Food additives show technological, biological and sensorial functions.
Twenty-five classes of foods additives and their industrial functions are reported.
Detection of food additives by spectroscopy, chromatography and electroanalysis.
Analytical techniques used in the studies of food additives.
Perspectives in food additives analysis by analytical techniques are provided.
This work describes the 25 classes of food additives that contain about 230 compounds with technological, sensorial and/or microbiological functionalities. These compounds are added to foods at the processing, packaging and transport steps, to improve the standard of quality, durability and stability of the product and adjust the colour, smell and flavour attributes. Food industries need to follow national and international quality standards that establish the conditions under which food additives may be used, and the food safety is guaranteed by strict quality control. This review describes the analytical techniques used in identification and quantification of food additives in foodstuffs, highlighting the main characteristics of each method (spectroscopy, chromatography and electroanalysis), and indicating the advantages and disadvantages typical of the methods used. Perspectives of the chemical analysis in the food industries are also discussed.
