Which of the following food items will not provide energy after it is consumed?

  1. Raw potato

  2. Cooked rice

  3. A slice of a fruit

  4. Groundnut
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Cutting also raises the respiration rate, which results in sugars inside produce being broken down and carbon dioxide released.
 This can result in faster spoilage as well as a change in the taste and texture of the produce. Lower temperatures help slow respiration, so pre-cut produce should be kept refrigerated.
The three factors that lead to nutrient loss are heat, oxygen, and light. Hence,  a slice of a fruit is the food items which will not provide energy after it is consumed.

So, the correct option  is 'a slice of a fruit'.

  3. Hemicellulose

  4. Soluble fibre
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
