DETERMINATION OF FAT AND PROTEIN CONTENT OF GOAT MILK USING HE-NE LASER LIGHT SCATTERING METHOD

<strong>ABSTRACT </strong>In this study He-Ne laser light scattering method was used to determine the fat and protein content of goat milk sample. The study was carried out the month of March and April with four respective weeks. The goat milk samples were examined in the month of March and April. Based on the laser light scattering theory, the ratio of the scattered light intensity to the transmitted light intensity is taken on as the optical parameter characterizing the fat and protein content. Finally, the data analysis was carried out by using curve and surface fitting method. The result shows that, the amount of fat contents of goat milk sample in the month of March and April is ranged from 4.314% to 4.641% and from 3.605% to 3.941% respectively with four respective weeks. The amount of protein content of goat milk sample in the month of March and April is varied from3.502% to 4.085% and from 2.72%to 3.269% respectively with four respective weeks. The average fat and protein content of goat milk is 4.13% and3.39% respectively.
