Diseño e implementación de una guía de estandarización para la medición de grados Brix mediante refractometría, como aporte al fortalecimiento del sistema de gestión de calidad en el laboratorio de Italcol Latinoamérica.

Abstract

The purpose of this project was to design and implement a standardized technical guide for measuring Brix degrees through digital refractometry in the quality laboratory of Italcol Latinoamérica. The study was motivated by the limitations identified in the traditional hydrometry method using a saccharimeter, which affected the reliability, traceability, and reproducibility of analytical results. A mixed-methods research approach was applied, combining documentary analysis, regulatory evaluation, direct process observation, technical comparison of measurement methods, and the development of management tools for process standardization. In addition, the requirements established by ISO 9001:2015 and ISO/IEC 17025:2017 were analyzed to ensure compliance with internationally recognized quality and technical competence standards. The results revealed operational, technical, and documentary deficiencies associated with the traditional method, while highlighting the advantages of digital refractometry in terms of speed, repeatability, reduction of human error, and metrological control. As a primary outcome, a standardized technical guide was developed, including operating procedures, acceptance criteria, recording formats, and control mechanisms that strengthen measurement reliability and result traceability. Furthermore, a change management and training plan was designed to support laboratory personnel during the transition process and promote the successful adoption of the new methodology. The study concludes that implementing the standardized technical guide significantly strengthens the quality management system of Italcol Latinoamérica by improving analytical consistency, metrological traceability, and compliance with applicable regulatory requirements.
