The Universitat Jaume I has obtained, within the Spanish Plan for Scientific and Technical Research and Innovation 2021-2023, more than two hundred and fifty thousand euros to develop two research projects related to food protection, one that seeks the development of a new biodegradable polymer for packaging and another that will apply advanced techniques of high-resolution mass spectrometry for the identification of organic compounds in environmental and food samples.

The project "Development and evaluation of a biodegradable polymer film for flexible and biocircular food packaging applications", led by researchers Luis Cabedo Mas and José Gámez Pérez of the Polymers and Advanced Materials (PIMA) group and funded with 176,660 euros, seeks to develop a plastic formulation based on biopolymers with properties suitable for use in the flexible food packaging sector.

To this end, it will use biopolymers of non-petrochemical origin, both commercial and those developed within the project, as well as additives and compatibilising agents to produce, by means of reactive extrusion, a material suitable for the manufacture of thin films with suitable mechanical properties. This film will be used to develop different flexible packaging concepts based on foil heat-sealing and paper-plastic composites.

The recyclability (mechanical and organic) of the plastic film, as well as of the packaging concepts developed in the project, will also be analysed. Biodegradability will be studied both under composting conditions and in the environment, with the aim of understanding the mechanisms behind this biological process, and a full examination of the sustainability of the designed systems will be carried out by means of life cycle, cost, social impact and circularity studies of the proposed solutions.

The study "Advanced high resolution mass spectrometry techniques for the discovery and identification of organic compounds in environmental and food samples" led by researchers Juan Vicente Sancho Llopis and Tania Portolés Nicolau from the Analytical Chemistry in Public Health and Environment (Q-AMS) group and funded with 90,750 euros, aims to make use of chromatography, both gas and liquid, coupled to ion mobility-high resolution mass spectrometry (IM-HRMS) for the determination and identification of contaminants and residues in environmental waters and food as well as biomarkers of quality and authentication of premium foods.

In the first part of the work, innovative solutions are sought in the field of clean and healthy aquatic ecosystems and safe food. To this end, both water normally used for irrigation (groundwater, surface water and urban wastewater) will be analysed in order to predict their environmental impact, as well as foodstuffs representative of the Mediterranean diet to assess their safety. The compounds to be studied will be more conventional: pesticides, persistent organic compounds (POP) and toxins of natural origin but also emerging pollutants, especially frequently used drugs, antibiotics and personal hygiene products, among others.

The second part of the research, framed within the metabolomics platform implemented in the research group, will focus its study on the field of Spanish premium foods, both from the point of view of their quality and their authentication, in order to find markers that add value to their quality brand image. Both studies will use advanced scientific instrumentation from the University Institute of Pesticides and Water, of which the researchers also form part, and from the Central Scientific Instrumentation Services of the Universitat Jaume I.

**STATE RESEARCH PLAN**

The research staff of the Universitat Jaume I of Castelló has obtained 4.17 million euros from the Spanish Research Agency, two more than in the previous call, for the development of 38 new research projects of the State Plan for Scientific, Technical and Innovation Research 2021-2023, which focuses its objectives on the most strategic sectors for recovery, such as health, ecological transition and digitalisation.

The success rate (number of projects approved out of the total submitted) stands at 70% (the national average is 50%) and with an average funding per project of around 110,000 euros and 14 more projects than in the previous edition. With the 2021 call, the Universitat Jaume I has reached 23.7 million euros of funding for R&D&I since the launch of the Spanish Strategy for Science, Technology and Innovation a decade ago.
