Food Grade Natural Food Preservative polylysine hmoov
Product Description
Polylysine yog ib qho polymer uas muaj lisine monomers, feem ntau pom muaj nyob rau hauv cov ntaub ntawv ntuj los yog hluavtaws. Nws muaj ntau yam kev siv, suav nrog hauv kev lag luam khoom noj, tshuaj thiab biotechnology.
Polylysine (ε-poly-L-lysine, EPL) yog homopolymer me me ntawm qhov tseem ceeb amino acid L-lysine uas yog tsim los ntawm
kab mob fermentation. ε-Poly-L-lysine yog siv los ua ib qho khoom noj khoom haus zoo hauv cov khoom noj khoom haus.ε-Polylysine belongs rau pawg ntawm cationic polymers. Hauv dej, ε-polylysine muaj cov pab pawg zoo hydrophilic amino. Raws li kev tshawb fawb, ε-polylysine yog adsorbed electrostatically mus rau lub cell nto ntawm cov kab mob, ua raws li los ntawm ib tug stripping ntawm lub txheej membrane.Qhov no nws thiaj li ua rau lub txawv txav ntawm qhov ua rau kev puas tsuaj rau cov kab mob ntawm tes.
ε-Polylysine tau lees paub tias yog cov khoom muaj kev nyab xeeb heev hauv zej zog kev tshawb fawb. ε-Polylysine feem ntau tau lees paub tias muaj kev nyab xeeb li zaub mov preservative thaum Lub Kaum Hli, 2003.Nws tau pom zoo siv los ua cov tshuaj tua kab mob hauv cov nplej siav lossis sushi mov ntawm qib txog li 50 milligrams ib kilogram (mg / kg) ntawm mov. Cov txiaj ntsig ntawm kev tshawb fawb txog kev mob toxicity thiab kev kuaj kab mob rau mutagenicity qhia tau hais tias ε-Polysine tsis muaj tshuaj lom thiab tsis muaj pov thawj rau mutagenic kev ua ntawm ε-Polysine. Yog li ε-Polylysine muaj kev nyab xeeb kiag li siv los ua zaub mov noj.

Muaj nuj nqi
- Khoom noj khoom haus preservative:Polylysine yog dav siv los ua zaub mov preservative, uas muaj peev xwm inhibit qhov kev loj hlob ntawm cov kab mob, pwm thiab poov xab thiab ntev lub txee lub neej ntawm cov zaub mov. Nws tuaj yeem hloov cov tshuaj tiv thaiv ib txwm muaj thiab muaj txiaj ntsig zoo dua rau kev nyab xeeb khoom noj.
- Pharmaceutical teb:Polylysine muaj cov tshuaj tua kab mob thiab tshuaj tua kab mob thiab yog li siv hauv kev lag luam tshuaj, xws li tshuaj tua kab mob lossis tshuaj tua kab mob hauv cov tshuaj formulations. Tsis tas li ntawd, nws yog siv nyob rau hauv kev kho mob hnav khaub ncaws thiab tshuaj sustained-tso systems.
- Biotechnology:Nyob rau hauv lub teb ntawm biotechnology, polylysine yog siv los ua ib qho additive rau cell kab lis kev cai xov xwm los pab cell loj hlob thiab proliferation. Nws tseem tuaj yeem siv los qhwv thiab tiv thaiv nucleic acid molecules xws li DNA thiab RNA rau kev hloov pauv noob thiab kev sim hloov pauv.
Zuag qhia tag nrho, polylysine yog ib qho kev sib xyaw ua ke nrog ntau yam kev siv, suav nrog kev khaws zaub mov, tshuaj tua kab mob thiab tshuaj tua kab mob hauv thaj chaw tshuaj, thiab kab lis kev cai ntawm tes thiab nucleic acid tiv thaiv hauv biotechnology teb.
