Abstract

Consumption of natural orange juice is considered a healthy habit. Despite the wide offer of options such as fruit, vegetable or healthy smoothies to start the day, orange juice continues to be one of the favourite drinks to “start with energy”. Currently, a concern among general population, regarding nutritional importance and knowledge about how the foods consumed influence health is growing. Uruguay is the second largest exporter in Latin America and one of the twenty largest citrus exporters in the world, thus, analytical methods to monitor their nutritional value and quality are always being revised and modernized. This study focused on examining the correlation between different parameters assessed using standard methods and determined through near infrared spectroscopy (NIR) for Citrus sinensis Valencia orange juice. Besides, several parameters to characterize the nutritional value of this juice were determined and reported. The findings showed a novel correlation between NIR spectroscopy data and results obtained for calcium (Slope > 0.94 and Residual Predicted Deviation > 3) compared with standard methods which are discussed. Notably, the outcomes highlight NIR spectroscopy as a valuable approach for streamlining analyses, in this case calcium determination, significantly reducing the required resources-such as time and costs of parameters pivotal for assessing juice quality. The results indicate that the orange juice studied showed good nutritional quality parameters, besides calcium content can also be evaluated by NIR, being this technique in more agreement with the principles of Green Analytical Chemistry.
