This article presents the microwave detection and analysis of honey adulteration. A study of the differences between pure and adulterated honey based on dielectric properties in the frequency range of 2 to 12 GHz was performed. A honey adulteration determination system using a free-space method with microwaves was developed. The transmitting section was responsible for generating a 2.4 GHz frequency signal using a high-frequency signal generator and radiating the signal power through a prototype transmitting antenna that propagated through the honey sample to the receiving antenna. All 72 honey samples were tested and categorized into six levels of adulteration. The average transmission power (S21) for pure honey and adulteration levels of 10%, 20%, and 50% was found to be 2.356, 2.321, 2.297, and 2.222 mV, respectively, with a coefficient of determination R2 of 0.969. The sensitivity of the detection was 0.027 mV/10% adulteration. The decision-making system was used to test the measurement of 144 honey samples. The sensor system achieved an accuracy of 95.83%, indicating that the non-contact microwave-based method for detecting honey adulteration is effective. [ABSTRACT FROM AUTHOR] |
