Sensor Contamination with Organic Volatiles During Water Activity Measurements with an Electric Hygrometer
This work investigates sensor contamination of an electric hygrometer by organic volatiles during water activity (aw) measurement in foods and volatile‐containing model systems. Various aromatic and flavor chemicals in aqueous solutions, at a concentration of O.1‐0.5%, may contaminate the sensor lea...
