| Sumario: | 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 leading to erroneous results in aw measurement. Various condiments and seasonings also contain volatile compounds which produced a significant effect on sensor performance. Some glycols were also found to contaminate the sensor during aw measurement. Copyright © 1984, Wiley Blackwell. All rights reserved |
