The extrusion process can be transferred to high Andean areas with the idea of generating value chains for the cultivation of Andean cereals and grains. An extruded product has been developed using cereals, Andean grains and pota protein concentrate (CPPo) to develop a nutritional bar that is well accepted by children from 5 to 10 years of age. The most acceptable product, qualified as a functional product, was made with 60.0% corn, 19.0% rice, 15.0% kiwicha and 6.0% CPPo, the main characteristic of which was the absence of pota odor and flavor. Subsequently, the nutritional bar was prepared using 57.5% of the extruded product and adding 27.5% sugar, 10.0% glucose and 5.0% grated coconut. In the proximal chemical composition of the nutritional bar, the content of proteins (9.56%), fats (3.10%), carbohydrates (79.49%), moisture (6.54%) and fiber (0.63%) are highlighted. The true digestibi...

El presente trabajo de investigación realizado en el músculo desmenuzado de pota tuvo por finalidad evaluar el proceso de hidrólisis con proteasa alcalina. Se utilizó ejemplares provenientes del puerto de Talara y se sometieron a un estudio comparativo entre el nivel de hidrólisis del músculo crudo y cocido. Se determinó que la utilización de la alcalasa 2.4 L para obtener hidrolizados proteicos en base a músculo de pota fue factible, obteniéndose como parámetros adecuados para el proceso: temperatura de 60 ºC, con un % (p/v) de 0,7 y pH de 6-8. Las características sensoriales del hidrolizado fue de un producto líquido de color blanco cremoso, no presentó olor ni sabor a pota y tampoco se detectó presencia de péptidos amargos. La composición química del hidrolizado fue: humedad 81,24 %, proteína total 15,98 %, ceniza 0,86 %, grasa 0,48 % y ELN 1,44 %. La proteína sol...

Se elaboró un producto preformado congelado “listo para el consumo” a partir de músculo desmenuzado de bonito (Sarda chiliensis) con inclusión de quinua (Quenopodium quinoa willd), con la finalidad de darle mayor valor agregado al recurso y asi promover su consumo. Para ello se elaboraron nueve formulaciones y una muestra control solo con pescado; las variables de estudio fueron polifosfato (0,1 %, 0,3 % y 0,5 %), quinua (3 %, 6 % y 9 %), mantequilla y aceite (2 %, 4 % y 6 %) respectivamente. Para la evaluación sensorial se analizaron las muestras a través de un panel de 15 jueces semi entrenados y para la determinación de los parámetros de textura se utilizó un texturómetro, Brookfield-Farnell QTS – 25. Los resultados de los estudios indicaron que el polifosfato al 0,5 %, quinua al 6 % y mantequilla 4 % mejoraron la textura en función de la jugosidad y sabor del producto...

This work aimed to produce cold-smoked skinless paiche fillets that comply with the quality, safety and acceptability standards regarding physical, chemical and microbiological aspects. The production stages were reception, washing, slicing and cutting, brining, draining, smoking, chilling, packaging, freezing and storage. The results showed that cold-smoked skinless paiche fillets had 75.10% moisture and 35.65% of 2.90% sodium chloride. The fillets had 20.0% protein, 2.5% fat and 2.4% ash. The total energy per 100 g of fish was 102.5 kcal. The microbiological results of the cold-smoked fillets met the recommended quality standards for this type of product, and confirmed that good manufacturing practices were used during their production.
