Potential of Impedance Spectroscopy for Real-Time Assessing of Food Quality

Reliable information about food state and freshness throughout production processes and until consumption is very important for product quality, consumer safety and export of goods. Regulations worldwide protect consumers and encourage the production of safe, nutritious and affordable aliments. Several measurement methods for food quality assessment can be used in the laboratory e.g., chemical analysis, mechanical methods, optical methods, x-ray measurements and nuclear magnetic resonance. Even if they are precise, these methods remain useless for real-time application. © 1998-2012 IEEE.
