Physicochemical characterization and correlation of raw cow’s milk according to classification assigned in Panama

Introduction. Currently, there are no bibliographic or statistical records that allow establishing a correlation between the physical-chemical quality characteristics of raw cow’s milk produced in Republic Panama and classification it receives. Objective. To characterize quantify parameters correlate these with receives Panama. Materials methods. A stratified sampling was carried out according to cow´s (grade A, B, C), 48 grade 71 393 C. Random samples were taken Cocle, Veraguas, Herrera Los Santos during rainy season from June September 2018. In Chiriquí province, conducted dry season, January March 2019. addition, necessary have at least 512 producers farms, so analysis reached confidence level 95 %, standard deviation 5 limit error %. Results. The values found us consider has international standards. indicated protein had high relationship solids non-fat (SNF), density (D), lactose (L) (0.93, 0.91, 0.96, respectively); also L is strongly related SNF D (0.94 0, 91, respectively). Conclusions. variance did not establish significant differences three existing classifications country, which distribution grades parameters. However, possible some
