Lactate inoshandiswa kuchengetedza chikafu, kunyorova uye kuwedzera kunaka
Tsanangudzo
Sodium L-lactate inoshandiswa kuchengetedza chikafu, kunyorova uye kuwedzera flavour, pamwe necasin toughening agent uye mvura inonwisa mvura. Panyaya yekudya bacteriostasis, L-sodium lactate haigoni kungodzivisa kubereka kwebhakitiriya yakawanda inoparadza, asi inewo maitiro akasiyana-siyana ekudzivisa mabhakitiriya akawanda epathogenic, akadai seListeria monocytogenes, Salmonella, nezvimwewo. Sodium L-lactate yakashandiswa zvinobudirira muzvigadzirwa zvenyama senge nyama yakabikwa, nyama yemombe yakagochwa, zamu rehuku, uye zvigadzirwa zvenyama yakagochwa senge sausage yembwa inopisa, soseji nyowani, soseji inoputa uye salami.

Application
Inonyanya kushandiswa mukugadzirisa nekugadzira zvinhu zvepolylactic acid uye kugadzirwa kwemishonga yechiral uye mishonga yezvipembenene.
Chiral compounds
Lactic acid esters inoshandisa D-lactic acid semidziyo inoshandiswa zvakanyanya mukugadzirwa kwezvinonhuhwirira, synthetic resin coatings, zvinonamira neingi dzekudhinda, uye zvakare mukuchenesa mapaipi epetroleum uye maindasitiri emagetsi. Pakati pavo, D-methyl lactate inogona kusanganiswa nemvura uye zvakasiyana-siyana zvinonyungudutsa polar, cellulose acetate, cellulose acetobutyrate, nezvimwewo uye zvakasiyana-siyana polar synthetic polymers, uye ine nzvimbo yekunyunguduka. Iyo yakanakisa solvent ine yakakwira yekubikira poindi nekuda kwemabhenefiti ayo ekushisa kwakanyanya uye inononoka evaporation rate. Inogona kushandiswa sechikamu chemusanganiswa solvent kuvandudza kushanda uye solubilization. Pamusoro pezvo, inogona zvakare kushandiswa seyakabikwa yemishonga, mishonga yezvipembenene uye precursors ye synthesis yemamwe chiral makomisheni. , Pakati.
Zvinhu zvinoshatisa
Lactic acid ndiyo mbishi yezvinhu zvebioplastic polylactic acid (PLA). Hunhu hwemuviri hwezvinhu zvePLA zvinoenderana nekuumbwa uye zvirimo zveD uye L isomers. Iyo racemate D, L-polylactic acid (PDLLA) yakagadzirwa kubva ku racemic D, L-lactic acid ine amorphous chimiro, uye maitiro ayo emagetsi akashata, nguva yekuora ipfupi, uye shrinkage inoitika mumuviri, ine shrinkage rate ye50%. % kana kupfuura, iyo application ishoma. Zvikamu zveketani zveL-polylactic acid (PLLA) uye D-polylactic acid (PDLA) zvinogara zvakarongwa, uye crystallinity yavo, simba remagetsi uye nzvimbo yekunyunguduka zvakakwirira kudarika izvo zvePDLLA.
