摘要

This study aimed to compare the physicochemical and microbiological properties of milk from different ruminant species. Between October 2021 and July 2022, a total of 120 milk samples were collected from cattle, sheep, goats, and camels (30 samples per species) and analyzed for pH, fat content, acidity, density, and mineral composition. Microbiological testing was also performed to assess potential contamination. The results revealed significant differences among species (p < 0.05). Goat milk had the lowest pH (6.4) and the highest total dry extract (151.87 g/L), whereas camel milk exhibited the lowest dry extract (112.37 g/L) and fat content (29.7 g/L). Sheep milk showed the highest acidity (19.86°D) and fat content (54.75 g/L), whereas camel milk had the lowest density (1025.2). All milk samples were microbiologically safe, with no detection of bacterial, yeast, or mold contamination. Fatty acid analysis using gas chromatography-mass spectrometry (GC/MS) indicated that sheep milk contained the highest butyric acid (3.31%), goat milk had the highest level of capric acid (12.03%), and camel milk was rich in unsaturated fatty acids, including oleic, α-linolenic, and γ-linolenic acids. Mineral analysis showed that goat and sheep milk were highest in calcium and magnesium, while camel milk had the greatest concentrations of potassium and iron. Principal Component Analysis (PCA) confirmed distinct fatty acid profiles for each species. These findings offer valuable insights for improving milk quality, guiding the formulation of dairy products, enhancing animal feeding strategies, and ensuring food safety.
