Abstract

Edible oil adulteration poses a significant threat to public health and erodes consumer trust in the food industry. This study presents an innovative approach to detect edible oil adulteration by leveraging the capabilities of Fiber Bragg Grating (FBG) sensors, known for their speed and accuracy. The FBG based sensors were employed to monitor the refractive index (RI) of edible oils (pure coconut oil), enabling the identification of adulterants introduced during the adulteration process with a lower-quality oils such as paraffin oil. Rigorous experiments were conducted to assess the reduced graphene oxide (rGO) coated FBG sensor’s efficacy in detecting adulteration. The remarkable sensitivity and specificity of the rGO-coated eFBG sensor were demonstrated through its ability to detect and measure even minute changes in RI induced by the presence of adulterants. Utilizing rGO-coated eFBG sensors yielded a sensitivity of 26.62 nm/RIU. Indicating the potential of FBG sensors to improve food safety and quality control regulations, the results exhibit the capability of these sensors to detect paraffin-adulterated coconut oil.
