She worked jointly with scientists at Kentville, Nova Scotia, who provided her with the dehydrated vegetables for further analysis in Ottawa, Ontario.

This was an important activity during the war years as many fruits and vegetables had to be dehydrated and shipped to Europe for the war effort.

As a result of her work the appearance and nutritional value of commercial dehydrated cabbages, carrots, potatoes and turnips improved markedly.
