Milk contains around 4.4% fat, and this fat is the reason for its oily appearance. The 'oiliness' of milk is due to tiny fat globules suspended in a water-based solution, forming an emulsion. The stability and appearance of this emulsion are affected by factors ranging from natural composition to modern processing techniques like homogenization.

Cow's milk contains a natural sugar called lactose, which makes up about 4.7% of its total composition by weight. However, the percentage of milk that is lactose is not static, varying significantly depending on the mammal species and how the milk is processed.

While it is a common kitchen shortcut, assuming that 1 milliliter (ml) of milk is equal to 1 gram (g) is incorrect for precise measurements. The truth is that milk is slightly denser than water due to its complex composition of fats, proteins, and other solids. This means that 1 ml of milk actually weighs a bit more than 1 g, a distinction that can be important for scientific applications and some baking recipes.

Did you know that commercial butter is typically composed of at least 80% milk fat, with the remainder being mostly water and milk solids? To truly understand its complex and rich character, it's essential to examine what are the active ingredients in butter beyond just its primary fat content.

Skim milk powder, also known as non-fat dry milk, typically contains a maximum of 1.5% fat, a significant reduction from the 3.25% found in whole milk. Despite this, it retains the essential proteins, carbohydrates, and minerals of fresh milk, making it a nutrient-dense dairy product.

With approximately 400 different types of fatty acids, milk fat is one of the most complex natural fats, derived from both a cow's diet and its internal metabolic processes. These fatty acids, primarily found as triglycerides, are the building blocks of milk fat and play a crucial role in its physical characteristics and nutritional value.

According to the USDA, 100 grams of salted butter contains a very low 0.02mg of copper, which is far less than 1% of the average adult's daily requirement. This means butter is not a meaningful source of the mineral, with the majority of copper found in milk being associated with the non-fat fraction rather than the milk fat itself.

The primary carbohydrate in milk is a naturally occurring sugar called lactose, which is synthesized in the mammary glands of mammals. This lactose provides an important energy source and affects the overall carbohydrate count, which remains consistent across different dairy milk fat levels.

According to the USDA, commercial butter must contain at least 80% milkfat. This statistic reveals that, no, butter is not just milkfat, but rather a complex water-in-oil emulsion comprising several components beyond its primary fat content.

While no single element can be classified as 'dairy,' cow's milk is famously composed of approximately 87% water, with the remainder being a complex mixture of fats, proteins, carbohydrates, and minerals. Its intricate chemical structure, rather than a single element, accounts for its diverse nutritional properties.
