Anhydrous citric acid
Citric acid, tseem hu ua citric acid, muaj cov mis mos molecular ntawm C6H8O7.Nws yog ib qho tseem ceeb ntawm cov organic acid.Nws muaj cov xim tsis muaj xim, tsis muaj ntxhiab tsw, muaj lub zog qaub saj, yooj yim soluble hauv dej, thiab muaj qhov hnyav molecular ntawm 192.13.Anhydrous citric acid yog acidity Conditioners thiab zaub mov additives.
Ntuj citric acid yog dav faib nyob rau hauv cov xwm.Ntuj citric acid muaj nyob rau hauv cov pob txha, cov leeg thiab cov ntshav ntawm cov nroj tsuag xws li txiv qaub, citrus, pineapples thiab lwm yam txiv hmab txiv ntoo thiab tsiaj txhu.Synthetic citric acid yog tau los ntawm fermenting qab zib-muaj tshuaj xws li qab zib, molasses, starch, thiab grapes.
Kev siv citric acid
1. Kev lag luam zaub mov
Feem ntau yog siv los ua qaub tshuaj, solubilizer, tsis muaj, antioxidant, deodorant, tsw enhancer, gelling agent, toner, thiab lwm yam.
Nyob rau hauv cov nqe lus ntawm cov khoom noj additives, nws yog tsuas yog siv nyob rau hauv carbonated dej haus, kua txiv hmab txiv ntoo haus, lactic acid dej haus thiab lwm yam dej haus refreshing thiab pickled khoom.
(1) Ntxiv citric acid rau hauv cov kaus poom txiv hmab txiv ntoo tuaj yeem tswj tau lossis txhim kho qhov tsw ntawm cov txiv hmab txiv ntoo, ua kom cov kua qaub ntawm qee cov txiv hmab txiv ntoo nrog qis acidity thaum lawv ntim cov kaus poom, ua kom tsis muaj cua sov ntawm cov kab mob thiab inhibit lawv txoj kev loj hlob, thiab tiv thaiv cov txiv hmab txiv ntoo hauv kaus poom nrog qis dua. acidity.Cov kab mob o thiab kev puas tsuaj feem ntau tshwm sim.
(2) Ntxiv citric acid rau cov khoom qab zib raws li ib tug qaub neeg sawv cev yog ib qho yooj yim rau kev koom tes nrog fruity saj.
(3) Kev siv citric acid nyob rau hauv gel zaub mov jams thiab jelly tuaj yeem txo qhov tsis zoo ntawm pectin, kom cov intermolecular hydrogen bonds ntawm pectin tuaj yeem ua ke rau gel.
(4) Thaum ua cov zaub hauv kaus poom, qee cov zaub qhia cov tshuaj tiv thaiv alkaline.Siv citric acid raws li pH adjuster tsis tau tsuas yog ua lub luag hauj lwm seasoning, tab sis kuj tswj nws zoo.
2. Kev ntxuav hlau
Citric acid yog cov organic acid uas tsim los ntawm microbial fermentation thiab yog siv dav hauv cov tshuaj ntxuav tes.Lub corrosion inhibition kev ua tau zoo ntawm citric acid hauv detergents kuj tseem ceeb.Pickling yog ib feem tseem ceeb ntawm kev ntxuav tshuaj.Piv nrog rau cov inorganic acids, cov acidity ntawm citric acid kuj tsis muaj zog, yog li nws tsis haum rau txhua yam khoom siv.Cov corrosiveness uas tsim los kuj tseem me me, kev nyab xeeb thiab kev ntseeg siab ntawm citric acid ntxuav yog qhov muaj zog, thiab cov kua khib nyiab kuj yooj yim los daws, uas yuav tsis ua mob rau tib neeg lub cev.Nws tuaj yeem siv los ntxuav cov kav dej, cov khoom sib xyaw surfactants los ntxuav cov dej rhaub dej, cov tshuab ntxuav dej huv, thiab ua cov tshuaj ntxuav citric acid.
3. Kev lag luam tshuaj lom neeg zoo
Citric acid yog ib hom txiv hmab txiv ntoo acid.Nws lub luag haujlwm tseem ceeb yog txhawm rau ua kom rov ua dua keratin.Nws yog feem ntau siv rau hauv tshuaj pleev ib ce, tshuaj zawv plaub hau, tshuaj zawv plaub hau, tshuaj pleev ib ce, tshuaj pleev thaiv hnub, thiab cov khoom siv pob txuv.
Hauv kev siv tshuaj lom neeg, nws tuaj yeem siv los ua cov tshuaj reagent rau kev tshuaj xyuas tshuaj, ua ib qho kev sim reagent, chromatographic tsom xam reagent thiab biochemical reagent.
Citric acid tuaj yeem siv los ua cov dyeing tsis muaj formaldehyde thiab ua tiav tus neeg saib xyuas kom zoo inhibit qhov daj ntawm cov ntaub.
4. Sterilization thiab coagulation txheej txheem
Kev sib xyaw ua ke ntawm citric acid thiab kub 80 ° C muaj txiaj ntsig zoo ntawm kev tua cov kab mob spores, thiab tuaj yeem tua cov kab mob spores polluted nyob rau hauv cov kav dej ntawm lub tshuab hemodialysis.Citrate ions thiab calcium ions tuaj yeem tsim cov txheej txheem soluble uas nyuaj rau kev sib cais, yog li txo qhov concentration ntawm calcium ions hauv cov ntshav thiab cuam tshuam cov ntshav coagulation.
5. Tsiaj txhu
Citric acid yog tsim los ntawm carboxylation ntawm acetyl-CoA thiab oxaloacetate nyob rau hauv lub cev lub tricarboxylic acid voj voog, thiab koom nyob rau hauv lub metabolism ntawm qab zib, rog thiab protein nyob rau hauv lub cev.Ntxiv citric acid rau cov khoom noj sib xyaw tuaj yeem tua kab mob, tiv thaiv kab mob, thiab tiv thaiv salmonella thiab lwm yam kab mob ntawm tsiaj pub.Kev noj cov citric acid los ntawm cov tsiaj tuaj yeem txo qhov kev loj hlob ntawm cov kab mob thiab inhibit qhov tsim cov tshuaj lom metabolites, thiab txhim kho tsiaj kev ntxhov siab.
(1) Ua kom muaj kev noj zaub mov ntau ntxiv thiab txhawb kev zom zaub mov thiab nqus cov as-ham
Ntxiv citric acid rau kev noj haus tuaj yeem txhim kho lub palatability ntawm cov zaub mov thiab txhim khu lub qab los noj mov ntawm cov tsiaj, yog li ua rau tus tsiaj noj kom tsawg, txo cov pH ntawm cov zaub mov thiab txhawb kev zom cov as-ham.
(2) Txhawb kev noj qab haus huv ntawm plab hnyuv flora
Citric acid txo cov pH hauv plab hnyuv, thiab muab kev loj hlob zoo rau probiotics xws li cov kab mob lactic acid nyob rau hauv txoj hnyuv, yog li tswj kom muaj qhov sib npaug ntawm microbial flora hauv plab hnyuv ntawm cov tsiaj nyeg thiab nqaij qaib.
(3) Txhim kho lub cev muaj peev xwm tiv thaiv kev ntxhov siab thiab tiv thaiv kab mob
