Fluorescence Pattern Analysis to Assist Food Safety

––Food Analysis Technology Driven by Fluorescence Fingerprints––

Highlight

Fluorescence fingerprint analysis uses the large quantity of information contained in fluorescence patterns generated by organic components in samples to identify quality or place of origin, or to detect harmful substances. It is a simple and low-cost method that is gaining attention for its food industry applications. The Fluorescence Spectrophotometer F-7100 made by Hitachi High-Tech Science incorporates several technologies that enable high-throughput fluorescence fingerprint measurement. It is designed to have a full range of specialized functions for fluorescence fingerprint measurement, such as a new automatic filter accessory device that simply and rapidly removes the effect of spectrometer-specific higherorder light. This article presents its features and some example applications.
