Synthetically, nws yog feem ntau ua los ntawm pob kws los ntawm fermentation. Lub ntiaj teb kev hloov pauv ntau dua 1.5 lab tons - yuav luag ib nrab ntawm cov ntim no tau tsim tawm hauv Suav teb. Cov khoom lag luam nrov tshaj plaws hauv kev lag luam khoom noj khoom haus, zoo li cov khoom ntxiv E330-E333, ua lub luag haujlwm ntawm kev tswj hwm acidity thiab khaws cia. Nws feem ntau yog siv rau kev tsim khoom ntawm cov cheese ua cov curds, ntau yam dej qab zib thiab sib xyaw qhuav rau lawv cov kev npaj. Citric acid belongs rau cov tshuaj ntxiv uas tsis muaj kev puas tsuaj thiab tau tso cai rau siv tsis tas siv. Hauv tsev, nws yog siv feem ntau rau kev txuag.

Alchemist Jabir ibn Hayyan tau txiav txim siab los ua tus tshawb pom ntawm citric acid, tab sis thawj tus uas tuaj yeem cais cov tshuaj yog tus kws muag tshuaj los ntawm Sweden - Karl Scheele. Qhov kawg ntawm lub xyoo pua 18th, siv cov tshuaj tiv thaiv nag lossis daus, nws tau txais cov kua qaub los ntawm kua txiv qaub hauv daim ntawv ntawm calcium citrate. Txawm li cas los xij, hauv nws daim ntawv dawb huv, nws twb muaj peev xwm cais nws los ntawm citrate tsuas yog tom qab yuav luag ib puas xyoo.

Tom qab kev txhim kho kev lag luam ntawm cov khoom pib, pib nws tau ua ncaj qha los ntawm kua txiv qaub. Qhov kawg tau ua ke nrog nrawm, raws li qhov tshwm sim ntawm cov calcium citrate tau nag lossis daus, uas tau ua tiav ntxiv, thiab vim li ntawd, tau txais citric acid.

Tab sis qhov kawg ntawm lub xyoo pua puv 19, txoj hauv kev kom tau txais cov khoom lag luam los ntawm kev fermentation tau pom hauv tebchaws Yelemes, uas tau siv cov kab mob hu ua penicillus genus. Tau ntev, txawm li cas los xij, txoj hauv kev no tsis tuaj yeem siv tau, txij li cov txheej txheem rau kev ua kom huv cov khoom kawg tsis tau debugged, tab sis xyoo 1919 txhua qhov teeb meem thaum kawg tau daws.

Qhov no tau txais txiaj ntsig zoo, txij li qhov kev thov rau cov khoom lag luam tau loj hlob ntawm qhov nrawm thiab qhov yooj yim dua cov txheej txheem enzymatic tau qhib txoj hauv kev tshiab rau kev lag luam. Txog rau hnub no, citric acid tau txais los ntawm cov khoom lag luam carbohydrate, uas tau fermented los ntawm cov pwm Aspergillus niger.

Cov khoom qub yog txawv nyob ntawm thaj av. Yog li, hauv Asmeskas thiab Europe, cov khoom tau txais los ntawm hydrolyzate ntawm pob kws, hauv Asia - los ntawm hydrolyzate ntawm cov qos yaj ywm thiab qos yaj ywm qab zib, crystalline sucrose, zib ntab (kua txiv hmab txiv ntoo yog cov khoom tsim los ntawm cov piam thaj), thiab ntau yam ua liaj ua teb pov tseg. kuj tseem siv ntau zaus.

Cov mis ntawm cov tshuaj yog HOOC-CH2-C (OH) COOH-CH2-COOH lossis (HOOCCH2) 2C (OH) COOH. Cov tshuaj muaj pes tsawg leeg ntawm citric acid yog ib qho hydroxyl thiab peb pawg carboxyl, vim li no nws thiaj hu ua tribasic carboxylic acid.

Cov ntsiab lus calorie ntawm citric acid yog 0 kcal, nws tsis sawv cev rau cov zaub mov muaj txiaj ntsig, tab sis ua lub luag haujlwm tseem ceeb hauv kev tshuaj lom neeg hauv tib neeg lub cev.

  • Alkalinization ntawm lub cev … Nws tau paub tias qee qhov qib pH tsis tu ncua yuav tsum tau khaws cia hauv peb lub cev, txawm li cas los xij, kev noj zaub mov ib txwm muaj nrog cov khoom tsiaj muaj ntau thiab tsis muaj zaub tuaj yeem ua rau acidosis - acidification ntawm lub cev, uas ua rau muaj kev txhim kho ntawm ntau yam kab mob loj. Citric acid yog ib qho ntawm cov khoom lag luam uas hloov pauv cov kua qaub-puag sib npaug ntawm alkalization.
  • Cov nyhuv diuretic … Cov khoom muaj cov nyhuv diuretic me me, tso cai rau koj tshem tawm cov kua ntau dhau los ntawm lub cev, thiab tiv thaiv kev o.
  • Cov nyhuv antioxidant … Tsis tas li, cov khoom yog cov tshuaj tiv thaiv kab mob uas tiv taus cov dawb radicals. Cov tom kawg tau tsim nyob hauv peb lub cev nyob rau hauv kev cuam tshuam ntawm kev noj zaub mov tsis zoo, huab cua tsis zoo, kev siv tshuaj lom neeg hauv tsev, thiab lwm yam. Cov dawb radicals sau rau hauv lub cev ntau ntau thiab tawm tsam cov hlwb ntawm peb lub cev. Antioxidants, ntawm qhov tod tes, tuaj yeem siv lub tshuab thiab tshem tawm qhov kev tawm tsam.
