Thupi ndi mankhwala katundu wa L-malic acid
Malic acid, omwe amadziwikanso kuti 2-hydroxysuccinic acid, ali ndi ma stereoisomers awiri chifukwa cha atomu ya carbon asymmetric mu molekyulu.M'chilengedwe, ilipo m'mitundu itatu, yomwe ndi D-malic acid, L-malic acid ndi osakaniza ake DL-malic acid.White crystal kapena crystalline ufa, wamphamvu hygroscopicity, mosavuta sungunuka m'madzi ndi Mowa.Ali ndi kukoma kosangalatsa kowawasa.Malic acid amagwiritsidwa ntchito makamaka m'mafakitale azakudya ndi zamankhwala.
Kugwiritsa ntchito L-malic acid
【Magwiritsidwe】 Amagwiritsidwa ntchito popanga ma esters;amagwiritsidwa ntchito mu complexing agents ndi flavoring agents.Malinga ndi zomwe dziko langa GB 2760-90, angagwiritsidwe ntchito mitundu yonse ya chakudya.Monga wothandizira wowawasa, angagwiritsidwe ntchito m'malo mwa citric acid (pafupifupi 80%), makamaka pa zakudya za jelly ndi zipatso.Izi zimakhala ndi ntchito yosunga mtundu wa zipatso zachilengedwe, komanso zitha kugwiritsidwa ntchito ngati chothandizira pochotsa pectin, wothandizira kulimbikitsa kukula kwa yisiti, kupanga msuzi wa soya wopanda mchere ndi viniga, kukonza kukoma kwa pickles, ndi emulsion stabilizer kwa margarine, mayonesi, etc.Amagwiritsidwa ntchito kwambiri muzosungirako zosiyanasiyana, zokometsera ndi zina zowonjezera.
(1) Makampani opanga zakudya: Amagwiritsidwa ntchito popanga ndi kukonza zakumwa, mame, madzi a zipatso, komanso angagwiritsidwe ntchito popanga maswiti, kupanikizana, ndi zina zotero. Ali ndi mphamvu zowononga tizilombo toyambitsa matenda pa chakudya.Itha kugwiritsidwanso ntchito kusintha pH ya fermentation ya yoghurt ndikuchotsa tartrate pakupanga vinyo.
(2) Makampani a fodya: Zochokera ku Malic acid (monga esters) zimatha kusintha kukoma kwa fodya.
(3) Makampani opanga mankhwala: Mitundu yonse ya mapiritsi ndi ma syrups okhala ndi malic acid amatha kukhala ndi kukoma kwa zipatso, komwe kumathandizira kuyamwa ndi kufalikira m'thupi.
(4) Makampani opanga mankhwala atsiku ndi tsiku: Ndiwothandizira bwino komanso opangira ester.Amagwiritsidwa ntchito popanga mankhwala otsukira mano, kupanga mapiritsi otsuka mano, kupanga fungo lonunkhira, etc. Angagwiritsidwenso ntchito ngati chigawo cha deodorant ndi detergent.
