Reconstituted kua txiv yog tsim rau ntawm kev lag luam nplai los ntawm ntuj tsim kua txiv. Cov kua txiv kua txiv ua kom tiav yog tau los ntawm txoj kev ntawm dej evaporation los ntawm cov kua txiv rau lub hom phiaj ntawm kev yooj yim cia thiab tsheb thauj mus los rau cov lag luam tsim cov kua txiv tshiab. Nrog rau kev ua raws li cov txheej txheem thev naus laus zis, tag nrho cov khoom noj muaj txiaj ntsig yog khaws cia hauv cov kua txiv thiab rov qab ua haujlwm, xws li hauv cov kua txiv tshiab.
Kua txiv mloog zoo siv tshuab ntau lawm
Ua tsaug rau kev thev naus laus zis niaj hnub rau kev ua cov txiv hmab txiv ntoo thiab cov txiv ntoo, txog li 80% ntawm cov vitamins thiab microelements uas tau xub pib nyob rau hauv cov ntaub ntawv nyoos yog khaws cia hauv cov kua txiv uas muaj zog. Ua kom tiav kev tsis haum rau txhua theem ntawm kev tsim khoom, ntim dej tso zis tso quav tso cai rau koj khaws cov kua txiv kom zoo rau lub sijhawm ntev yam uas tsis poob nws cov khoom qub thiab zoo.

Thiab, ntawm chav kawm, qhov zoo ntawm cov ntaub ntawv nyoos yog saib xyuas, cov txiv hmab txiv ntoo lwj thiab cov zaub tsis zoo raug pov tseg.
Concentrated kua txiv rov qab tshuab yog nqa tawm nyob rau hauv ntau theem. Cov kab mob yog ceev heev, hauv 30-40 vib nas this, rhuab mus rau 110 ° C thiab qhov ntsuas kub tiav tau tuav cia rau ob peb lub vib nas this. Qhov no yog ua tiav los ntawm cov cua txias mus rau qhov kub txog 20-22 ° C. Cov dej ntshiab uas muaj txiaj ntsig zoo yog ntxiv rau cov kua txiv kom mloog cov dej hauv txoj kev no. Tus nqi ntawm cov dej ntxiv yog sib npaug rau cov dej ntawm dej evaporated nyob rau theem ntawm tau txais cov mloog zoo.
Lub kua txiv ua tiav yog rov hloov ua dua tshiab. Txhawm rau rov qab xa cov kua txiv rau nws cov yav dhau los aroma, feem ntau ntxiv "rov qab los ntawm aroma", sib cais ua ntej lawm hauv cov txheej txheem concentration, lossis aromas tau los ntawm lwm cov thev naus laus zis. Cov pa tsw qab zoo yog tau los ntawm tev ntawm cov txiv hmab txiv ntoo thaum ua haujlwm. Thaum cov kua txiv yog rov ua dua tshiab, ascorbic acid yuav ntxiv rau ntxiv rau qee qhov ntawm cov vitamin C ploj thaum ua haujlwm. Ntxiv cov vitamins A thiab PP ntxiv.
Ntawm cov theem tom ntej, cov kua txiv ua tshiab yog pasteurized thiab nchuav rau hauv cov ntawv ntim khoom aseptic rau kev cia khoom tom qab thiab muag tom qab muag. Cov ntim khoom ntim rau cov kua txiv kab uas nrov tshaj plaws yog cov ntaub ntawv sib xyaw polymer siv los ntawm Tetra-Pak. Hauv cov ntim zoo li no, cov kua txiv tiv thaiv tau los ntawm cov pa oxygen thiab lub hnub ncaj, uas pab tswj cov kua txiv kom zoo. Ua tsaug rau kev kho kub kom sov thiab ntim khoom zoo, tsis muaj cov tshuaj ntxiv rau hauv kua txiv. Cov ntim khoom yuav tsum tau qhia tias cov kua txiv tau rov qab los ntawm ib qho tseem ceeb thiab nrog rau ntxiv ntawm cov vitamins.
Koj yuav tsum xaiv cov kua txiv raws li hnub kev tsim khoom thiab hnub tas sij hawm. Nco ntsoov xyuas qhov ncaj ncees ntawm kev ntim khoom. Nws kuj yog ib qho tseem ceeb uas tsim cov kua txiv rau. Nws yog qhov zoo dua rau kev coj cov khoom ntawm cov tuam txhab nto moo. Nws yog qhov tsim nyog yuav tau them sai sai rau qhov sib xyaw ntawm cov kua txiv thiab cov zaub mov muaj txiaj ntsig, kom paub tseeb tias tsis muaj tshuaj ntxiv.
