Phytochemicals Course, MODULE 9 — Culinary Applications, Cooking Method Matrix
Activity: Fill in the Cooking Method Matrix
A sensory‑ecological activity for mapping how different cooking methods change plant chemistry, flavor, and bioavailability
Students choose foods, apply different cooking methods, observe sensory shifts, and reason through the underlying chemistry.
1. Choose Your Plant Samples
Select 3–5 foods representing different phytochemical classes:
- Carotenoid‑rich: carrot, tomato, squash
- Polyphenol‑rich: berries, greens, herbs
- Sulfur‑rich: garlic, onion, broccoli
- Lignan‑rich: flaxseed, sesame
- Saponin‑rich: quinoa, chickpeas
- Aromatic herbs: basil, rosemary, mint

2. Choose 3–5 Cooking Methods
Examples:
- Raw
- Boiled
- Steamed
- Roasted
- Sautéed
- Fermented
- Blended
- Crushed / ground
- Infused in fat
- Infused in water (tea, broth)

4. Sensory Observation Prompts
A. What changed in color?
(Think pigments: carotenoids intensify with heat; chlorophyll dulls; anthocyanins shift with pH.)
B. What changed in aroma?
(Volatiles released? Terpenes brightened or softened?)
C. What changed in taste?
(Sweetness, bitterness, pungency, acidity, umami.)
D. What changed in texture?
(Fiber softening, water loss, emulsification.)
5. Phytochemical Interpretation Prompts
A. Did the cooking method release or activate compounds?
(Heat, fat, grinding, crushing, fermentation.)
B. Did the method reduce or destroy any compounds?
(High heat, long boiling, oxidation.)
C. Did the method change solubility?
(Fat‑soluble vs. water‑soluble compounds.)
6. Bioavailability Prompts
A. Did this method increase absorption?
(Fat pairing, heat, grinding, fermentation.)
B. Did this method decrease absorption?
(Leaching into water, enzyme destruction.)
7. Ecological & Culinary Meaning Prompts
A. Why might traditional cuisines use this method for this food?
(Flavor, preservation, digestion, cultural symbolism.)
B. How does this method align with the plant’s ecological role?
(Defense compounds softened? Aromatics amplified?)
8. Final Reflection
What patterns did you notice between cooking method, sensory changes, and phytochemical behavior?
Think about:
- Heat vs. raw
- Fat vs. water
- Mechanical force vs. whole form
- Fermentation vs. fresh
