Water Activity

Method Description

Water activity (aw) is a measure of the free water content available for microbial and chemical reactions within a substance. Represented on a scale from 0 to 1, it signifies the ratio of water vapor pressure in a product to the vapor pressure of pure water at the same temperature. A crucial parameter in food, pharmaceutical, and cosmetic industries, water activity influences product stability, shelf life, and safety. Higher water activity levels create a more conducive environment for spoilage and microbial growth, making accurate measurement vital for quality control and regulatory compliance.
