Article Abstract
The consumption of omega-3 fatty acids and phytosterol promotes the reduction of cholesterol and triacylglycerol levels. However, such compounds are susceptible to oxidation, which hampers their application. The objective of this work was to coencapsulate echium oil, phytosterols and sinapic acid (crosslinker/antioxidant), and incorporate the obtained microcapsules into yogurt. The microcapsules were evaluated for particle size, accelerated oxidation by Rancimat, and simulation of gastric/intestinal release. The yogurts were assessed for morphology, pH, titratable acidity, color, rheology and sensory analysis. The microcapsules (13-42μm) promoted protection against oil oxidation (induction time of 54.96h). The yogurt containing microcapsules, presented a pH range from 3.89 to 4.17 and titratable acidity range from 0.798 to 0.826%, with good sensorial acceptance. It was possible to apply the microcapsules in yogurt, without compromising the rheological properties and physicochemical stability of the product.

Interest in indigenous and dual-purpose chicken breeds for sustainable poultry farming is growing. Additionally, incorporating local feed resources into their diets may enhance the nutritional value of their products while reducing environmental impact. This study investigated the ability of oil (EO), rich in stearidonic acid (SDA, 18:4n-3) compared to linseed oil (LO) and high in alpha-linolenic acid (ALA, 18:3n-3), to increase long-chain n-3 polyunsaturated fatty acids (LC-PUFAs) in breast meat.

This study investigates the production of plant protein hydrolysates from defatted grape seed flour and barley spent grains, by-products of wine, beer and whiskey industries, using limited hydrolysis with subtilisin or trypsin. The hydrolysates were characterized by protein content, molecular weight, antioxidant capacity, interfacial adsorption, dilatational rheology, and interfacial conformational changes using synchrotron radiation circular dichroism. Physical and oxidative stability of 5 % echium oil-in-water emulsions (pH 7), stabilized by the hydrolysates, were studied during seven days of storage.

Poultry can be a sustainable source of eicosapentaenoic acid (EPA, 20:5n-3) and docosahexaenoic acid (DHA, 22:6n-3) through the bioconversion of dietary alpha-linolenic acid (ALA, 18:3n-3). However, this process is currently limited by the high n-6/n-3 ratio in poultry diets affecting the competition between n-6 and n-3 fatty acids (FA) for the same biosynthetic enzymes, and the rate-limiting Δ6 desaturase which act at both, the first and final steps of DHA synthesis pathway. Echium plantagineum oil (EO) is an unusual source of stearidonic acid (SDA, 18:4n-3) which bypasses the first Δ6 desaturase step potentially increasing n-3 long-chain polyunsaturated fatty acids (LC-PUFA) synthesis.

This study investigated the oxidative stability of instant fried noodles by applying free and microencapsulated black hollyhock extracts (BHE) and borage extracts (BE) (BE, BHE, ME-BE and ME-BHE). At first, the BE and BHE were encapsulated with whey protein and maltodextrin at a 90:10 ratio through a spray dryer. After evaluating particle characteristics (including anthocyanin content, zeta potential, polydispersity index (PDI), particle size, and morphology), they were added to the noodle formulation (wheat flour 78.
