Water activity is a key quality metric in the food industry, as it affects food safety, shelf life, taste, aroma, texture, mouth feel and colour. By establishing acceptable water activity levels and then monitoring water activity at various points in the production process, food manufacturers can reduce costs and avoid reputationally damaging quality issues and expensive product recalls. Water activity is even more important today, as manufactures come under pressure to reduce salt and sugar content. Furthermore, if packaging is redesigned to reduce or eliminate the use of plastics, the management of water activity plays a crucial role in maintaining food safety and shelf life.
