Refractive index of milk
Webof water which was added to milk. The refractive index of milk is difficult to estimate due to light scattering by casein micelles and fat globules; however, by using Abbe’s refractometer it is possible to make satisfactory measurements (12). The refractive index of the fresh breast milk samples were found to be 1.3494 to 1.3510, that is lower WebThe reading is generally taken at 40°C. The normal value of the refractive index of milk fat varies between 1.4538 and 1.4578. When compared to other milk fats and oils, the refractive index value of milk fat is low because of the graeter number of saturated glycerides and short chain acids in milk fat. Saponification number
