The isolation and use of dairy proteins

Mlijeko je veoma bogato proteinima i ima veliku biološku vrijednost. Još od davnih vremena mlijeko raznih životinja koristi se za prehranu ljudi. Kazein, koji obuhvaća oko 80 % ukupnih proteina mlijeka, glavna je sirovina za proizvodnju sira. Uz to, može se upotrebljavati i za proizvodnju ljepila, plastike itd. Ostalih 20 % proteina mlijeka su proteini sirutke, koji se zbog svoje prehrambene i nutritivne vrijednosti mogu koristiti kao sirovina za proizvodnju raznih prehrambenih proizvoda (proteinski dodaci, fermentirani napitci, albuminski sir).Milk contains plenty of proteins and it has a high biological value. Since ancient times, milk from various animals has been used for human nutrition. Casein, which takes up to 80% of all milk proteins, is the main raw material for the production of cheese. It can also be used for the production of glue, plastic etc. The remaining 20% of milk proteins are whey proteins, which can be used as raw material for the production of various alimentary products (protein supplements, fermented beverages, albumin cheese) because of their alimentary and nutritional value
