Q1. What is the primary chemical process that occurs during caramelisation?
- A. Hydrolysis
- B. Dehydration and fragmentation of sugar molecules ✓
- C. Fermentation
- D. Oxidation
Why: Caramelisation involves the dehydration and fragmentation of sugar molecules when heated, leading to the formation of complex compounds that give caramel its distinct flavour and colour.

- A. Water vapour
- B. Carbon dioxide
- C. Maltose ✓
- D. Furan compounds
Why: Maltose is a disaccharide formed during the breakdown of starch, not a byproduct of caramelisation. Caramelisation produces water vapour, carbon dioxide, and various furan compounds, among other substances.

- A. Sucrose
- B. Glucose
- C. Fructose ✓
- D. Lactose
Why: Fructose caramelises the fastest because it has a lower caramelisation temperature compared to sucrose and glucose, making it more reactive under heat.

- B. Sugar
- C. Water
- D. Air
Why: Salt can act as a catalyst in caramelisation by lowering the melting point of sugar, which can affect the rate and extent of caramelisation.
Q3. What happens to the colour of caramel when the cooking time is increased, assuming temperature is constant?
- A. It becomes lighter
- B. It becomes darker ✓
- C. It remains the same
- D. It changes randomly
Why: When the cooking time is increased at a constant temperature, the colour of caramel becomes darker due to prolonged exposure to heat, which enhances the caramelisation process.

- A. Type of sugar used
- B. Amount of water present
- C. Ambient light ✓
- D. Presence of acid
Why: Ambient light is not a factor that affects the colour of caramel. The colour is primarily influenced by temperature, time, type of sugar, and the presence of acid or other catalysts.
Q5. What effect does adding an acid have on the caramelisation process?
- A. It slows down caramelisation
- B. It has no effect
- C. It speeds up caramelisation ✓
- D. It stops caramelisation
Why: Adding an acid can speed up the caramelisation process by lowering the pH, which can influence the rate of the Maillard reaction and caramelisation.
