Flavor molecules
are commonly used in the food industry
to enhance
product quality and consumer experiences but are associated with potential
human health risks, highlighting the need for safer alternatives.
To address these health-associated challenges and promote reasonable
application, several databases for flavor molecules have been constructed.
However, no existing studies have comprehensively summarized these
data resources according to quality, focused fields, and potential
gaps. Here, we systematically summarized 25 flavor molecule databases
published within the last 20 years and revealed that data inaccessibility,
untimely updates, and nonstandard flavor descriptions are the main
limitations of current studies. We examined the development of computational
approaches (e.g., machine learning and molecular simulation) for the
identification of novel flavor molecules and discussed their major
challenges regarding throughput, model interpretability, and the lack
of gold-standard data sets for equitable model evaluation. Additionally,
we discussed future strategies for the mining and designing of novel
flavor molecules based on multi-omics and artificial intelligence
to provide a new foundation for flavor science research.
