Pob
Khoom noj khoom haus qib titanium dioxideyog cov ntxhia hauv ntuj siv los ua cov tshuaj ntxuav hniav dawb thiab opacifying nyob rau hauv ntau yam khoom noj, nrog rau cov khoom qab zib txheej. Nws yog ntau yam thiab muaj kev nyab xeeb ntxiv tau pom zoo siv rau hauv cov zaub mov los ntawm cov koom haum tswj hwm thoob ntiaj teb, suav nrog US Food and Drug Administration (FDA) thiab EU European Food Safety Authority (EFSA).
Hauv kev tsim khoom qab zib, Khoom noj khoom haus qib titanium dioxide yog siv los tsim cov xim ci, opaque uas txhim kho qhov pom kev pom ntawm cov khoom kawg. Nws muaj txiaj ntsig tshwj xeeb ntawm kev ua tiav cov xim ci thiab zoo ib yam hauv cov khoom qab zib txheej, ua rau nws yog ib qho tseem ceeb ntawm cov khoom qab zib thiab cov khoom qab zib.
Ib qho ntawm cov khoom tseem ceeb ntawm Cov Khoom Noj Qib titanium dioxide yog nws lub peev xwm los cuam tshuam thiab tawg lub teeb, uas pab tsim kom muaj qhov sib luag, ci ntsa iab ntawm qhov chaw.khoom qab zib txheej. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog rau cov khoom qab zib tawv tawv, xws li coated chocolates thiab khoom qab zib-coated txiv ntoo, qhov twg cov tsos ntawm cov txheej yog qhov muag tseem ceeb.
Ntxiv rau nws txoj kev zoo nkauj, zaub mov qib titanium dioxide kuj ua lub luag haujlwm tseem ceeb hauv cov khoom qab zib txheej. Nws pab txhim kho qhov kev ntxhib los mos thiab qhov ncauj qhov ntswg ntawm txheej, muab nws ib tug du thiab creamy sib xws uas txhim khu kev noj qab haus huv tag nrho. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog rau confections uas yog npaj rau kev hnov lus tsis txaus siab, vim tias qhov kev ntxhib los mos ntawm txheej tuaj yeem cuam tshuam rau kev xaav ntawm cov khoom.
Txawm hais tias titanium dioxide tau siv dav hauv kev lag luam khoom noj, tseem muaj qee qhov kev tsis sib haum xeeb nyob ib puag ncig kev nyab xeeb ntawmtitanium dioxide hauv cov khoom noj. Qee qhov kev tshawb fawb tau ua rau muaj kev txhawj xeeb txog kev pheej hmoo ntawm kev noj qab haus huv los ntawm kev noj titanium dioxide nanoparticles, uas yog cov ntxhia me me uas yuav muaj cov khoom sib txawv dua li cov khoom loj.
Txawm li cas los xij, nws tsim nyog sau cia tias cov zaub mov qib titanium dioxide yuav tsum tau ua raws li kev tswj hwm nruj thiab kev ntsuas kev nyab xeeb los ntawm cov koom haum tswj hwm zaub mov. Kev siv cov zaub mov-qib titanium dioxide hauv cov khoom qab zib txheej yog nruj me ntsis tswj xyuas kom nws ua tau raws li cov qauv kev nyab xeeb thiab tsis ua rau muaj kev pheej hmoo rau cov neeg siv khoom.
Hauv kev xaus, cov zaub mov qib titanium dioxide ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom qab zib zoo nkauj thiab pom kev zoo nkauj uas peb txhua tus nyiam. Nws muaj peev xwm txhim kho xim, txhim kho kev ntxhib los mos thiab muab lub ntsej muag glossy ua rau nws yog ib qho tseem ceeb ntawm cov khoom lag luam confectionery. Nrog cov kev cai nruj nyob rau hauv qhov chaw kom ntseeg tau tias lawv muaj kev nyab xeeb, cov neeg siv khoom tuaj yeem txuas ntxiv txaus siab rau lawv cov khoom qab zib-coated yam tsis muaj kev txhawj xeeb txog kev siv cov khoom noj-qib titanium dioxide.

Uniform particle loj:
Khoom noj khoom haus-qib titanium dioxide sawv tawm rau nws qhov loj me me. Cov cuab yeej no ua lub luag haujlwm tseem ceeb hauv kev txhim kho nws qhov kev ua tau zoo raws li cov khoom noj ntxiv. Qhov loj me me ua kom muaj kev ntxhib los mos thaum lub sijhawm tsim khoom, tiv thaiv clumping lossis tsis sib xws. Qhov kev ua tau zoo no ua rau cov khoom sib txawv ntawm cov khoom ntxiv, uas txhawb cov xim sib xws thiab kev ntxhib los mos thoob plaws ntau yam khoom noj.
Zoo dispersion:
Lwm qhov tseem ceeb ntawm cov zaub mov qib titanium dioxide yog nws qhov zoo tshaj plaws dispersibility. Thaum ntxiv rau cov zaub mov, nws disperses yooj yim, kis tusyees thoob plaws hauv lub mix. Qhov no feature ua kom ib tug txawm tis ntawm additives, uas ua rau cov xim zoo ib yam thiab nce stability ntawm cov khoom kawg. Kev txhim kho kev tawg ntawm cov zaub mov qib titanium dioxide ua kom nws cov kev sib xyaw ua haujlwm zoo thiab txhim kho qhov pom kev pom ntawm ntau yam khoom noj.
Pigment zog:
Khoom noj khoom haus qib titanium dioxide yog dav siv los ua cov xim vim nws cov yam ntxwv ua tau zoo. Nws cov xim dawb ci ua rau nws muaj kev xaiv nrov rau kev siv xws li khoom qab zib, khoom noj siv mis thiab khoom ci. Tsis tas li ntawd, nws cov xim pigment muab cov opacity zoo heev, uas yog qhov tseem ceeb rau kev tsim cov khoom noj khoom haus zoo nkauj thiab pom kev zoo nkauj. Khoom noj khoom haus qib titanium dioxide txhim kho qhov pom kev pom ntawm cov khoom noj, ua rau nws muaj txiaj ntsig zoo hauv ntiaj teb ua noj.
