Spectrophotometric method for the quantitative determination of riboflavin content in cereal products
Year: 2026
Type: article
Abstract: This article explores and tests a spectrophotometric method for determining vitamin B2 (riboflavin) in processed cereal grains, with an emphasis on optimizing sample preparation and spectral analysis stages. Optical density measurements were taken, and a calibration curve was constructed using five standard riboflavin on a spectrophotometer at a wavelength of λ= 266 nm. Three cereal grain solutions were prepared, their ultraviolet absorption spectra recorded, and the riboflavin content in the analyzed samples determined. The established spectrophotometric method is simple, economical, the accuracy and free from the use of toxic solvents. Therefore, the aim of this study is to determine the vitamin B2 content in processed products and demonstrate its bioavailability.
