    Desarrollo de un Manual de Buenas Prácticas de Manufactura para la microempresa H-Vida, ubicada en la parroquia Pilaló del cantón Pujilí

    This study focuses on a Good Manufacturing Practices Manual for the microenterprise H-Vida, located in the Pilaló parish of the Pujilí canton. The purpose is to prepare facilities and process conditions so that in the future, they can obtain certification by ARCSA, with the objective of generating high-quality and safe products for consumers. Subsequently, a diagnosis of the current state of the microenterprise was carried out using a verification guide consisting of 211 items and three levels of scale: comply with the total requirements, Does Not Comply for conditions that are not under the standards of the Standard, and Not Applicable, when the requirements do not fit the establishment's activities due to the nature of the process and food. The results revealed 31 percent compliance, 52 percent non-compliance, and 17 percent of items not applicable. Standard operating and sanitation procedures were then developed based on the nonconformities and requirements identified in the microenterprise, in accordance with Resolution ARCSA-DE-2022-016-AKRG. Finally, an action plan has been drawn up that includes necessary corrective measures is adjusted to the suggested short-term budget. The main objective of this plan is to propose the necessary corrections to the nonconformities identified in the establishment so that the microenterprise can obtain good manufacturing practice certification from the regulatory agency, ARCSA, in the future.

    Caracterización de bacterias y testeo de métodos de desinfección de botellones de agua de la planta Fuente San Felipe S.A. ubicada en el cantón Latacunga provincia de Cotopaxi
    (Universidad Técnica de Ambato. Facultad de Ciencia e Ingeniería en Alimentos y Biotecnología. Carrera de Ingeniería en Alimentos, 2022-09) Bonilla Vizuete, Jeniffer Stefania; Pérez Salinas, Ruth Narcisa
    The problem of bottled water quality is acute throughout the world, and it has been addressed with water testing that ensures accurate and timely results. Bottled water manufacturers are tasked with testing larger volumes of samples, even dealing with unexpected emergencies, while adhering to more stringent local regulations. The use of returnable bottles has determined that there are contaminants due to improper handling of the containers, exposure to the environment and wear of the bottle materials. This study focused on establishing the microbial load, identifying the microorganisms involved and proposing continuous improvement protocols to ensure the food safety of bottled water from the Fuente San Felipe S.A. plant. Evidence of bacterial contamination was found in the returnable bottles. The presence of aerobic mesophiles was determined, which are indicators of contamination due to exposure to the environment, total coliforms, without finding evidence of fecal contamination and the critical microorganism found to establish the quality of water was Pseudomonas stutzeri. The disinfection protocol was adjusted to eliminate this microorganism with the use of hydrogen peroxide in concentrations of up to 3 percent and applications of up to 15 minutes of contact in the bottles, the latter being considered the best treatment. In order to ensure the quality of the final product, a food quality and safety management system is proposed, based on measurement, analysis and improvement of the disinfection and packaging processes.

    Diseño de un Plan para mejorar la calidad del agua embotellada de la Empresa Municipal de Agua potable y Alcantarillado de Guaranda
    (Universidad Técnica de Ambaro. Facultad de Ciencia e Ingeniería en Alimentos. Maestría en Gestión de la Producción Agroindustrial, 2017-11) Solórzano Saltos, Edwin Álvaro; Córdova Suárez, Manolo Alexander
    The research was developed in the Municipal Water and Sewerage Company of Guaranda (EMAPAG), aimed at designing a plan to improve the quality of bottled water considering the requirements established in ISO 10005: 2005. The initial diagnosis identified a 22 % compliance with the requirements of the quality plan. Through a Pareto diagram an order of priorities was assigned to the identified problems within which the planning, production and processes related to the client stand out. A survey was applied to clients and workers of the company to know the perception they have about internal aspects linked to production, establishing that the company does not have protocols implemented for the development of the activities involved in the water bottling process, as well as communication and feedback with the client. The quality plan designed for the company specifies what procedures and resources should be applied, who should apply them and when they should be applied. At the end of the research phase, the requirements verification sheet of ISO 10005: 2005 was applied again, reaching 84% compliance, which demonstrates the applicability and efficiency of the plan.

    Desarrollo del proceso de desinfección para agua embotellada a base de Ozono (O3) en la Planta de Tratamiento de Agua Envasada de la Empresa Pública - Empresa Municipal de Agua Potable y Alcantarillado de Ambato (EP - EMAPA -A)
    (Universidad Técnica de Ambato. Facultad de Ciencia e Ingeniería en Alimentos. Carrera de Ingeniería Bioquímica, 2017-04) Gavilanes López, Jonathan Vinicio; Córdova Suárez, Manolo Alexander
    Ecuador is one of the latin american countries with high levels of consumption for bottle water. The Ecuadorian Technical Norm NTE INEN 2 200:2008 establishes the physicochemical and microbiological parameters requested for water to be bottled up, focusing mainly in safeguard the integrity of users who consume this generalized product worldwide. This investigation was done seeing the need of Empresa Publica- Empresa Municipal de Agua Potable y Alcantarillado de Ambato (EP-EMAPA-A), for implementing an efficient disinfection process for bottled water, for this reason Ozone (O3) was chosen between the most effective, considering it`s high microbicidal power, short contact times and minimum quantities of by- products formed. Considering these criteria, it was determined that the optimum dose of ozone in water to be bottled is 0,15 mgO3/L (Dosage Scale: 1,75 g/h), maintaining a residual ozone concentration equivalent to 0,08 mgO3/L and 0,07 mg/L as demand for ozone required to disinfect water. These established concentrations are supported by previous physicochemical, microbiological and sensorial analyzes carried out to verify the quality and guarantee of the water that will be provided to the local community as an additional service by EP-EMAPA-A.
