why milk is in white colour?

Answer 1

because thats the way it come out of mammals! Thats the way it is produced, I breast feed for 13 months, so I know!!

Answer 2

Contrary to popular belief, the colour of milk is not purely white. A close examination of the opaque fluid shows tinges of yellow or green.

Milk is secreted from specialised sweat glands, better known as mammary glands (breast or udder) of the female of warm-blooded animals. Blood is pumped to the mammary glands from the heart. The gland separates different substances from the blood and combines them to make milk.

Milk contains several hundred chemical parts. And the dominant colour (white) and the various tinges ? for example, yellow or green ? are attribuatble to these. It has large amounts of vitamin B2 (riboflavin) and some vitamin A. Milk fat, milk sugar (lactose), and the major milk protein, casein, are found only in milk and nowhere else in nature.

The fat in milk is shaped like very small droplets. They can be seen easily under a microscope. When milk stands for a while, the fat rises to the surface and forms a layer of cream. The golden colour and rich look of the cream come from carotene. Fresh green fodder provides the carotene pigment in milk fat. This gives yellow to the milk, especially the creamy layer.

However, the dominant white colour of milk is due to the presence of a special sugar called lactose. When artificially manufactured, lactose looks pure white, devoid of characteristic tinges of milk.

Answer 3

This is caused by the protein called Casein. Rich in calcium, Casein helps contribute to milk's white color.

In addition, the cream that is found in milk contains white colored fat. The more cream in milk the more white it is.

Another reason milk looks white to our naked eyes is because some objects do not absorb very much light. Rather than absorb light, these objects reflect light. For instance, red colored objects reflect only red light and absorb the other colors of light in the rainbow spectrum. The molecules that make up Casein and cream reflect light. That's why milk is white.

Answer 4

fat globules and the smaller casein micelles, which are just large enough to deflect light, contribute to the opaque white color of milk. The fat globules contain some yellow-orange carotene, enough in some breeds — Guernsey and Jersey cows, for instance — to impart a golden or "creamy" hue to a glass of milk. The riboflavin in the whey portion of milk has a greenish color, which can sometimes be discerned in skim milk or whey products. Fat-free skim milk has only the casein micelles to scatter light, and they tend to scatter shorter-wavelength blue light more than they do red, giving skim milk a bluish tint.

Answer 5

This is caused by the protein called Casein. Rich in calcium, Casein helps contribute to milk's white color.

Answer 6

Milk is white because of it's calcium content.

Answer 7

Actually, the milk is not in the white color, the white color is in the milk, and it comes that way from the teets.

Answer 8

Because it reflects the entire visible light spectrum back into your eye. Why it does that I have no clue.

Answer 9

So that you can get milkshakes of different colours.

Answer 10

B'coz it's not red in colour.
