## 5 Conclusions  
This paper presents an experimental investigation of a proposed fiber optic sensor using an SMS configuration to detect adulteration in honey by the two most common mechanisms: by the addition of glucose and moisture content. The sensor demonstrated its efficacy in detecting glucose adulteration at concentrations between 1% and 5% and in detecting moisture content ranging from 0% to 20% using distilled water. Rigorous testing involved two commercially approved honey brands complying with Mexican authenticity laws. The sensor exhibits notable advantages, including simple fabrication, the use of inexpensive conventional fibers, and a linear response, making it promising for quality assessment in the food industry. The results demonstrated the sensor's sensitivity, with values around \(-\)0.55457 nm/% for honey brand A and \(-\)2.61257 nm/% for honey brand B when detecting glucose adulteration and \(-\)0.3154 nm/% and \(-\)0.3394 nm/% when detecting moisture adulteration for honey brand A and B. The accuracy and reliability of the sensor were validated by comparing its measurements with those obtained from a conventional refractometer, showing close agreement and an absence of bias. The MMI device ensures effective performance when used at temperatures up to 30 \({}^{\circ}\)C, crucial for maintaining measurement accuracy under normal honey processing and storage \begin{table}

conditions. This feature significantly increases interest in the food industry as a robust mechanism for effectively monitoring honey adulteration levels, thus safeguarding honey product authenticity and quality in the market. The proposed MMI sensor offers several advantages over traditional refracometers. While refracometers are well-known for their high numerical sensitivity, this can make them more susceptible to environmental noise and fluctuations, potentially complicating measurements in real-world conditions. In contrast, the SMS sensor's lower sensitivity contributes to its superior stability and robustness in practical applications, allowing for more reliable and continuous real-time monitoring without frequent recalibration or complex maintenance. This is particularly beneficial in industrial settings where uninterrupted monitoring is critical to ensure product quality and consistency. Additionally, the SMS sensor's design facilitates integration into automated systems, reducing operational costs over time. Moreover, the MMI sensor allows continuous and real-time monitoring, enhancing its practicality for ongoing honey quality control in contrast with commercial refracometers that provide only discrete measurements. The MMI sensors have a simple structure using conventional optical fibers, making it a more cost-effective and accessible option. Its ability to detect small levels of honey adulteration with high sensitivity further positions the MMI sensor as an attractive alternative for ensuring honey quality. Also, the MMI sensor has other significant advantages such as sensitivity to multiple parameters, lower maintenance requirements, ease of integration into automated systems, portability, versatility in applications, and faster response times. These attributes make the MMI sensor a robust and flexible tool suitable for several industrial applications. Despite the inherent complexity of honey, which typically exhibits Newtonian behavior but can display non-Newtonian characteristics when adulterated, the sensor optimally addressed the challenge of measuring adulterated honey. This highlights the sensor's capability to account for the intricate rheological and optical properties of honey.
