04/06/2014  Food Safety Effects of Pulsed Light When a food material is exposed to pulsed light, the energy can be absorbed, reflected or transmitted (Figure 2). The intensity of pulsed light exponentially decays within the food matrix. When light, with an initial intensity of Io, penetrates the food, its intensity decays along a distance x beneath the food surface. The actual intensity (I) available at ...
