“…En Perú, la acuicultura y pesca representan un importante aporte al crecimiento del país, teniendo un crecimiento acelerado en la producción de diversas especies acuícolas. Esta actividad puede llegar a ser un rubro de producción económica muy importante a nivel país por las condiciones que ofrece el territorio nacional en cuanto a ambientes y la gran extensión de los espejos de agua propicios para esta actividad (SANIPES, 2020), un ejemplo son las regiones montañosas, como la cordillera de los Andes, que proporcionan recursos de agua dulce y dan origen a cultivos alimentarios en beneficio para los pobladores de las zonas altoandinas (Escobar et al, 2020).…”

The fishing industry generates large quantities of by-products, most of which are not used and are therefore discarded. The objective of the present research was the elaboration of a pâté-type sausage from mechanically recovered meat of rainbow trout (Oncorhynchus mykiss). The meat was obtained from trout skelons, which were passed through a grinder and sprayed with a mixture of α-tocopherol (0.02%) and ascorbic acid (0.05%). The formulation of the pate was as follows: mechanically recovered trout meat (74.4%), salt (1.3%), sodium tripolyphosphate (0.8%), starch (2%), soy protein isolate (2.4%), margarine (16.7%), soy lecithin (1.9%), onion powder (0.2%), garlic powder (0.2%) and pepper powder (0.1%). Three formulations were prepared: PCR1 (80% cooked meat and 20% raw meat), PCR2 (90% cooked meat and 10% raw meat) and PCR3 (100% cooked meat). For each formulation, the following were evaluated: texture profile, color and sensory evaluation, the latter with the participation of 30 untrained panelists using a 9-point hedonic scale, in which each formulation obtained an average of 6 ("I like it moderately"). The best formulation was PCR3, whose proximate composition was determined: 64% moisture, 16% fat, 12.5% protein, and 3.5% ash. The pâté of mechanically recovered trout meat proved to have a high nutritional value and a good level of sensory acceptance, demonstrating that it is a good alternative for the use of trout fillet by-products.

“…Los cambios ambientales que se han generado en las sabanas y zonas costaneras donde predominan las siembras de ñame pueden haber contribuido a la generación de variabilidad genética en estos hongos, por ende, se hace necesario que los agricultores de estas zonas puedan mitigar el impacto económico de los daños causados por estos patógenos en el cultivo de ñame . Una mejor comprensión de esta problemática en las sabanas y zonas costaneras de la región Caribe en Colombia podría contribuir a la recuperación de los niveles de ingresos de los pequeños productores y a un desarrollo más sostenible del cultivo de ñame (Escobar et al, 2020).…”

Capacidad de infección de hongos asociados a la pudrición seca de los Tubérculos de Ñame

et al. 2021

Dry rot of tubers is one of the most devastating diseases in yam production (Dioscorea rotundata Poir.) in the Caribbean region of Colombia. The disease attacks tubers, causing production losses during cultivation. In previous experiments, 11 fungal morphotypes were isolated and associated with this disease in yam crops in the Caribbean region of Colombia. The present investigation was carried out under greenhouse conditions to determine the infection capacity of these 11 possible causative agents, in 150-day-old plants of two yam genetic materials (0307-49SB y 0307-50CB). The results indicated that morphotypes DH2 (Lasiodiplodia theobromae), DH11 (Curvularia aeria), DH20 (Aspergillus niger), and DH17 (Fusarium equiseti), showed the highest infection capacity to yam tubers, regardless of the genetic material. Therefore, they were considered as the main causal agents of the disease in the Caribbean region of Colombia. The remaining seven (7) morphotypes, despite having been inoculated in the roots of the plants, showed minor effects on tubers and affected other organs of the plant, especially stems and aerial part of yam plant. This study allows concentrating the research on these four morphotypes to develop crop management strategies that might allow reducing the incidence of this disease in the Caribbean region of Colombia.
