A Feasibility Study on Monitoring Shelf Life of Bottled Natural Fruit Juice Using Laser-Induced Autofluorescence

Figure 1

Schematic diagram of laser-induced autofluorescence (LIAF) setup used for data acquisition. Light via one arm of the bifurcated fibre probe excites the sample from which the emitted light is collected through the other arm of the probe. A high-pass filter allows only fluorescence light into the spectrometer to be visualized and saved on the computer.
