When looking at the overall density of milk it is worth noting the density of water, fat and so-called solid non-fats. How density aids separation of cream and milk While not huge differences, but whole milk at 38.9☌ has a density of 1.023 kg/L. As the temperature increases so the molecules move further apart and the liquid becomes less dense. Whole milk’s (producer milk) density is 1.035 kg/L when the temperature is 4.4☌. The following chart shows milk density values under varying temperatures for different types of milk: When you mix and match the various elements of milk to create a different formula this will have an impact on the density. You may also see the density of milk presented in a slightly different manner (using the same figures):. We will use the following figures to calculate the density of milk:. The basic formula for calculating the density of milk is:

Density of milk: how to correctly calculate it The higher the water content the lower the density of the milk. Protein and lactose (but not fat) are denser than water so the lower the water component in comparison, the higher the density of the milk. We will now take a look at the density of milk which will vary in line with the ingredients – compared to the water content.

Lactose (milk sugar) approximately 4.5%.

The exact ingredients in cow’s milk will vary but tend to be in the following range:. However, it is one of the most nutritious foods available and part of the diet of billions of people around the world.Īs cow’s milk is by far and away the most popular type of milk in the Western world, we will focus on this when looking at ingredients and density.

In reality, milk can be anywhere up to 90% water with the rest a mixture of proteins, fats, and lactose (milk sugar). To many people, milk is just a white fluid that has the look and texture of water but feels a little 'thicker'. What is the breakdown/density of cow’s milk? Additionally, the whole conundrum of the US and the Imperial Gallon makes the simple question of 'what is the weight of a gallon of milk' so complicated. What makes the question of density per unit of weight tricky, is the fact density changes depending on the temperature and pressure. Below you can see the density equation and the table with Milk Density values, including those for whole, semi-skimmed, and skimmed milk, depending on temperature. Density is the amount of substance in a unit, per volume of substance.
