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.

2. Read more explanations and answer questions.

  • Choose a Chilli Challenge to work with; these are all linked below:

 

3. EXTRA TASK: Watch and compare two videos

  • Watch these two video explanations of the Maillard Reaction. (Click the links)
