Have you ever pondered the contrasts between the food of ancient times and our contemporary culinary landscape? It’s a fascinating journey through time, filled with questions that tantalize the mind: Was salt more intense back then? Did the apples of yesteryears possess a flavor lost to the ages?

Yet, amidst this exploration of the past, a recent discovery has ignited fresh dialogue: century-old milk powder, originally intended for Antarctic explorers, now is the matter of the hour. This revelation prompts us to consider: How does the milk we savor today is different from the previous generations? Read below to find out what the new study reveals:

Recent findings published in the Journal of Dairy Science shed light on this intriguing question, revealing that despite the aggressive development in selective breeding and agricultural methods over the years, the milk of yesteryears and today share striking similarities.

Embarking on a voyage to the South Pole aboard the Nimrod ship in 1908, Ernest Shackleton’s British Antarctic Expedition was laden not only with dreams of exploration but also with provisions, including 1,000 pounds of whole milk powder, 192 pounds of butter, and cheese. Their journey left behind history frozen in time, including a lone container of ‘Defiance’ brand whole milk powder, discovered a century later during the Antarctic Heritage Trust restoration project.

Lead investigator Skelte G. Anema, DPhil, principal research scientist at Fonterra Research and Development Centre, Palmerston North, New Zealand, emphasized the significance of this discovery. He noted, “The Shackleton dried milk presents a unique opportunity to compare milk from over a century ago with modern counterparts, offering invaluable insights into the evolution of dairy production.”

Before modern advancements, milk powder production relied on a roller-drying process, distinctly different from today’s spray-dried methods. Dr. Anema explained, “Early twentieth-century milk powders underwent a roller-drying process, involving hot milk poured between steam-heated cylinders, resulting in dried milk sheets.”

To assess the evolution of milk, Dr. Anema and his team analyzed the composition and properties of the ‘Defiance’ milk alongside contemporary counterparts from Fonterra. Surprisingly, despite the temporal gap, the bulk components, protein and fat compositions, and mineral content exhibited remarkable resemblance.

Moreover, while the Shackleton samples revealed traces of lead, tin, and iron, attributed to storage conditions of the era, modern milk powder proved to be of improved quality and purity, accredited to advancements in production technology and hygiene standards.

However, there was a stark difference that emerged during the study, most importantly in aroma compounds and powder quality. The research favored modern varieties for their enhanced solubility and appearance.

Dr. Anema emphasized, “This Antarctic relic underscores the enduring importance of dairy in human nutrition, bridging generations with its rich protein content and adaptability for transport and consumption.”

Ultimately, this journey through time highlights the continuity of dairy’s role in nourishing humanity. It also brings to the surface the refining its production, ensuring its relevance in an ever-changing world. Whether in the frosty expanse of Antarctica or the modern kitchen, milk remains a timeless cornerstone of nutrition, linking past explorations with present-day sustenance.
