The book consists of ten sections. The first section provides an introduction to the topic and reviews the origin of FIA, including recent developments and future trends. The next six sections discuss the determination of additives. These sections are divided based on the official classification of additives according to function by the EU. In the final three sections, you will find a review of the determination of antioxidant capacity, antimicrobial effects, and acidity by FIA.
