Iimpawu zomzimba kunye neekhemikhali ze-L-malic acid
I-asidi ye-Malic, ekwabizwa ngokuba yi-2-hydroxysuccinic acid, ine-stereoisomers ezimbini ngenxa ye-asymmetric carbon atom kwi-molecule.Ngokwendalo, ikhona ngeendlela ezintathu, ezizezi, i-D-malic acid, i-L-malic acid kunye nomxube wayo we-DL-malic acid.Ikristale emhlophe okanye i-crystalline powder, i-hygroscopicity enamandla, i-soluble ngokulula emanzini kunye ne-ethanol.Inencasa emuncu ngokukodwa.I-asidi ye-Malic isetyenziswa kakhulu kumashishini okutya kunye namayeza.
Ukusetyenziswa kwemveliso ye-L-malic acid
【Ukusetyenziswa】 Isetyenziswa ekwenzeni ii-esters;isetyenziswe kwii-agent ezixubileyo kunye ne-flavoring agents.Ngokwamalungiselelo elizwe lam i-GB 2760-90, inokusetyenziswa kuzo zonke iintlobo zokutya.Njenge-agent emuncu, ingasetyenziselwa endaweni ye-citric acid (malunga ne-80%), ngakumbi kwi-jelly kunye nokutya okusekelwe kwiziqhamo.Le mveliso inomsebenzi wokugcina umbala weziqhamo zendalo, kwaye ingasetyenziswa njengoncedo lokutsalwa kwepectin, iarhente yokukhuthaza ukukhula kwegwele, ukwenza isosi yesoya engenatyuwa kunye neviniga, ukuphucula incasa yepickles, kunye netyuwa. i-emulsion stabilizer ye-margarine, i-mayonnaise, njl.Isetyenziswa kakhulu kwiipreservatives ezahlukeneyo, i-seasonings kunye nezinye izongezo ezidibeneyo.
(1) Ishishini lokutya: Isetyenziselwa ukulungisa nokulungisa iziselo, umbethe, incindi yeziqhamo, kwaye inokusetyenziswa ekwenzeni iilekese, ijem, njl.Isenokusetyenziswa ukulungisa ipH yeyogathi fermentation kwaye isuse i tartrate ekwenzeni iwayini.
(2) Ishishini lecuba: Izinto eziphuma kwi-Malic acid (ezifana nee-esters) zinokuphucula incasa yecuba.
(3) Ishishini lamachiza: Zonke iintlobo zeepilisi kunye neesyrups ezine-malic acid zinokuba nencasa yeziqhamo, enceda ukufunxa kunye nokusasazeka emzimbeni.
(4) Ishishini lemichiza lemihla ngemihla: Liyi-agent edibanisa kakuhle kunye ne-ester agent.Isetyenziswe kwi-toothpaste formulation, i-tablet yokucoca izinyo, i-synthetic fragrance formulation, njl njl. Inokusetyenziswa njengenxalenye ye-deodorant kunye ne-detergent.
