Abstract

The MEDALP project addresses critical challenges in Mediterranean food systems by developing sustainable, cost-effective, and culturally tailored plant-based alternative protein products (PBAPs) that combine microalgae and legumes. Over 36 months, MEDALP will: (1) design and validate low-water, low-energy microalgae cultivation systems—including rotating attached-growth reactors that will reduce freshwater use by 90 %, harvesting costs by 50 % and geothermal-powered ponds that will target at least 15 % increase in biomass productivity and 20 % reduction in drying energy consumption (2) optimize green cell-disruption and extraction methods (mechanical milling, ultrasound, enzyme-assisted techniques, fermentation or combinations) to achieve at least 80 % protein yields with 25 % lower energy inputs; (3) characterize nutritional quality, digestibility, and safety of algae–legume blends using in vitro digestion, toxicological and immunological assays, targeting at least 80% protein digestibility and minimal allergenicity; (4) formulate and sensorially validate at least three consumer-preferred PBAP lab prototypes (dairy, meat and fish alternatives, “edible inks” for snacks and bakery products) with more than 85% acceptability in Mediterranean panels; (5) perform ex-ante Life Cycle Assessments to benchmark environmental performance against conventional proteins, aiming for less than 5 kg CO₂-eq kg⁻¹ protein; (6) conduct cross-country consumer research (n = 6 000) to map neophobia as well as food values and guide target-specific communication campaigns; and (7) valorize residual biomass into hydrochar, biochar, biopesticides, biofertilizers and high-in-fiber edible ingredients closing nutrient loops in a circular-bioeconomy framework.

MEDALP integrates expertise from biotechnology, bioengineering, food science, food chemistry, clinical, immunology, bioinformatics, environmental modeling, and social sciences across seven countries, embedding FAIR-compliant open-science practices and gender-aware analysis. By delivering pilot-scale demonstrations (TRL 5–6), open-access data and protocols, and stakeholder co-creation platforms, MEDALP will empower SMEs, farmers, policymakers and consumers to adopt innovative PBAPs, advance PRIMA’s goals for resilient, healthy diets, and contribute to the European Green Deal and Farm-to-Fork strategies.
