The PhD studentship is funded by the Horizon Europe Circular Bio-Based Europe Joint Undertaking (HORIZON-JU-CBE-2024) programme as part of a project “Marine Biomass Valorization for Food and Feed Innovation” (MARMADE). The successful candidate will join Dr Gaurav Rajauria and will be part of a highly motivated and diverse team of researchers at the BioREFINE Research Group based at the SUSFERM Centre for Sustainable Fermentation and Bioprocessing Systems for Food and the Bioeconomy; School of Microbiology; and School of Food and Nutritional Sciences at UCC, Ireland. Dr Rajauria’s research is interdisciplinary and will allow candidates to develop their skills in a variety of areas, including circular bioeconomy, biobased refineries, biomass valorisation, advanced pretreatment technologies, microbial fermentation, bioprocessing, biomanufacturing and bioanalytical science.Background and objectivesThe main objective of MARMADE is to develop a portfolio of innovative food and feed ingredients from marine biomass that are affordable, nutritious, safe, healthy and sustainable. The MARMADE project aims to develop sustainable, high-value food and feed ingredients from marine biomass, focusing on crustacean residues (shrimp shells and blue crabs) and seaweed. The key objectives are to 1) establish efficient biorefinery processes for extracting ingredients (pre/postbiotics, vitamins, peptides, oligosaccharides, fats, emulsifiers, and digestibility enhancers); 2) develop innovative food and feed prototypes with improved nutritional and sensory properties; 3) ensure compliance with safety, sustainability, and regulatory standards, paving the way for future market uptake. To achieve these objectives, MARMADE will leverage advanced technologies, including Deep Eutectic Solvents (DESs), Supercritical CO2 extraction, dynamic high-pressure processing (e.g., microfluidization, high-pressure homogenization), wet milling, screw pressing, ultrasonication, and cavitation, to optimize extraction efficiency and maintain the purity of bio-based food and feed ingredients. The project contributes to the Farm to Fork Strategy by enhancing the nutritional profiles of food products and aligns with the EU Bioeconomy Strategy by fostering bio-based cascading extraction processes. Additionally, MARMADE promotes environmental sustainability by integrating the Safe and Sustainable by Design (SSbD). The MARMADE project is a HORIZON EU project involving partners and industry collaborators from Ireland, Italy, Greece, Denmark, Spain and the United Kingdom, therefore the candidate would have an excellent opportunity to engage and build collaborations at the European levels.Key tasks in the PhD Studentship include:

• Establish advanced and sustainable biorefinery processes for the extraction of high-quality building blocks from marine biomass, implementing a zero-waste concept through a cascade approach
• Develop selective and tailored extraction technologies for marine biomass
• Enhance the efficiency of extraction technologies and ensure the recovery of targeted biomolecules in high purity, integrating innovative technologies and optimizing parameters.
• Produce high-quality ingredients, and scale up the processes from lab scale to pilot scale
• Complete PhD credits as per structured PhD program requirements as set out by University College Cork.
