Research Project: Development of a Real-Time in-Situ Evaluation Sensing System for Hazardous and Adulterated Food Materials

Location: Environmental Microbial and Food Safety Laboratory

Project Number: 1245-42000-018-29
Project Type: Trust

Start Date: Oct 01, 2013
End Date: Sep 30, 2016

Objective:
The objective of this cooperative research project is to develop and validate Raman imaging technologies for detection of hazardous food materials and to develop a rapid commercial prototype Raman imaging system suitable for in situ detection of hazardous food materials in commercial food processing environments. The common goal is to design and fabricate a commercial prototype hyperspectral Raman imaging system for detecting hazardous food materials in a commercial setting and to develop rapid image analysis methods for using hyperspectral Raman imaging technologies.

Approach:
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.
