphezulu elungisiwe ukuze isebenze ngokuhambisana ne-food matrix ethile, ithimba labo le-R&D lingakwazi ukuyiklama. Futhi ngenxa yokuthi bakhe ubudlelwano nabahlinzeki bezinto zokuhambisa abaqonda izidingo zokuthuthwa kwe-food-grade (izitsha ezihlanzekile, imibhalo efanele, ukulawulwa kwezinga lokushisa uma kudingeka), bangakwazi ukuletha ngokuthembekile emachwebeni omhlaba wonke ngaphandle kwezinkinga ezivamile. Emabhendini okuthenga akhathele ukubhekana nekhwalithi engaguquki noma izikhathi zokuphendula ezinensayo, i-Zhonglian inikeza enye indlela yangempela. Ungaxhumana nabo nge-ikhasi lokuxhumana ukuze kuxoxwe ngezidingo ezithile.

Yebo, ngokuvamile yamukelwa njengephephile (GRAS) yi-FDA futhi igunyazwe ukusetshenziswa ekudleni yiziphathimandla zokulawula emhlabeni wonke kuhlanganise ne-EU ne-China. Ayisebenzi ngamakhemikhali emazingeni aphansi okusetshenziswa adingekayo, futhi idlula ohlelweni lokugaya ukudla ngaphandle kokumuncwa. Qiniseka nje ukuthi uthola kumthengisi othembekile ohlangabezana namazinga okukhiqiza okudla.

Ubuningi obujwayelekile bomthamo buphakathi kuka-0.1 wephesenti no-2 wephesenti ngesisindo, kodwa inani eliqondile lincike ezintweni ezinjengosayizi wezinhlayiya zempushana yakho eyisisekelo, inani lamafutha, izinga lomswakamo, nokuthi udinga ukuthuthukiswa okungakanani kokugeleza. Qala emazingeni aphansi bese wenza izivivinyo ezincane ukuze uthole indawo enhle.

Impela. Uma ihlanganiswe kahle ngaphansi kokusikwa okunamandla, yakha inethiwekhi enezinhlangothi ezintathu ekhulisa ukujiya futhi inikeze umzimba kumasoso, okokugqoka, kanye nokugxilile. Isebenza kahle kakhulu ezinhlelweni ezinamafutha noma ezinomswakamo ophansi lapho izitashi zendabuko noma ama-gum angase angasebenzi njengoba kulindeleke.

I-Hydrophilic silica ayiphathwa futhi imunca amanzi kalula, okwenza ilungele ukuwugqinsi amasistimu asekelwe emanzini. I-Hydrophobic silica yelashwe ngaphezulu ukuze ixoshe amanzi, okwenza isebenze kakhulu njenge-anti-caking agent emikhiqizweni eyimpuphu eyomile nanjenge-emulsion stabilizer emasistimini kawoyela namanzi. Udinga inguqulo ye-hydrophobic ukuze umelane nomswakama emikhiqizweni eyimpuphu.

Emazingeni okusetshenziswa ngokujwayelekile, ayinamthelela ophawulekayo ekunambithekeni, embaleni, noma ekuthinteni. Ingumgubo omhlophe, ongenakunambitheka, ongenaphunga, ohlangana ngokungabonakali. Uma uyisebenzisa ngokweqile ungase uqaphele ukuthi inhliziyo inoshukela omncane, kodwa ngaphakathi kwebanga elinconyiwe abathengi ngeke bayibone.

Ngokuvimbela ukumuncwa komswakama nokuhlangana kwezinhlayiya, kumisa ukonakala komzimba okwenza izimpushana zingathandeki noma zingasebenziseki ngokuhamba kwesikhathi. Futhi kusiza ukuvikela izithako ezibucayi njengama-flavour namavithamini ekuphulweni okubangelwa umswakama, ukuze umkhiqizo uhlale uzinze isikhathi eside.

Bheka isitifiketi sokuphathwa kwekhwalithi ye-ISO9001, izimvume zokukhiqiza ezingeni lokudla, kanye nemibhalo ekhombisa ukuthobela imithetho ye-FDA noma ye-EU nge-silicon dioxide. Abahlinzeki abafana ne-Shandong Zhonglian Chemical banikeza lezi zitifiketi futhi bangazabelana nazo njengengxenye yenqubo yokufaneleka.

Yebo, empeleni lokho kungenye yezinhlelo zayo ezisebenza kahle kakhulu. Izimpushana ezinamafutha amaningi njengezingxube zikashizi, ama-creamer, nama-protein isolates zivame ukwakha amaqhubu ngoba amafutha athambile futhi ayahamba. I-silica imboza izinhlayiya futhi ivimbele ukuthi zinganamatheli, ngisho nasemazingeni okushisa aphakeme ngesikhathi sokugcina.

Kuncike encazelweni yakho ethile yokuhlanzeka komkhiqizo. I-Silicon dioxide iyimaminerali eyenzeka ngokwemvelo futhi ivame ukwamukelwa ekwakhiweni okuhlanzekile ngoba akuyona i-polymer yokwenziwa noma ikhemikhali yokwenziwa. Ezinye izinhlangano eziqinisekisayo kanye nabathengisi bayihlukanisa njengeyamukelekile, kodwa kufanele uhlole nemakethe yakho oqondiswe kuyo noma uhlelo lokuqinisekisa.

Yigcine endaweni epholile, eyomile, emaphaketheni ayo okuqala avalekile. Nakuba i-silica ngokwayo ingangenwa umswakama, ukuchayeka isikhathi eside emswakameni ophezulu kunganciphisa ukusebenza kwayo. Gwema ukuyigcina eduze kwamakhemikhali anamandla noma amakha ngoba impuphu emihle ingamunca okuguquguqukayo emoyeni.
