I-lactate isetshenziselwa ukulondoloza ukudla, ukuthambisa kanye nokuthuthukisa ukunambitheka
Incazelo
I-Sodium L-lactate isetshenziselwa ukulondoloza ukudla, ukuthambisa kanye nokuthuthukisa ukunambitheka, kanye ne-casein ejenti eqinisayo kanye ne-ejenti emunca amanzi. Ngokuphathelene ne-bacteriostasis yokudla, i-L-sodium lactate ayikwazi ukuvimbela kuphela ukukhiqizwa kwamagciwane amaningi abhubhisayo, kodwa futhi ibe namazinga ahlukene okuvimbela amagciwane amaningi e-pathogenic, njenge-Listeria monocytogenes, i-Salmonella, njll. I-Sodium L-lactate isetshenziswe ngempumelelo emikhiqizweni yenyama ephelele efana nenyama ephekiwe, inyama yenkomo egazingiwe, isifuba senkukhu, kanye nemikhiqizo yenyama egayiwe njengamasoseji enja eshisayo, isoseji elisha, isoseji elibhenyiwe kanye ne-salami.

Isicelo
Isetshenziswa kakhulu ekucubunguleni nasekukhiqizeni izinto ze-polylactic acid kanye nokuhlanganiswa kwezidakamizwa ze-chiral kanye nezibulala-zinambuzane.
Ama-Chiral compounds
Ama-ester e-lactic acid asebenzisa i-D-lactic acid njengezinto zokusetshenziswa asetshenziswa kakhulu ekukhiqizeni amakha, okokwenziwa kwe-resin coating, izinto zokunamathisela noyinki wokunyathelisa, kanye nasekuhlanzeni amapayipi kaphethiloli nezimboni zikagesi. Phakathi kwazo, i-D-methyl lactate ingaxutshwa ngokulinganayo namanzi kanye nezinyibilikisi ezihlukahlukene ze-polar, i-cellulose acetate, i-cellulose acetobutyrate, njll kanye nama-polar synthetic polymers ahlukahlukene, futhi inephuzu lokuncibilika. Kuyi-solvent enhle kakhulu enephuzu lokubilisa eliphezulu ngenxa yezinzuzo zayo zokushisa okuphezulu kanye nezinga lokuhwamuka kancane. Ingasetshenziswa njengengxenye ye-solvent exubile ukuze kuthuthukiswe ukusebenza kahle kanye ne-solubilization. Ngaphezu kwalokho, ingasetshenziswa futhi njengempahla eluhlaza yemithi, izibulala-zinambuzane kanye nezandulela zokuhlanganiswa kwamanye ama-chiral compounds. , Ophakathi.
Izinto eziwohlokayo
I-Lactic acid iyimpahla eluhlaza ye-bioplastic polylactic acid (PLA). Izici ezibonakalayo zezinto ze-PLA zincike ekwakhiweni nasekuqukethweni kwama-isomer ka-D no-L. I-racemate D, L-polylactic acid (PDLLA) eyenziwe ku-racemic D, i-L-lactic acid inesakhiwo se-amorphous, futhi izakhiwo zayo zemishini zimbi, isikhathi sokuwohloka sifushane, futhi ukushwabana kwenzeka emzimbeni, ngesilinganiso sokushwabana esingu-50%. % noma ngaphezulu, uhlelo lokusebenza lunomkhawulo. Izingxenye zamaketanga e-L-polylactic acid (PLLA) kanye ne-D-polylactic acid (PDLA) zihlelwa njalo, futhi ubucwebe bazo, amandla emishini nendawo yokuncibilika kuphakeme kakhulu kune-PDLLA.
