Primjena ultrafiltracije mlijeka u izradi sireva postiže sve zapaženije rezultate. Zato je ona predmet mnogih ispitivanja i utvrđivanja prednosti koje sa sobom donosi. U ovom radu je ispitivan različit sadržaj i međusobni odnos pojedinih proteinskih frakcija kod sireva različite vrste, različitog stepena zrelosti, različitog načina skladištenja i pakovanja. Ispitivani su bijeli meki sir, somborski sir, vrsta polutvrdog sira i topljeni i dr., proizvedeni procesima ultrafiltracije. Utvrđeno je da se u relativnim i apsolutnim odnosima poboljšava biološka vrijednost sireva, zbog povećanog sadržaja proteina surutke., Content of certain nitrogen, i.e. protein fractions in different kind cheeses made by ultrafiltration is investigated. Althought the content depends on type of cheeses, applying the MMV method or in combination with classical one, period of ripening of cheese ect. The concentration of noncasein nitrogen m all cheeses produced by ultrafiltration was significantly higher. This may influence on process of cheese ripening and final organoleptic characteristics of final products. A little data is available in the literature about this subject, so, consequently, much more investigations is needed.
