| Summary: | Milk adulteration is a pervasive global issue, particularly in developing nations. In order to meet consumer demand, various adulterants such as water, urea, and melamine are often added to increase the quantity or alter the properties of milk. These foreign substances lead to unwanted ailments if taken above a permissible level. The traditional approaches for detecting and analyzing adulterants often require sophisticated labs along with trained personnel. To address these impending issues, it is imperative that there should be a cost-effective rapid analytical scheme. Given these facts, this paper explores the feasibility of using U-shaped fiber optic sensors as an efficient and sensitive approach to detect milk adulteration. By leveraging the light propagation characteristics of fiber optics and the Localized Surface Plasmon Resonance (LSPR) phenomenon, this sensor can detect minor changes in the refractive index of milk caused by adulterants. Accordingly, this work delves into the working principle of U-shaped fiber optic sensors, design considerations, and the potential for scalable applications in milk quality assurance. |
