Ho?ohana ?ia ka lactate no ka mālama ?ana i ka mea?ai, ho?oma?ema?e a ho?onui i ka ?ono

Ho?ohana ?ia ?o Sodium L-lactate no ka mālama ?ana i ka mea?ai, ho?oma?ema?e a me ka ho?onui ?ana i ka ?ono, a me ka casein toughening agent a me ka wai ho?ohehe?e wai. Ma ke ?ano o ka bacteriostasis mea?ai, ?a?ole hiki i ka L-sodium lactate ke pale wale i ka hana hou ?ana o ka hapa nui o ka bacteria spoilage, akā loa?a nā ?ano like ?ole o ka inhibition i nā bacteria pathogenic, e like me Listeria monocytogenes, Salmonella, etc. Ua ho?ohana maika?i ?ia ?o Sodium L-lactate i nā huahana ?i?o holo?oko?a e like me ka ham i kuke ?ia, ka pipi ?ōpala, ka umauma moa, a me nā huahana ?i?o minced e like me ka sausage ?īlio wela, sausage hou, sausage puhi a me nā salami.

Ho?ohana nui ?ia ia i ka hana ?ana a me ka hana ?ana i nā mea polylactic acid a me ka synthesis o nā lā?au chiral a me nā intermediates pesticide.

Lactic acid esters e ho?ohana ana i ka D-lactic acid e like me nā mea maka i ho?ohana nui ?ia i ka hana ?ana i nā mea ?ala, nā synthetic resin coatings, adhesives a me nā inika pa?i, a me ka ho?oma?ema?e ?ana i nā pipeline petroleum a me nā ?oihana uila. I waena o lākou, hiki ke hui like ?ia ka D-methyl lactate me ka wai a me nā mea ho?ohehe?e polar like ?ole, cellulose acetate, cellulose acetobutyrate, etc. He mea ho?ohehe?e maika?i loa me ka helu ho?olapalapa ki?eki?e ma muli o kāna mau mea maika?i o ka wela ki?eki?e a me ka wikiwiki evaporation lohi. Hiki ke ho?ohana ?ia ma ke ?ano he ?āpana o ka solvent hui e ho?omaika?i i ka hana a me ka solubilization. Eia kekahi, hiki ke ho?ohana ?ia ma ke ?ano he mea maka no nā lā?au lapa?au, pesticides a me nā precursors no ka synthesis o nā pūhui chiral ?ē a?e. , Kūwaena.
Mea ho?ohehe?e ?ia
?O ka waikawa lactic ka mea maka no ka bioplastic polylactic acid (PLA). ?O nā waiwai kino o nā mea PLA e pili ana i ka haku mele a me ka ?ike o D a me L isomers. ?O ka racemate D, L-polylactic acid (PDLLA) synthesized mai racemic D, L-lactic acid he ?ano amorphous, a ?ilihune kona mau waiwai mechanical, pōkole ka manawa degradation, a hiki i ka shrinkage i ke kino, me ka shrinkage rate o 50%. % a ?oi aku paha, ua kaupalena ?ia ka noi. Ho?onohonoho mau ?ia nā ?āpana kaulahao o L-polylactic acid (PLLA) a me D-polylactic acid (PDLA), a ?oi aku ka ki?eki?e o ko lākou crystallinity, mechanical strength and melting point ma mua o ka PDLLA.
