Food Production: Biotechnology
Biology: AQA GCSE Higher, topic 7.5.2
Biotechnology
Biotechnology is the use of biological processes to develop or make products. Modern biotechnology techniques include:
Growing microorganisms for food
- Mycoprotein is a food source that is high in protein and fibre, low in fat and suitable for vegetarians.
- It is produced by growing the fungus Fusarium in vats called fermenters under aerobic conditions and using glucose syrup as a food source.
- Eventually, the biomass is harvested, before finally being purified and used to make meat substitutes.
Genetic modification
- Genetically modified crops have the potential to provide more food, including more nutritious food.
- Golden rice, for example, is genetically modified to contain a molecule that helps make vitamin A.
- If distributed effectively, golden rice can play a significant role in reducing the large number of cases of vitamin A deficiency worldwide.
