Nws nyob ua ntej hauv daim ntawv teev cov kua qaub pom hauv feem ntau cov txiv hmab txiv ntoo thiab txiv hmab txiv ntoo. Txawm hais tias nws lub npe, nws ua lub luag haujlwm tseem ceeb hauv kev hais kwv txhiaj tsis yog tsuas yog txiv qaub, txiv qaub thiab txiv kab ntxwv, tab sis kuj tseem muaj lwm cov txiv hmab txiv ntoo thiab txiv ntoo. Citric, malic thiab quinic acids suav txog li 90% ntawm acidity hauv txiv duaj thiab apricots.
Niaj hnub no, citric acid, nrog rau glycerin, qab zib, acetone thiab lwm yam tshuaj, yog cov khoom uas hu ua European Union. tej khoom lag luam - lawv yog cov tsim tawm kom tau raws li qhov xav tau ntawm lub ntiaj teb ua lag luam thiab hauv qhov ntau.
E330, E331 thiab E333 - raws li cov npe niaj hnub no koj tuaj yeem pom nws hauv ntau yam khoom noj.
Ib me ntsis ntawm keeb kwm
Thawj thawj zaug citric acid tau nyob rau xyoo 1784 los ntawm Swedish chemist thiab kws muag tshuaj Karl Scheele los ntawm unripe lemons.
Citric acid hauv peb lub teb chaws tau pib tsim kev lag luam hauv xyoo 1913. Rau qhov no tau siv calcium citrate.
Tom qab ntawd lub ntiaj teb ua tsov ua rog tau pib, thiab cov lag luam, tau poob lawv cov khoom lag luam hauv paus, raug yuam kom kaw. Lub sijhawm peb caug xyoo dhau los, kev npaj siab tau rov pib ua tiav cov kua txiv citric acid los ntawm kev muab nws rho tawm los ntawm cov nroj tsuag, thiab los ntawm kev zom cov suab thaj.
Citric acid zaub mov nplua nuj:
Cov yam ntxwv dav ntawm citric acid
Citric acid yog zaub mov qib acid. Lub hauv paus ntsiab lus ntawm citric acid, zoo li lwm yam khoom noj acids, yog zaub raw cov ntaub ntawv thiab cov khoom ntawm nws ua.
Qhov xwm, citric acid muaj nyob hauv cov nroj tsuag, ntau yam txiv hmab txiv ntoo, kua txiv. Cov saj ntawm cov txiv hmab txiv ntoo thiab cov txiv ntoo feem ntau yog tsim los ntawm kev sib xyaw ntawm citric acid nrog suab thaj thiab cov uas muaj ntxhiab.
Citric acid, nrog rau nws cov ntsev - citrates, yog cov kev tswj qhov tseem ceeb ntawm cov kua qaub ntawm cov zaub mov. Qhov kev ua ntawm citric acid thiab nws cov ntsev yog raws li lawv lub peev xwm chelate hlau.
Cov kua qaub nrog qab ntxiag, lub teeb saj; siv nyob rau hauv kev tsim khoom ntawm kev ua cov cheese, mayonnaise, ntses nyob hauv cov ntses, nrog rau cov khoom qab zib thiab margarines.
Ntau tshaj li ib lab tons ntawm citric acid tau tsim txhua xyoo los ntawm fermentation.
Txhua hnub yuav tsum tau txhaj rau citric acid
Ib pab pawg ntawm cov kws tshaj lij ntawm Cov Khoom Noj thiab Kev Ua Si Kev Ua Si ntawm Koom Haum Ntiaj Teb Kev Noj Qab Haus Huv tau tsim tsa ib hnub lees paub cov tshuaj citric acid rau tib neeg: 66-120 milligrams ib kilogram ntawm lub cev qhov hnyav.
Citric acid yuav tsum tsis txhob meej pem nrog ascorbic acid, uas yog vitamin C.
Qhov xav tau ntawm citric acid nce:
- nrog kev ua kom lub cev nce ntxiv;
- thaum lub cev nyob rau hauv qhov kev phem ntawm sab nraud;
- nrog kev ua kom pom ntawm lub txim ntawm kev ntxhov siab.
Qhov xav tau ntawm citric acid txo:
- thaum so;
- nrog ntau acidity ntawm pais plab kua txiv;
- nrog kev yaig ntawm cov hniav txha hniav laus.
Kev zom ntawm citric acid
Citric acid tau txais txiaj ntsig zoo los ntawm peb lub cev, uas yog vim li cas nws tau muaj koob meej thoob plaws ntiaj teb.
Cov khoom siv tseem ceeb ntawm citric acid thiab nws cov nyhuv rau ntawm lub cev
Cov kua qaub no tau txais txiaj ntsig zoo rau cov neeg muaj teeb meem lub raum. Nws ua rau qeeb ntawm pob zeb tsim thiab rhuav lub pob zeb me. Nws muaj cov khoom tiv thaiv; cov ntsiab lus siab dua hauv cov zis, lub cev zoo dua yog tiv thaiv los ntawm kev tsim cov qog lub raum tshiab.
Cov kua qaub no nyob hauv qhov chaw tshwj xeeb hauv cov txheej txheem zom zaub mov. Nws yog cov khoom lag luam nruab nrab qhov tseem ceeb hauv kev muab lub cev nrog lub zog. Cov kua qaub no muaj nyob hauv cov leeg nqaij, tso zis, ntshav, pob txha, hniav, plaub hau, thiab mis.
Sib cuam tshuam nrog lwm cov ntsiab
Cov kua qaub no pab txhawb kev nqus tau zoo ntawm lwm cov tshuaj. Piv txwv li, potassium, calcium thiab sodium.
Cov cim ntawm citric acid tsis txaus
Lub siab xav noj qee yam acidic hauv lub cev ua rau pom tias tsis muaj cov kua qaub hauv lub cev, suav nrog citric acid. Nrog rau lub caij nyoog tsis muaj cov organic acids, qhov chaw nyob sab hauv ntawm lub cev ua tau alkalized.
Cov cim ntawm tshaj citric acid
Ib qho dhau heev ntawm cov citric acid ua rau nce ntxiv hauv cov ntsiab lus ntawm cov calcium ions hauv cov ntshav. Ib qho dhau ntawm cov kua qaub hauv cov kua qaub tuaj yeem ua rau kub hnyiab rau cov xoos thiab lub plab thiab lub plab, thiab qhov no tuaj yeem ua rau mob, hnoos thiab ntuav.
Ntau dhau los ntawm kev siv cov citric acid tuaj yeem ua kev puas tsuaj rau hniav puas thiab kab mob hauv lub plab.
Qhov tseeb cuam tshuam rau cov ntsiab lus ntawm citric acid hauv lub cev
Citric acid nkag rau hauv peb lub cev nrog zaub mov. Nws tsis tsim tawm ntawm tus kheej lub cev.
Citric acid rau kev zoo nkauj thiab noj qab haus huv
Cov kua qaub no muaj qhov ua tau zoo rau saum tawv taub hau, nqaim qhov hws ua paug. Nws yog ib qho zoo ntxiv rau ntxiv cov kua roj citric acid rau cov kav dej kom muag nws kom huv ua ntej yaug koj lub taub hau. Nws yog qhov hloov zoo rau cov plaub hau yaug. Qhov piv rau nram qab no yuav tsum tau siv: ib me nyuam diav ntawm citric acid rau ib liter dej. Cov plaub hau yuav ua softer thiab ci, nws yuav yooj yim dua zuag.
