Lactate waxaa loo isticmaalaa ilaalinta cuntada, qoyaanka iyo kobcinta dhadhanka
Sharaxaada
Sodium L-lactate waxaa loo isticmaalaa ilaalinta cuntada, qoyaanka iyo kobcinta dhadhanka, iyo sidoo kale wakiilka adkaynaya casein iyo wakiilka biyaha nuugista. Marka la eego bacteriostasis cuntada, L-sodium lactate kaliya ma joojin karto taranka bakteeriyada ugu badan, laakiin sidoo kale waxay leeyihiin heerar kala duwan oo ka hortag ah oo ku saabsan bakteeriyada pathogenic badan, sida Listeria monocytogenes, Salmonella, iwm. Sodium L-lactate ayaa si guul leh loogu isticmaalay hilibka oo dhan sida ham karsan, hilib lo'aad oo duban, naaska digaaga, iyo hilibka duqadda ah sida sausage eyga kulul, sausage cusub, bolse sigaar cabbin iyo salami.

Codsiga
Waxaa inta badan loo isticmaalaa habaynta iyo soo saarista alaabta polylactic acid iyo isku dhafka daawooyinka chiral iyo dhexdhexaadiyeyaasha sunta cayayaanka.
Iskudhisyada Chiral
Aashitada lactic acid esters iyadoo la adeegsanayo D-lactic acid sida alaabta ceeriin ayaa si weyn loogu isticmaalaa soo saarista cadarka, dahaarka resin synthetic, koollada iyo khadadka daabacaadda, iyo sidoo kale nadiifinta dhuumaha batroolka iyo warshadaha elektiroonigga ah. Waxaa ka mid ah, D-methyl lactate si siman loogu qasi karaa biyaha iyo dareerayaasha kala duwan ee polar, acetate cellulose, acetobutyrate cellulose, iwm iyo polymers synthetic polar kala duwan, oo uu leeyahay barta dhalaalaysa. Waa dareere aad u fiican oo leh barta karkarinta sare sababtoo ah faa'iidooyinka heerkulka sare iyo heerka uumiga oo gaabis ah. Waxaa loo isticmaali karaa qayb ka mid ah dareeraha isku dhafan si loo hagaajiyo karti-shaqsiyeedka iyo milanka. Intaa waxaa dheer, waxaa sidoo kale loo isticmaali karaa sida alaabta ceeriin ee daawooyinka, sunta cayayaanka iyo horudhacyada loogu talagalay isku dhafka xeryahooda kale ee chiral. , Dhexdhexaad.
Wax la dumin karo
Lactic acid waa alaabta ceeriin ee bioplastic polylactic acid (PLA). Astaamaha jireed ee agabka PLA waxay ku xidhan yihiin halabuurka iyo waxa ay ka kooban yihiin D iyo L isomers. Race-mate D, L-polylactic acid (PDLLA) oo laga soo saaray jinsiyadda D, L-lactic acid waxay leedahay qaab dhismeed amorphous ah, iyo sifooyinkeeda makaanikada waa liitaa, wakhtiga hoos u dhaca waa gaaban yahay, iyo hoos u dhaca ayaa ku dhaca jidhka, oo leh heerka hoos u dhaca 50%. % ama ka badan, codsigu wuu xadidan yahay. Qaybaha silsiladda L-polylactic acid (PLLA) iyo D-polylactic acid (PDLA) si joogto ah ayaa loo habeeyaa, iyo crystallinity-kooda, xoogga farsamada iyo barta dhalaalka ayaa aad uga sarreeya kuwa PDLLA.
