Tuesday 5th May 


Task 1 – Everyone needs to have a go at this task!

  • Read Maillard Reaction Explanation (SCROLL DOWN!)
  • What do you think is the most important information here to help someone understand the Maillard Reaction?
  • Read Explanation Features (These are also below, just keep scrolling!)Highlight and RAINBOW COLOUR Maillard Reaction Explanation to show any of these features. 

(Remember to RAINBOW COLOUR you need to colour each feature a different colour and then find and colour them on the text)




Maillard Reaction Explanation



The Maillard Reaction is a chemical reaction that happens to some food when it is heated. 


It happens when the food reaches a temperature between 140°C and 165°C. (Normal room temperature is about 18°C)


When the food reaches this temperature, two types of chemical that are in the food react with one another. The two types are carbohydrate molecules (a sugar wrapped up in a starch) and amino acids. 


These two chemicals form an unstable structure which undergoes further changes. This produces hundreds of different by-products. These result in hundreds of different aromas and flavours. 


The reaction is named after the French scientist, Louis-Camille Maillard who first discovered it in 1912.


The Maillard Reaction is the reason that toast, biscuits and cooked meat have a different flavour and appearance when they have been cooked.
