Citric Acid Anhydrous | 77-92-9 ib
Khoom Description
Citric acid yog cov organic acid tsis muaj zog. Nws yog ib tug natural preservative conservative thiab kuj yog siv los ntxiv ib tug acidic los yog qaub, saj rau cov zaub mov thiab dej qab zib. Hauv biochemistry, lub hauv paus conjugate ntawm citric acid, citrate, yog qhov tseem ceeb raws li qhov nruab nrab ntawm lub voj voog citric acid thiab yog li ntawd tshwm sim hauv cov metabolism ntawm txhua yam muaj sia.
Nws yog xim tsis muaj xim lossis dawb crystalline hmoov thiab feem ntau yog siv los ua acidulant, flavoring thiab preservative preservative hauv cov khoom noj thiab dej haus. Nws kuj yog siv los ua antioxidant, plasticizer thiab detergent, builder.
Siv nyob rau hauv cov zaub mov, dej haus industries raws li ib tug acidulous tus neeg saib xyuas, flavoring siv nyob rau hauv cov zaub mov, dej haus industries raws li ib tug acidulous neeg sawv cev, flavoring agent, thiab preservative, kuj siv nyob rau hauv detergent, hluav taws xob plating, thiab tshuaj industries raws li ib tug oxidation inhibitor, plasticizer, thiab lwm yam.
Citric acid yog cov organic acid pom ntau yam txiv hmab txiv ntoo thiab Acidity regulators zaub, tab sis nws yog feem ntau concentrated nyob rau hauv txiv qaub thiab txiv qaub. Nws yog ib qho tshuaj tiv thaiv ntuj thiab tseem siv los ntxiv cov kua qaub (kub) saj rau cov zaub mov thiab dej qab zib. Hauv biochemistry, nws yog ib qho tseem ceeb raws li qhov nruab nrab ntawm lub voj voog citric acid lossis Krebs lub voj voog (saib kab lus kawg) thiab yog li ntawd tshwm sim hauv cov metabolism ntawm yuav luag txhua yam muaj sia. Tshaj citric acid yog nkag tau yooj yim metabolized thiab tshem tawm ntawm lub cev. Citric acid yog ib qho antioxidant. Nws kuj yog siv los ua tus neeg saib xyuas ib puag ncig.
Function & Application
Rau kev lag luam khoom noj khoom haus Vim tias citric acid muaj me ntsis thiab qaub acidity, nws yog feem ntau siv nyob rau hauv kev tsim khoom ntawm ntau yam dej haus, dej qab zib, wines, candies, khoom noj txom ncauj, biscuits, kaus poom kua txiv, khoom noj siv mis thiab lwm yam. Nyob rau hauv kev ua lag luam ntawm tag nrho cov organic acids, citric acid kev lag luam feem ntau tshaj 70%, flavoring agents, kuj siv tau raws li antioxidants nyob rau hauv edible roj. Nyob rau tib lub sijhawm, txhim kho cov txiaj ntsig zoo ntawm cov zaub mov, txhim kho qab los noj mov thiab txhawb kev zom zaub mov thiab nqus cov calcium thiab phosphorus hauv lub cev. Anhydrous citric acid yog siv ntau hauv cov dej haus Cov ntsev ntawm citric acid xws li calcium citrate thiab ferric citrate yog cov fortifiers uas yuav tsum tau ntxiv cov calcium thiab hlau ions nyob rau hauv tej yam khoom noj.
