Abstract

Lard adulteration in edible oil products gives the concern to develop a method for the detection of lard substance in oil products. In this paper, a tapered plastic optical fiber (POF) was investigated experimentally to detect lard in olive oil. Tapered POF is a sturcture made by reducing the fiber diameter gradually. Taper length and taper waist diameter were varied to evaluate the performance of the tapered POF for detection of lard adulteration in olive oil. A maximum sensitivity of 0.858 dBm/%(v/v) was obtained by using tapered POF with a taper length of 1 cm and taper waist diameter of 0.45 mm.
