Sulphur dioxide (SO2) is traditionally used as antioxidant and preservative in fruit and vegetable products, dried fruits, snack products and wine. However, SO2 and sulphites strongly reduce vitamin B1 uptake and bear risks for asthma patients.

The SO2SAY project will develop a strategy to replace sulphur dioxide  or its salts for almost all food products. This will promote Food Quality and Safety as well as consumer’s Quality of Life.
