![]() ![]() The volume of milk is ½ pint equal to 236 ml or 0.000236 m 3.256.6 g (the mass of milk with carton) − 11.9 g (the mass of the carton) = 244.7 g (mass of milk).I also determined the density of milk myself. When you skim off the surface, some of the fat, the denser portions remains and the milk is denser. When milk is left to stand long enough, some separation will occur because of density differences.Ĭream or milk fat is lighter in density than water and floats on the surface of un-homogenized milk. As you go towards the surface it creates layers of decreasing density. As the lighter milk fat rises to the surface, the density changes. The fat thus collected is called "cream" and the milk deprived of fat is called "skimmed milk"or "skim milk". Then, fat can be collected or skimmed from the milk. Since fat has a lower specific gravity and therefore is "lighter" than the milk serum, fat globules rise to the milk surface. Low-fat milk typically has 1 percent or 2 percent fat. If the fat content is lowered to 3.25 percent, the milk is sold as whole milk. It makes up about 5 percent of milk's content. ![]() Lactose is a kind of sugar found only in milk and gives milk its sweet taste. Fat supplies taste and texture, and vitamins A, D, E, and K, as well as certain fatty acids that the body is unable to produce. It typically contains about 3.5 to 5 percent fat, which is dispersed throughout the milk in globules. Cow milk contains approximately 87% of water, 3 to 4% protein, 4 to 4.5% fat, and approximately 4.5% milk sugar (lactose). The remaining 10 percent consists of the major nutrients needed by the body for good health, including fats, carbohydrates, proteins, minerals, and vitamins. Most milk is composed of 80 to 90 percent water. The major source for commercial production and consumption is from cows. We drink the milk produced from a variety of domesticated mammals, including cows, goats, sheep, camels, reindeer, buffaloes, and llama. People enjoy drinking milk in its natural form and also use it to make a wide range of food products, including cream, butter, yogurt, cheese, and ice cream. Milk is a very nutritious and versatile food. The following table gives the density of various fluid dairy productsĪs a function of fat and solids-not-fat (SNF) composition: "With all of this in mind, the density of milk varies within the range of 1027 to 1033 kg m(-3) at 20° C. ![]() May 29, 2002.ĭairy Chemistry and Physics.
