Milk, a nutritious white liquid primarily sourced from cows and buffaloes for human consumption, is often referred to as the “complete food.” It comprises 87.2% water, 3.5% proteins, 3.7% fat, 4.9% sugar, and an array of vitamins and minerals. These components contribute to its status as a well-rounded nutritional source. It’s worth noting that in different regions around the world, people obtain milk from various animals, such as reindeer’s milk in northern Europe and goats’ milk in Middle Eastern countries.

Each of these nutrients within milk serves a unique purpose. Proteins promote growth and physical strength, sugar acts as a fuel source, and fats provide additional energy. Essential minerals like calcium and phosphorus aid in bone formation, while a variety of vitamins – A, B, C, D, E, K, and niacin – combat vitamin deficiencies and support overall health.

Milk’s rich history dates back over 5,000 years when humans discovered its many applications. Beyond its pure form, milk yields a plethora of by-products, including curd, butter, cheese, and more, all of which have become indispensable in our daily lives.

To maintain milk’s freshness, rapid cooling to 10 degrees Celsius within two hours of milking and maintaining this temperature during transportation is crucial. For safe consumption, it is recommended to pasteurize milk by boiling it once to halt the growth of harmful microbacteria, although excessive boiling can compromise its nutritional content.

In recent times, processed milk has gained popularity due to its perceived health benefits. The consumption of homogenized and skimmed milk has surged as these processes reduce or entirely remove fat content.
