Omics technologies genomics, proteomics, metabolomics, and transcriptomics—are fundamentally reshaping the landscape of food science. By probing the molecular and biochemical makeup of foods with unprecedented precision, researchers can uncover detailed nutrient profiles and identify bioactive compounds that influence food functionality and health outcomes.This level of analysis is not merely technical; it has practical consequences. For instance, omics-based methods have become invaluable tools for verifying food authenticity and ensuring traceability, which are critical for maintaining quality control within the industry. Moreover, the integration of omics data with bioinformatics and systems biology enables optimization of food processing and the enhancement of functional food properties. Such integration also paves the way for developing personalized nutrition strategies, moving beyond generic dietary recommendations toward approaches tailored to individual needs.In summary, the advent of omics has initiated a transformative shift in food research and industry practices. These approaches are supporting innovation in food safety, authenticity, and nutrition, ultimately contributing to improved health outcomes and a more robust, transparent food system.
