The aroma of soft drinks is a core attribute that determines product competitiveness and consumer acceptance. The retention and release behaviors of aroma compounds are regulated by the interactions between the matrix components and aroma compounds. Although significant progress has been made in the identification of aroma compounds in soft drinks, the regulation of soft drink aromas remains challenging because of these complex interactions. This review first introduces the compositional characteristics of typical matrix components in soft drinks and then discusses the interaction mechanisms between aroma compounds and proteins, carbohydrates, sweeteners, lipids, and organic acids in detail and systematically. The characterization methods for matrix-aroma interactions, along with the effects of environmental conditions (such as temperature and pH) and processing technologies (such as sterilization and microencapsulation), are also discussed. Finally, the current challenges are discussed, and future research directions are proposed.
