Japanese Ramen Simulator Broth Umami Formula: Ratio Theory & Live Calc Guide

Stock:Tare:Fat Golden Ratio & Umami Synergy Multiplier (USM)

60–70% stock, 15–20% tare, 10–15% fat emulsion is the synergy sweet spot. USM = 1.0 + 0.15×min(Glu,Ino)/100. Both Glu+Ino above 90 → USM=1.35.

  • 7h tonkotsu: Brix +2.1° / +12 emulsion / 80% collagen gelatinized (95°C×4h)
  • Kombu 60°C 60min: Glu +22 / Brix +0.8° / 100°C 48h+ fat cap → Aroma -15
  • 15ml tare in bowl bottom — dumping into stockpot costs Emulsion -0.18
  • Hold 86–92°C: Emulsion(T)=1.0 / <85°C=0.62 / >95°C=0.88
  • Calculator workflow: ① pick stock ② tare ③ noodle ④ temp slider → live Umami/Aroma/ROI

Full Umami Score Formula & ROI Margin

Umami = (Glu × Ino)^0.72 × USM × Emulsion(T) | ROI% = ((Price−Cost)÷Cost)×100

Suggested price = round(cost×3.2/10)×10. Example: ¥380→¥1,220→+221% ROI. Below 80°C: Umami -8, Aroma -12. Export PNG poster for the kitchen wall.

86–92°C Holding Pot Emulsion Maintenance Mechanism

  • 86–92°C: gelatin keeps fat in suspension — Emulsion=1.0
  • <85°C: fat separates → emulsion breaks → Aroma -22 → critic -2★
  • 88°C hold: batch 2×100L pre-open → valid 48h (spoils at 72h)
  • 100°C boil: over-emulsified → fat cap → rest 10s before service
  • Temp slider: drag 60–100°C to watch Emulsion factor update live
