- A. Carbon dioxide
- B. Flavor compounds and melanoidins ✓
- C. Ethanol
- D. Hydrogen peroxide
Why: The Maillard reaction produces flavor compounds and melanoidins, which contribute to the color and taste of cooked foods.

- A. They are not involved in the Maillard reaction
- B. They react with reducing sugars to form flavor compounds ✓
- C. They increase the water content of food
- D. They prevent browning
Why: Amino acids react with reducing sugars during the Maillard reaction to form a variety of flavor compounds and aroma molecules.
Q5. Which of the following foods is least likely to undergo the Maillard reaction?
- A. Grilled steak
- B. Steamed broccoli ✓
- C. Baked bread
- D. Roasted chicken
Why: Steamed broccoli is cooked at lower temperatures and with more moisture, making it less likely to undergo the Maillard reaction compared to grilled, baked, or roasted foods.
