Scientists have retrieved a sample of some of the oldest milk powder ever made in New Zealand.
The Defiance milk powder, made in 1907, was aboard the ship Nimrod as part of explorer Ernest Shackleton's first solo expedition to step foot on the South Pole, and remained preserved in the sub-zero temperatures for over a century.
A study examining the milk powder has found it has remarkably similar nutrients content to the milk powder produced today.
