Ecosistemas y recur. agropecuarios [online]. 2019, vol.6, n.16, pp.103-114.  Epub 01-Out-2019. ISSN 2007-901X.  https://doi.org/10.19136/era.a6n16.1894.

Lake Titicaca’s outstanding biodiversity includes birdlife, which not only fulfills important ecological roles, but is also used in human nutrition; however, its nutritional and organoleptic characteristics are unknown. Therefore, the objective of this study was to determine the proximal composition of the meat of the puna teal duck (Spatula puna), Andean coot (Fulica ardesiaca), common moorhen (Gallinula chloropus), ruddy duck (Oxyura jamaicensis) and Titicaca grebe (Rollandia microptera), and their possibilities of sensorial acceptance by people not accustomed to their consumption. Moisture content, protein, fat, ash, carbohydrates and energy were determined, considering six replicates per species. Sensory evaluations of raw meat were also conducted through a panel of 24 judges who determined its acceptability. All the meats have moisture between 71 and 76% and protein between 18 and 22%, with differences among species, highlighted by the Andean coot with 22.38%. The fat concentration differed among species, with the common moorhen having the highest content with 5.9%. Ash ranged between 0.8 and 1%, carbohydrate contents did not exceed 1% and the common moorhen had the highest energy level with 142.98 kcal 100 g−1. The highest energy amount was related to the highest fat levels (r = 0.83) and the moisture content with lower protein contents (r = -0.82); the highest protein content occurred in the dry season and the highest fat content in the rainy season. Organoleptically, the meats were not accepted by the panel, cataloging them as only fair.
