Water Activity in Foods: Fundamentals and Applications is a one-of-a-kind reference text that brings together an international group of food scientists, chemists, and engineers to present a broad but thorough coverage of an important factor known
The importance of water activity (aw) in food systems cannot be overemphasized. Throughout history water activity in food has been controlled by drying, addition of sugar or salt and freezing. These methods prevent spoilage and maintain food quality. Water activity is the ratio of the ...
Water is also recognized in the food industry as being critical for the stability of most products. aw exerts a decisive influence on such phenomena as change in colour, taste and aroma, food poisoning and spoilage (shelf life), loss of vitamins… Controlling the Water Activity of a Product:...

Controlling Water Activity in Food explores a traditional method of preserving corn by drying. In this virtual laboratory, learners test water activity levels of dried corn and explore how they change under three different storage environments. The interactive guides users through the theory and prac...

Water activity (a w ) is defined as a w =p/p o where p and p o are the partial pressures of water above the food and a pure solution under identical conditions respectively. The tightly bound water has no tendency to escape from a food as a vapor and therefore exerts no partial ...
