Special Issue Information

Dear Colleagues,

Lipids in food encompass a diverse range of components, including neutral lipids (such as triacylglycerols), complex lipids (such as phospholipids and ceramides), and various other lipid compounds. Recently, functional lipids have garnered significant attention in the development of health-promoting materials, with research highlighting their antioxidant, anti-inflammatory, and immune-modulating properties.

Moreover, nutraceutical lipid derivatives with tailored physicochemical properties can be developed through structural modifications using chemical or enzymatic methods, following purification to enhance lipid purity. These derivatives hold potential as alternative therapeutic agents for the prevention and management of diseases. As research continues to advance in understanding the properties of lipids, this Special Issue will address their synthesis, separation, analysis, and utilization in drug delivery systems (DDSs). For instance, lipid-based formulations—such as gels, nanoparticles, liposomes, and microemulsions—can be used to regulate drug release rates, thereby supporting sustained-release drug delivery systems.

To achieve these goals, the analysis of food materials using advanced instrumental techniques such as HPLC-MS/MS, NMR, IR and GC-MS will play a crucial role in determining the composition, content, and characterization of lipids. Contributions on innovative or improved methods for lipid extraction and purification are also welcome. Furthermore, submissions are encouraged on topics including the identification of naturally occurring lipids, structural modifications via enzymatic or chemical processes, and efficient separation techniques for enhancing lipid purity.

Additionally, this issue seeks studies on lipid oxidation inhibition through antioxidants, the development of ways to preserve taste and texture while reducing calorie content, and methods for isolating, purifying, and concentrating functional lipid ingredients from food resources. These advancements are pivotal for the food industry and lay the foundation for further exploration in the field of food lipids.

We invite researchers to contribute to this Special Issue of Foods by sharing insights and findings on advances in food lipids.

Maple (Acer spp.) seeds are potential sources of fat-soluble nutrients and bioactive compounds, yet they remain comparatively understudied. This study compared six market-derived Acer seed types by quantifying phospholipids (PLs), fatty acids, carotenoids, and phytosterols, and by evaluating total phenolic content (TPC) and DPPH radical scavenging activity in methanolic extracts. Total phospholipid contents varied markedly among samples (17.94–295.87 mg/100 g), with phosphatidylcholine (PC), phosphatidylethanolamine (PE), and phosphatidylinositol (PI) as the predominant classes. Fatty acid profiles were dominated by oleic acid (C18:1) and linoleic acid (C18:2), and nervonic acid (NA; C24:1) was consistently detected in all samples at 0.17–1.88 g/100 g (4.55–7.89% of total fatty acids). β-Sitosterol ranged from 16.58 ± 1.41 to 37.46 ± 1.62 mg/100 g. Carotenoid composition varied among the tested samples, and Jeju red maple showed the highest provitamin A potential, including the exclusive detection of α-carotene and the highest retinol activity equivalent. Antioxidant indices also differed significantly among samples (TPC: 317.89–897.12 mg GAE/100 g; DPPH: 81.37–93.27%), but TPC was not consistently proportional to DPPH activity, suggesting contributions from non-phenolic constituents. Pearson correlation analysis further showed exploratory co-variation patterns among the measured variables across the tested samples. Overall, the tested market-derived Acer seed materials exhibited marked compositional diversity and antioxidant potential, supporting their further evaluation as candidate functional food, nutraceutical, and value-added plant lipid resources.
