Recent Advances in Omics Technology in Food Flavor

Area of Science:

• Food Science
• Biotechnology
• Analytical Chemistry

Background:

• Flavor is crucial for food quality and consumer acceptance.
• Traditional methods for flavor analysis have limitations in objectivity and mechanistic insight.
• Omics technologies provide high-throughput molecular profiling for food research.

Purpose of the Study:

• To review the application of omics technologies in food flavor research.
• To identify current limitations and propose future directions for mechanistic studies.
• To highlight the potential of integrated multi-omics and causal inference for flavor research.

Main Methods:

• Narrative literature review of genomics, transcriptomics, proteomics, metabolomics, and lipidomics.
• Discussion of single-omics versus multi-omics approaches.
• Introduction of a causal inference framework for omics data analysis.

Main Results:

• Omics studies have advanced flavor component identification but lack mechanistic depth.
• Single-omics approaches provide incomplete information on flavor regulatory networks.
• Multi-omics integration, intervention experiments, and AI are crucial for understanding causal flavor mechanisms.

Conclusions:

• Future food flavor research requires advanced multi-omics integration and causal inference.
• Artificial intelligence is key for analyzing complex omics datasets.
• Developing real-time analysis, data fusion strategies, and causal relationship exploration is essential.
