The Formation

Aroma and flavor play pivotal roles in defining the quality of food and food products, significantly influencing consumer preferences and experiences. In recent years, there has been a rapid expansion in the biocatalytic production of fine chemicals, including flavors and fragrances, reflecting a growing interest in enhancing the sensory profiles of various products. Given the diverse structural classes to which flavors and fragrances belong, they present a complex and intriguing focus for both academic and industrial research endeavors. This section aims to provide an overview of the formation of aroma and flavor compounds, shedding light on the intricate biochemical processes involved in their synthesis. By exploring the mechanisms through which these compounds are generated, researchers can identify key factors that influence aroma and flavor characteristics, both before and after harvesting. The composition of food and food products is notably varied, holding significance for a wide range of industries such as food, feed, cosmetics, chemicals, and pharmaceuticals. In addition to detailing the diverse aroma and flavor compounds present in these products, this section also examines the chemical reactions that contribute to their development. Processes such as Maillard reactions, lipid oxidation, and the interactions between precursors and reaction products are scrutinized for their role in shaping the sensory attributes of food items. Furthermore, the mechanisms governing the formation of these components in foods involving yeast or bacteria-mediated production and metabolism are explored, providing valuable insights into the intricate pathways that lead to the creation of distinct aroma and flavor profiles in various food products.
