Lactic Acid |598-82-3 : kuv
Khoom Description
Lactic Acid yog cov tshuaj lom neeg uas ua lub luag haujlwm hauv ntau cov txheej txheem biochemical.Kuj hu ua kua mis acid, yog cov tshuaj lom neeg uas ua lub luag haujlwm hauv ntau cov txheej txheem biochemical.Nyob hauv tsiaj, L-lactate yog tas li tsim los ntawm pyruvate los ntawm enzyme lactate dehydrogenase. (LDH) nyob rau hauv tus txheej txheem ntawm fermentation thaum lub sij hawm ib txwm metabolism thiab ce.Nws tsis nce nyob rau hauv concentration kom txog thaum tus nqi ntawm lactate ntau lawm tshaj tus nqi ntawm lactate tshem tawm uas yog tswj los ntawm ntau yam xws li: Monocarboxylate transporters, concentration thiab isoform ntawm LDH thiab oxidative muaj peev xwm ntawm cov ntaub so ntswg.Qhov siab ntawm cov ntshav lactate feem ntau yog 1-2 mmol / L thaum so, tab sis tuaj yeem nce mus rau ntau dua 20 mmol / L thaum lub zog hnyav.Kev lag luam, Lactic Acid fermentation yog ua los ntawm cov kab mob Lactobacillus, thiab lwm yam.Cov kab mob no tuaj yeem ua haujlwm hauv lub qhov ncauj;Cov kua qaub uas lawv tsim yog lub luag haujlwm rau cov hniav lwj hu ua caries.Hauv cov tshuaj, lactate yog ib qho tseem ceeb ntawm Ringer's lactate lossis lactated Ringer's tov (CompoundSodium Lactate lossis Hartmann's Solution hauv UK).Cov kua dej no muaj cov sodium thiab potassium cations, nrog lactate thiab chloride anions, nyob rau hauv kev daws nrog dej distilled hauv concentration thiaj li yuav isotonic piv rau tib neeg cov ntshav.Nws feem ntau yog siv rau cov kua dej resuscitation tom qab cov ntshav poob vim raug mob, phais, los yog raug mob kub hnyiab.
Daim ntawv thov
1. Lactic acid muaj zog antiseptic thiab cov nyhuv tshiab.Nws tuaj yeem siv rau hauv cov txiv hmab txiv ntoo, dej haus, nqaij, khoom noj, pastry ua, zaub (txiv ntseej, dib, pearl dos) pickling thiab canning, zaub mov ua, txiv hmab txiv ntoo cia, nrog kev hloov pH, bacteriostatic, lub neej ntev txee, seasoning, xim preservation. , thiab cov khoom zoo;
2. Nyob rau hauv cov nqe lus ntawm seasoning, lub cim qaub saj ntawm lactic acid yuav ua rau kom cov saj ntawm zaub mov.Ntxiv ib qho nyiaj ntawm lactic acid rau cov zaub xam lav xws li zaub xam lav, kua ntses thiab vinegar tuaj yeem tswj kev ruaj ntseg thiab kev nyab xeeb ntawm cov kab mob hauv cov khoom thaum ua rau lub saj me me;
3. Vim yog cov kua qaub me me ntawm lactic acid, nws tuaj yeem siv los ua tus neeg nyiam qaub rau cov dej qab zib thiab kua txiv hmab txiv ntoo;
4. Thaum brewing npias, ntxiv cov lactic acid kom tsim nyog tuaj yeem kho tus nqi pH los txhawb saccharification, pab cov poov xab fermentation, txhim kho npias zoo, ua kom npias tsw thiab ua kom lub neej ntev.Nws yog siv los kho pH hauv cawv, cawv thiab txiv hmab txiv ntoo los tiv thaiv kev loj hlob ntawm cov kab mob, txhim kho acidity thiab refreshing saj.
5. Tej yam ntuj tso lactic acid yog ib yam khoom muaj nyob rau hauv cov khoom siv mis nyuj.Nws muaj qhov saj ntawm cov khoom siv mis nyuj thiab cov nyhuv anti-microbial zoo.Nws tau siv dav hauv kev sib xyaw yogurt cheese, ice cream thiab lwm yam khoom noj, thiab tau dhau los ua tus neeg sawv cev nrov mis nyuj;
6. Lactic acid hmoov yog cov kua qaub ncaj qha rau kev tsim cov mov ci.Lactic acid yog lub ntuj fermented acid, yog li nws tuaj yeem ua rau lub khob cij tshwj xeeb.Lactic acid yog lub ntuj qaub saj regulator.Nws yog siv rau ci thiab ci hauv qhob cij, ncuav mog qab zib, biscuits thiab lwm yam khoom noj ci.Nws tuaj yeem txhim kho cov zaub mov zoo thiab tswj cov xim., ncua lub txee lub neej.
7. Txij li thaum L-lactic acid yog ib feem ntawm daim tawv nqaij ntawm lub hauv paus ntuj moisturizing yam, nws yog dav siv los ua ib tug moisturizer rau ntau yam khoom tu tawv nqaij.
