Summary
This comprehensive review examines recent advances in the recovery of bioactive phytonutrients — including tocopherols, phytosterols, polyphenols, and carotenoids — from by-products and waste streams generated during the industrial refining of edible oils. Published in a leading food science review journal, it surveys and critically evaluates emerging extraction and purification technologies, likely including membrane filtration, supercritical fluid extraction, and adsorption methods, within the context of circular economy principles. The paper makes a contribution to the growing literature on reducing industrial food-processing waste while simultaneously generating high-value nutraceutical or functional food ingredients.
UK applicability
The UK has an established edible oil processing industry, and findings are applicable to efforts by UK manufacturers and policymakers to align with circular economy targets under the UK Resources and Waste Strategy. Recovered phytonutrients could have commercial relevance for UK functional food, nutraceutical, and supplement sectors.
Key measures
Phytonutrient types and concentrations (e.g. tocopherols, sterols, polyphenols, carotenoids); extraction yields; valorisation efficiency; waste stream composition
Outcomes reported
The review likely reports on the types, concentrations, and bioactivities of phytonutrients recoverable from edible oil refining waste streams, and evaluates extraction, purification, and valorisation technologies. It probably also assesses the economic and sustainability implications of integrating these approaches into a circular or zero-waste bioeconomy framework.
