Gastrointestinal Structuring of Agro-Industrial Dietary Fibres: From Green Extraction to Predictive Engineering

Objective

Dietary fibre is a critical yet underexploited component of functional food systems, with well-documented roles in gut health, satiety regulation and chronic disease prevention. However, the functional performance of fibre ingredients depends critically on particle size, hydration behaviour and gelation capacity, properties that are highly sensitive to extraction method yet rarely characterised in an integrated, pipeline-driven framework. Gastro-Fib addresses this gap through a 48-month international staff exchange programme uniting 20 partners across 15 countries, built around the original PSHG (Particle Size–Hydration–Gelation) framework. The consortium systematically links green extraction design (WP2) to physicochemical characterisation (WP3), intragastric behaviour (WP4), bioactivity assessment (WP5), pilot-scale food validation (WP6) and sustainability benchmarking (WP7), creating a closed-loop pipeline from agro-industrial side-stream to market-ready fibre ingredient. Eight structurally diverse fibre sources are investigated using emerging green extraction technologies including microwave-assisted extraction (MAE), ultrasound-assisted extraction (UAE), enzyme-assisted extraction (EAE), deep eutectic solvents (DES), ionic liquids (ILs) and biosolvents. Sustainability is embedded as a co-equal design parameter through integrated life cycle assessment (LCA), techno-economic analysis (TEA) and social LCA conducted in line with the EC's Safe and Sustainable by Design (SSbD) framework. A total of 373 person-months of secondments (360 EU/AC funded, 13 FAPESP (BR) -funded) across 87 researchers generate bidirectional knowledge flows between 12 academic and 8 non-academic partners, to enable direct translation of scientific outputs into industrial exploitation, IP protection and market uptake strategies targeting the EU dietary fibre ingredient sector.
