THE COMPOSITIONAL AND HYGIENIC-SANITARY ANALYSIS OF JENNET MILK

Nowadays, the interest in jennet milk has considerably increased worldwide due to its nutritional characteristics. This study aimed to analyse the main physicochemical and hygienic-sanitary parameters of some jennet milk samples, by using current methods of quality monitoring. The following physicochemical (dry matter DM, non-fat dry matter NDM, fat, total protein, fl-casein, lactose, and cryoscopic point), metabolic (urea, acetone, and fl-hydroxybutyrate BHB) and hygienic parameters (total bacteria count TBC, somatic cell count SCC and differential somatic cell count DSCC) were assessed. Additionally, electrical conductivity (EC), pH, temperature, and density were investigated. The results revealed variations of total DM (9.64-11.11%), which were mainly given by the NDM oscillations (8.62-9.54%) and to a lesser extent by the fat content (0.25-1.66%). The study also emphasized low values of EC (1.75 mS/cm), TBC (22.16-62.15x103 CFU/mL), and SCC (3-30x103 cells/mL). The good health status was also confirmed by other metabolic indices, such as urea (36.27 mmol/L), acetone (0.06 mmol/L), and BHB (0.14 mmol/L).
