The objective of this study was to evaluate the elaboration of a salami that contains a natural colorant extracted from the seeds of ayrampo (Opuntia soehrensii), using an extract of this natural product at different concentration levels and using microbiological and sensorial characteristics as acceptance criteria of the final product. Initially, a physicochemical characterization of the seeds was carried out, which showed the high nutritional value of this natural product and its antioxidant power. In an experiment aimed at determining the effect of the concentration of the ayrampo seed extract on the quality of salami, it was shown that for extract concentrations between 150 and 250 g / L of water in the meat mass, there are no significant differences in terms of the characteristics of smell, color, taste and appearance of the final product. This was sensory tested through a 9-point h...

In the present investigation it will benefit the rural population of the High Andean communities, that adopt biogas and biofertilizer as alternative energy and organic fertilizer, respectively; As they will have at their disposal an ecological fuel and organic fertilizer throughout the year, improving their quality of life.For this purpose, tubular biodigesters of PVC geomembrane of 8 and 12 m3 of total volume (1.27 m in diameter and 6.7 to 10 m in length) were used, with 6 and 9 m3 of working volume, respectively, occupied By the manure mixture of cattle: water in the proportion 1: 5. Biodigesters were installed in the Andean communities.Ancash. Peru. Based on the results obtained, at 38 days of loading the biodigester, the biogas produced reached a pressure of 10 cm of water throughout the system. For all this activity, it was required an operating time of the kitchen to biogas of two ...

Based on the need to make accurate decisions in the face of the COVID-19 pandemic in Peru, pandemic in Peru, specifically for the recovery of the tourism sector. For this purpose, a characterization of the behavior of the pandemic was carried out in the first three months of its development, based on the analysis of trends and the determination of the effective reproduction number (Rt) from statistical-mathematical methods. A variant of the SIR mathematical model was applied to forecast the possible evolution of the pandemic. This model was adjusted with the GlobalSearch optimization strategy of the MATLAB software. His solution used the MATLAB function ode23tb, which uses a combined Runge-Kutta algorithm with a trapezoidal rule algorithm. With the application of the Kaizen strategy as a means of continuous improvement, a set of actions were proposed that could be carried out today and t...
