Riboflavin (Vitamin B2) is a key component for maintaining animal and human health. It is found in foods such as milk, cheese, mushrooms, almonds, and tomatoes. Riboflavin is also found in many energy drinks. The amount of riboflavin in a sample can be determined by fluorescence, which is the emission of photons as the molecule transitions from the excited singlet state to the ground state. For our research, solid-matrix fluorescence (SMF) will be utilized with glucose glasses as the matrix to determine the concentration of riboflavin in samples using an Ocean Optics Jaz Combo Spectrometer. Analytical figures of merit will also be determined and compared to riboflavin samples in a solution. Sugar glasses hold samples rigidly and their use for SMF has been previously shown to provide higher luminescence intensities and lower limits of detection than samples in solution.
