Txhua tus paub cov khoom xws li mis condensed. Txawm li cas los xij, ntau tus tsis paub txog kev siv tshuab ntawm nws cov khoom tsim, muaj pes tsawg leeg, nrog rau qhov zoo thiab qhov tsis zoo ntawm lub cev. Cov ntaub ntawv hauv qab no yuav pab tus neeg nkag siab tias lawv noj dab tsi tiag.

Nyob ntawm kev tsim cov thev naus laus zis, cov hauv qab no cov kaus poom mis nyuj muaj qhov txawv:

• Abiosis. Nws yog kub sterilization ntawm raw cov ntaub ntawv. Hom no suav nrog sterilized condensed mis nyuj cov ntsiab lus nruab nrab thiab cov roj tsawg, mis nyuj nrog cov khoom noj ntxiv, thiab lwm yam.
• Suspended animation. Qhov no yog lub thickening ntawm raw cov ntaub ntawv. Cov no suav nrog condensed skimmed mis nyuj, buttermilk thiab whey, sweetened condensed mis nyuj, kas fes thiab cocoa nrog condensed mis nyuj, sweetened condensed buttermilk, thiab lwm yam.
• Xeroanabiosis. Hauv lwm lo lus, cov no yog cov kua mis qhuav qhuav. Xeroanabiosis cov khoom muaj xws li mis nyuj hmoov 20% thiab 25% rog, cov khoom noj siv mis nrog zaub roj, thiab lwm yam.

Technology ntawm cov kaus poom mis nyuj yog qhov concentration ntawm cov khoom qub. Ib tug feature ntawm cov txheej txheem noyog kev ua cov khoom siv raw thaum khaws cia rau hauv lub xeev thim rov qab.

Storage rules

txoj cai cia rau cov khoom mis nyuj hauv kaus poom yuav txawv nyob ntawm seb lawv hom.

Yog li, cov mis nyuj qab zib yuav tsum tau khaws cia rau hauv lub ntim ntim ntawm qhov kub tsis tshaj kaum degrees Celsius. Lub neej txee ntawm cov khoom nyob rau hauv rooj plaub no yuav yog qhov siab tshaj plaws ntawm 12 lub hlis. Txoj cai khaws cia kas fes nrog condensed mis nyuj yog tib yam. Txawm li cas los xij, yog tias qhov ntsuas kub ntawm lub chamber uas nws nyob tsis tau tswj, ces lub txee lub neej yuav txo mus rau 3 lub hlis.

sterilized mis nyuj yuav tsum muab cia rau ntawm ib tug txheeb ze humidity ntawm 80-85% thiab kub ntawm 0 ° C mus rau +10 ° C. Lub neej txee - 12 lub hlis.

Nyob rau hauv qhov chaw tsim khoom, cov mis nyuj hauv kaus poom raug tso cai khaws cia tsis pub dhau plaub lub lis piam ntawm qhov kub ntawm 0 ° C txog + 10 ° C, thiab tsis pub ntau tshaj ob - ntawm 10-20 ° C.

Raw khoom ntsuas zoo

Kev nyab xeeb ntawm cov khoom ncaj qha nyob ntawm cov mis nyuj, nrog rau kev ua tiav ntawm nws.

Ua ntej tshaj plaws, cov khoom qub yuav tsum tsis txhob muaj ntxhiab tsw lossis saj. Cov kev cai tshwj xeeb kuj raug txwv rau thermal stability ntawm cov mis nyuj, uas yuav tsum muaj tus nqi siab. Qhov ntsuas no yog ntsuas los ntawm kev ntsuas cawv. Thermal stability yog ib qho tseem ceeb hauv kev tsim cov mis nyuj condensed. Ua tsaug rau nws, cov kws tshaj lij txiav txim siab qhov zoo thiab qhov zoo ntawm cov khoom qub.

Kev saib xyuas yog them rau qhov piv ntawm cov protein, rog thiab carbohydrates hauv cov mis nyuj. Cov rog tau txais kev saib xyuas tsawg dua. Txawm li cas los xij, lawvQhov piv rau cov proteins yuav tsum yog li 0.4-0.42. Ib yam khoom uas muaj nqi qis dua yog suav tias tsim nyog rau kev khaws cia, tab sis tsis yog rau thickening lossis ziab.

Condensed kaus poom mis nyuj: GOST

Cov khoom noj hauv kaus poom yog ua raws li cov kev cai tshwj xeeb (GOST), uas suav nrog cov khoom hauv qab no:

1. yam ntxwv. Cov kab lus no qhia tag nrho cov kab mob organoleptic (sab, tsw, xim, tsos) thiab physico-chemical (feem feem ntawm cov rog, noo noo, sucrose, thiab lwm yam) ntsuas ntawm cov khoom.
2. Rau cov khoom siv raw. Txhua yam uas siv rau hauv kev tsim cov kaus poom mis nyuj yuav tsum ua ntej ntawm tag nrho cov ua raws li tam sim no TNLA (txoj cai tswj kev cai lij choj) ntawm Lavxias teb sab Federation. Hauv kev tsim cov khoom, kev siv cov khoom siv raw, ob qho tib si hauv tsev thiab txawv teb chaws, tau tso cai.
3. Kev. Nws yog siv rau cov neeg siv khoom thiab cov thawv thauj khoom, pab pawg ntim khoom thiab mus rau pob khoom thauj. Tsis tas li ntawd, cov khoom lag luam tau txais kev thauj mus los, qhov chaw kos npe "kom deb ntawm noo noo" yog siv rau lub ntim.
4. Ntim. Cov ntaub ntawv uas siv rau hauv cov txheej txheem ntim cov khoom yuav tsum ua raws li cov ntaub ntawv tshwj xeeb, nrog rau xyuas kom muaj kev nyab xeeb ntawm cov khoom zoo thaum nws thauj, khaws cia thiab muag.

Ua raws li GOST hauv kev tsim khoom yog qhov tseem ceeb heev. Nws txoj kev ua txhaum cai yuav ua rau txo qis hauv qhov zoo thiab lwm yam kev ntsuas ntawm cov khoom.

Dab tsi txiav txim siab xim, tsw qab thiab lwm yam khoom ntawm cov khoom?

Qhov tsis muaj ntawm cov khoom kawg nyob ntawm:

• zoo ntawm cov khoom siv raw;
• technological parameters;
• zoo ntawm cov khoom ntim, cov khoom ntxiv thiab cov khoom ntim;
• terms and storage technology.

Nyob rau hauv tsos thiab xim, cov mis nyuj hauv kaus poom nthuav tawm ib qho chaw huv thiab ci. Cov xim ntawm cov khoom yog cuam tshuam ncaj qha los ntawm qhov zoo ntawm cov mis nyuj siv hauv kev tsim cov fillers thiab additives.

Cov qauv thiab qhov sib xws nyob ntawm qhov kev faib tawm ntawm cov roj globules thiab cov protein, cov ntsiab lus qhuav hauv cov khoom, nws cov acidity, pasteurization kub, homogenization efficiency, kub thiab ntev ntawm thickening, nrog rau cov cua txias.

Qhov tsw thiab saj ntawm cov kaus poom mis nyuj hauv lawv cov khoom organoleptic yuav tsum kwv yees li zoo li cov mis nyuj pasteurized tshiab. Thaum lub sij hawm thickening, cov ntsiab lus ntawm volatile yam uas muaj nyob rau hauv nws yog txo mus rau 15%, uas txhim kho saj ntawm cov khoom kawg.

khoom siv tau zoo

Cov mis nyuj hauv kaus poom yog suav tias yog ib qho khoom noj qab zib zoo tshaj plaws, vim nws muaj ntau cov calcium, vitamins, minerals thiab lwm yam khoom muaj txiaj ntsig.

Lwm "khoom qab zib" muaj tib yam khoom. Txawm li cas los xij, tsis zoo li tib lub mis condensed, cov poov xab ntxiv rau lawv thaum lub sij hawm tsim khoom, nrog rau ntau cov zaub mov xim thiab cov khoom ntxiv.

Los ntawm qhov muaj cov tshuaj muaj txiaj ntsig, ntau tus kws tshaj lij piv cov mis condensed nrog cov mis nyuj zoo tib yam, uas nyob rau hauv cov txheej txheem ntawm condensingpoob ib feem me me ntawm cov khoom zoo. Cov calcium uas muaj nyob rau hauv cov khoom pab txhim kho pob txha thiab cov ntaub so ntswg. Thiab sib npaug phosphorus ntsev yuav pab txhim kho kev ua haujlwm ntawm cov hlab ntsha thiab lub hlwb.

Yuav ua mob rau lub cev

Qhov teeb meem tseem ceeb rau tib neeg kev noj qab haus huv yog qab zib, uas tsuas yog ib qho loj hauv cov mis nyuj khov. Yog li, cov neeg uas haus cov khoom hauv qhov ntau yuav muaj kev pheej hmoo ua rau muaj kev phom sij tsis tuaj yeem:

• Teeb. Raws li koj paub, qab zib yog cov khoom noj nyiam ntawm cov kab mob uas sib sau ntawm cov hniav enamel. Sij hawm dhau mus, cov kab mob pathogenic yuav ua rau cov hniav enamel thinner kom txog thaum caries tshwm.
• Daim tawv nqaij. Kev nplua nuj ntawm cov khoom no hauv cov khoom noj yuav ua rau cov tsos mob ntawm cov kab mob hauv plab hnyuv. Cov kab mob no lawv tus kheej yuav ua rau ntau yam pob khaus ntawm lub ntsej muag, hauv siab, nraub qaum thiab lwm qhov hauv lub cev.

Rau lub cev tag nrho. Nrog rau kev siv cov khoom lag luam tas li hauv qhov ntau, ib tus neeg yuav pib muaj teeb meem nrog cov hlab plawv thiab cov hlab ntsha (vim muaj cov piam thaj ntau dhau hauv cov ntshav), yuav muaj kev pheej hmoo ntawm kev tsis haum tshuaj, thiab lwm yam

Nws tuaj yeem xaus lus tias kev siv cov kua mis hauv kaus poom yuav tsis ua mob rau koj txoj kev noj qab haus huv yog tias koj siv lawv raws li qhov tsim nyog. Cov kws tshaj lij tsis pom zoo kom tshaj qhov nyiaj pub dawb txhua hnub ntawm 2-3 tablespoons.
