Malic Acid CAS: 6915-15-7 Wopanga Wogulitsa

Asidi ya Malic, HOOCCH(OH).CH2COOH, yomwe imadziwikanso kuti hydroxysuccinic acid, ndi chinthu cholimba chopanda mtundu. Chimasungunuka m'madzi ndi mowa. Asidi ya Malic imapezeka m'mitundu iwiri yogwira ntchito komanso yosakanikirana ndi racemic. Imagwiritsidwa ntchito mu zamankhwala ndipo imapezeka m'maapulo ndi zipatso zina. Isomer yopezeka mwachilengedwe ndi L-form yomwe imapezeka m'maapulo ndi zipatso ndi zomera zina zambiri. Asidi ya Malic ndi alpha hydroxy acid yachitatu yaying'ono kwambiri pankhani ya kukula kwa mamolekyu. Ngakhale imagwiritsidwa ntchito mu zinthu zambiri zodzikongoletsera, makamaka zomwe zimasonyeza kuchuluka kwa "asidi ya zipatso" ndipo nthawi zambiri zimapangidwa kuti zisakalamba, mosiyana ndi glycolic ndi lactic acids, ubwino wake pakhungu sunaphunziridwe kwambiri. Ena opanga zinthu amaona kuti ndi kovuta kugwira ntchito nayo, makamaka poyerekeza ndi ma AHA ena, ndipo ikhoza kukhala yokwiyitsa pang'ono. Siigwiritsidwa ntchito kawirikawiri ngati AHA yokhayo mu chinthu. Imapezeka mwachilengedwe m'maapulo. Asidi ya Malic imagwiritsidwa ntchito mu mankhwala ngati acidulant yogwiritsidwa ntchito nthawi zonse. Ili ndi kukoma pang'ono kwa apulo ndipo imagwiritsidwa ntchito ngati chokometsera kuti ibise kukoma kowawa ndikupereka kukoma kokoma. Malic acid imagwiritsidwanso ntchito m'malo mwa citric acid mu ufa wofewa, zotsukira pakamwa, ndi mapiritsi otsukira mano.
