Food safety is a matter of great significance for the global population. Therefore, researchers have been developing and validating analytical methods to extract, separate and quantitate a variety of hazardous and nutritional analytes in various food commodities. Due to the complexity of food components, a suitable pretreatment method is required to eliminate matrix effects and lower the detection limit. Afterward, chromatography and mass spectrometry are powerful tools in the guarantee of food safety and quality. This book is the reprint of a Special Issue of Separations, “Advances of Accurate Quantification Methods in Food Analysis”, and provides an overview of recent trends in food analytical methods. Both novel sample pretreatment and detection techniques are covered, with the aim of accurate quantification. This Special Issue received nine contributions that covered the latest analytical methods, and focused on pesticides, mycotoxin, antibiotics, metal ions, organic selenium and anthocyanins.

In the search for a healthier diet and facing the uncertainties about the consumption of artificial additives, the scientific community has explored in the last years the potential of natural compounds, such as polyphenols, carotenoids, chlorophylls, essential oils, tocopherols, vitamins, polysaccharides, among others, obtained from the most diverse sources, such as plants and fungi, for the replacement of the artificial additives in food, which has made these compounds recognized as “natural additives”. In addition to being considered less harmful to health, and giving a certain functional property to a foodstuff, natural additives can also provide a beneficial synergistic effect in the food matrix. For the consumers, diverse studies have been showed that regular ingestion of bioactive compounds, that can be applied as natural additives, can be helpful for the prevention/treatment of several chronic and aging illnesses, such as cardiovascular diseases and neurological disorders. However, there is much to be researched on the viable use of bioactive compounds and to overcome their chemical limitations so that it can actually be used as natural additives in foods. This book addresses, through 18 scientific articles, some natural compounds with potential for use as preservatives, nutritional additives, coloring agents, flavorings, and various agents.
