BACKGROUND The consumption of omega‐3 fatty acids has many beneficial effects for human health, but the intake of foods rich in these fatty acids is not enough to achieve the recommended quantity per person and per day, and their direct addition in foods cause oxidation and unacceptable rancidity and off‐flavor. Taking account of all these aspects, this study was aimed to develop stable microcapsules of fish oil (omega‐3 polyunsaturated fatty acids) and lycopene (antioxidant) and to investigate their effect on different spreads. RESULTS The inclusion of different proportions of lycopene in fish oil did not show great benefits in the quality characteristics of emulsions and microcapsules. After the addition of fish oil and fish oil + lycopene microcapsules to dry‐cured ham and cheese spreads, no significant differences were found in the proximal composition and oxidative stability, whereas fatty acids composition and sensory analysis were influenced. The eicosapentaenoic and docosahexaenoic acids content increased with the fish oil content in both products, but it decreased significantly after storage in the cheese spreads. Addition of microcapsules did not significantly influence on quantitative–descriptive and acceptability sensory analyses in dry‐cured spreads, but it negatively affected the flavor of cheese spreading creams. CONCLUSION There is no need to add antioxidants to improve the stability of the fish oil microcapsules in the present study, which are appropriate as eicosapentaenoic acid and docosahexaenoic acid vehicles to enrich meat‐derived spreading creams. © 2019 Society of Chemical Industry
