Resumen
In this study, we introduce an approach for quickly profiling the nutritional content of fruit juices by using a portable Fourier transform mid-infrared (FT-IR) device. This method enables real-time prediction and simultaneous analysis of key components, such as sugars and acids in fruit juices, addressing concerns about obesity and other health risks. The portability of the FT-IR sensor makes it a valuable tool for food processors, providing a convenient out-of-the-laboratory solution. This application detects deviations in sugar and ascorbic acid levels compared to nutritional labels, helping consumers to make healthier decisions. Furthermore, applying portable FT-IR devices by the fruit juice industry will streamline quality control processes and represents a shift towards more efficient, non-destructive, and high-throughput analytical methods.
