Category: Resource Management · Effect: Strong effect · Year: 2025
Incorporating extracts from citrus waste into food processing can significantly mitigate the formation of acrylamide, a toxic compound.
Design Takeaway
Designers and food technologists should explore the use of citrus waste extracts and other agrifood waste derivatives as functional ingredients to reduce acrylamide formation in heat-processed food products.
Why It Matters
This research highlights a practical application for food waste valorisation, transforming a disposal problem into a solution for improving food safety. It offers designers and food technologists a sustainable approach to enhance product quality and consumer health.
Key Finding
Using materials derived from agricultural waste, especially citrus byproducts, can effectively lower the levels of acrylamide formed during food heating processes, though the effectiveness depends on several factors.
Key Findings
- Agrifood-sourced materials like antioxidants, dietary fibre, pH modulators, and asparaginase are effective in reducing acrylamide.
- Citrus waste is a predominant material for acrylamide mitigation.
- The efficiency of waste materials is influenced by concentration, food composition, and processing conditions.
