The detection of sugar in honey by transmission fiber optic displacement sensor

A fiber optic displacement sensor (FODS) using a transmission technique was developed to determine the purity of honey. This was achieved by detecting the output signal of pure honey and adulterated honey with different addition percentage volume of sugar (fructose and glucose). Five types of honey...

This was achieved by detecting the output signal of pure honey and adulterated honey with different addition percentage volume of sugar (fructose and glucose).

The displacement was verified within the range of 0 mm to 5.0 mm and 0 mm displacement was found to be the optimized distance for this beam through technique. The output voltage was found to be inversely proportional to displacement. The sensitivity was found to be 32.65 mV/mm with a correlation coefficient of 99%. The result from performance of sensor towards pure and adulterated honey showed that the highest sensitivity of all samples was achieved at 10% concentration of adulteration and the lowest sensitivity was obtained at 0% adulteration (pure honey). The highest sensitivity with adulteration was found in honey E with a sensitivity of 3.17 mV/% for fructose and 4.94 mV/% for glucose.
