Abstract 

The present study was aimed at analyzing the physico-chemical quality of milk, collected from the urban areas of Oromia special zone surrounding Finfinne, central highland of Ethiopia namely Burayu, Sabeta and sululta. A total of 30 milk samples (10 from farm/producer, 10 from milk collectors, and 10 from the cafeteria) were collected from each urban area and the samples were analyzed for the physic-chemical parameters namely  Added water, pH, specific gravity freezing point ,titrable acidity, protein ,lactose, fat, total soiled ,ash, and solid nonfat  to assess the quality of milk. For the analyses of data General Linear Model (GLM) was implemented. The result of (mean±SE) percentage of added water, pH, and Specific gravity were a significant difference (p<0.05) between the study town but there was no significant difference between the study town in the finding of titratable acidity and freezing point. All the physical parameters namely Added water, pH, specific gravity titrable acidity of milk quality obtained from farms, milk collectors, and cafeterias were significantly different (p<0.05) except freezing point. The mean result of protein, lactose, fat, and TS were significantly different (p<0.05) between Burayu, Sabeta, and Sululta but no statistical difference between study town in the result of SNF and ash percentage. Except for ash, all the chemical compositions of milk were significantly different (p<0.05) among the producer, collectors and cafeteria. From this result, most of the physicochemical property of milk sample obtained from farm fulfill the minimum requirement of Ethiopia quality standard but when comas to the milk collectors and cafeterias, the physicochemical quality  was below the limits of Ethiopia quality standard, this indicated that the adulteration of milk in the study area increased from producer to end-user. The finding of this study provided recent information on milk physicochemical quality from farm to the cafeteria which can be an important input for regulatory bodies (EFDA) of Ethiopia.
