The Mediterranean diet, well known for its health benefits, is characterized by high consumption of plant-based foods, along with low to moderate amount of seafood and animal products. In contrast, life in the 21st century is marked by a fast-pace, making the consumption of
nutritious foods challenging, as ultra-processed foods have become the default option for their convenience, despite their negative impact on health.
The MedSnack project appears as an alternative, by developing a minimally processed and sustainable ready-to-eat snack, incorporating the nutritional value of the Mediterranean diet by using olives and dates, sweetened with honey, and enhanced with natural colorants and
bioactives. The wrapper of the snack will be produced from algae-based polymers, infused with volatile protective compounds obtained from the bioresidues of olive and date trees, through innovative and sustainable processes like ultrasound and microwave assisted extractions.
A key innovation of MedSnack is its sustainable and circular solution by using Mediterranean products and their residue to create a ready to eat, healthy, and sustainable product. This project is included in a wider funded PRIMA project, FoWRSaP – Agro Food Waste Recovery: New Processing Technologies for Food Safety and Packaging, aimed at adding value to residues to develop new packaging and improve food safety in several food products.
