dc.descriptionIn the food industry, it is crucial to validate analytical methods for the testing of nutrients and components in processed food products, especially with the recent inclusion of warning labels. This paper introduces a novel methodology for determining sodium levels in fried corn-based snacks. The main objective of this study was to determine the reliability of the method in consistently delivering accurate results. The methodology involved a thorough validation of the flame photometry analytical method to precisely measure the sodium content in corn-based snack foods. The equipment results were linearized for the specific analyte, and its accuracy was determined by calibration curves at four control points using two sodium standards. One standard was standardized control, and the second was prepared by directly diluting the food matrix of interest. The limits of the equipment for sodium detection and quantification were determined. Accuracy was evaluated using experimental recovery percentages. The results of the method’s standardization were evaluated for 10 months by analyzing 150 corn-based snack samples and obtaining measurement data from stable sodium tests compared to the data reported on the packaging. The results indicated the accuracy and linearity of the method through a linear regression curve and analysis of variance, as well as homogeneity and homoscedasticity by applying the t-statistic and the Cochran Q test. Finally, the conclusion is that the method provides fast, safe, reliable, and accurate results. The sample analyzed is in compliance with the regulations for low-sodium foods without a warning label.en-US
dc.descriptionEn la industria alimentaria es crucial validar los métodos analíticos para el análisis de nutrientes y componentes en productos alimenticios procesados, especialmente, con la reciente inclusión del sistema de etiquetado frontal de alimentos. En este artículo se presenta una metodología novedosa para determinar los niveles de sodio en pasabocas fritos a base de maíz. Esta investigación tuvo como objetivo determinar la fiabilidad del método a la hora de proporcionar resultados precisos de forma consistente. La metodología consistió en una validación exhaustiva del método analítico de fotometría de llama para medir con precisión el contenido de sodio en pasabocas a base de maíz. Los resultados del equipo se linealizaron para el analito específico, y su precisión se determinó mediante curvas de calibración en cuatro puntos de control utilizando dos estándares de sodio. Un estándar era un control normalizado, y el segundo se preparó diluyendo directamente la matriz alimentaria de interés. Se determinaron los límites del equipo para la detección y cuantificación de sodio. La precisión se evaluó utilizando porcentajes experimentales de recuperación. Los resultados de la normalización del método se evaluaron durante 10 meses analizando 150 muestras de aperitivos a base de maíz y obteniendo datos de medición de las pruebas de sodio estable comparados con los datos indicados en el envase. Los resultados indicaron la precisión y linealidad del método mediante una curva de regresión lineal y un análisis de varianza, así como la homogeneidad y homocedasticidad aplicando el estadístico t y la prueba Q de Cochran. Finalmente, se concluye que el método proporciona resultados rápidos, seguros, fiables y precisos. Adicionalmente, se encontró que la muestra analizada cumple la normativa sobre alimentos bajos en sodio sin etiqueta de advertencia.es-ES
