Eduqas GCSE Food Preparation and Nutrition (C560): The science of food (Area 4) overview

Area 4 of Eduqas GCSE Food Preparation and Nutrition (specification C560) is the science of food: why food is cooked, how heat moves into it, and the chemical and functional changes that happen to protein, carbohydrate and fat. This page maps the area and links to a focused answer page for each part. It is also the science behind the NEA Food Investigation.

The science of food content

Why food is cooked and heat transfer

The reasons for cooking and the three methods of heat transfer (conduction, convection, radiation). See Why food is cooked and heat transfer.

Functional and chemical properties of protein

Denaturation, coagulation, foam formation and gluten formation. See Functional and chemical properties of protein.

Functional and chemical properties of carbohydrate

Gelatinisation, dextrinisation and caramelisation. See Functional and chemical properties of carbohydrate.

Functional properties of fats and emulsification

Shortening, aeration, plasticity and emulsification, and the role of emulsifiers. See Functional properties of fats and emulsions.

Raising agents

Chemical, biological, mechanical and steam raising agents and the gas each produces. See Raising agents.

This area applies the nutrients from the principles of nutrition to what happens during cooking.

How this topic is examined

The science of food is assessed on the written paper (Component 1), which is 1 hour 45 minutes, worth 100 marks and 50% of the GCSE. Questions ask you to explain a named process with its conditions and a food example, often as a 4 to 6 mark extended response. The same science underpins the NEA Food Investigation, where you test how ingredients behave.

How to study the science of food

1. Learn each process as a chain. Name the process, the conditions, what happens, and a food example.
2. Drill the high-value terms. Gelatinisation, denaturation, coagulation, gluten formation, caramelisation, dextrinisation, emulsification and the raising agents.
3. Always give a food example. Pair gelatinisation with a sauce, gluten with bread, emulsification with mayonnaise.
4. Use your experiments. The Food Investigation gives you ready-made worked examples for the exam.
5. Write in sentences. Explanation marks reward clear cause and effect, not single words.
