I-Lactic Acid |598-82-3
IiNkcazo zeeMveliso
I-Lactic Acid yi-chemical compound edlala indima kwiinkqubo ezininzi ze-biochemical.Kwaziwa ngokuba yi-acid yobisi, i-chemical compound edlala indima kwiinkqubo ezininzi ze-biochemical.Kwizilwanyana, i-L-lactate isoloko iveliswa kwi-pyruvate nge-enzyme lactate dehydrogenase. (LDH) kwinkqubo yokuvutshelwa ngexesha le-metabolism eqhelekileyo kunye nokuzivocavoca.Ayinyuki ekugxininiseni kude kube umlinganiselo wemveliso ye-lactate idlula izinga lokususwa kwe-lactate elawulwa yizinto ezininzi ezibandakanya: abathuthi be-Monocarboxylate, ukugxininiswa kunye ne-isoform ye-LDH kunye nomthamo we-oxidative wezicubu.Ukuxinwa kwe-lactate yegazi ngokuqhelekileyo ku-1-2 mmol / L ekuphumleni, kodwa kunokunyuka ukuya kwi-20 mmol / L ngexesha lokuzikhandla okukhulu.Kwimizi-mveliso, i-Lactic Acid fermentation yenziwa yi-Lactobacillus bacteria, phakathi kwabanye.Ezi ntsholongwane zinokusebenza emlonyeni;Iasidi abayivelisayo ibangela ukubola kwamazinyo okubizwa ngokuba yicaries.Kwezamayeza, i-lactate yenye yezinto eziphambili zeRinger's lactate okanye isisombululo seRinger's lactated (iCompoundSodium Lactate okanye iHartmann's Solution e-UK).Olu lwelo lwe-intravenous luqulethe i-sodium kunye ne-potassium cations, kunye ne-lactate kunye ne-chloride anions, kwisisombululo esinamanzi adibeneyo ekugxininiseni ukuze kube yi-isotonic xa kuthelekiswa negazi lomntu.Ngokuqhelekileyo isetyenziselwa ukuvuselela ulwelo emva kokulahleka kwegazi ngenxa yokwenzakala, utyando, okanye ukwenzakala kokutsha.
Isicelo
1. I-lactic acid ine-antiseptic enamandla kunye ne-fresh-reeping effect.Ingasetyenziswa kwiwayini yeziqhamo, isiselo, inyama, ukutya, ukwenza ipastry, imifuno (umnquma, cucumber, iperile itswele) pickling kunye nokunkonkxa, processing ukutya, ukugcinwa iziqhamo, kunye nohlengahlengiso pH, bacteriostatic, ixesha elide kwishelufa, isinongo, ukugcina umbala. , kunye nomgangatho wemveliso;
2. Ngokubhekiselele kwi-seasoning, incasa emuncu ekhethekileyo ye-lactic acid inokunyusa incasa yokutya.Ukongeza inani elithile le-lactic acid kwiisaladi ezifana nesaladi, i-soy sauce kunye neviniga inokugcina uzinzo kunye nokhuseleko lwe-microorganisms kwimveliso ngelixa wenza i-taste mbilder;
3. Ngenxa ye-acidity encinci ye-lactic acid, inokusetyenziswa njenge-agent ekhethiweyo emuncu kwiziselo ezithambileyo kunye nejusi;
4. Xa kusenziwa ibhiya, ukongeza isixa esifanelekileyo se-lactic acid kunokulungelelanisa ixabiso le-pH ukukhuthaza i-saccharification, ukuququzelela ukuvutshelwa kwegwele, ukuphucula umgangatho webhiya, ukwandisa incasa yebhiya kunye nokwandisa ubomi beshelufu.Isetyenziselwa ukulungisa i-pH kutywala, i-sake kunye newayini yeziqhamo ukuthintela ukukhula kwebhaktheriya, ukunyusa i-asidi kunye nencasa ehlaziyayo.
5. I-asidi ye-lactic yendalo iyisithako sendalo sangaphakathi kwiimveliso zobisi.Inokunambitheka kweemveliso zobisi kunye nefuthe elihle lokuchasana ne-microbial.Isetyenziswe ngokubanzi ekudibaniseni i-yoghurt cheese, i-ayisikrimu kunye nokunye ukutya, kwaye ibe yinto ethandwayo yobisi olumuncu;
6. I-lactic acid powder yi-conditioner emuncu ngokuthe ngqo kwimveliso yesonka esiqhumayo.Iasidi yeLactic yiasidi yendalo enegwele, ngoko ke inokwenza isonka sibe sodwa.Iasidi yeLactic sisilawuli sencasa emuncu yendalo.Isetyenziselwa ukubhaka kunye nokubhaka kwisonka, iikeyiki, iibhiskithi kunye nokunye ukutya okubhakiweyo.Inokuphucula umgangatho wokutya kunye nokugcina umbala., yandisa ubomi beshelufu.
7. Ekubeni i-L-lactic acid iyinxalenye yendalo yolusu yendalo yokuthambisa, isetyenziswa ngokubanzi njengento yokuthambisa kwiimveliso ezininzi zokunakekelwa kwesikhumba.
