ε- Polylysine yog lub teeb daj hmoov nrog muaj zog hygroscopicity thiab ib qho iab saj. Nws yog ib tug ncaj saw polymer ntawm lysine. Nws tsis cuam tshuam los ntawm tus nqi pH, yog thermally ruaj khov (120 degree , 20 feeb), thiab tuaj yeem tiv thaiv cov kab mob kub-resistant, yog li nws tuaj yeem kho cua sov tom qab ntxiv. Txawm li cas los xij, thaum ntsib acidic polysaccharides, hydrochloride ntsev, phosphates, tooj liab ions, thiab lwm yam, lawv cov dej num yuav raug txo vim kev khi. Thaum ua ke nrog hydrochloric acid, citric acid, malic acid, glycine, thiab ntau dua fatty glycerides, nws muaj synergistic teebmeem. Molecular hnyav ntawm 3600-4300 ε- Polylysine muaj cov tshuaj tua kab mob zoo tshaj plaws, thiab thaum nws qhov hnyav molecular qis dua 1300, ε- Polylysine poob nws cov tshuaj tua kab mob. Vim lub fact tias polylysine yog ib tug sib tov, nws tsis muaj ib tug taag melting point thiab pib soften thiab decompose saum 250 degree. ε Polylysine yog soluble hauv dej thiab me ntsis soluble hauv ethanol. Infrared spectrum tsom xam ntawm nws tus yam ntxwv qhia tau hais tias muaj zog nqus peaks ntawm 1680-1640cm-1 thiab 1580-1520cm-1.
