WHY DOES MILK LOOK WHITE IN COLOUR? |
Good Question. Milk is white because of its reflectance properties. The reason anything is white is that it reflects all wavelengths of light and absorbs none, therefore it is white.All milk is white but the shades of white will vary depending upon the composition or what is dissolved in the milk. The most important factors that contribute to the color of milk are fat, how much cassein there is (milk proteins) and calcium complexes ( minerals), and how much water-soluble riboflavin. These compounds contribute to milk's opaque or ivory color by interfering with light transmission. Because there are so many fat and protein molecules in milk that enough light at all wavelengths gets scattered giving the appearance of white light |
