Question

cow eat grass but grass is green and the milk is white why ​

Answer 1

Answer:

Some of the nutrients that are found in milk are coloured. Riboflavin or vitamin B2 which is an important enzyme cofactor has a greenish yellow hue. It is water soluble and is most readily visible in the whey that forms when the liquid portion of milk is separated from the solids, as in cheese making. The fat globules in milk can also have a yellow tinge due to carotenoids, such as beta-carotene, which stems from the diet. Beta-carotene has nutritional importance because it is a precursor to vitamin A. Summer milk from cows that dine on green pastures is yellower because grass has more beta-carotene than hay does. This is also why butter in the summer is yellow and is white in the winter.

Answer 2

Answer:

Milk is naturally a white substance due to the make-up of water and other components including fat and protein that mix together to form tiny particles which reflect light. ... When light hits these casein micelles it causes the light to refract and scatter resulting in milk appearing white.
