3.7 Explain the advantages of using mycoprotein as a food source

HSW 12 The use of contemporary science and technological developments and their benefits, drawbacks and risks
HSW 13 How and why decisions about science and technology are made, including those that raise ethical issues, and about the social, economic and environmental effects of such decisions
Year 7 Describe some useful products arising from excretory processes from microorganisms, e.g. alcohol, carbon dioxide, antibiotics and methane.
Year 8 Explain how microorganisms can be used to produce a range of useful products, e.g. vinegar, yoghurt.
Starter: What is Quorn
Show students some pictures or packaging of Quorn products that you have collected or downloaded from the Internet. Ask students to identify what they contain, how they differ from meat products and how and why the mycoprotein has been prepared like that. Then ask how mycoprotein fits the phrase ‘microorganisms for food’.
Main: How mycoprotein is made (Lit)
Worksheet B3.21a provides a description of how mycoprotein is made. Students are asked to highlight different aspects of the text in different colours.
Plenary: Mycoprotein advantages
They should include the kinds of reaction they catalyse. Take examples from around the class and briefly revise the key point about each enzyme catalysing a different reaction because of the link between the enzyme active site and the substrate(s).
Main: Investigating chymosin
Worksheet B3.23b presents a practical investigation on the effect of chymosin on different types of milk. Full details can be found on the Teacher and technician practical sheet B3.23 (2).
Plenary: Traffic light questions (AfL)
Give students 2 minutes to write a question to ask about the key aspects of this lesson. Collect the questions and give each student a green, red or amber card. Ask a selection of the questions. For each question, students should hold the green card up if they are sure of the answer, amber if they might know the answer and red if they do not know the answer. Ask students who are sure of the answer, if it is clear that others are uncertain.
