Topic 2.5: Processing
Food processing is the method of transforming raw ingredients into consumable products through various techniques and methods. It encompasses everything from basic preservation methods like drying and freezing to complex procedures such as chemical modifications and the creation of convenience foods. The concept of sustainability suggests that the process should:
- be based on raw materials that can be produced on an ongoing basis without undue environmental, social, or economic damage;
- not be dependent on finite energy sources in the long term;
- produce products that will not be harmful for human health.
The key drivers for sustainable food processing encompass a mix of environmental, economic, social, and regulatory factors. These drivers motivate companies and stakeholders to adopt more sustainable practices in food production and processing.
Key drivers include:
With a growing global population, there is a push for food systems that are both sustainable and capable of feeding people efficiently without depleting resources or causing environmental damage.
National and international regulations, such as carbon reduction targets, zero-waste goals, and bans on certain harmful chemicals, push companies toward sustainable food processing.
Reducing greenhouse gas emissions from food processing and supply chains to address global warming, protecting ecosystems and biodiversity by adopting sustainable sourcing and production methods that limit habitat destruction, as well as efficient water use and wastewater treatment to reduce pollution and conserve resources.
Limiting the use of non-renewable resources (like water and fossil fuels), reducing pollution, and avoiding deforestation linked to food production.
Sustainable food processing focuses on minimising the environmental impact of food production, and tools like the Life Cycle Assessment can help in achieving this goal.
Growing consumer interest in healthier, minimally processed, and organic foods has led to the demand for cleaner production methods and transparent labeling.
