INTRODUCTION TO WATER ACTIVITY Water activity (aw) is defined as the amount of water available for microbial (bacteria, yeast and mold) growth. Water activity is based on a scale of 0 to 1.0 with pure water having a water activity of 1.00. Usually products that contain lower percent moisture have lower water activities. For example, those products such as dried fruits, crackers and dried pastas have very low water activities. Those foods with lower water activities are quite shelf-stable in that they contain very little water available for microorganisms to use for growth.
