Abstract

Pasteurization and sterilization processes were applied on camel milk and their effect on its quality were evaluated in this study Camel milk was subjected to the pasteurization and sterilization process using the USPTO UHT S1 pilot plant and was examined for its compositional components before and after conducting of heat treatment The results indicated non-significant P 0 05 variations between the fresh and both the pasteurized and sterilized camel milk in the mean values of total solids TS solids not fat SNF fat free fatty acids FAA lactose protein casein urea citric acid pH density and acidity after immediate application of heat treatment and also during the storage period However significant P 0 05 differences were found in the pH and the freezing point depression FPD of the pasteurized milk and the FFA and the acidity of the sterilized milk compared to the raw milk Moreover the physicochemical properties of camel milk products showed stability during two weeks of storage at four degree centigrade for the pasteurized milk and room temperature 37 C for the sterilized milk The total bacterial count and coliform were significantly P 0 05 reduced in the pasteurized and sterilized camel milk Furthermore non-significant P 0 05 differences were recorded for sensory properties between the two products whereas the panelists accepted the pasteurized and sterilized products from camel milk This work concluded that both pasteurized and sterilized camel milk products are safe compositionally rich in components and with acceptable and relatively long shelf life Moreover camel milk processing will be one of the profitable industrial products in the future
