Special Issue Information

Dear Colleagues,

The global demand for sustainable and nutritious edible oils is rapidly growing, driving innovation across the entire value chain. This Special Issue explores cutting-edge advancements in green extraction technologies (e.g., enzyme-assisted, supercritical CO2, ultrasound- and microwave-assisted methods, etc.) and novel oeaginous resources and their underutilized bioactive compounds (e.g., tocotrienols, vitamins, lignans and cyclopeptides, etc.). We also highlight advanced analytical techniques (e.g., omics, hyperspectral imaging, AI-driven assessment) and novel food industry applications (including functional foods, plant-based alternatives, and lipid-based delivery systems). Contributions on circular economy approaches (e.g., byproduct valorization), sustainability assessments (LCA, techno-economic analysis), and regulatory considerations for next-generation edible oils are also welcome. Studies emphasizing health benefits of unconventional oils (microbial, algae, insect-derived) and their endogenous bioactive compounds are particularly encouraged, as are papers on process intensification and optimization for preserving bioactive compounds. This collection aims to advance eco-friendly, high-value edible oils to address future food security and sustainability challenges.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Foods is an international peer-reviewed open access semimonthly journal published by MDPI.

China’s macadamia industry has expanded remarkably; however, a comprehensive understanding of the interaction between cultivar and geographical origin in shaping oil quality remains limited. This gap constrains the development of high-value products. To address this, we conducted a systematic and comparative evaluation of macadamia nuts and their pressed oils from 15 representative cultivars across Yunnan, Guangxi, and Guangdong. Our analysis encompassed physicochemical properties, fatty acid profiles, key minor components (tocopherols, squalene, and polyphenols), and antioxidant activities. Oleic acid (56.66–62.75%) and palmitoleic acid (12.24–18.73%) were the dominant fatty acids, with Yunnan oils exhibiting the highest unsaturated fatty acid content (80.86%). Multivariate analyses revealed that geographical origin was a more dominant factor than cultivar in shaping the overall compositional profile, particularly for the minor bioactive components. A strong positive correlation was established between antioxidant capacity and the contents of polyphenols, squalene, and tocopherols. The Guangxi A4 cultivar emerged as the premier material due to its superior fatty acid profile, high bioactive content (squalene: 329.01 mg/kg; tocopherols: 64.10 mg/kg), and potent antioxidant capacity. Our findings provide a scientific foundation for the selective breeding and origin-based standardization of premium macadamia oils in China. Full article
