Abstract
En los supermercados se pueden encontrar una amplia gama de bebidas, incluyendo las bebidas frutales. Hay diversas clases de bebidas sin alcohol, que se distinguen por su composición y sólidos solubles. El objetivo de este estudio fue determinar propiedades fisicoquímicas y etiquetado nutricional de las marcas comerciales Gloria, Pulp, Watts y Frugos del valle. Este estudio se dividió en dos partes, en la primera se realizó el análisis fisicoquímico de las muestras. En la siguiente parte fue un análisis descriptivo del etiquetado nutricional de las mismas. Mediante este análisis se encontró que las muestras de Gloria y Pulp presentaron los mejores valores respecto a los nutrientes críticos (Los Azúcares Totales, sodio y grasas saturadas), vitaminas, fibra dietética y proteína. Analizando los aditivos alimentarios resaltaremos que estas marcas declaran en su composición que los estabilizantes y colorantes de toxicidad baja; con respecto a los edulcorantes poseen una toxicidad media en comparación con las otras muestras. Las muestras analizadas no cumplen con los requisitos exigidos por la Norma técnica peruana (NTP Nº203.110:2009) en cuanto a sólidos solubles, pH y acidez. En el caso de Pulp cumple con el pH. Por otro lado, los sólidos solubles de 4.767 y el % de acidez de 0.168% no cumplen con la norma. Se analizó también otros parámetros como los sólidos totales 4.789; la densidad 1.015g/cm3; azúcares reductores de 15.687(g/L); los parámetros de color fueron: a es 9.337; b es 61.687 y L desde 65.173. De acuerdo con el análisis de varianza (ANOVA) existen diferencias altamente significativas entre las marcas. Se complementó con una prueba de Tukey de comparación múltiple de medias a los resultados de las mediciones.
ABSTRACT Supermarkets offer a wide variety of beverages, including fruit-based drinks. There are different types of non-alcoholic beverages, distinguished by their composition and soluble solids. The objective of this study was to determine the physicochemical properties and nutritional labeling of the commercial brands Gloria, Pulp, Watts, and Frugos del Valle. The study was divided into two parts. In the first part, the physicochemical analysis of the samples was conducted. The second part consisted of a descriptive analysis of their nutritional labeling. Through this analysis, it was found that the Gloria and Pulp samples exhibited the best values in terms of critical nutrients (total sugars, sodium, and saturated fats), vitamins, dietary fiber, and protein. Regarding food additives, these brands declared the use of stabilizers and colorants with low toxicity; however, their sweeteners showed medium toxicity compared to the other samples. The analyzed samples did not meet the requirements of the Peruvian Technical Standard (NTP Nº203.110:2009) concerning soluble solids, pH, and acidity. In the case of Pulp, the pH value complied with the standard. However, the soluble solids of 4.767 and the acidity percentage of 0.168% did not comply with the regulations. Other parameters were also analyzed, such as total solids (4.789), density (1.015 g/cm³), reducing sugars (15.687 g/L), and color parameters: a (9.337), b (61.687), and L (65.173). According to the analysis of variance (ANOVA), there are highly significant differences between the brands. This was complemented by a Tukey multiple comparison test on the measurement results.
