The kinetic of degradation betacyanins, betaxantins and vitamin C at 30 °C, 40 °C and 50 ºC was evaluated in a commercial beverage made of beet and honey, using the kinetic models of zero, first and second order; and Arrhenius model to evaluate the dependence of the rate of degradation with respect to temperature. It was determined that the degradation of the three compounds evaluated at the three tested temperatures followed a first order kinetics with a high correlation (R2 = 0.974, 0.98, 0.979). It was determined that the betacyanins and vitamin have a similar sensitivity to temperature; while betaxantins were more stable. Referring to the influence of temperature on the degradation rate, the activation energy and the reaction Q10 values were determined which confirm the increased stability of betaxantins regarding betacyanins and vitamin in the beverage of beet and honey.

Cuando se presume que el tiempo de vida útil de un alimento es largo, se han desarrollado técnicas de ensayos acelerados que acortan considerablemente el proceso de obtención de los datos experimentales necesarios para predecirlo. El objetivo de este trabajo fue determinar el tiempo de vida útil de la bebida a base de jugo de remolacha y miel de abeja elaborada por la empresa vida saludable del Perú E. l. R. L. Se malizaron estudios cinéticos y pruebas de vida útil aceleradas, almacenando unidades de muestreo a temperaturas controladas de 30, 40 y 50°C; durante el tiempo de almacenamiento se realizaron análisis fisicoquímicos (determinación de betacianinas y vitamina C) y sensoriales (color y sabor). La degradación de betacianinas y vitamina C siguieron una cinética de primer orden. Las energías de activación fueron 23,645 y 24,023 Kcal/mol para betacianinas y vitamina C r...

In 2021, signs indicating a low quality of the broadcasting authorization service provided by the Dirección de Servicios de Radiodifusión (DSR) in Peru were perceived. These signs indicate a deficient implementation of the la Política de Modernización de la Gestión Pública approved by Decreto Supremo N° 004-2013-PCM. Therefore, the objective proposed was to assess the implementation of the Política de Modernización de la Gestión Pública at DSR and to verify the relationship with the quality of the service provided. A quantitative research approach (deductive) was applied, with a non-experimental design, surveying a population of 104 administrators. Problems were evidenced in all the components of the implemented Política de Modernización de la Gestión Pública (management by processes, administrative simplification and organization), with a significant and direct relationsh...

The Covid 19 Pandemic changed the way teaching-learning is carried out, generating problematic effects on school students, especially in rural areas where education is characterized by precariousness and limited access to basic services necessary for compliance. of basic education. One of the problematic effects could be the presence of stress, so this work aimed to investigate the degree of academic stress, stressors, stress symptoms and coping strategies in students attending school in rural Peru. Valid and reliable surveys were applied to a population of 114 school students distributed into three groups according to age and gender. It was found that 32.5% and 33.3% of students presented a moderate and severe level of academic stress respectively, there are no statistical differences due to the variation in the age of the students, but there were differences by gender, with the female ...
