What is Milk?
Milk, in its natural form, is a liquid produced by mammals, most commonly cows in India. Fresh milk comes in various forms: full-fat, skimmed, toned, and even plant-based varieties like almond or soy milk. Fresh milk is packed with essential nutrients like calcium, protein, vitamins A and D, and healthy fats.
Nutritional Benefits of Fresh Milk
Fresh milk is a great source of:
- Protein: Aids in muscle repair and growth.
- Calcium: Essential for healthy bones and teeth.
- Vitamins: Especially vitamins A and D, which support vision and immunity.
- Fat: Natural fat content supports energy needs, though it varies depending on the type of milk (e.g., full-fat vs skimmed).
How is Milk processed?
Milk processing involves several steps to ensure its safety, quality, and shelf life. Here’s an overview of how milk is processed and how it is typically consumed:
1. Collection
Fresh milk is collected from cows (or other mammals like buffaloes, goats, etc.) on dairy farms. The milk is then transported to processing plants, where it undergoes several treatments to make it safe for consumption.
2. Pasteurisation
One of the first steps in milk processing is pasteurisation. This involves heating the milk to a specific temperature (typically 63°C for 30 minutes or 72°C for 15 seconds) to kill harmful bacteria and pathogens while preserving its nutritional value. After pasteurisation, the milk is rapidly cooled.
3. Homogenisation
Homogenization is a mechanical process that breaks down the fat molecules in milk, ensuring that they are evenly distributed throughout the liquid. This prevents the curds from separating and floating to the top, giving the milk a uniform texture and consistency.
4. Fortification
Some types of milk, particularly in India, are fortified with additional vitamins and minerals, such as Vitamin D, to improve their nutritional content. This is particularly common in milk sold as “toned” or “double-toned.”
5. Packaging
Once the milk has been processed, it is packaged into cartons, bottles, or pouches for distribution. The packaging is designed to protect the milk from contamination and preserve its freshness.
6. Refrigeration and Distribution
Processed milk must be stored in cool conditions to prevent spoilage. It is distributed to retail outlets, such as grocery stores, supermarkets, and local dairies, where consumers can purchase it.
How is Milk Consumed?
- As a Drink: The most common way to consume milk is as a drink, either chilled or heated. It is often consumed with tea or coffee or on its own as a healthy beverage.
- In Cooking and Baking: Milk is a staple ingredient in many Indian dishes, from gravies and curries to sweets like kheer, gulab jamun, and peda. It is also used in smoothies, milkshakes, and desserts.
- In Tea and Coffee: Milk is commonly added to tea and coffee, enhancing their taste and providing a creamy texture.
- In Dairy Products: Milk is also used as the base for many other dairy products such as curd (yogurt), butter, ghee, paneer (cottage cheese), cheese, and ice cream.
In summary, milk is processed through pasteurisation and homogenization to make it safe and convenient for consumption. Once processed, it is used in various ways in daily diets, both as a beverage and as a key ingredient in numerous culinary preparations.
What is Milk Powder?
Definition of Milk Powder and Its Production
Milk powder, also known as powdered milk, is made by removing the moisture from fresh milk through a drying process. This results in a shelf-stable product that can be stored without refrigeration for long periods. There are two main types:
- Full cream milk powder: Retains the fat content of whole milk.
- Skimmed milk powder: Made from non-fat milk. It is ideal for those looking to reduce fat intake.
Types of Milk Powder Available in India
- Instant milk powder: Dissolves quickly in water and is the most commonly used in homes and businesses.
- Non-instant milk powder: Takes longer to dissolve and is typically used in the food processing industries.
History of Milk Powder
Early Concepts (13th Century):
- The idea of preserving milk dates back to the Mongol Empire, where Marco Polo reported that the Mongols used sun-dried milk to carry on long journeys. It was more of a milk paste or cake rather than powder.
Modern Invention (19th Century):
- 1832: Russian chemist M. Dirchoff is credited with inventing the first modern method of making milk powder by evaporating milk.
- 1855: T. S. Grimwade in the UK patented a method for drying milk, improving quality and shelf life.
Industrial Production (Late 1800s):
- Milk powder became more widely produced and used in the late 19th century, particularly for use in the military and by travellers, due to its convenience and long shelf life.
