In 1802, Russian doctor Osip Krichevsky developed the first modern method for producing dried milk. This innovation laid the groundwork for the commercial production of milk powder, which was initiated by Russian chemist M. Dirchoff in 1832. Dirchoff’s efforts marked a turning point in dairy processing, as dried milk began to gain traction as a practical and versatile product.
The mid-19th century saw further advancements that refined milk powder production. In 1855, T.S. Grimwade patented a new procedure for producing dried milk, which contributed to the evolving landscape of dairy technology. By 1872, the development of spray drying technology revolutionized the industry. Spray drying involves atomizing milk into a stream of hot air, rapidly evaporating the water and leaving behind fine milk powder particles. This method quickly gained popularity due to its efficiency and the superior quality of the powder produced compared to earlier methods like roller drying, introduced around 1902.
Spray drying eventually became the predominant method for milk powder production, owing to its ability to preserve the nutritional content of milk and extend its shelf life. The process involves preheating milk, concentrating it through evaporation, and then spraying it into a heated chamber. The result is a fine, dry powder that retains the essential nutrients of fresh milk.
Today, milk powder is a crucial ingredient in various food products, including infant formula, confectionery, and baked goods. Its development has had a profound impact on the dairy industry, providing a stable and convenient form of milk that can be easily reconstituted. As a result, milk powder remains a vital commodity in global food production and trade.
