Hint 1

Read the label: under which heading are E304 and E307b listed?

Hint 2

Which gas is filled in chip packets to stop oxidation?

Step-by-step solution

Each step shows the marks it earns, as an examiner would award them. Checked by an independent re-solve from the question paper.

  1. The label shows that E304 and E307b are antioxidants. They stop the fats in the biscuits from being oxidised and turning rancid.

    ½ mark

  2. Food packets are flushed with nitrogen, an unreactive gas, for the same purpose: it keeps oxygen out and prevents rancidity. Answer: (C).

    ½ mark

Answer: Nitrogen, option (C)

Where the marks are

  • Identifies the additives as antioxidants and links nitrogen flushing to preventing rancidity; chooses (C) (1 mark)
