Milk

What Is Milk?

Milk is a nutrient-rich liquid produced by mammals to feed their young; it is rich in calcium, protein, and vitamin B12. In cooking, “milk” generally means cow’s milk; goat’s and sheep’s milk are more often used to make cheese.

Stores sell varieties such as whole, reduced-fat, fat-free, lactose-free, and UHT (long-life) milk. Pasteurization kills harmful microorganisms while largely preserving the milk’s nutritional value.

Milk Nutrition Facts

Whole milk contains about 61 kcal of energy, 3.3 g of protein, and 4.8 g of carbohydrates (lactose) per 100 ml. It is especially rich in calcium and vitamin B2 (riboflavin); it is considered an important source of calcium for bone and dental health.

What Are the Benefits of Milk?

With its high calcium and protein content, milk is a notable food to include as part of a balanced diet. Studies have shown a relationship between regular consumption and bone density; however, these findings are not individualized treatment recommendations.

This is general information; milk is a food, not a substitute for medical treatment. People with lactose intolerance can consider lactose-free milk options.

How to Choose Milk

When choosing milk, check that the package is not swollen or damaged, review the expiration date, and choose a fat content you prefer.

• Carton or opaque packaging reduces vitamin loss compared with a clear bottle.
• Whole milk has a creamier texture, while reduced-fat milk feels lighter.
• People sensitive to lactose should choose options labeled lactose-free.

How to Store Milk

Opened milk stays fresh for 3–4 days in the refrigerator at about 4°C / 40°F. Unopened UHT milk keeps for months at room temperature; refrigerate it after opening. Freezing is not recommended because it changes the texture.

How to Use Milk in Cooking

Milk is drunk on its own, added to tea and coffee, and used as a cooking liquid in recipes such as rice pilaf and milk pudding. It is also the base for yogurt, cheese, and clotted cream.

How to Bring Milk to a Boil Without It Boiling Over

Heat milk over low to medium heat, stirring frequently, so it boils without sticking to the bottom or boiling over. Resting a thin wooden spoon across the rim of the pot slows the foam from spilling over.

What Recipes Use Milk?

Milk is the base for rice pudding (sütlaç), muhallebi, kazandibi, homemade yogurt, and cream, among other desserts and recipes. It is also used to thicken soups and sauces.

Frequently Asked Questions

What is milk good for?

Milk is rich in calcium, protein, and vitamin B12 and is a notable part of a balanced diet. It is a food and is not claimed to cure any disease.

Is whole milk or reduced-fat milk healthier?

Both can be part of a balanced diet; the choice generally depends on daily fat-intake goals. For a specific recommendation, consult a nutrition professional.

Why does milk curdle?

Milk curdles when exposed to an acidic substance (such as lemon or vinegar) or when it spoils, as its proteins coagulate. Milk that is no longer fresh should never be consumed.

Is lactose-free milk different from regular milk?

Lactose-free milk has been pretreated with the lactase enzyme to break down lactose; its nutritional value is close to that of regular milk, though it may taste slightly sweeter. It is suitable for people with lactose intolerance.

Can you freeze milk?

Yes, but fat and water can separate as it thaws and change its texture; for this reason, thawed milk is recommended for use in cooked recipes.
