In the mid-19th century, French scientist Nicolas Appert, renowned for his contributions to food preservation, refined the process further. Appert’s technique involved boiling milk to remove its water content and then drying the remaining solids. While innovative, this method was inefficient and produced a lower-quality product, limiting its widespread adoption.
The late 19th century marked a turning point with the invention of the spray drying method by American inventor Samuel R. Percy. Spray drying revolutionized milk powder production by introducing a highly efficient technique. Milk was sprayed as a fine mist into a chamber of hot air, where the water evaporated almost instantly, leaving behind fine, uniform particles of milk powder. This method significantly improved the product’s quality and scalability, making milk powder more practical for commercial use.
Advancements in technology throughout the 20th and 21st centuries have further optimized the milk powder production process. Modern spray drying facilities now incorporate sophisticated controls and energy-efficient systems, ensuring consistent product quality while minimizing environmental impact. Additional processes, such as instantization, have been developed to make milk powder more soluble in water, enhancing its usability.
Milk powder has become a critical component of the global food industry. It serves as a vital ingredient in infant formulas, dietary supplements, and an array of processed foods, including chocolates, bakery items, and beverages. Its long shelf life and ease of transport make it indispensable in regions with limited access to fresh milk or stable refrigeration.
Today, the global milk powder market continues to expand, driven by growing demand in developing economies and innovations in dairy technology. The product’s enduring relevance underscores its role in addressing food security challenges and supporting nutritional needs worldwide.
