In recent years, ARS macro-scale Raman imaging techniques have demonstrated the value of Raman chemical imaging in detection of food adulterants. However, this system is limited to point-by-point Raman measurements that are too slow for use in a commercial food processing environments to evaluate a large volume of food materials. By joining resources, this cooperative research project will develop a commercial prototype line-scan-based Raman chemical imaging system for scanning a large sample surface in under 10 minutes. To enhance the sensitivity and specificity for detection of adulterants and authentication of food ingredients, sensing fusion for the above Raman and other imaging techniques, such NIR imaging, will be evaluated.
