Explanations: answer key for all 10 questions

Q1: Which reaction between sugars and proteins browns bread crust and steak?
Answer: Maillard reaction
It creates hundreds of flavor compounds.
Q2: What happens when sugar is heated alone until it browns?
Answer: Caramelization
It starts around 160 °C for table sugar.
Q3: Which protein network gives bread dough its stretch?
Answer: Gluten
Kneading develops gluten strands.
Q4: What kind of mixture is mayonnaise?
Answer: An emulsion
Egg yolk lecithin keeps oil and water mixed.
Q5: What do yeasts produce during bread fermentation?
Answer: Carbon dioxide and alcohol
The alcohol bakes off.
Q6: Which chemical makes chili peppers hot?
Answer: Capsaicin
Milk helps cool the burn.
Q7: What scale measures chili heat?
Answer: Scoville scale
Wilbur Scoville created it in 1912.
Q8: What happens to egg proteins when cooked?
Answer: They denature and set
Heat unfolds and links proteins.
Q9: Which bacteria turn milk into yogurt?
Answer: Lactic acid bacteria
They produce lactic acid.
Q10: Why does mint feel cool?
Answer: Menthol triggers cold receptors
It is a chemical trick.

Food Chemistry Challenge – The Science of Cooking

Cooking is chemistry in action. Heat triggers reactions that change texture, flavor and color. The Maillard reaction browns toast and roasted meat, while caramelization turns sugar into golden caramel.

Ingredients have chemical roles. Gluten gives bread structure, eggs set when their proteins denature, emulsifiers like lecithin hold mayonnaise together and yeast and bacteria ferment bread, cheese, yogurt and pickles.

Our senses respond to food chemistry too. Capsaicin makes peppers taste hot and menthol makes mint feel cool. Understanding food chemistry helps chefs create better dishes and keeps food safe.
