Malic acid amagwiritsidwa ntchito makamaka m'mafakitale azakudya komanso azamankhwala
Kufotokozera
Malic acid amagwiritsidwa ntchito kwambiri popanga mankhwala, ma mordants ndi zofufutira, ndipo amagwiritsidwanso ntchito ngati reagent pakuthana ndi mankhwala oyambira a racemic. Komanso ndi wowawasa wothandizila zakudya zina, wowawasa bwino kuposa malic acid, lactic acid ndi zina zotero. Mchere wambiri umagwira ntchito yofunika kwambiri. Mwachitsanzo, Fehling reagent amapangidwa ndi potassium sodium tartrate mu labotale kuzindikira aldehyde zinchito magulu mu kapangidwe ka organic mamolekyu. Mchere wake wa potaziyamu ndi sodium umatchedwanso mchere wa Rochelle. Makhiristo ake amapangidwa polarized pansi pa kukakamizidwa kuti apange kusiyana komwe kungatheke (piezoelectric effect) pamapeto onse a pamwamba, omwe angapangidwe kukhala zinthu za piezoelectric zowulutsira wailesi ndi chingwe. Wolandira ndi kunyamula. Zamankhwala, potaziyamu antimony tartrate (yomwe imadziwika kuti tartrate) imagwiritsidwa ntchito pochiza likodzo.

Kugwiritsa ntchito
1. M'makampani a chakudya: angagwiritsidwe ntchito pokonza ndi kusakaniza chakumwa, mowa, madzi a zipatso ndi kupanga maswiti ndi kupanikizana ndi zina zotero. Zimakhalanso ndi zotsatira za kulepheretsa mabakiteriya ndi antisepsis ndipo zimatha kuchotsa tartrate panthawi yopangira vinyo.
2. M'makampani a fodya: zotumphukira za malic acid (monga esters) zimatha kuwonjezera kununkhira kwa fodya.
3. M'makampani opanga mankhwala: ma troche ndi manyuchi ophatikizidwa ndi asidi a malic amakhala ndi kukoma kwa zipatso ndipo amatha kuwongolera kuyamwa kwawo ndikufalikira m'thupi.
4. Makampani opanga mankhwala a tsiku ndi tsiku: monga wothandizira bwino, amatha kugwiritsidwa ntchito popanga mankhwala otsukira mano, mankhwala opangira zonunkhira ndi zina zotero. Itha kugwiritsidwanso ntchito ngati zopangira deodorant ndi detergent. Monga chowonjezera cha chakudya, malic acid ndi gawo lofunikira pazakudya zathu. Monga otsogola pazowonjezera zakudya komanso zopangira zakudya ku China, titha kukupatsirani malic apamwamba kwambiri.
