Researchers from Griffith University, Australia, examined the growing consumer demand for nutrient-rich tropical fruits and the challenges in maintaining desirable fruit flavor in commercial breeding programs. The study highlights a critical issue: while breeders often focus on improving agronomic traits such as yield and disease resistance, flavor quality may be unintentionally compromised, leading to reduced consumer satisfaction. Despite the known importance of sugars, acids, and volatile organic compounds in determining fruit flavor, there is limited knowledge about the specific combinations of these metabolites that appeal to consumers, especially for tropical fruits. The study emphasizes the need for integrating objective, quantitative analysis of flavor compounds into breeding programs rather than relying solely on human sensory evaluations. By identifying the key metabolites that define flavor preferences, the development of selective genetic markers could be enhanced using integrated omics approaches, targeting the biosynthetic pathways of flavor compounds. This review explores the current progress in creating tools for defining and selecting consumer-preferred flavor profiles, aiming to support the breeding of new tropical fruit cultivars that meet market demands while maintaining high-quality taste attributes.
