Milk, whether liquid or powdered, is considered an essential food that is indispensable in the human diet. Each type has its own usage depending on its purpose, availability, and ease of storage. In this article, we will thoroughly explore the uses of liquid and powdered milk, their differences, advantages and disadvantages, and their roles in the food and medical industries, supported by accurate statistics and comparison tables, while highlighting the latest trends in the global market.
First: Liquid Milk
Uses:
- Daily Consumption: Liquid milk is consumed fresh as part of breakfast or between meals, providing an essential nutritional boost to start the day actively and enhance satiety.
- Cooking and Desserts: Used in preparing foods such as creamy soups, lasagna, pastries (croissants, pancakes), and white sauces (béchamel), adding a creamy texture and rich flavor.
- Hot and Cold Beverages: Added to coffee (latte, cappuccino), tea (milk tea), hot cocoa, and blended smoothies to enhance nutritional value and improve texture.
- Dairy Products: Used in manufacturing yogurts (Greek, flavored), fresh cream, soft cheeses (mozzarella, ricotta), hard cheeses (cheddar, parmesan), heavy cream, and buttermilk.
- Traditional Cooking: Used in preparing popular dishes like molokhia with meat or chicken, creamy chicken soup, custard, and caramel desserts.
Advantages:
- Rich Nutrient Content: One cup (240 ml) of whole liquid milk contains about 8g of protein, 300mg of calcium (around 30% of daily needs), and vitamins A, D, and B12.
- High-Quality Protein Source: Milk protein contains all essential amino acids necessary for tissue building and muscle health.
- Vitamins and Minerals: Provides vitamin D (essential for calcium absorption), vitamin B12 (important for nerve health and red blood cell production), phosphorus, and potassium.
- Relatively Easy Digestion: Compared to some other protein sources, milk contains natural enzymes that aid digestion.
- Immediate Use: Ready to drink or cook without any preparation or dissolving.
Disadvantages:
- Short Shelf Life: Once opened, must be consumed within 3–7 days and kept refrigerated between 1–4°C.
- Allergy and Intolerance: Some people suffer from milk protein allergy or lactose intolerance, requiring alternatives.
- Cost and Storage: Requires refrigeration and cooled transport, increasing logistic costs, especially in remote areas.
- Environmental Impact: Large-scale milk production is linked to methane emissions, water consumption, and agricultural
land use.
Second: Powdered Milk
Uses:
- Food Industries: Widely used in chocolate, biscuits, pastries, instant drinks, and diet products.
- Medical Field: Used in manufacturing nutritional supplements, infant formulas, and specialized medical formulations for malnutrition.
- Household Use: An economical and practical choice, reconstituted by adding water, ideal for areas with limited refrigeration.
- Emergency Preparedness: Due to its long shelf life, it’s used in emergencies, humanitarian aid, camps, and long trips.
Advantages:
- Long Shelf Life: Lasts 6–12 months without refrigeration.
- Ease of Transport and Storage: Lightweight and doesn’t require complex storage conditions.
- Lower Cost: More economical than liquid milk, making it preferred by many families.
- Versatile Use: Suitable for cooking or drinking after preparation.
Disadvantages:
- Preparation Needed: Must be dissolved in water at a specific ratio to maintain taste and nutritional value.
- Less Flavor: Some types lack the fresh taste of natural milk, especially non-fortified ones.
- Loss of Some Nutrients: Especially vitamin C and some natural enzymes during the drying process.
- Possible Sensitivities: Some commercial brands may contain additives or fillers affecting digestion or causing allergies.
