High intake of sodium and low intake of dietary fiber are two major dietary risk factors for preventable deaths worldwide, highlighting the need and implementations for developing health foods with...
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
