Kev Siv
DL - Tartaric Acid yog ib qho tshuaj sib xyaw ua ke uas siv tau ntau yam. Nws siv dav hauv kev lag luam khoom noj thiab dej haus ua ib qho acidulant, flavor enhancer, thiab pH regulator. Nws tuaj yeem muab ib qho saj qaub thiab txhim kho qhov saj ntawm cov khoom xws li dej qab zib, kua txiv hmab txiv ntoo, thiab khoom qab zib. Hauv kev lag luam tshuaj, nws yog siv rau hauv kev tsim cov tshuaj thiab ua ib qho chiral resolving agent. Tsis tas li ntawd, DL - Tartaric Acid pom daim ntawv thov hauv kev lag luam tshuaj rau kev tsim cov esters thiab lwm yam organic compounds. Nws kuj tseem siv rau hauv qee cov khoom siv pleev kom zoo nkauj thiab khoom siv tu tus kheej los kho pH thiab txhim kho kev ruaj khov ntawm cov formulations.
