Lactate e sebelisetsoa ho boloka lijo, ho nosetsa le ho matlafatsa tatso
Tlhaloso
Sodium L-lactate e sebelisoa bakeng sa ho boloka lijo, ho nosetsa le ho ntlafatsa tatso, hammoho le ntho e toughening ea casein le e monyang metsi. Mabapi le bacteriostasis ea lijo, L-sodium lactate e ke ke ea thibela feela ho ikatisa ha libaktheria tse ngata tse senyang, empa hape e na le likhato tse fapaneng tsa ho thibela likokoana-hloko tse ngata tsa pathogenic, tse kang Listeria monocytogenes, Salmonella, joalo-joalo Sodium L-lactate e sebelitse ka katleho lihlahisoa tsa nama e felletseng joalo ka nama e phehiloeng, nama ea khomo e halikiloeng, sefuba sa khoho le lihlahisoa tsa nama e halikiloeng joalo ka boroso ea lintja tse chesang, boroso e ncha, boroso e tsubang le salami.

E sebelisoa haholo ha ho etsoa le ho etsa thepa ea asiti ea polylactic le motsoako oa lithethefatsi tsa chiral le li-intermediates tsa chefo e bolaeang likokoanyana.
Metsoako ea Chiral
Li-ester tsa lactic acid tse sebelisang D-lactic acid e le lisebelisoa tse tala li sebelisoa haholo tlhahisong ea litlolo tse nkhang hamonate, litlolo tsa maiketsetso tsa resin, likhomaretsi le liinke tsa khatiso, hape le tlhoekisong ea lipeipi tsa peterole le liindasteri tsa elektroniki. Har'a tsona, D-methyl lactate e ka kopanngoa ka mokhoa o ts'oanang le metsi le li-solvents tse sa t?oaneng tsa polar, cellulose acetate, cellulose acetobutyrate, joalo-joalo le li-polar synthetic polymers tse sa t?oaneng, 'me li na le ntlha ea ho qhibiliha.

E ka sebelisoa e le karolo ea motsoako oa motsoako ho ntlafatsa ts'ebetso le ho kopanya. Ntle le moo, e ka sebelisoa e le thepa e tala bakeng sa meriana, chefo e bolaeang likokoanyana le li-precursors bakeng sa ho kopanya metsoako e meng ea chiral. , Ea Mahareng.
Lintho tse senyehang
Lactic acid ke thepa e tala bakeng sa bioplastic polylactic acid (PLA). Thepa ea 'mele ea thepa ea PLA e it?etlehile ka sebopeho le litaba tsa D le L li-isomers. Racemate D, L-polylactic acid (PDLLA) e entsoeng ho tloha racemic D, L-lactic acid e na le sebopeho sa amorphous, 'me thepa ea eona ea mechine e futsanehile, nako ea ho senyeha e khut?oanyane,' me ho fokotseha ho etsahala 'meleng, ka tekanyo ea ho fokotseha ea 50%. % kapa ho feta, ts'ebeliso e na le moeli. Likarolo tsa ketane tsa L-polylactic acid (PLLA) le D-polylactic acid (PDLA) li lula li hlophisoa, 'me crystallinity ea bona, matla a mochine le ntlha ea ho qhibiliha li phahame haholo ho feta tsa PDLLA.
