Izakhiwo zomzimba nezamakhemikhali ze-L-malic acid
I-Malic acid, eyaziwa nangokuthi i-2-hydroxysuccinic acid, inama-stereoisomers amabili ngenxa ye-asymmetric carbon athomu ku-molecule.Emvelweni, ikhona ngezinhlobo ezintathu, okuyi-D-malic acid, i-L-malic acid kanye nengxube yayo i-DL-malic acid.Ikristalu emhlophe noma i-crystalline powder, i-hygroscopicity eqinile, incibilika kalula emanzini ne-ethanol.Inokunambitheka okumuncu okumnandi.I-malic acid isetshenziswa kakhulu ezimbonini zokudla nezamakhemisi.
Ukusetshenziswa komkhiqizo we-L-malic acid
【Isetshenziswa】 Isetshenziswa ekwenzeni ama-esters;esetshenziswa kuma-complexing agents kanye nama-flavoring agents.Ngokwezinhlinzeko zezwe lami i-GB 2760-90, ingasetshenziswa kuzo zonke izinhlobo zokudla.Njenge-agent emuncu, ingasetshenziswa esikhundleni se-citric acid (cishe i-80%), ikakhulukazi i-jelly nokudla okusekelwe ezithelo.Lo mkhiqizo unomsebenzi wokugcina umbala wesithelo semvelo, futhi ungasetshenziswa njengosizo lokukhipha i-pectin, i-ejenti yokukhuthaza ukukhula kwemvubelo, ukwakha isoso yesoya engenasawoti kanye noviniga, ukuthuthukisa ukunambitheka kwamakhukhamba, kanye i-emulsion stabilizer ye-margarine, imayonnaise, njll.Isetshenziswa kabanzi kuma-preservatives ahlukahlukene, ama-seasonings nezinye izithasiselo ezihlanganisiwe.
(1) Imboni yokudla: Isetshenziselwa ukucubungula nokulungisa iziphuzo, amazolo, ijusi yezithelo, futhi ingasetshenziswa nasekukhiqizeni uswidi, ujamu, njll. Inemiphumela elwa namagciwane kanye ne-antiseptic ekudleni.Ingasetshenziswa futhi ukulungisa i-pH yokuvutshelwa iyogathi futhi isuse i-tartrate ekwenzeni iwayini.
(2) Imboni kagwayi: Okuphuma ku-malic acid (njengama-esters) kungathuthukisa ukunambitheka kukagwayi.
(3) Imboni yemithi: Zonke izinhlobo zamaphilisi neziraphu ezine-malic acid zingaba nokunambitheka kwezithelo, okuvumela ukumuncwa nokusabalala emzimbeni.
(4) Imboni yamakhemikhali yansuku zonke: I-ejenti enhle yokuhlanganisa ne-ester ejenti.Isetshenziselwa ukwakhiwa kwe-toothpaste, ukwakhiwa kwethebhulethi yokuhlanza amazinyo, ukwakhiwa kwephunga elimnandi, njll. Ingasetshenziswa futhi njengengxenye yesiqedaphunga nesihlanzi.
