New research from the University of Otago has revealed the best home storage methods to lengthen the shelf life of vegetables. Love Food Hate Waste, the national campaign to help New Zealanders reduce the amount of food they waste, partnered with the University of Otago to test storage practices for many common vegetables found in Kiwis’ refrigerators. The results, released today, show that simple techniques can lengthen the life of produce and dispels many urban myths around how best to store food.
