The chemical composition of milk can vary considerably depending on several factors including species, breed, individuals, stage of lactation, age, health status and feeding regimen [1]. Raw bovine milk usually contains 3–5% of fat, 3.5–4% protein, 4.5–5% lactose and ~12% of dry matter, while commercial milk samples were characterised by a lower level of fat due to industrial recovery of this component. Twenty one local milk samples containing 1.5–3.2% of fat and typical amounts of protein and carbohydrates were selected for analysis.
