Lactate e fa?aaogaina mo le fa?asaoina o mea?ai, susu ma fa?aleleia atili le tofo
Fa'amatalaga
O le Sodium L-lactate e fa?aaogaina mo le fa?asaoina o mea?ai, fa?asusu ma fa?aleleia le tofo, fa?apea fo?i ma le casein toughening agent ma le vai miti. I tulaga o mea?ai bacteriostasis, L-sodium lactate e le gata e mafai ona fa?alavelaveina le toe gaosia o le tele o siama fa?aleagaina, ae o lo?o i ai foi tulaga eseese o le fa?asaina i luga o le tele o siama pathogenic, e pei o Listeria monocytogenes, Salmonella, ma isi. O le Sodium L-lactate ua fa?aaogaina lelei i mea?ai atoa e pei o ham vela, povi tao, susu moa, ma mea?ai aano o manufasi e pei o sosisi hot dog, sosisi fou, sosisi ulaula ma salami.

Fa'aaogāga
E masani ona fa?aaogaina i le gaosiga ma le gaosiga o mea polylactic acid ma le tu?ufa?atasia o vaila?au fa?ama?i ma vaila?au fa?ama?i.
Kiral compounds
Lactic acid esters e fa?aaoga ai le D-lactic acid e pei o mea mata?utia o lo?o fa?aaogaina lautele i le gaosiga o mea manogi, fa?apipi?i resini fa?apipi?i, fa?apipi?i ma lomitusi vaitusi, fa?apea fo?i i le fa?amamaina o paipa suauu ma pisinisi eletise. Faatasi ai ma i latou, o le D-methyl lactate e mafai ona fa?afefiloi tutusa ma le vai ma le tele o solvents polar, cellulose acetate, cellulose acetobutyrate, ma isi mea ma isi polymers synthetic polar, ma e iai se mea fa?afefe. O se solvent sili ona lelei ma le maualuga o le vevela ona o lona lelei o le maualuga o le vevela ma le fa?agesegese o le fa?afefe. E mafai ona fa?aaogaina e avea o se vaega o solu fefiloi e fa?aleleia ai le galue ma le solubilization. E le gata i lea, e mafai foi ona fa?aaogaina e avea o se mea mata?utia mo vaila?au, vailaau fa?ama?i ma precursors mo le fa?apipi?iina o isi mea fa?apipi?i chiral. , Intermediate.
Mea fa'aleagaina
O le lactic acid o le mea masani lea mo le bioplastic polylactic acid (PLA). O mea fa?aletino o mea PLA e fa?alagolago i le tu?ufa?atasia ma mea o lo?o i totonu o D ma L isomers. O le racemate D, L-polylactic acid (PDLLA) fa?apipi?iina mai le racemic D, L-lactic acid o lo?o i ai se fausaga amorphous, ma o ana mea fa?ainisinia e le lelei, o le taimi fa?aleagaina e puupuu, ma fa?aitiitia ai le tino, fa?atasi ai ma le fa?aitiitia o le 50%. % pe sili atu, o le talosaga e fa?atapula?aina. O vaega filifili o le L-polylactic acid (PLLA) ma le D-polylactic acid (PDLA) e masani ona fa?atulagaina, ma o latou tioata, malosi fa?ainisinia ma le fa?afefeteina e sili atu le maualuga nai lo le PDLLA.
