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.

A novel urea complexation technology was developed based on the agglomeration phenomenon induced by ambient-temperature agitation of a ternary system consisting of urea, water and fatty acid ethyl esters (EEs). The agglomeration phenomenon can be regarded as an intuitive indicator to judge the occurrence of urea complexation. Using docosahexaenoic acid (DHA) containing EE (DHA-EE) from Crypthecodinium cohnii oil as the substrate, key variables including agglomeration time, urea/DHA-EE ratio, water/DHA-EE ratio, and temperature were investigated. The urea complexation predominantly occurred within 15 min following agglomerate formation. Temperature in the range of 0–40°C exerted no significant effect on the yield of the non-urea-complexed fraction or its DHA content, enabling the operation to be conducted at room temperature without heating or cooling. Under unoptimized conditions, the proposed method effectively increased the DHA content of EE from Crypthecodinium cohnii oil from 40.73% to 89.87%. For EE from Schizochytrium sp. oil, the contents of DHA and docosapentaenoic acid were improved from 47.17% and 13.93% to 69.30% and 20.29%, respectively. Meanwhile, the contents of eicosapentaenoic acid and DHA in two EE form fish oils were enhanced from 18.26% and 11.76% to 34.86% and 22.96%, and from 13.30% and 57.24% to 15.66% and 68.68%, respectively. The present study provided a novel technical pathway for the efficient enrichment of polyunsaturated fatty acids. Full article
