Answer 2

Answer:

Alum is the odd one out because it is an inorganic mineral-based natural salt that is used as a preservative, astringent etc in food.

Explanation:

• Other substances like oil, sugar and honey are organic substances obtained from plant and animal sources that are consumed as food directly.
• Alum is a 'double sulfate salt' of metals like potassium, aluminium, sodium etc.
• They are acidic in nature and taste and so it is used as an astringent in pickling vegetables.
• It is also used in 'baking powder' and as 'acidulants' in food.
