Fluorescent characteristics of bee honey constituents: A brief review.

The eligible articles were obtained from databases such as ScienceDirect, SciELO, PubMed and Springer. The searches were performed using the terms "honey", "vitamins", "fluorescence" and their combinations. The titles and abstracts of the articles found were read and revised to verify their relevance to the review. From the selected titles, it was possible to elaborate the systematic review, based on scientific studies and sources considered faithful and true. The systematic review presented confirms the necessity for studies to identify compounds using fluorescence techniques, using cheaper and more accessible techniques. Few studies are covered in this theme, when treated about Apis mellifera honey, and it has been observed that in the last 12 years, the few researches have only tried to show the viability of using the technique without quantifying the present compounds, while others demonstrate the fluorescent aspects, but performing through techniques considered more expensive.

Spectrofluorimetric analyzes of thiamine and riboflavin in monofloral honey varieties of africanized bees (Apis mellifera).

This research aimed to study the validation of a viable and low-cost spectrofluorimetric method, capable of detecting and quantifying B vitamins in floral varieties of bee honey. The analyzes were performed using chemical and operational methods of pre-defined solutions and standards, performed in triplicate and the results expressed as mean ± standard deviation. The data were recorded in a Microsoft Office Excel spreadsheet (version 2013) and studied using the statistical program Bioestatic version 3.0. The calibration curves of the vitamins showed the linearity and precision of the method. Subsequently, a descriptive analysis of the data was performed, being considered normal in the Lilliefors normality tests. Finally, the data were subjected to Pearson's correlation test, showing positive and strong correlations, with r (Pearson) ranging from 0.7619 to 1. Honey had positive results regarding the detection and quantification of vitamins B1 and B2 through the spectrofluorimetric method.
