Nyob ntawm lub rhawv ntawm cov khw niaj hnub no koj tuaj yeem pom tsis tau tsuas yog pas nrig, tab sis kuj beet qab zib. Cov khoom qab zib no tau pom dav siv hauv kev ua noj. Nws yog siv los npaj ntau yam tais diav. Tom qab nyeem ntawv hnub no, koj yuav kawm txog cov txiaj ntsig zoo thiab cov yam ntxwv ntawm kev tsim cov khoom no.

Brief keeb kwm yav dhau

Tus Fab Kis botanist Olivier de Serres ua thawj qhov kev sim ua kom pom tseeb rau qhov siab ntawm qab zib hauv beets. Hmoov tsis zoo, tom qab ntawd nws cov yeeb yam tsis tau ua tiav nrog kev vam meej thiab tsis txhawb kev txaus siab ntawm ntau tus neeg. Thiab tsuas yog ntau xyoo tom qab, xyoo 1747, German chemist Markgraf tswj kom tau cov khoom qab zib beet. Nws tshaj tawm qhov kev tshawb pom no thaum nws hais lus tsis tu ncua, tab sis nws txoj haujlwm raug tso tseg yam tsis muaj kev saib xyuas.

Tsuas yog xyoo 1786, nws txoj haujlwm tau txuas ntxiv los ntawm Fab Kis Fab Kis Charles Achard. Lub luag haujlwm tseem ceeb ntawm nws qhov kev sim ua liaj ua teb, ua rau ntawm thaj av me me ze Berlin, yog nrhiav ntau yam zoo tshaj plaws.beets, optimally suited rau zus tau tej cov suab thaj. Peb xyoos tom qab, cov txiaj ntsig ntawm nws txoj kev tshawb fawb tau nthuav tawm rau tus huab tais Prussian. Thiab nyob rau hauv 1802, thawj lub Hoobkas rau kev tsim cov khoom no tau qhib.

Composition

Nws yuav tsum tau muab sau tseg tias beet qab zib tsis muaj dab tsi tab sis zoo tib yam sucrose. Thaum nws nkag mus rau tib neeg lub cev, nws tam sim ntawd tawg mus rau hauv qabzib thiab fructose. Tom qab ntawd, cov tshuaj no tau nkag mus rau hauv cov ntshav thiab xa mus rau txhua lub cell, muab lub zog rau lawv.

Vim qhov siab ntawm kev tawg mus rau hauv ib tus neeg cov khoom, qab zib yog ib qho yooj yim digestible carbohydrate. Lub zog tus nqi ntawm ib puas grams ntawm cov khoom yog 390 kilocalories.

khoom muaj txiaj ntsig

Rau cov neeg uas tsis paub cov xim uas tsis muaj qab zib beet yog dab tsi, nws yuav nthuav tias cov khoom no xyaum tsis noj. Ua ntej, nws dhau mus rau theem purification, ua tsaug uas peb tau txais yam peb pom ntawm lub txee ntawm peb lub khw. Cov khoom ua kom zoo yog hais txog cov carbohydrates, uas yog cov khoom noj muaj txiaj ntsig zoo uas ua rau peb lub cev muaj zog nrog lub zog tseem ceeb. Sucrose, tawg sai sai hauv lub plab zom mov ua ob yam khoom, nkag mus rau hauv cov hlab ntsha thiab kis mus rau txhua lub cev thiab cov ntaub so ntswg.

Glucose muab cov nqi zog ntau. Tsis tas li ntawd, nws txhawb nqa kev ua haujlwm ntawm lub siab. Yog li ntawd, nws yog feem ntau pom zoo kom muab nws intravenously rau tshuaj lom thiab lwm yamteeb meem kev noj qab haus huv. Tsis tas li ntawd, beet qab zib tau ntse siv hauv tshuaj. Nws yog siv los tsim cov syrups, uas yog lub hauv paus rau kev tsim cov tshuaj ua kua.

khoom txaus ntshai

Qab Zib muaj ntau cov calories khoob uas tuaj yeem tau los ntawm lwm qhov chaw. Tsis zoo li cov xuab zeb qab zib no, cov vitamins thiab cov zaub mov muaj nyob hauv lwm cov khoom.

Nws yuav tsum tsis txhob hnov qab tias beet qab zib, noj ntau yam tsis tsim nyog, yog qhov phem rau cov hniav. Qhov no yog vim lub fact tias muaj ntau cov kab mob nyob rau hauv tib neeg lub qhov ncauj kab noj hniav, nyob rau hauv tus ntawm cov khoom no yog hloov dua siab tshiab rau hauv acids uas rhuav tshem enamel thiab pab rau caries.

Tsev tsim khoom

Peb nco ntsoov tam sim ntawd tias cov suab thaj uas tsis tau ua tiav yog tsim los ntawm cov qoob loo sib raug. Cov khoom siv raw rau nws cov khoom yog cov khoom puas tsuaj, yog li cov nroj tsuag ua haujlwm tau tsim nyob rau thaj tsam tam sim ntawm cov nroj tsuag. Kev tsim technology muaj ntau theem. Nws suav nrog kev rho tawm, purification, evaporation thiab crystallization.

Cov beets ntxuav ua ntej raug txiav rau hauv me me thiab xa mus rau diffuser. Nws rho cov suab thaj los ntawm cov nroj tsuag loj siv dej kub. Raws li cov txheej txheem no, kua txiv tau txais, muaj 15% sucrose. Qhov seem pov tseg (beet pulp) tuaj yeem siv raupub tsiaj ua liaj ua teb. Tom qab ntawd, cov kua txiv diffusion yog pub rau hauv lub saturator. Nyob ntawd nws ua ke nrog txiv qaub kua txiv. Qhov no yog tsim nyog los cais hnyav impurities uas nyob rau hauv qab. Cov tshuaj rhuab yog ces kho nrog carbon dioxide thiab lim. Qhov tshwm sim yog lub thiaj li hu ua kua txiv hmab txiv ntoo, uas muaj 50-65% qab zib.

Cov kua uas tau tshwm sim tau raug crystallization, nqa tawm hauv lub tshuab nqus tsev loj. Qhov tshwm sim ntawm tus txheej txheem no yog ib tug massecuite. Nws yog molasses tov nrog sucrose crystals. Txhawm rau cais cov khoom no, cov khoom no raug rau centrifugation. Qab zib tau nyob rau hauv txoj kev no tsis xav tau ntxiv refining. Nws yog recyclable tag nrho.

Cov kua nplaum uas seem raug xa mus rau evaporation, uas ua rau cov crystals tsawg dua, uas tom qab ntawd yaj thiab ua kom zoo.
