| dc.description.abstract | This study was initiated with the objectives to enhance the accuracy of determining the intended components inside the selected milk samples like the amount of fat and protein contents and to develop optical method for the determination of the amount of fat and protein content in the milk samples. I implemented the ratio of the scattered to transmitted light intensity as the principal analysis parameter to minimize the power fluctuation of the light source during doing the experiment. The amount of fat contents and protein contents of five (Family, Etete, Harme, Sholla and Mama) homogenized milk samples were determined. In this work we used laser light scattering method. Finally, the data analysis was carried out using curve and surface fitting method. My result shows that, the amount of fat contents in each (Family, Etete, Harme, Shola and Mama) homogenized milk samples are 2.700%, 2.500%, 2.800%, 2.900% and 2.800% respectively. But the amount of fat content written in the packets to each (Family, Etete, Harme, Shola, Mama) milk samples are 2.700%, 2.800%, 2.800%, 2.700% and 2.700% respectively which are almost consistent to experimental results. The amount of protein contents that is found in each (Family, Etete, Harme, Shola and Mama) homogenized milk samples become 3.600 0 0 , 3.900 0 0 , 3.800 0 0 , 3.500 0 0 and 3.500 0 0 respectively. The amount of protein contents written in the packets to each (Family, Etete, Harme, Shola, Mama) milk samples are also 3.500%, 3.500%, 3.500%, 3.500% and 3.500% respectively which are also almost consistent to experimental results. It may be concluded that, the laser light scattering method provides a simple and direct method to determine fat and protein contents in investigated milk samples | en_US |
