Due to its hygroscopicnature, bee pollen readily promotes microbial growth; however, there is no specific legislation for bee pollen inthe European Union. Microbiological contamination therefore stands out as a crucial factor in determining itsquality. To address this, the study focused on isolating bacterial and fungal colonies from bee pollen usingvarious culture media, followed by a protein extraction based on a lysis process. Identification was achievedthrough the Biotyper-MALDI-TOF (Matrix-Assisted Laser Desorption/Ionization coupled to Time-of-Flight de-tector) system. The greenness and blueness of the methods were assessed using different tools, which classifiedthem as environmentally friendly and practical. Thirty-two samples were analyzed using proposed sampletreatment approaches. Data were processed using chemometric techniques based on linear models. The resultsrevealed the presence of both beneficial and potentially pathogenic species, including key representatives such asBacillus licheniformis, Micrococcus luteus, and Aspergillus fumigatus. These findings highlight the importance ofmicrobiota characterization in bee pollen and demonstrate that MALDI-TOF is a rapid and effective tool forprofiling culturable microbial communities in this matrix.
