Malic acid tuaj yeem ua hauv ob txoj kev tseem ceeb: ntuj extraction thiab tshuaj schtesis. Cov kev tshem tawm tau tsuas yog huv yog ntxuav los ntawm txiv apples thiab lwm cov txiv hmab txiv ntoo, thaum cov khoom siv hluav taws xob yog tau los ntawm cov tshuaj organic yooj yim los ntawm cov txheej txheem hluavtaws.
Thaum raug rau malic acid, sib chwv nrog tawv nqaij thiab qhov muag yuav tsum tau zam thiab saib xyuas kom siv cov hnab looj tes tiv thaiv tus kheej xws li hnab looj tes thiab gloggles. Thaum siv thiab cia, sib cuag nrog cov tshuaj organic, oxidizing cov neeg sawv cev thiab cov muaj zog acids uas muaj zog yuav tsum zam rau kev tiv thaiv tsis muaj kev nyab xeeb ntawm kev tshwm sim. Ua ntej siv nws, cov lus qhia kev nyab xeeb txog kev nyab xeeb thiab kev ua haujlwm yuav tsum ua tib zoo nyeem thiab ua raws.

Kev siv
Nws tuaj yeem tsim cov chelates nrog hlau ions thiab tuaj yeem siv los tshem tawm cov khoom lag luam hlau (xeb). Nws tuaj yeem siv ib leeg lossis ua ke nrog lwm cov organic acids ua hlau tshuab nqus tsev.
DL-malic acid yog cov tshuaj ntsuab qib ntsev ntawm nws. Nws yog siv los ua tshuaj tua kab mob thiab tswj cov kab mob kab lis kev cai. DL-malic acid tua gram-zoo cov kab mob zoo li streptococcus pneumoniae thiab staphylococcus aureus. Nws tuaj yeem ua haujlwm los ntawm kev siv cov enzymes hauv cov kab mob no. Nws kuj nres qog hauv cov tsiaj.
