Rau sucrose refining, plhaub-plhaub activated carbon yuav siv tau, uas yuav siv tau rau decolorization ua ntej sucrose pulp yog crystallized ua dawb granulated qab zib. Nyob rau hauv ib sab tes, lub plhaub tshuab ua kom muaj peev xwm tuaj yeem tawm tau cog cov pigments ntawm qab zib, thiab tseem tuaj yeem nqus cov xim uas ua los ntawm cov txheej txheem (xws li melanoid thiab caramel). Cov hmoov ua kom cov roj muaj peev xwm siv tau los ua cov khoom loj thiab tom qab ntawd rov thawm hnub. Daim ntawv thov ntawm cov tshuab ua kom siv tau yog siv tau yooj yim thiab siv tau los kho cov khoom qab zib sucrose vim qhov zoo ntawm lub hauv paus pib sib txawv thiab qhov kev nplaub tshev yuav tsum tau kho rau lub hom phiaj no.
Ntuj glycerin
Lub plhaub activated carbon yog siv los ntxuav cov roj ntsha glycerin, uas yog muab los ntawm kev kub nyiab siab thiab muab cov kua roj tov thiab roj los yog roj los yog roj. Refined glycerin yog siv los ua zaub mov khoom noj kom tiv thaiv tau cov zaub mov los ntawm kev tawg los yog tiv thaiv kev hloov cov khoom noj hloov vim yog qhuav ntab. Cov cuab yeej no ua rau kev zoo siab ntawm cov khoom noj thiab cov chewiness ntawm confectionery. Cov hmoov dej ua kom siv tau los tshem tawm cov organic impurities xws li cov xim dawb thiab qee yam uas ua rau isoindoles los ntawm glycerin.
Biochemical zaub mov
Lub plhaub activated carbon thiab txiv maj phaub plhaub activated cov roj yuav tuaj yeem tawm cov phom pigments. Qhov chaw ntawm cov pigments no yog citric acid, lactic acid thiab lwm cov khoom noj biochemical. Cov hmoov ua kom cov roj muaj peev xwm siv tau los ua kom cov khoom xyaw yooj yim ua kom tiav thaum lub sijhawm fermentation. Rau qhov kawg khoom purification ntawm lactate thiab gluconate, ultra-siab purity activated carbon khoom raws li cov feem ntau stringent purification.
