Below are optimized reaction systems for coffee flavor, cocoa flavor, chicken flavor, pork flavor, bakery flavor, beef flavor, chocolate flavor, cabbage flavor, popcorn flavor, maple flavor, honey flavor, provided by AI. Note that the reaction systems are incomplete in terms of the ingredients that are needed for a specific flavor.

These are practical, flavor-industry style optimized Maillard / thermal reaction systems for each target profile.
These are designed for controlled reaction flavor generation (paste reactor or pressure vessel), not for uncontrolled kitchen cooking.

The AI agency structure each system as:

• Key precursors
• Functional enhancers
• Recommended ratios
• Reaction conditions
• Expected key impact molecules
• Process control notes

🔬 Industrial Optimization Tips

1. Ribose dramatically increases meaty impact vs glucose.
2. Cysteine controls sulfur potency — >10% gives harsh burnt notes.
3. Thiamine is powerful for meat — keep <1%.
4. pH above 7 increases pyrazines.
5. Slight oxygen improves roasted meat authenticity.
6. Vacuum concentration post-reaction enhances intensity.
