IFI Scoring Service

Know exactly which receptor axis is off — and by how much.

Submit any food product or concept brief. We run a full 8-axis Iyengar Flavor Index analysis and return a formal report with per-axis scores, receptor basis, and construct recommendations. Sensory language maps to receptor math.

What you send us

Product description

What it is, the target consumer, and what problem it is trying to solve. No NDA required at intake — we work from your brief, not your formula.

What is not working

The sensory language from your panel, the axis you think is off, or just 'it tastes flat.' The IFI will tell you which receptor channel that maps to.

Target or context

Are you designing for GLP-1 users, a specific heat profile, bitterness attenuation, kokumi enhancement? Optional but accelerates the analysis.

What you get back — all 8 axes

IFI-H

Heat / Pungency

TRPV1-normalized pungency score with onset, peak, and duration breakdown.

IFI-S

Sweetness

TRPM5 and T1R2/T1R3 receptor signal strength at measured thresholds.

IFI-U

Umami

mGluR4 / T1R1–T1R3 heterodimer response with synergy coefficient.

IFI-B

Zero-Bitter

TAS2R-family suppression score — how effectively bitterness is attenuated.

IFI-K

Kokumi

CaSR-mediated richness, mouthfeel, and duration signal.

IFI-C

Cool-Burn

TRPM8 / TRPV1 antagonist balance — the cool-heat continuum score.

IFI-P

Sharp / Prickling

TRPA1-channel electrophilic response, separate from TRPV1 heat.

IFI-A

Astringency

Polyphenol–protein precipitation signal via tannin and proanthocyanidin pathways.
