The goal of this work has been to design and develop products such as fresh cheese and yogurt, enriched with polyunsaturated fatty acids. Fresh milk was used as raw material and soybean oil as source of polyunsaturated fatty acids. The content of polyunsaturated fatty acids in fresh cheese made from skim milk enriched with 2 to 4% soybean oil, increased from 5.01% to 54.83%. Similarly, the content of polyunsaturated fatty acids in natural yogurt made from skim milk enriched with 1 to 3% soybean oil, increased from 4.28% to 54.98%. We conclude that is feasible to produce dairy products enriched with polyunsaturated fatty acids and their manufacture is recommended.

This study aimed to evaluate the effect of five cooking methods (steam, grill, oven, frying and microwave) on farm-raised rainbow trout's sensory acceptability, physicochemical characteristics, and nutritional value. A survey was conducted with 307 consumers to create a marinade made with salt, garlic, cumin and pepper. The fillets marinated in this mixture were cooked, and photographs were taken to determine their sensory profile using the Check All That Apply (CATA) method, as well as their appearance through both visual (n = 289) and virtual (n = 100) surveys. Similarity was found between the sensory attribute maps for frying, oven and grilling in both evaluation methods. Significant differences (p < 0.05) in proximal composition were observed between the cooking techniques studied because of their technological parameters. The methods with the best visual acceptability were frying...
