dc.descriptionThe proposed study focused on the research and development of a mayonnaise-type sauce with different dosages of collagen extracted from tuna (Thunnus) waste, such as skin and scales, as an emulsifying alternative. With a latent problem, it is estimated that the waste of tuna conditioning is between 50% and 70% of the initial weight of the fish is discarded during this preparation process. The methodology implemented was a completely randomized experimental design consisting of 4 treatments, T1 without collagen, T3 with 4%, T3 with 8% and T4 with 8%. T3 with 8% and T4 with 12%. The inclusion of collagen increased the yield, viscosity, texture and consistency of the mayonnaise with a yield of 296 g (T2), 334 g (T3) and 369 g (T4) compared to T1, without collagen, of 288 g; the emulsifying power even increases with the inclusion of collagen, with T3 as the most efficient sample with 55.77 %; T1, T3 and T4 comply with INEN standards 389 and 381 referring to pH and acidity, and T2 does not comply with these standards. T2 was the most acceptable, followed by T1 and T3, while T4 was the least acceptable, which shows that the addition of collagen in moderate amounts improves its acceptability, but in high amounts it decreases it. It is recommended to carry out studies with different fish residues since they are a potential source of collagen.es_ES

dc.description.abstractEl estudio propuesto se centró en la investigación y desarrollo de una salsa tipo mayonesa con diferentes dosificaciones de colágeno extraído de residuos de Atún (Thunnus), como la piel y escamas como una alternativa emulsificante. Con una problemática latente la cual se estima que el desperdicio del acondicionamiento del atún esta entre el 50% y el 70% del peso inicial del pescado se desecha durante este proceso de preparación. La metodología que se implementó fue un diseño experimental completamente al azar constituido de 4 tratamientos, T1 sin colágeno, T3 con 4%. T3 con 8% y T4 con 12%. La inclusión de colágeno aumentó el rendimiento, la viscosidad, la textura y la consistencia de la mayonesa con un rendimiento de 296 g (T2), 334 g (T3) y 369 g (T4) en comparación con el T1, sin colágeno, de 288 g; el poder emulsificante incluso crece con la inclusión del colágeno, con T3 como muestra más eficiente con 55,77 %; T1, T3 y T4 cumplen con las normas INEN 389 y 381 referentes a pH y acidez, y T2 no cumple estas normas. El T2 fue el que presentó mayor aceptación, seguido del T1 y el T3, mientras que el T4 fue el que presentó menor aceptación, lo que demuestra que la adición de colágeno en cantidades moderadas mejora su aceptación, pero en cantidades elevadas la disminuyen. Se recomienda realizar estudios con diferentes residuos de pescado ya que son una potencial fuente de colágeno.es_ES
