Multifloral and unifloral bee pollen samples collected from continental, mountain and Adriatic regions of Croatia were analyzed by means of physico-chemical, chromatographic (GC-MS), and spectroscopic (FTIR-ATR) analytical tools, aiming to conduct a comprehensive characterization of bee pollen. The most distinctive unifloral bee pollen with regard to nutritional value was Aesculus hippocastanum (27.26% of proteins), Quercus spp. (52.58% of total sugars), Taraxacumofficinale (19.04% of total lipids), and Prunusavium (3.81% of ash). No statistically significant differences between multifloral and unifloral bee pollen from different regions were found for most of the physico-chemical measurement data, with an exception of melezitose (p = 0.04). Remarkable differences were found among the bee pollen HS VOCs. The major ones were lower aliphatic compounds, monoterpenes (mainly linalool derivatives, especially in Prunusmahaleb and P.avium bee pollen), and benzene derivatives (mainly benzaldehyde in T.officinale and Salix spp.). Aldehydes C9 to C17 were present in almost all samples. FTIR-ATR analysis revealed unique spectral profiles of analyzed bee pollen exhibiting its overall chemical composition arising from molecular vibrations related to major macromolecules\u2014proteins, lipids, and carbohydrates (sugars).<\/jats:p>","DOI":"10.3390\/foods10092103","type":"journal-article","created":{"date-parts":[[2021,9,6]],"date-time":"2021-09-06T21:47:38Z","timestamp":1630964858000},"page":"2103","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":77,"title":["Characterization of Bee Pollen: Physico-Chemical Properties, Headspace Composition and FTIR Spectral Profiles"],"prefix":"10.3390","volume":"10","author":[{"given":"Sa\u0161a","family":"Pr\u0111un","sequence":"first","affiliation":[{"name":"Department of Fisheries, Apiculture, Wildlife Management and Special Zoology, Faculty of Agriculture, University of Zagreb, Sveto\u0161imunska cesta 25, 10000 Zagreb, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lidija","family":"Sve\u010dnjak","sequence":"additional","affiliation":[{"name":"Department of Fisheries, Apiculture, Wildlife Management and Special Zoology, Faculty of Agriculture, University of Zagreb, Sveto\u0161imunska cesta 25, 10000 Zagreb, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mato","family":"Valenti\u0107","sequence":"additional","affiliation":[{"name":"Department of Fisheries, Apiculture, Wildlife Management and Special Zoology, Faculty of Agriculture, University of Zagreb, Sveto\u0161imunska cesta 25, 10000 Zagreb, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9786-5956","authenticated-orcid":false,"given":"Zvonimir","family":"Marijanovi\u0107","sequence":"additional","affiliation":[{"name":"Department of Food Technology and Biotechnology, Faculty of Chemistry and Technology, University of Split, Ru\u0111era Bo\u0161kovi\u0107a 35, 21000 Split, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0727-6662","authenticated-orcid":false,"given":"Igor","family":"Jerkovi\u0107","sequence":"additional","affiliation":[{"name":"Department of Organic Chemistry, Faculty of Chemistry and Technology, University of Split, Ru\u0111era Bo\u0161kovi\u0107a 35, 21000 Split, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,9,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Komosinska-Vassev, K., Olczyk, P., Ka\u017amierczak, J., Mencner, L., and Olczyk, K.
