The growing demand for healthy snacks necessitates accurate methods for lycopene analysis in tomato-based products. This study evaluated benchtop near infrared (N.I.R.) spectroscopy, portable NIR spectroscopy, and hyperspectral imaging (HSI) to quantify lycopene content in tomato snack bars, with chemical analysis as the standard chemical analysis method. According to the analysis, the benchtop NIR device achieved the highest accuracy (0.979), sensitivity (0.979), and specificity (0.990), making it the most reliable method. The portable device, while slightly less accurate (accuracy 0.861, sensitivity 0.861, specificity 0.931), offered rapid and cost-effective on-site analysis. HSI, with lower accuracy (0.708), provided valuable spatial information, revealing non-uniform lycopene distribution within the bars. In conclusion, combining NIR for fast quantification with HSI for spatial insights optimizes quality control, ensuring consistent lycopene content and nutritional value in tomato snack bars.
