Inkcazo
I-sodium citrate, yikristale engenambala okanye imveliso yomgubo wekristale emhlophe; ayinavumba, incasa enetyuwa, kwaye ipholile.Iza kuphulukana namanzi ayo ayikristale kwi-150 °C kwaye iya kubola kumaqondo obushushu aphezulu nangaphezulu. Ikwanazo nobugwele obungephi kumoya omanzi kwaye inepropathi yemozulu kumoya oshushu. Inyibilika emanzini nakwi-glycerol, kodwa ayinyibiliki etywaleni nakwezinye izinyibilikisi eziphilayo. I-sodium citrate ayinayo i-toxic effect, kwaye inamandla okulungelelanisa i-pH kunye nokuzinza okulungileyo, kwaye ngoko ingasetyenziselwa kwishishini lokutya.
Umsebenzi kunye neSicelo
I-sodium citrate inesidingo esikhulu xa isetyenziswa njengesongezo sokutya; Njengezongezo zokutya, isetyenziswa ikakhulu njengezinto zokunambitha, ii-buffers, i-emulsifiers, i-bulking agents, i-stabilizers kunye ne-preservatives; Ukongeza, ukudibanisa phakathi kwe-sodium citrate kunye ne-citric acid ingasetyenziselwa kwiintlobo ezahlukeneyo zejam, i-jelly, ijusi, iziphuzo, iziphuzo ezibandayo, iimveliso zobisi kunye ne-pastries gelling agents, i-flavoring agents kunye nezongezelelo zesondlo. esetyenziselwa ukwenza amayeza okulwa namahlwili; kwaye isetyenziswe njengezongezo zokucoca kwishishini lokukhanya.
Ukusebenza okugqwesileyo
1.Iipropati ezikhuselekileyo nezingenatyhefu; Ekubeni izinto ezisisiseko zokulungiswa kwe-sodium citrate zivela ikakhulu ekutyeni, zikhuselekile ngokupheleleyo kwaye zithembekile ngaphandle kokwenza ingozi kwimpilo yabantu. Ukutya kweZizwe eziManyeneyo kunye nezoLimo kunye noMbutho wezeMpilo weHlabathi awunamthintelo ekutyeni kwayo imihla ngemihla, oku kuthetha ukuba le mveliso inokuthathwa njengokutya okungenatyhefu.
2.Iyakwazi ukubola. Emva kokuxhomekeka kwi-dilution yamanzi amaninzi, i-sodium citrate iguqulwa ngokuyinxenye ibe yi-citrate, ehambelana ne-sodium citrate kwinkqubo efanayo. I-Citrate kulula ukujongana nokuthotywa kwebhayoloji emanzini ngesenzo seoksijini, ubushushu, ukukhanya, iibhaktheriya kunye ne-microbes. Iindlela zayo zokubola zihamba ngokubanzi nge-aconitic acid, i-itaconic acid, i-citraconic acid anhydride ukuze iguqulwe ngakumbi kwi-carbon dioxide kunye namanzi.
3.Ikhono lokwenza izinto ezinzima kunye neeoni zetsimbi. I-sodium citrate inamandla okwenza izinto eziyinkimbinkimbi kunye nezinye ioni zetsimbi ezifana neCa2 +, Mg2 +; kwezinye iiyoni ezifana ne-Fe2+, nayo inekhono elihle lokubumba.
I-4.I-solubility egqwesileyo, kunye ne-solubility yanda ngokunyuka kobushushu bamanzi.
I-5.Inamandla okulungelelaniswa kwe-pH kunye nepropathi efanelekileyo ye-buffering. I-sodium citrate yityuwa yealkali ene-asidi ebuthathaka; Xa zidibene ne-citrate, zinokwenza i-pH buffer kunye nokuhambelana okuqinileyo; ngoko ke, oku kuluncedo kakhulu kwezinye iimeko apho kungafanelekanga ukuba kubekho utshintsho olukhulu lwexabiso le-pH. Ukongeza, i-citrate ye-sodium nayo inomsebenzi oncomekayo wokulibaziseka kunye nokuzinza.
