Trout was introduced in our country in 1928 and managed to adapt to the freshwater ecosystems of the Peruvian highlands. It currently represents the economic livelihood of many micro and small-scale fish farmers, together with medium and large companies in regions such as Puno, Pasco, Huancavelica and Junín, whose growth in recent years has been considerable. The 71.98% of this resource was destined for consumption in its fresh state and only 28.02% was processed as frozen, which shows the lack of diversification of value-added products in the production chain of this sweet aquaculture species, together with a shortage of research. Therefore, the purpose of this research was to compile the latest studies, carried out in different countries, related to the processing of this species because it is an excellent raw material due to its nutritional value and techno-functional characteristics...

El aumento de la producción de trucha en Perú genera gran cantidad de subproductos que generalmente no se reciclan, lo que causa gases de efecto invernadero, eutrofización cuando se arrojan al río, y aparición de plagas cuando se entierran.  Los procesos de hidrólisis y fermentación láctica permiten recuperar aminoácidos y nutrientes, los cuales pueden ser empleados como suplemento para la fertilización foliar de plantas. El objetivo de la investigación fue elaborar un fertilizante líquido utilizando subproductos de trucha (FLVT), caracterizarlo y evaluar la fitotoxicidad. El contenido total de aminoácidos fue de 3.2 g/100 g y el de proteína fue de 6.2 g/100 g; mientras el contenido de nitrógeno, fósforo y potasio fue de 12 040 mg/l, 1 189 mg/l, 5 540 mg/l, respectivamente. El fertilizante líquido no presentó E. coli ni Salmonella sp. Los contenidos de plomo, cadmio ...
