Fluorescence Pattern Analysis to Assist Food Safety —Food Analysis Technology Driven by Fluorescence Fingerprints—

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 ... Read more>

Introduction of food distinction technology by fluorescence fingerprint measurement with F-7000

Fluorescence fingerprinting for food distinction is a technique for multivariate analysis of numerical data entailing acquisition of a fluorescence pattern unique to a specimen (fluorescence fingerprint) and analysis of fluorescence intensity in the massive amount of data acquired. Anticipated applications include identification of samples and determination of their ... Read more>

Introduction to Key Features and New Capabilities of the F-7100 Fluorescence Spectrophotometer

A fluorescence spectrophotometer is an instrument that measures the fluorescence produced by a sample irradiated with optical excitation such as ultraviolet radiation. Fluorescence spectrophotometers are higher-sensitivity analytical instruments than absorption spectrophotometers, which measure light absorption by the sample. Because only fluorescent substances ...

Detection of Food Safety Using Fluorescence Fingerprint

Before describing fluorescence fingerprints, first we describe the known phenomenon of fluorescence. Typically, as shown in Fig. 1 (left) fluorescence refers to irradiation of a specimen with light comprising only a certain, specific wavelength component (an excitation wavelength), and in response, generation of light of various wavelengths (a fluorescence spectrum). In ... Read more>
