Abstract
The addition of encapsulated bioactive compounds in food matrices allows obtaining foods with improved nutritional characteristics. In this study, chia oil (a source of omega-3) and astaxanthin were encapsulated in beads and added to commercial yogurt. Particles formulated using only sodium alginate (100SA) or mixed with whey protein aggregates (25WPA75SA) with incorporated chia oil and astaxanthin were added to yogurt. The stability of bioactive compounds added was evaluated, and consumer-based sensory analysis was applied using both a hedonic scale and Check-All-That-Apply method. The content of bioactive compounds in yogurts did not change after 28 days of storage. Yogurts exhibited good acceptability and the terms with high positive impact in all samples were sweet, pleasant flavor, smooth, creamy, pleasant particles, pleasant, and easy to swallow. Yogurt added with 25WPA75SA beads showed greater acceptance indicating that this matrix may be a good option to improve the consumption of astaxanthin and omega-3.
