Refined qab zib: txoj kev ntawm tau txais

Refined qab zib, nyob rau hauv sib piv rau ib tug yooj yim qab zib, ib tug ntau dua degree ntawm purification. Cov lag luam tawm qab zib producers mov nyob rau hauv ntau yam ntaub ntawv: hmoov, xuab zeb los yog compacted. Technology, uas yog tau ua los ntawm refined qab zib, yooj yim, yog siv raws li ib tug raw khoom beet los yog pas nrig khoom. Tiav lawm cov khoom ntawm ob lub pib cov ntaub ntawv uas cov ntau ntau yam mus saj yuav luag tib yam, tab sis txawv cov nqi. Qhuav ntawm ua kom zoo qab zib los ntawm pas nrig raw khoom yog kim kim thiab yuav siv sij hawm ntev.

Lub essence ntawm txoj kev txais lub lim cov khoom no yog npaj ib tug nyeem tshuaj uas yog ces pauv mus rau ib phoov lub xeev rau ntxiv txhij txhua adsorption thiab pom. Tom qab lub resulting loj yog muab tso rau hauv ib lub tshuab nqus ntaus ntawv, nyob rau tag nrho cov xeev yog coj mus hws. Yuav kom nws hais muaj ib tug snow-dawb xim, nws yog kho nrog ib ncua kev kawm ntawm ultramarine (khoom noj khoom haus coloring).

Nyob rau hauv lub kauj ruam tom ntej, ua neeg dawb huv qab zib muaj peev xwm yuav tsim nyob rau hauv ob txoj kev, nyob ntawm seb yuav ua li cas qhov kawg khoom - molded los yog extruded. Cov kev xaiv thawj yog kim kim thiab nyuab. Thaum nws ua neeg dawb huv qab zib tau los ntawm pouring loj (massecuite) rau hauv tshwj xeeb ntaub ntawv, qhov chaw uas nws maj freezes. Yuav kom tshem tawm cov lub syrup yog poured rau sab saum toj ntawm ib tug tov ntawm ua kom zoo qab zib, qhov no txoj kev yog pheej rov qab peb los yog plaub lub sij hawm. Raws li ib tug tshwm sim, ua rau cov cov khoom tiav yog muab tshem tawm los ntawm lub pwm thiab muab faib ua yam loj ntsuas. Nws yog yooj yim npaum li thiab pheej yig dua kom tau refined qab zib molded txoj kev, thaum lub syrup ntxuav hniav dawb tshwm sim nyob rau hauv ib tug tshwj xeeb centrifuge. Cov resultant khoom compressed phais thiab qhuav, thiab ces nraug cov khoom loj rau hauv parallelepipeds.

Feem ntau, cov kev ntsuam xyuas los ntawm cov khoom ua organoleptic txoj kev, los ntawm kev txiav txim saj, tsw, xim, clarity ntawm cov tshuaj. Xim ntawm ua kom zoo zoo tshuaj yuav tsum tau dawb uas tsis muaj tsuas thiab huv si, tej zaum ib tug xiavlus zas. Lub saj yog qab zib, tsis muaj lwm yam flavors, lub Tib yam siv rau lub tsis hnov tsw. Cov tshuaj yuav tsum tsis txhob muaj impurities precipitate thiab tsum pob tshab los yog me ntsis opalescent. Ntawm cov physicochemical thaj chaw ntawm lub tseem ceeb tshaj plaws yog:

- loj zauv feem ntawm sucrose, ya raws, txo tshuaj;

- ferroprimesey cov ntsiab lus;

- xim;

- Fortress.

Tsis tas li ntawd tseem ceeb yog cov sib txawv microbiological yam ntxwv: poov xab, pathogens, pwm, MAFAM, BGKP3. Mus txog qhovtwg tshuaj tua kab (Fostoksin, hexachloran), thiab tej yam tshuaj lom (arsenic, cadmium, hmoov txhuas, mercury, tooj liab, zinc). Ntim khoom nyob rau hauv daim ntawv ntawm cov xuab zeb thiab hmoov nyob rau hauv packets, thiab pob qab zib - nyob rau hauv ib tug neeg cartons los yog hnab (2 ib daim ntawm parchment daim duab thiab wrapper).

Tsheb thauj mus los thiab cia ntawm ua kom zoo qab zib yog nqa tawm nyob rau hauv ntim los yog nyob rau hauv kaw tsheb. Tsheb, tuas, ntim yuav tsum tsis txhob muaj kev ncua thiab yuav qhuav, lub-ru tsev yuav tsum tsis txhob hla dej, qhov rooj thiab hatches - nruj nreem kaw. Cov khoom yuav tsum tau khaws cia nyob rau hauv ib tug humidity ntawm tsis ntau tshaj 70% thiab ib tug kub tsis siab tshaj 40 ° C, ua tib zoo sib cais los ntawm lwm yam tshuaj thiab cov ntaub ntawv.
