In this episode of Food Safety Matters, we speak with Dr. Carter [41:18] about:

• The basics of water activity, including how it is measured and how it differs from moisture content
• The influence of water activity on food safety and shelf life, and how water activity data can support the validation of shelf-life claims
• Ways manufacturers can incorporate water activity into their shelf-life and food safety testing, and during research and development when formulating products
• Regulatory expectations around water activity monitoring as part of validation and verification
• The realities of water activity measurement that make real-time, inline testing impractical with current technology
• How water activity monitoring can help mitigate food waste
• The importance of the statement, “water activity is the energy of water.”
