Researchers at Rothamsted Research in Harpenden, Hertfordshire, have made a groundbreaking discovery in the field of food safety. By utilizing Crispr genome editing, they have successfully developed wheat that can be used to make bread with reduced levels of acrylamide, a toxic compound classified as a probable carcinogen.The innovation lies in the reduction of free asparagine, an amino acid in wheat that converts into acrylamide when bread is toasted, fried, or baked. Field trials over two years demonstrated that gene-edited wheat can have significantly lower concentrations of free asparagine without impacting crop yields. This translates into lower acrylamide formation in food products, making toasted bread safer for consumption.In tests, bread and biscuits made from the edited wheat showed substantially reduced acrylamide levels, with some bread samples having concentrations below detectable limits even after toasting. The Crispr editing targeted the gene responsible for asparagine production, achieving a reduction of up to 93% in free asparagine in dual-edited lines.Compared to conventional methods that achieved a 50% reduction in free asparagine but resulted in a 25% yield penalty, the Crispr-edited wheat offers a more efficient and effective solution. Dr. Navneet Kaur, a lead researcher, highlighted the potential of Crispr technology to deliver precise, beneficial changes in crop genetics, emphasizing the importance of supportive regulatory frameworks to unlock benefits for agriculture and food systems.The UK has become a global hub for gene editing research since Brexit, with the Genetic Technology (Precision Breeding) Act of 2023 facilitating the development and marketing of genetically modified crops. However, the future of these advancements may be influenced by negotiations with the EU over sanitary and phytosanitary agreements.Prof. Nigel Halford, who led the study, noted that low-acrylamide wheat could help food businesses meet safety standards without compromising product quality or incurring major costs, ultimately reducing consumers' dietary exposure to acrylamide.
