Nutrition & composition

Moisture content

Measure water content for composition, specifications and development comparisons.

A composition measurement

Moisture testing quantifies water content under the chosen method conditions. The method should suit the food, including volatile ingredients or other characteristics that affect the measurement.

Comparison projects

A change in moisture can affect texture and the concentration of other components. Compare development versions on a consistent reporting basis and identify whether the result is as received or on a dry basis.

Sampling matters

Keep samples sealed and representative of the product being evaluated. Record the processing and package state so that moisture gain or loss is not mistaken for a formulation difference.

Read it with water activity

Moisture content and water activity provide complementary information. Neither alone describes every stability or microbial question.
