本研究の主旨

The spectroscopic techniques for food quality analysis are limited to the surface inspection, and highly affected by the superficial layer (skin or packaging material) of food samples. Because the packed food market is growing rapidly and getting consumers’ attention; therefore, the quality analysis of packaged food has become important for both the food industry and regulating organizations. This can only be achieved by developing technique which can see through the superficial layer (of packaging) and retrieve the signals from the food inside. Therefore, in this study, spatially offset Raman spectroscopy (SORS)-imaging system is introduced which is least or not-effected from the superficial or packaging layer thus can be retrieve signals from the packed food samples.
The present research aimed to develop a macro-scale SORS technique for quality analysis of packed food products or layered samples which can further be used as an imaging technique for visualization of chemical distribution, but at a particular depth. The developed technique overcome the limitations of conventional spectroscopic techniques which are not able to collect the signals of subsurface materials from the layered or packed samples. We envisaged that the developed techniques will have the potential to be used as an effective quality analysis method for packed food safety evaluation.
