DL-Malic Acid (CAS: 617-48-1) feem ntau yog siv hauv kev lag luam zaub mov thiab dej haus feem ntau ua rau cov txiv hmab txiv ntoo qaub.Nws tau dav siv los ua Khoom Noj Khoom Noj thiab Acidulat.
DL-Malic Acid (CAS: 617-48-1) yog lub luag haujlwm rau lub siab ua kom koj tau txais thaum koj tom rau qee yam txiv hmab txiv ntoo qaub xws li txiv apples, txiv hmab txiv ntoo, thiab cherries.Nws du, ntev tartness ua rau nws zoo meej zaub mov additive.Thaum malic acid cov khoom xyaw qib sib xyaw nrog lwm cov kua qaub, suab thaj, sweeteners, thiab seasonings, nws tuaj yeem ua rau muaj kev ntxim nyiam heev, tso cai rau cov khoom qab zib ntxiv, thiab tseem ua raws li cov khoom noj acidity regulator.
Kev siv kuj suav nrog cov khoom siv raw rau tshuaj, tshuaj pleev ib ce, kho hniav, tshuaj ntxuav hlau, buffers, coagulants hauv kev lag luam textile, thiab fluorescent whitening agents rau polyester fibers.
Cov khoom xyaw no cov khoom lag luam siv dav dav thiab tshwm sim los ntawm kev lag luam zaub mov thiab dej haus mus rau cov khoom tu tus kheej thiab lwm yam.Yog li ntawd, malic acid yog ib qho ntawm cov khoom noj khoom haus uas xav tau tshaj plaws hauv khw niaj hnub no.Lub palate ntawm malic acid yog ze rau cov kua txiv hmab txiv ntoo thiab muaj ib qho tshuaj tsw qab ntuj.Piv nrog rau citric acid, malic acid muaj ntau dua acidity (qaub saj yog 20% muaj zog tshaj citric acid), txo cov cua sov tso zis, softer saj (ntau dua buffering coefficient) thiab ntev lub sij hawm kaw.Kev puas tsuaj corrosion tsis muaj zog, thiab hnav ntawm cov hniav enamel yog me me, uas tsis ua rau lub qhov ncauj thiab cov hniav puas.Malic acid yog ib tiam tshiab ntawm cov zaub mov acidity, uas yog lub npe hu ua &ldquo nyob rau hauv lom thiab khoom noj khoom haus teb;Cov zaub mov zoo tshaj plaws acidity tus neeg sawv cev "Nws yog siv dav hauv ntau yam khoom noj, xws li cawv, dej haus, jam, zom cov pos hniav thiab lwm yam.Nws tau dhau los ua qhov thib peb cov zaub mov qaub tom qab citric acid thiab lactic acid.Nws yog ib qho ntawm feem ntau siv organic acids nyob rau hauv lub ntiaj teb no zaub mov kev lag luam.
