Application of sequential injection analysis (SIA) to food analysis

For effective control of food quality, a laboratory should be able to analyse a large number of samples in an accurate, reproducible and quick way. As sequential injection analysis (SIA) is becoming an important tool for the automation of chemical procedures, this paper presents an overview of the applications of this emergent methodology to food analysis. SIA systems developed to date offer good characteristics for routine use and the analytical methods proposed show adequate precision and accuracy. In addition, the results obtained are in good agreement with those furnished by the application of the reference methods.
