Lactate ikoreshwa mukubungabunga ibiryo, kubika neza no kongera uburyohe
Ibisobanuro
Sodium L-lactate ikoreshwa mukubungabunga ibiryo, kubika neza no kongera uburyohe, hamwe na dosiye ikomera ya casein hamwe nogukoresha amazi. Ku bijyanye na bacteriostasis y'ibiryo, L-sodium lactate ntishobora kubuza gusa iyororoka rya bagiteri nyinshi zonona, ariko kandi ifite uburyo butandukanye bwo kubuza bagiteri nyinshi zitera indwara, nka Listeria monocytogène, Salmonella, nibindi, bityo bikongerera neza ubuzima bwibicuruzwa byinyama. Sodium L-lactate yakoreshejwe neza mubicuruzwa byose byinyama nka ham yatetse, inyama zokeje, amabere yinkoko, hamwe nibikomoka ku nyama zokeje nka sausage yimbwa ishyushye, isosi nshya, isosi yanyweye na salami.

Gusaba
Ikoreshwa cyane cyane mugutunganya no gukora ibikoresho bya aside polylactique hamwe no guhuza imiti ya chiral hamwe nabahuza imiti yica udukoko.
Imvange ya Chiral
Acide ya Lactique ikoresha aside D-lactique nkibikoresho fatizo bikoreshwa cyane mugukora parufe, ibishishwa bya resinike, ibifata hamwe na wino yo gucapa, ndetse no mugusukura imiyoboro ya peteroli ninganda za elegitoroniki. Muri byo, lactate ya D-methyl irashobora kuvangwa neza hamwe namazi hamwe nudukoko twinshi twa polar, acetate ya selile, selile acetobutyrate, nibindi hamwe na polimeri zitandukanye za polarike, kandi bifite aho bishonga. Numuti mwiza cyane utetse cyane kubera ibyiza byubushyuhe bwo hejuru hamwe nigipimo cyuka buhoro. Irashobora gukoreshwa nkibigize imvange ivanze kugirango itezimbere imikorere na solubilisation. Byongeye kandi, irashobora kandi gukoreshwa nkibikoresho fatizo byimiti, imiti yica udukoko hamwe nimbanzirizamushinga yo guhuza ibindi bintu bya chiral. Hagati.
Ibikoresho bitesha agaciro
Acide Lactique ni ibikoresho fatizo bya aside bioplastique polylactique (PLA). Imiterere yumubiri wibikoresho bya PLA biterwa nibigize nibirimo D na L. Irushanwa rya D, L-polylactique (PDLLA) ikomatanyirijwe mu bwoko bwa D, aside L-lactique ifite imiterere ya amorphous, kandi imiterere yubukanishi irakennye, igihe cyo kwangirika ni gito, kandi kugabanuka kugaragara mu mubiri, hamwe no kugabanuka kwa 50%. % cyangwa byinshi, gusaba ni bike. Ibice by'urunigi bya L-polylactique (PLLA) na D-polylactique aside (PDLA) bitunganijwe buri gihe, kandi kristu, imbaraga za mashini hamwe no gushonga biri hejuru cyane ugereranije na PDLLA.
