Polymer-cocktail edible aerogel templates for structuring omega-3-rich sardine by-product oil into stable oleogels.
Sardine by-product oil is a sustainable marine lipid resource rich in long-chain polyunsaturated fatty acids (PUFAs), yet its high oxidative susceptibility and poor physical stability limit direct food application. An alginate-carboxymethyl cellulose-gelatin-chitosan matrix was developed to structure PUFA-rich oil thro...
