Kev piav qhia
Sodium citrate, yog cov xim tsis muaj xim lossis dawb crystalline hmoov khoom; Nws tsis muaj ntxhiab tsw, qab ntsev, thiab txias.Nws yuav plam nws cov dej siv lead ua ntawm 150 ° C thiab yuav decomposed ntawm qhov kub siab dua. Nws kuj muaj me ntsis deliquescence hauv huab cua ntub thiab muaj huab cua huab cua thaum huab cua kub. Nws yog soluble hauv dej thiab glycerol, tab sis insoluble hauv cawv thiab qee cov kuab tshuaj organic. Sodium citrate tsis muaj tshuaj lom, thiab muaj pH kho lub peev xwm thiab muaj kev ruaj ntseg zoo, thiab yog li siv tau hauv kev lag luam khoom noj.
Function thiab Application
Sodium citrate muaj qhov xav tau loj tshaj plaws thaum siv los ua zaub mov ntxiv; Raws li cov khoom noj khoom haus additives, nws yog tsuas yog siv los ua flavoring agents, buffers, emulsifiers, bulking agents, stabilizers thiab preservatives; Tsis tas li ntawd, kev sib xyaw ntawm sodium citrate thiab citric acid tuaj yeem siv ntau yam jams, jelly, kua txiv, dej qab zib, dej qab zib, khoom noj siv mis thiab pastries gelling agents, flavoring agents thiab khoom noj khoom haus. siv rau kev tsim cov tshuaj tiv thaiv kab mob; thiab siv los ua cov tshuaj detergent additives hauv kev lag luam teeb.
Kev ua tau zoo heev
1.Safe thiab nontoxic khoom; Txij li thaum cov khoom siv tseem ceeb rau kev npaj sodium citrate feem ntau yog los ntawm cov khoom noj, nws muaj kev nyab xeeb thiab txhim khu kev qha yam tsis muaj kev phom sij rau tib neeg kev noj qab haus huv. United Nations Khoom Noj thiab Kev Ua Liaj Ua Teb thiab Lub Koom Haum Saib Xyuas Kev Noj Qab Haus Huv Ntiaj Teb tsis muaj kev txwv rau nws cov khoom noj txhua hnub, uas txhais tau hais tias cov khoom no tuaj yeem suav tias yog zaub mov tsis muaj tshuaj lom.
2.Nws yog biodegradable. Tom qab ua rau lub dilution ntawm ntau cov dej, sodium citrate ib nrab hloov mus rau hauv citrate, uas coexists nrog sodium citrate nyob rau hauv tib lub cev. Citrate yog ib qho yooj yim rau kev lom zem degradation ntawm dej los ntawm kev ua ntawm oxygen, tshav kub, teeb, kab mob thiab microbes. Nws txoj kev decomposition feem ntau mus los ntawm aconitic acid, itaconic acid, citraconic acid anhydride kom hloov mus rau carbon dioxide thiab dej ntxiv.
3.Qhov muaj peev xwm ntawm kev sib sau ua ke nrog cov hlau ions. Sodium citrate muaj peev xwm ua tau zoo ntawm kev sib sau ua ke nrog qee cov hlau ions xws li Ca2+, Mg2+; rau lwm cov ions xws li Fe2+, nws kuj muaj peev xwm ua tau zoo.
4.Kev solubility zoo heev, thiab solubility nce nrog nce kub ntawm dej.
5.Nws muaj lub peev xwm zoo rau kev hloov kho pH thiab cov cuab yeej buffering zoo. Sodium citrate yog tsis muaj zog acid-muaj zog alkali ntsev; Thaum ua ke nrog citrate, lawv tuaj yeem tsim pH tsis muaj zog nrog kev sib raug zoo; Yog li ntawd, qhov no yog qhov tseem ceeb heev rau qee qhov xwm txheej uas nws tsis tsim nyog kom muaj kev hloov pauv loj ntawm pH tus nqi. Tsis tas li ntawd, sodium citrate kuj muaj qhov ua tau zoo retardation thiab stability.
