Special Issue Information

Dear Colleagues,

Many studies support the potential bioactivity of specific natural or processed functional foods due to their content of a plethora of bioactive ingredients, such as probiotics, fibers, antioxidants, polyunsaturated fatty acids, vitamins, peptides, and phytochemicals. In this vein, in recent years, the food industry has focused on the development of novel processed foods that are rich in bioactive compounds, such as fortified and enriched foods, with potential nutritional or health claims, alongside the use of novel technologies. These novel functional products, consumed as part of a balanced diet in the form of ready-to-eat products, may help prevent nutrient deficiencies and promote health.

This Special Issue focuses on the further investigation of new technologies for the development of novel functional foods (encapsulation, fortification, lyophilization, etc.) to increase the bioactivity, stability, and bioavailability of the bioactive compounds and their possible effect on biomarkers of human health. We welcome papers that report the latest evidence-based results on the development, bioactivity, and bioavailability of novel functional foods. Animal experiments, clinical trials, and epidemiological studies, as well as in vitro studies, meta-analyses, and review articles, are also welcome.

Note: All the guest editors are members of FOODBIOMES, which is a new distributed research infrastructure of the agri-food sector established in Greece that aims to offer world-class research, education, and innovation services exploring the impact of microbiome applications in food systems and the development of novel functional foods.

Acorns represent an underutilized source of forest biomass with potential for producing edible oils and bioactive compounds. This research compared lipid fractions from pedunculate oak (Quercus robur L.) and northern red oak (Quercus rubra L.) collected in Poland, examining how different extraction methods influence oil yield and quality. Oils were extracted using Soxhlet with hexane, cold hexane extraction for both species, and mechanical pressing for Q. rubra. Fatty acid profiles analyzed by GC-FID facilitated calculation of lipid quality indices. Oxidative stability was assessed through isothermal PDSC, and total phenolics, flavonoids, and antioxidant activity (DPPH, ABTS) were measured in acorn extracts. Q. rubra produced more oil than Q. robur regardless of extraction method, but Q. robur oils exhibited significantly higher PDSC oxidation times (τon, τmax). Pressed Q. rubra oil showed higher acid and peroxide values compared to solvent-extracted oils. Fatty acid composition was predominantly influenced by species rather than by extraction method, as confirmed by multivariate analysis, which indicated species as the main driver of variability. Overall, these results highlight a trade-off between oil yield and oxidative stability, suggesting acorns as a promising, species-dependent oil resource. Full article
