Abstract
Omega-3 polyunsaturated fatty acids (n-3 FAs) are essential nutrients and are considered effective in improving human health. Recent studies highlight the importance of the combination of n-3 FAs and polyphenols for limiting the oxidation of n-3 FAs and exhibiting synergistic beneficial effects. Herein, we developed a novel formulation technology to prepare oleogels that could be used for the codelivery of n-3 FAs and polyphenols with high loading efficacy and oxidative stability. These oleogels are made from algal oil with polyphenol-enriched whey protein microgel (WPM) particles as gelling agents via simple and scalable ball milling technology. The oxidative status, fatty acid composition, and volatiles of protein oleogels during accelerated storage were systematically assessed by stoichiometry and gas chromatography-mass spectrometry. These results showed that protein oleogels could overcome several challenges associated with the formulation of n-3 oils, including long-term oxidative stability and improved sensory and textural properties. The protein oleogel system could provide an excellent convenience for formulating multiple nutrients and nutraceuticals with integrating health effects, which are expected to be used in the care of highly vulnerable populations, including children, the elderly, and patients.
