Nqaij npuas yog dag ntau dua li lwm yam khoom. Cov neeg siv khoom tau nkees ntawm kev txheeb xyuas qhov degree ntawm naturalness los ntawm kev siv cov kev sim yooj yim hauv tsev. Cov duab hauv qab no feem ntau pom: hauv 2-3 lub hlis, cov kua txiv hmab txiv ntoo tshiab yuav hauv khw muag khoom qab zib. Vim li cas qhov no tshwm sim thiab crystallization cuam tshuam rau nws qhov zoo li cas? Beekeepers hu cov txheej txheem no "cage" thiab xav txog nws zoo heev. Txawm li cas los xij, tsis yog txhua yam "sab" nyob rau lub sijhawm, thiab qhov no ua rau cov neeg yuav khoom xav txog kev ntxhov siab.

Yuav tsum tau zib ntab tiag tiag?

Nrog rau lub sijhawm ntev, muv zib ntab crystallizes, qhov no tshwm sim dhau sijhawm txawm tias nyob rau hauv cov combs kaw hauv Hive.

Dab tsi yog vim li cas, nyob rau hauv tib lub sijhawm khaws cia, ib qho ntau yam tseem ua kua rau xyoo, thiab lwm yam zib ntab yog candied? Vim li cas qhov xwm txheej ntawm crystallization ntawm nws ntau hom sib txawv? Qhov no yog vim qhov sib piv ntawm cov khoom tseem ceeb: qabzib, dej thiab fructose hauv txhua yam.

Fructose dissolves zoo hauv dej thiab tsis tsim muaju. Qhov no txhais tau tias siab fructose zib mu(sage, heather, txiv ntseej) yuav tsis crystallize ntev. Acacia cov khoom muaj peev xwm nyob twj ywm ua kua rau ntau tshaj ob xyoos.

Glucose muaj qhov solubility tsawg tshaj plaws. Qhov ntau nws nyob rau hauv zib mu, qhov ceev nws "sets".

Qhov piv ntawm qabzib thiab fructose tsis yog tus nqi tas li. Nws nyob ntawm huab cua tej yam kev mob, hom zib mu nroj tsuag, breeds ntawm muv thiab cov degree ntawm kom loj hlob ntawm cov khoom ntawm lawv cov kev ua ub no tseem ceeb. Yog tias, nyob rau hauv kev cuam tshuam ntawm qee yam ntuj tsim, kev tso tawm ntawm fructose los ntawm cov nroj tsuag nce, ces cov zib ntab sau xyoo no yuav tsis crystallize, tshuav cov kua rau lub sijhawm ntev heev.

Lwm cov suab thaj uas muaj nyob rau hauv qhov delicacy kuj cuam tshuam cov txheej txheem crystallization.

Melecytosis yog ib qho tshuaj tiv thaiv crystallizer ntawm qabzib. Cov ntsiab lus qis ntawm cov ntsiab lus hais (2-3%) tuaj yeem pom nyob rau hauv ntau yam sau los ntawm rape, colza, sunflower. Lawv zaum nrawm dua, yog li nws yog qhov qub uas tom qab 2 lub hlis xws li zib ntab candied.

Vim li cas ho tsis honeydew zib mu crystallize? Nyob rau hauv lawv, nrog rau cov txiv ntseej, txiv qaub thiab dawb acacia ntau yam, feem pua ntawm melcytosis yog siab dua (6-9%). Cov khoom no nws tus kheej, ntawm cov ntsiab lus siab, tuaj yeem ua rau hauv daim ntawv ntawm flaky crystals.

Qhov zoo ntawm cov khoom, kev loj hlob thiab nws cov keeb kwm botanical tuaj yeem txiav txim los ntawm qhov xwm txheej ntawm crystallization thiab sai npaum li cas cov zib ntab candied.

Vim li cas ho tsis lim zib ntab?

Pollen nplej tam sim no nyob rau hauv cov khoom ntuj yog qhov chaw nyob ib puag ncigcov txheej txheem crystallization pib. Yog tias koj hla zib ntab los ntawm cov lim dej uas tshem tawm paj ntoos, hnoos qeev thiab cov tshuaj protein, nws tsis tawv rau lub sijhawm ntev thiab muaj kev nthuav qhia txaus nyiam. Tuam Tshoj thiab Is Nrias teb yog cov khoom lag luam loj rau cov teb chaws Europe. Lub hauv paus chiv keeb ntawm zib mu tsuas tuaj yeem taug qab los ntawm paj paj, thiab hauv qee lub tebchaws nws tseem txwv tsis pub hu cov khoom qab zib ultra-filtered lo lus "ziab".

zib ntab tiag tiag ua li cas?

Candied los yog tsis yog cov khoom uas muv tsim los ntawm syrup? Lawv

tsim cov khoom zoo sib xws hauv cov khoom siv tshuaj rau cov paj zib ntab ntuj. Cov txheej txheem nyob rau hauv nws coj qhov chaw raws nraim tib txoj kev, yog li nws tag nrho nyob ntawm lub conscientiousness ntawm beekeeper. Paub txog cov subtleties ntawm kev tsim khoom, koj tuaj yeem cuam tshuam nws qhov sib xws. Qab zib yog ib qho yooj yim kom ceev los ntawm kev ntxiv cov qub zib mu rau cov zib ntab tshiab. Los ntawm kev ntxiv 1 g ntawm shrunken zib mu rau 1 kg ntawm kua thiab sib tov kom huv si, koj tuaj yeem tau txais lub tawb hauv 1-2 hnub.

Cold candied sai dua. Nws pib ntawm ciam teb ntawm cov kua thiab cua; kua thiab khoom. Qee hom tawv nqaij los ntawm sab saum toj mus rau hauv qab, nyob rau hauv lwm tus neeg lub nucleated crystals poob mus rau hauv qab, thiab cov txheej txheem mus rau hauv qab mus rau sab saum toj.

Cov txheej txheem ntawm qab zib tsis cuam tshuam rau qhov zoo ntawm cov khoom thiab tsis txo nws cov khoom noj muaj txiaj ntsig. Thaum lub sij hawm Soviet Union, nws tau txwv tsis pub muag kua zib mu ntawm kev lag luam ua liaj ua teb tom qab Lub Kaum Hli 1, xav tias nws yog cuav thiab tsis haum rau kev noj.
