Light irradiance within dry sausages was studied. Monochromatic light provided by lasers was transmitted into and out of the sample through optical fibers. The light irradiance was detected as a function of the distance between the excitation point at the end of the source fiber and the end of the detector fiber. The mean penetration depths within dry sausages decreased at 457 nm from 1.7 to 0.6 mm, and at 625 nm from 2.8 to 2.1 mm from production day to finished product (28 days later). Use of fiber optics in combination with lasers represents a possible method for continuous spectral measurements within food products.
