El presente trabajo de investigación tiene como objetivo diseñar y construir un biorreactor batch tipo tanque agitado y aireado con capacidad de un litro para la producción de proteína unicelular. Para su diseño y construcción se empleó un software que genera las especificaciones ideales para este tipo de trabajo, materiales y accesorios fácilmente manipulables y esterilizables a base de vidrio, tapones de caucho para uso químico y mangueras de plástico, el sistema de agitación se construyó con materiales de acero inoxidable más la adición de un motor de paso de 12 V. El biorreactor construido garantiza la esterilidad del sistema, una buena transferencia de oxígeno, calor y masa, al mismo tiempo que genera un mezclado uniforme tanto de la suspensión celular como del caldo fermentativo. Este tipo de biorreactor se diseñó con el propósito de generar las condiciones ideal...

factor involved in controlled muscle of shrimp drying permits process optimisation and assists in design of suitable dryers. The study undertook two stages: first a thermal pre-treatment submerging the whole shrimp in water at 90ºC for 90 seconds, were the orange colour and textura was improved. Was used then the sample underwent osmotic dehydration in ternary solution of 20% suerosa and 20%of NaCI ( % weight) under agitation at 120 rpm for 30 minutes to temperatura of 20ºC. The second stage was the drying where the experimental curves were obtained in laboratory dryer under different drying conditions from 40, 50 and 60ºC , and air velocity from 0.5, 0.8 and 1.1 m/s. during this whole process the time of drying was controlled at regular time in someway, the loss weight produced by the evaporation of water contained in the muscle was controlled. With this parameter the product was obt...

Ullucus tuberosus is an Andean region crop adapted to high-altitude environments and dryland cultivation. It is an essential resource that guarantees food security due to its carbohydrate, protein, and low-fat content. However, current change patterns in precipitation and temperatures warn of complex scenarios where climate change will affect this crop. Therefore, predicting these effects through simulation is a valuable tool for evaluating this crop’s sustainability. This study aims to evaluate ulluco’s crop yield under dryland conditions at 3914 m.a.s.l. considering climate change scenarios from 2024 to 2100 by using the AquaCrop model. Simulations were carried out using current meteorological data, crop agronomic information, and simulations for SSP1-2.6, SSP3-7.0, and SSP5-8.5 of CMIP 6. The results indicate that minimum temperature increases and seasonal precipitation exacerbati...
