Materials & Equipment

Lesson 1: Introduction: food processing & technology

Duration: 50 minutes

Starter Activity (5 minutes)

Quick Recall

Write down everything you already know about food processing & technology. Then check against the key terms: key terms from food processing & technology. Use a mini-whiteboard or paper.

Main Content (35 minutes)

Parent/Teacher Guide:
Before lesson: Read the script below. Pre-teach key vocab: key terms from food processing & technology.
If stuck: Re-read the revision notes (link above), then break the content into smaller steps.
Extension: See the Stretch & Challenge ideas in Lesson 4.
Teaching Script (35 mins):
Mins 0-5 - Hook: "Today: food processing & technology. By the end you will be able to answer exam questions on it unaided. It connects to the rest of Food Preparation and Nutrition because the ideas here recur across the spec."
Mins 5-20 - Direct Instruction: Work through the core ideas below one at a time; after each, ask your student to explain it back in their own words.
Mins 20-30 - Guided Practice: Model the worked example together, then let your student attempt the first practice question with guidance.
Mins 30-35 - Independent Practice: 2-3 practice questions from Lesson 3 below, with immediate feedback.
First Look

Start with the revision notes summary, then attempt: explain the key ideas of food processing & technology

Plenary (5 minutes)

Check Out

Your student states one thing they learned and one question they still have about food processing & technology.

Lesson 2: Core Concepts: food processing & technology

Duration: 50 minutes

Starter Activity (5 minutes)

Review Previous Lesson

Quick recap: write 3 key points from Lesson 1 on food processing & technology. Check them against the notes below.

Main Content (35 minutes)

Key Fact: Primary processing converts raw food materials into basic ingredients: milling wheat into flour, pasteurising milk, refining sugar cane, and slaughtering and butchering animals.
Key Fact: Secondary processing converts primary-processed ingredients into more complex products: making flour into bread, milk into cheese, flour and sugar into biscuits, potatoes into crisps.
Key Fact: Food additives are substances added to food for a specific purpose: preservatives (extend shelf life), colourants (improve appearance), flavourings (enhance taste), emulsifiers (mix oil and water), stabilisers (maintain texture).
Key Fact: Additives are given E numbers when approved for use in the EU; some consumers prefer additive-free foods due to health concerns (e.g. hyperactivity linked to some colourants).
Key Fact: Fortification adds nutrients to food to improve public health: folic acid in flour, vitamins A and D in margarine, calcium in plant milks, iron in breakfast cereals.
Key Fact: Genetic modification (GM) alters an organism's DNA to produce desired traits: pest-resistant crops, vitamin-enriched rice (Golden Rice), herbicide-tolerant soya. GM food is controversial.

Starter Activity (5 minutes)

Quick Recall

Recall the key terms: key terms from food processing & technology. Define each in one sentence.

Main Content (35 minutes)

Parent/Teacher Guide: Let your student attempt each question alone first, then compare with the model answer. Award method marks for correct working even if the final answer is wrong.

Work through the practice questions on the revision notes page for this topic.

Main Content (35 minutes)

Extended Answer

Extended question: Full-Mark Response Explain the difference between primary and secondary food processing, giving examples. Discuss the role of food additives and evaluate their use in processed foods. (8 marks) <div class="

Primary processing converts raw food materials into basic usable ingredients. Examples include milling wheat into flour, pasteurising raw milk, refining sugar cane into sugar, and slaughtering and butchering animals into cuts of meat. Secondary processing transforms these primary ingredients into more complex finished products: flour into bread, milk into cheese or yoghurt, potatoes into crisps, and cocoa beans into chocolate. Food additives are substances added during processing for specific purposes. Preservatives (e.g. sulphur dioxide in dried fruit) prevent microbial growth and extend shelf life, reducing food waste. Colourants improve visual appeal (e.g. annatto in cheese), flavourings restore taste lost during processing, and emulsifiers (e.g. lecithin) allow oil and water to mix in products like mayonnaise and ice cream. Additives have benefits: they make food safer (preservatives prevent food poisoning), more convenient (longer shelf life), and more appealing. However, there are concerns: some synthetic colourants have been linked to hyperactivity in children, excessive preservatives may cause allergic reactions, and the ease of using additives enables ultra-processed foods

Exam Tips: Always distinguish clearly between primary and secondary processing with specific examples. | When discussing additives, categorise them by function (preservatives, colourants, etc.) and give examples. | For GM food, present both the potential benefits (nutrition, yield) and concerns (health, environment, ethics). | Learn the definition of fortification and be able to give at least two real examples used in the UK.
Common Errors: ✗ All food additives are artificial and harmful. ✓ Many additives are natural (e.g. citric acid from citrus fruits, beetroot red colouring). All approved additives have been tested for safety, and are only permitted at levels far below any harmful dose. ✗ E numbers are all artificial chemicals. ✓ E numbers include natural substances too — E300 is vitamin C (ascorbic acid), E101 is riboflavin (vitamin B2). The E number simply means the additive has been approved for EU use. ✗ GM food is dangerous to eat. ✓ There is no consistent scientific evidence that approved GM foods are harmful to eat. Concerns focus more on environmental impacts (cross-pollination, biodiversity) and ethical issues rathe
Stretch & Challenge (Grade 8-9):
  • Synoptic links: explain how food processing & technology connects to another Food Preparation and Nutrition topic you have studied
  • Real-world: research one real-world use or example of food processing & technology
  • Critical: "What are the limitations of the models used in food processing & technology?"
