Incazelo
I-sodium citrate, iyikristalu engenambala noma umkhiqizo we-crystalline powder omhlophe;alinuki, alinambitheki elisawoti, futhi lipholile.Izolahlekelwa amanzi ayo ayikristalu ku-150 °C futhi izobola ngezinga lokushisa eliphakeme nakakhulu.Iphinde ibe nobumnandi obuncane emoyeni omanzi futhi inesimo sezulu esishisayo emoyeni oshisayo.Iyancibilika emanzini nakwi-glycerol, kodwa ayincibiliki otshwaleni nakwezinye izinyibilikisi zemvelo.I-sodium citrate ayinawo umthelela onobuthi, futhi inamandla okulungisa i-pH kanye nokuba nokuzinza okuhle, ngakho-ke ingasetshenziswa embonini yokudla.
Umsebenzi kanye nesicelo
I-sodium citrate inesidingo esikhulu kunazo zonke lapho isetshenziswa njengesengezo sokudla;Njengezithasiselo zokudla, isetshenziswa kakhulu njengama-flavour agents, ama-buffers, ama-emulsifiers, ama-bulking agents, ama-stabilizers nama-preservatives;ngaphezu kwalokho, inhlanganisela phakathi kwe-sodium citrate ne-citric acid ingasetshenziswa ezinhlobonhlobo zojamu, i-jelly, ijusi, iziphuzo, iziphuzo ezibandayo, imikhiqizo yobisi kanye nama-agent okugcoba amakhekhe, ama-flavoring agents kanye nezithako zokudla okunomsoco. esetshenziselwa ukukhiqizwa kwezidakamizwa ezilwa namahlule;futhi isetshenziswe njengezithasiselo zokuhlanza embonini yokukhanya.
Ukusebenza okuhle kakhulu
1.Izindawo eziphephile nezingenabo ubuthi;Njengoba izinto zokusetshenziswa eziyisisekelo zokulungiswa kwe-sodium citrate ikakhulukazi zivela ekudleni, kuphephe ngokuphelele futhi kuthembekile ngaphandle kokulimaza impilo yomuntu.I-United Nations Food and Agriculture kanye ne-World Health Organization ayinakho umkhawulo ekuthathweni kwayo kwansuku zonke, okusho ukuthi lo mkhiqizo ungathathwa njengokudla okungenabuthi.
2.I-biodegradable.Ngemva kokungena ngaphansi kokuhlanjululwa kwamanzi amaningi, i-sodium citrate iguqulwa kancane ibe yi-citrate, ehambisana ne-sodium citrate ohlelweni olufanayo.I-Citrate kulula ukuba ngaphansi kokuwohloka kwezinto eziphilayo emanzini ngenxa yesenzo somoya-mpilo, ukushisa, ukukhanya, amagciwane kanye namagciwane.Izindlela zayo zokubola ngokuvamile zidlula ku-aconitic acid, i-itaconic acid, i-citraconic acid anhydride ezophinde iguqulelwe ku-carbon dioxide namanzi.
3.Ikhono lokwenza inkimbinkimbi ngama-ion ensimbi.I-sodium citrate inamandla amahle okwenza inkimbinkimbi namanye ama-ion ensimbi afana ne-Ca2+, Mg2+;kwamanye ama-ion afana ne-Fe2+, futhi inekhono elihle lokwakha inkimbinkimbi.
I-4.I-solubility enhle kakhulu, futhi ukuncibilika kuyanda ngokukhuphuka kwezinga lokushisa lamanzi.
5.Inamandla amahle okulungisa i-pH kanye nesakhiwo esihle sokubhafa.I-sodium citrate ingusawoti we-alkali obuthakathaka oqinile we-asidi;Uma zihlanganiswa ne-citrate, zingakha isigcina se-pH esihambisana ngokuqinile;ngakho-ke, lokhu kuwusizo kakhulu kwezinye izimo lapho kungafanelekile ukuba noshintsho olukhulu lwenani le-pH.Ngaphezu kwalokho, i-sodium citrate nayo inokusebenza okuhle kakhulu kokubambezeleka nokuzinza.
