Cov kua txiv hmab txiv ntoo tau tsim kom yooj yim, nws yog theem nruab nrab ntawm cov kua txiv hmab txiv ntoo tshiab thiab cov kua txiv hmab txiv ntoo rov ua dua tshiab uas ua rau lub khw muag khoom. Cov txiaj ntsig ntawm cov khoom siv raw no ua rau muaj kev tsis ntseeg ntawm cov neeg siv khoom. Puas yog lawv ncaj ncees?

Tsev tsim khoom

Cov kua txiv hmab txiv ntoo tuaj yeem muab faib raws li txoj kev tsim khoom thiab lub hom phiaj rau hauv hom: freshly squeezed, direct extraction, concentrated thiab reconstituted. Yuav kom tau txais cov kua txiv hmab txiv ntoo, nws yog ib qho tsim nyog kom tshem tawm tag nrho cov dej ntau dhau los ntawm cov kua txiv hmab txiv ntoo tshiab. Freshly squeezed - ncaj qha squeezed kua txiv uas tsis tau undergone kev ua. Concentrated kua txiv yog tsim nyob rau hauv peb txoj kev:

• Evaporation. Cov kua txiv yog muab tso rau hauv tshwj xeeb lub tshuab nqus tsev tais thiab rhuab. Tsis txhob coj mus rau boil, kom tag nrho cov txiaj ntsig ntawm cov kua txiv hmab txiv ntoo yog khaws cia. Raws li qhov tshwm sim ntawm evaporation, viscous, viscous mass tau txais, nco txog zib ntab.
• Nyob khov. Cov txheej txheem rov qab mus rau evaporation, dej ntau dhau tsis evaporated, tab sis khov.
• Membrane method. Cov kua txiv hmab txiv ntoo yog dhau los ntawm daim nyias nyias uas cais cov dej molecules ntawm txhua yam.

Tom qab tau txais cov concentrate, nws yog khov los yog pasteurized thiab cov kaus poom rau kev thauj mus los ntxiv mus rau cov khoom tsim khoom kawg. Raws li kev cia khoom zoo, nws yog qhov zoo rau 6 lub hlis mus rau ib xyoos. Cov txiv hmab txiv ntoo sib txawv muab cov ntsiab lus sib txawv. Txiv hmab txiv ntoo sau nyob rau hauv txawv teb chaws muab txawv flavors rau lub concentrate. Tib yam siv rau xyoo sau qoob thiab ntau yam txiv hmab txiv ntoo.

Specifications (GOST R 52185-2003)

Cov xwm txheej rau kev tsim cov kua txiv hmab txiv ntoo yog txiav txim siab los ntawm Lub Xeev Tus Qauv. Concentrated kua txiv hmab txiv ntoo, cov txheej txheem ntawm kev ua tau raws li cov qauv, dhau los ua cov khoom siv zoo rau kev siv ntxiv. Ntawm no yog cov kev cai rau cov khoom siv raw siv. Kev siv cov concentrated aromatic tshuaj tau los ntawm cov txiv hmab txiv ntoo ntawm tib hom yog tso cai. Nws raug tso cai siv cov khoom siv raw khoom uas tsim nyog GOST cov yam ntxwv thiab cov ntsuas kev nyab xeeb. Kev siv cov xim ntuj thiab cov khoom siv dag zog, cov tsw qab, cov tshuaj tua kab mob, tshwj tsis yog cov sorbic acid, tsis raug tso cai.

Ntim ntim, cov neeg siv khoom lossis kev thauj mus los, yuav tsum tau muab ntim nrog hermetically, xyuas kom muaj kev nyab xeeb ntawm cov khoom thoob plaws hauv lub txee lub neej. Cov kua txiv hmab txiv ntoo ntim rau hauv lub khob ntim yuav tsum tau tiv thaiv los ntawm tshav ntuj thiab lub teeb. Hnub tas sij hawm thiab kev cia khoom yog tsim los ntawm cov chaw tsim khoom.

Labeling yuav tsum muaj lub npe ntawm cov kua txiv hmab txiv ntoo, cov chaw tsim khoom, nws qhov chaw, qhov hnyav, txoj kev noj,khoom noj muaj txiaj ntsig, hnub tas sij hawm, kev cia khoom, hom kua txiv hmab txiv ntoo - qhia meej lossis tsis meej.

Cov kua txiv hmab txiv ntoo yog dab tsi rau. Siv

Cov kua txiv hmab txiv ntoo tsis yog siv los ua zaub mov. Lawv yog cov khoom nruab nrab, cov khoom siv raw. Cov kua txiv hmab txiv ntoo yog tsim los ntawm lawv, uas tom qab ntawd muag hauv khw muag khoom, thiab ntxiv rau jelly, jam, thiab lwm yam khoom. Thaum cov kua txiv rov qab los, nws dhau los ntawm cov txheej txheem rov qab - dej rov qab los rau nws. Cov cuab yeej siv rov qab muaj ntau theem, cov kev xav tau nrawm nrawm, tom qab ntawd nws kuj tseem txias sai, tsis muaj dej ntshiab, qab zib lossis lwm yam khoom qab zib ntxiv, nrog rau cov khoom qab zib uas ploj thaum lub sij hawm concentration.

Ntawm no yog cov kua txiv hmab txiv ntoo uas paub zoo, tuaj yeem yuav ntawm txhua lub khw. Nyob rau hauv cov nqe lus ntawm nws zoo, nws tsis txawv los ntawm ncaj-nias kua txiv, nws muaj tib lub zog thiab ib tug txheej ntawm cov vitamins. Vim li cas thiaj siv cov txheej txheem nyuaj? Cov kua txiv hmab txiv ntoo siv qhov chaw tsawg dua li cov kua txiv hmab txiv ntoo tshiab, ua kom yooj yim rau kev thauj thiab khaws cia. Cov thev naus laus zis no txhawb kev thauj mus los los ntawm lwm lub tebchaws. Lwm qhov ntxiv yog qhov kev mloog zoo tuaj yeem khaws cia tau ntev, thaum khaws tag nrho cov khoom muaj txiaj ntsig.

Kev faib tawm

Cov kua txiv hmab txiv ntoo yog tsim los ntawm ntau yam txiv hmab txiv ntoo hauv lub tebchaws uas cov txiv hmab txiv ntoo no loj tuaj. Qhov no tshwm sim rau cov laj thawj pom tseeb - nws yooj yim dua thiab pheej yig dua.

Raws li txoj kev hauv cov kaus poom, cov kua txiv hmab txiv ntoo tuaj yeem khov ntawm qhov kub tsis siab tshaj -18 degrees, sterilized, non-sterilized.

kua txiv apple

Kev tsim cov kua txiv apple pib nrog kev sau cov ntaub ntawv raw - txiv hmab txiv ntoo ntawm ntau yam. Hauv kev tsim khoom, ntxuav, tswj cov txiv hmab txiv ntoo zoo thiab tshem tawm cov txiv apples uas tau lwj. Los ntawm nias, ncaj qha squeezed kua txiv yog tau, los ntawm uas ib tug concentrate yuav tau npaj. Concentrated kua txiv kua txiv yog tsim los ntawm evaporation. Ua ntej, nws yog muab tso rau hauv ib lub centrifuge, qhov twg nws yog ntxuav ntawm suspensions. Tom qab ntawd nws yog rhuab nyob rau hauv ib tug tshwj xeeb installation, cov kua txiv poob 15% ntawm cov dej ntawm tag nrho cov ntim thiab cov aromatic tshuaj muaj nyob rau hauv nws, uas yog cais concentrated thiab ntim. Cov seem ntawm cov khoom siv raw yam tsis muaj cov tshuaj tsw qab yog qhia meej nrog cov enzymes, tom qab ntawd dhau los ntawm cov lim kom tau cov kua txiv hmab txiv ntoo, ces evaporated kom tau 70% cov teeb meem qhuav.

Kua txiv kua txiv concentrate muaj cov tshuaj nplua nujcompound. Nws muaj cov amino acids leucine, valine, lysine, serine, alanine, phenylalanine, tyrosine, asparagine, threonine, aminobutyric, aspartic, glutamic acids. Nws muaj ntau ntawm monosaccharides, tab sis feem ntau ntawm tag nrho nws muaj cov amino nitrogen.

txiv qaub kua txiv

Lemons tsis tau ua rau hauv cov ntsiab lus zoo li lwm cov txiv hmab txiv ntoo. Lub npe hu ua kua txiv qaub kua txiv yog nyob rau hauv cov kua dej thiab yog tsim thiab muag los ntawm ntau lub lag luam rau kev siv hauv tsev hauv cov pob yas me me. Vim nws saj, kua txiv qaub yog siv me me, thiab nws tsis muaj kev nkag siab los ua kom tuab tuab los ntawm nws thiab thauj mus rau hauv lub tank loj.

Txiv qaub tshiab twb muaj cov kua txiv hmab txiv ntoo uas muaj zog heev.

kua txiv hmab

Los ntawm cov kua txiv hmab txiv ntoo tshiab yog nias, uas yog lim kom txog thaum cov khoom siv pob tshab tsim. Los ntawm lub resulting clarified kua txiv, ib tug concentrate yog tau nyob rau hauv tshwj xeeb apparatuses nyob rau hauv lub nqus tsev vacuum. Txoj kev no khaws tag nrho cov txiaj ntsig ntawm grapes. Cov txiaj ntsig tau txais txiaj ntsig yog muab tso rau hauv lub thawv hlau lossis iav rau kev khaws cia lossis kev thauj mus los. Nws yuav tsum tau khaws cia ntawm qhov kub tsis tshaj 20 degrees.

Juiceconcentrated txiv hmab txiv ntoo yog siv tsis tau tsuas yog rau kev rov qab los, tab sis kuj nyob rau hauv zus tau tej cov cawv, dej qab zib, confectionery thiab mis nyuj industries.

Myths about store juices

Muaj kev xav tias cov kua txiv hmab txiv ntoo ntim tsis yog ntuj tsim thiab tsim siv tshuaj tua kab lossis lwm yam tshuaj. Tau nkag siab txog cov txheej txheem tsim khoom, uas yog qhov yooj yim thiab nkag siab, peb tuaj yeem xaus qhov tsis sib xws: qhov no tsis muaj dab tsi ntau tshaj li cov lus dab neeg. Concentrated kua txiv yog ib yam khoom ib nrab tiav lawm. Dej raug tshem tawm los ntawm nws tsuas yog rau kev yooj yim ntawm kev thauj mus los ntawm cov tebchaws. Thiab thaum rov qab los, nws tau ntxiv rov qab, cov kua txiv hmab txiv ntoo tau txais nws daim ntawv qub nrog zoo li tsis muaj cov khoom muaj txiaj ntsig zoo. Tsuas yog tso cai khaws cia hauv cov kua txiv hmab txiv ntoo - sorbic acid - muaj kev nyab xeeb rau tib neeg. Tsis tas li ntawd, ntim aseptic yam tsis siv cov tshuaj khaws cia ntev txog ib xyoos pab khaws cov kua txiv tshiab. Tsis tas li ntawd, cov kua txiv hmab txiv ntoo reconstituted los ntawm concentrate khaws tag nrho cov txiaj ntsig ntawm cov txiv hmab txiv ntoo uas lawv tau ua.
