本研究の主旨

Food quality and safety remains a concern today with several notable instances involving the agro-food industry. Thus, the food industry is still facing a permanent need for fast and noninvasive methods of food authenticity and quality evaluation. Spectroscopy based analysis has been widely used in the food industry to monitor food quality and safety. In this study Raman spectroscopy combined with imaging technique called Raman imaging technique was used for detection, identification and visualization of adulterant material in food products. Raman images of food products were acquired using a custom-designed laboratory based Raman imaging system. The Raman image of a single or multi-bands identical to the adulterant materials was preprocessed and used for detection of adulteration concentration in food products. The ultimate advantage of Raman imaging technique is that it does not require complicated statistical analytical methods to extract the relevant information from the acquired data of food products. In addition, this method is fast, accurate and nondestructive measurement, which can be a potential alternative to the conventional food inspection method. We believe that the purposed techniques could have a variety of applications in processing and evaluation of food products. The application of Raman imaging technique to examine products for foreign material and identify them could be another potential application in the food machinery industry.
