ABSTRACT We designed a chicken-meat hamburger enriched with ω3 polyunsaturated fatty acids and cooked by sous-vide. The chicken meat used came from male BB chickens of the Cobb commercial line, fed for approximately 27 days with 3 isoprotein and isoenergetic diets based on: corn and soy; soybeans plus flax oil and soybeans plus fish oil. The hamburgers, made with a mixture of fresh skinless chicken breast and thigh meat, oat bran and a commercial mix of spices, were vacuum-packed and cooked at 80 °C for 10 min. Chemical analyses (moisture, fat, protein, fiber, thiobarbituric acid and fatty acid profile), color and texture profile were performed. The samples enriched with fish oil presented significantly higher values of docosapentaenoic acid (1.53 g of fatty acid per 100 g of fat) than the control sample (0.30 g of fatty acid per 100 g of fat). The sensory characterization was carried out by 54 consumers using the CATA methodology (check all that apply). The chicken-meat hamburger enriched with fish-ω3 oil was the most widely accepted by consumers. Therefore, a functional food product enriched with ω3 polyunsaturated acid close to the daily recommendation (250 mg) was designed. The sensory acceptability of consumers was found based on a pleasant taste, pleasant appearance and chicken flavor.
