Water Activity Testing
Water activity (aw) is a crucial factor in determining the shelf life, safety, and quality of food products. It measures the amount of free moisture available in a product that can support microbial growth, chemical reactions, and enzymatic activity. Accurate water activity testing helps food manufacturers control spoilage, ensure product stability, and comply with food safety regulations.
At AML, we use precision water activity meters to measure aw values across a wide range of food products. Our testing enables manufacturers to optimize formulation, packaging, and storage conditions, reducing the risk of microbial contamination and product degradation.
With AML’s water activity analysis, food producers can:
- Enhance product shelf life
- Improve microbial safety
- Meet regulatory requirements
- Maintain consistent product quality
Benefits of Water Activity Testing with AML
- Accurate Measurement: Our high-precision water activity meters provide reliable results across a wide range of food matrices.
- Shelf-Life Optimization: By controlling water activity, manufacturers can extend product stability and minimize spoilage due to microbial growth or chemical breakdown.
Frequently asked questions
Water activity (aw) measures the amount of free moisture in a food product that supports microbial growth. Unlike total moisture content, aw directly affects shelf life, spoilage risk, and product safety.
By accurately measuring aw, manufacturers can identify whether conditions are suitable for bacteria, mould, or yeast to grow. This helps optimise formulation, packaging, and storage to reduce spoilage and extend shelf life.
Any product prone to spoilage or requiring shelf-life stability, such as baked goods, dried fruits, meats, snacks, or ready-to-eat meals, should undergo water activity testing to ensure safety and quality.
