For several years, It’s Fresh!, a food freshness technology company with offices in the UK and US, has been developing special filter papers that slow down the ripening process of fruit and vegetables when inserted into packaging.
Currently, the papers are used by fruit and vegetable growers and suppliers to keep produce fresh during transport and on supermarket shelves, but last month, London restaurant Canteen started trialling the papers in their kitchen. The experiment was a success, as chefs reported throwing away far less gone-off produce.
According to Simon Lee, the co-founder of It's Fresh the filters are used on fruit at harvest and can offer 2-4 days of extra shelf life.
