TWO DIMENSIONAL PHOTOLUMINESCENCE IMAGING OF FOOD FOR NON-DESTRUCTIVE QUALITY CONTROL

• Abstract:

  Non-destructive evaluation technique of the foods including starches has been developed based on photoluminescence from starches in the foods. The visible PL with broad peak at wavelength of λ = 462 nm are observed from various foods including starches, such as polished rice, flour and corn starch, under illumination of ultra-violet (UV) light at λ = 365 nm. Peak intensity is found to vary with the source and the breed of the specimens. PL images from starches also reveal the uniformity of the food products. Two-dimensional images of PL, which revealed the uniformity of foods under UV irradiation, are potentially useful for the evaluation and the quality control of the foods and starchy products.
