Abstract Injecting chicken products with water has emerged as a considerably spread method for increasing the weights of the product in order to increase profits. Due to the huge number of products that are retailed daily, it is out of reach to test them with conventional methods for water injection. Here we present results for rapid screening of water amount in chicken filets done by electrical bio-impedance, a technique that is easy to implement, rapid, portable. Electrical impedance depends on structure and composition of the sample, and as such, its values correlate with water amount. We present results for values of electrical bio-impedance for 50 samples from the Dutch market and compare them with values of bio-impedance obtained with chicken filets injected with tap water, salty water, and with moisture retaining agents. Results demonstrate that, after proper calibration, bio-impedance is a convenient method for a rapid screening of meat products.
