    Question

    Macronutrients are important in which of the following process?

    1. Drowning process
    2. Cloning process
    3. Browning process
    4. Cooking process

    Hint:

    Change in the color of the food materials due to oxidation.

    The correct answer is: Browning process

      • The Browning process occurs in food materials due to the oxidation of the biomolecules present
      • This process can be divided into enzymatic and non-enzymatic reactions
      • The enzymatic reaction can be caused due to the activation of an enzyme called polyphenol oxidase 
      • The non-enzymatic reaction can be caused due to external factors like cooking (Maillard reaction or caramelization)
