I-asidi ye-Malic isetyenziswa kakhulu kumashishini okutya kunye namayeza
Inkcazo
I-asidi ye-Malic isetyenziswa ngokuqhelekileyo ekulungiseleleni amayeza, ii-mordants kunye ne-agent e-tanning, kwaye iqhele ukusetyenziswa njenge-reagent yokusombulula iikhompawundi ezisisiseko ze-racemic. Kwakhona i-agent emuncu kwizongezo zokutya, ubumuncu bungcono kune-malic acid, i-lactic acid kunye nokunye. Iityuwa zayo ezininzi zineemveliso ezibalulekileyo. Ngokomzekelo, i-reagent ye-Fehling yenziwe nge-potassium sodium tartrate kwibhubhoratri ukuchonga amaqela asebenzayo e-aldehyde kwisakhiwo seemolekyuli eziphilayo. I-potassium kunye netyuwa yesodium ikwabizwa ngokuba yityuwa yeRochelle. I-crystals yayo i-polarized phantsi koxinzelelo ukuze ivelise ukuhluka okunokwenzeka (impembelelo ye-piezoelectric) kuzo zombini iziphelo zomhlaba, ezinokuthi zenziwe zibe zizinto ze-piezoelectric zomsakazo kunye nentambo yosasazo. Umamkeli kunye nokuthatha. Ngokwezonyango, i-potassium antimony tartrate (eyaziwa ngokuba yi-tartrate) isetyenziselwa ukunyanga isifo seschistosomiasis.

Isicelo
1. Kwishishini lokutya: ingasetyenziselwa ukulungiswa kunye ne-concoction yesiselo, i-liqueur, ijusi yeziqhamo kunye nokuveliswa kweelekese kunye ne-jam njl.
2. Kwishishini lecuba: i-malic acid derivative (efana ne-esters) inokuphucula ivumba lecuba.
3. Kwishishini lamayeza: iitrochi kunye nesiraphu edityaniswe ne-malic acid inencasa yesiqhamo kwaye inokwenza lula ukufunxwa kunye nokusasazwa kwazo emzimbeni.
4. Ushishino lweekhemikhali zemihla ngemihla: njenge-agent edibeneyo efanelekileyo, ingasetyenziselwa i-toothpaste formula, iifomyula ze-spice synthesis njalo njalo. Ingasetyenziswa njengezithako zokukhupha ivumba kunye nezokucoca. Njengesongezo sokutya, i-malic acid sisithako sokutya esiyimfuneko ekuboneleleni kwethu ukutya. Njengomnikezeli wezongezo zokutya kunye nomthengisi wezithako zokutya e-China, sinokukubonelela nge-malic ekumgangatho ophezulu.
