ABSTRACT: This study optimized the rheological parameters of doughs with partial substitution of wheat flour for blends of whole grain flours from germinated Andean pseudocereals such as quinoa (GQF), kiwicha (GKF), and cañihua (GCF) for bread production. The optimization was conducted through a Simplex-Centroid Mixture Design (SCMD) and Desirability Function (DF). Experiments were formulated using 80 to 90% wheat flour and 5 to 15% germinated pseudocereal blends. The rheological evaluation included farinograph, extensograph, and amylography analyses. Results showed that whole flour from germinated pseudocereals increases the water absorption, consistency, and extensibility of the doughs; and decreases its development time, stability, resistance to extensibility, temperature, and peak viscosity. The GQF-GKF blend developed more extensible and stable doughs, while GCF increased its consistency and was recommended for bread production. The data allowed us to obtain response surface models and the optimal substitution percentages to produce bread using GQF-GKF, GQF-GCF, and GKF-GCF blends.

RESUMO: Este estudo teve como objetivo otimizar os parâmetros reológicos de massas com substituição parcial de farinha de trigo por blends de farinhas de grãos inteiros germinados de pseudocereais andinos como quinoa (GQF), kiwicha (GKF) e cañihua (GCF) para a produção de pães. A otimização foi realizada através de um Planejamento de Mistura Simplex-Centróide (SCMD) e a Função de Desejabilidade (DF). Os experimentos foram formulados com 80 a 90% da farinha de trigo e 5 a 15% de farinha de pseudocereais germinados. A avaliação reológica incluiu as análises de farinografia, extensografia e amilografia. Os resultados mostraram que a inclusão de farinhas germinadas aumenta a absorção de água, a consistência e a extensibilidade das massas; e diminui seu tempo de desenvolvimento, estabilidade, resistência à extensibilidade, temperatura de gelatinização e viscosidade pico. O blend GQF-GKF desenvolveu massas mais extensíveis e estáveis, enquanto a GCF aumentou sua consistência, por tanto foi recomendada a produção de pães. Os dados nos permitiram obter modelos de superfície de resposta assim como as porcentagens de substituição ótimas para produzir pães usando os blends de GQF-GKF, GQF-GCF e GKF-GCF.

ABSTRACT The study to implement an occupational safety and health system, based on Peruvian law No. 29783, to reduce the level of risk in a fishing company. The research design was pre-experimental, where the sample was made up of the risks of the production area. The initial diagnosis determined that the company was law-enforcement, below 60%; placing it in a state of legal disapproval. Were detected 29 risks that increased the probability of occurrence and severity of accidents. A health and safety system was designed that implemented administrative procedures and engineering controls. Finally, the post-test IPERC matrix ( Risk identification, evaluation and control) showed that the implementation of Peruvian law No. 29783 reduced the level of risk from an initial median of 18 to an average value of 6; inferential analysis also established that the difference was significant (α<0.05).

RESUMEN El estudio implementó un sistema de seguridad y salud en el trabajo, basado en la ley peruana Número 29783, para reducir el nivel de riesgo en una empresa pesquera. El diseño de investigación fue preexperimental, donde la muestra estuvo conformada por los riesgos del área de producción. El diagnóstico inicial determinó que la empresa presentaba un cumplimiento de la ley, por debajo del 60%; ubicándola en un estado de desaprobación legal. Se detectaron 29 riesgos que incrementaban la probabilidad de ocurrencia y gravedad de accidentes. Se diseñó un sistema de seguridad y salud que implementó procedimientos administrativos y controles de ingeniería. Finalmente, la matriz IPERC (Identificación de Peligros, Evaluación y Control de Riesgos) de post prueba demostró que la implementación de la ley peruana Número 29783, redujo el nivel de riesgo pasando de una mediana inicial de 18 a un valor medio de 6; asimismo, el análisis inferencial estableció que la diferencia era significativa (α<0.05).
