Brits Could Be Eating 3D-Printed Chocolate and Lab-Grown Foie Gras by 2035
A groundbreaking new report from the Food Standards Agency and Food Standards Scotland has highlighted the innovative food technologies most likely to transform British plates over the next 10 to 15 years. By 2035, experts predict that UK consumers could be regularly consuming lab-grown foie gras, edible insects, and even 3D-printed chocolate as these novel foods become mainstream.
Lab-Grown Meats and Edible Insects Leading the Way
Among the most imminent innovations are foods grown from animal and plant cells in laboratory settings. Products such as steak, chicken, and duck foie gras are already undergoing rigorous risk assessments by regulators, with two specific items currently being evaluated. This cellular agriculture promises to revolutionise protein production while addressing ethical and environmental concerns associated with traditional farming.
Edible insects represent another significant shift, with four species already available in the UK under temporary arrangements while safety assessments are completed. These can be sold as whole insects or processed into powders for incorporation into familiar foods. However, the FSA has issued a crucial warning: allergen proteins found in crustaceans are also present in edible insects, meaning individuals with shellfish allergies could experience similar reactions. This underscores the importance of comprehensive safety evaluations for these novel food sources.
Vertical Farming and Future Innovations
Some technologies are already establishing themselves in the market. Vertical farming, which involves growing crops like lettuce in highly-controlled indoor environments with precise nutrient delivery, is becoming increasingly mainstream. This method enables year-round production and reduces resource consumption compared to traditional agriculture.
Looking further ahead, the report identifies several emerging technologies that could reshape food production. These include using plants as "tiny factories" to produce specific food ingredients and "gas fermentation" techniques that employ microbes to convert captured carbon dioxide into single-cell proteins for human consumption. While still in developmental stages, these approaches hold promise for sustainable food systems.
3D-Printed Foods and Personalised Nutrition
The report also examines more conceptual innovations like 3D-printed foods, which would allow manufacturers to construct edible items layer by layer from printers. Although not expected to reach broad markets within the next five to ten years, this technology could enable the creation of personalised foods for individuals with specific dietary needs, such as those who have difficulty swallowing for medical reasons.
Dr Thomas Vincent, deputy director of innovation at the FSA, emphasised the regulatory challenges posed by these advancements. "The food system is always evolving, and as a regulator, we need to keep pace with that and keep pace with the industry so that we can help ensure that new products are safe," he stated.
Comprehensive Safety Assessments Essential
Dr Vincent outlined the multifaceted approach required to evaluate these novel foods. Safety assessments must ensure that new production methods meet stringent food safety and hygiene standards, while also considering allergenicity, nutritional content, and potential long-term health impacts. This includes examining not just the composition of products, but also their production processes.
"What we do is a really thorough, holistic safety assessment that looks at things like allergenicity, but also at toxicology, at microbial contamination of foods," he explained. "It looks at acute risks, so things that might happen once you eat food, but also at chronic risks, so there’s longer term potential risks, and that includes things like carcinogens, for example."
This comprehensive evaluation is particularly crucial given existing concerns about the health effects of ultra-processed foods. The FSA aims to ensure that any lab-grown alternatives replacing traditional meats provide comparable nutritional benefits that consumers expect.
