Recent advances in investigating odor-taste interactions: Psychophysics, neuroscience, and microfluidic techniques

•Odor-taste interactions influence flavor perception at molecular-levels is unknown.•Synergistic effects of olfactory and taste perception can reduce salt/sugar intake.•Cross-modal interactions in the brain were proved by EEG and fMRI.•Microfluidics offer high throughput/in vitro sensory models to study interactions.
