of milk<br />
Milk is an excellent source of calcium, phosphorus, and vitamin D, essential for bone health, and provides complete protein containing all nine essential amino acids. It also supplies B vitamins, particularly riboflavin and vitamin B12, and bioavailable nutrients that support various physiological functions.
About
Milk is a nutrient-dense liquid secreted by mammary glands of lactating mammals, most commonly obtained from domesticated cattle (Bos taurus), though also from goats, sheep, buffalo, and other species. Cow's milk is the most widely consumed globally and typically contains approximately 87% water, 3.2% protein, 3.6% fat, and 4.6% lactose. The composition varies by breed, diet, and stage of lactation, with variations in fat content, protein structure, and mineral concentration affecting both flavor and culinary properties.
Milk's flavor profile ranges from subtle and creamy to more pronounced depending on the source animal, feed, and processing method. Raw milk exhibits more complex flavors influenced by the animal's diet, while pasteurized milk has a more neutral, consistent profile. Whole milk contains the full fat content, semi-skimmed contains approximately 1.5-1.8% fat, and skimmed milk contains less than 0.5% fat.
Culinary Uses
Milk serves as a foundational ingredient in cuisines worldwide, functioning as a beverage, cooking medium, and base for numerous derivatives. It is essential in sauce-making (béchamel, crème anglaise), baking, custards, puddings, and dairy-based preparations. Milk is heated to produce yogurt, cheese, butter, and cream, each with distinct culinary applications. In cooking, milk is used to tenderize meat, enrich soups and stews, create smooth textures in sauces, and provide a subtle sweetness to both savory and sweet dishes. Different fat percentages affect results: whole milk creates richer sauces, while lower-fat versions suit lighter preparations.
