Lactate imagwiritsidwa ntchito posungira chakudya, kunyowetsa komanso kuwonjezera kukoma
Kufotokozera
Sodium L-lactate imagwiritsidwa ntchito posungira chakudya, kunyowetsa ndi kukulitsa kukoma, komanso casein toughening agent ndi wothandizira madzi. Pankhani ya bacteriostasis chakudya, L-sodium lactate osati ziletsa kubereka kwa mabakiteriya ambiri spoilage, komanso mosiyanasiyana zopinga ambiri tizilombo mabakiteriya, monga Listeria monocytogenes, Salmonella, etc. , Potero mogwira kukulitsa alumali moyo wa nyama. Sodium L-lactate yakhala ikugwiritsidwa ntchito bwino muzakudya zonse za nyama monga nyama yophika, nyama yowotcha, bere la nkhuku, ndi nyama ya minced monga soseji ya agalu otentha, soseji yatsopano, soseji wosuta ndi salami.

Kugwiritsa ntchito
Amagwiritsidwa ntchito pokonza ndi kupanga zida za polylactic acid ndi kaphatikizidwe ka mankhwala a chiral ndi mankhwala ophera tizilombo.
Mankhwala a Chiral
Ma ester a lactic acid omwe amagwiritsa ntchito D-lactic acid monga zida zopangira amagwiritsidwa ntchito kwambiri popanga mafuta onunkhira, zokutira zopangira utomoni, zomatira ndi inki zosindikizira, komanso pakuyeretsa mapaipi amafuta ndi mafakitale amagetsi. Pakati pawo, D-methyl lactate ikhoza kusakanikirana mofanana ndi madzi ndi zosungunulira zosiyanasiyana za polar, cellulose acetate, cellulose acetobutyrate, etc. ndi ma polima osiyanasiyana a polar synthetic, ndipo ali ndi malo osungunuka. Ndiwosungunulira wabwino kwambiri wokhala ndi malo otentha kwambiri chifukwa cha zabwino zake za kutentha kwambiri komanso kutsika pang'onopang'ono kwa evaporation. Itha kugwiritsidwa ntchito ngati gawo la zosungunulira zosakanikirana kuti zithandizire kukhazikika komanso kukhazikika. Kuphatikiza apo, itha kugwiritsidwanso ntchito ngati zida zopangira mankhwala, mankhwala ophera tizilombo komanso zoyambira pakuphatikiza mankhwala ena a chiral. , Wapakatikati.
Zinthu zowonongeka
Lactic acid ndiye zopangira za bioplastic polylactic acid (PLA). Zomwe zimapangidwa ndi zinthu za PLA zimadalira kapangidwe kake ndi zomwe zili mu D ndi L isomers. Racemate D, L-polylactic acid (PDLLA) yopangidwa kuchokera ku racemic D, L-lactic acid ili ndi mawonekedwe aamorphous, ndipo makina ake ndi osauka, nthawi yowonongeka ndi yochepa, ndipo kuchepa kumapezeka m'thupi, ndi kuchepa kwa 50%. % kapena kupitilira apo, kugwiritsa ntchito kumakhala kochepa. Zigawo za L-polylactic acid (PLLA) ndi D-polylactic acid (PDLA) zimakonzedwa nthawi zonse, ndipo crystallinity yawo, mphamvu zamakina ndi malo osungunuka ndizokwera kwambiri kuposa za PDLLA.
