In this regard, analytical methods are necessary in order to determine specific targets. Among oxygen heterocyclic compounds (OHCs, that are furocoumarins, coumarins and polymethoxyflavones), only coumarin is subject to restriction by the Regulation (EC) No 1334\/2008 of the European Parliament. Furocoumarins are known for their phototoxicity and other side effects due to their dietary intake; however, an official limit about the maximum content of these compounds in food is still missing. The lack of information about the real amount of these compounds in food is responsible for the conflicting opinions about the introduction of an official limit. The HPLC-MS\/MS method here proposed, in combination with the linear retention index system, represents an innovative analytical strategy for the characterization of OHCs in citrus beverages. Several types of drinks were analysed in order to quantify 35 OHCs in total. This method is suitable for the quality control of OHCs in food and the obtained results may be considered as informative data useful for the regulatory authorities in the emission of new opinions and for a potential new regulation in this field.<\/jats:p>","DOI":"10.3390\/foods10071533","type":"journal-article","created":{"date-parts":[[2021,7,2]],"date-time":"2021-07-02T10:06:34Z","timestamp":1625220394000},"page":"1533","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":31,"title":["Dietary Intake of Coumarins and Furocoumarins through Citrus Beverages: A Detailed Estimation by a HPLC-MS\/MS Method Combined with the Linear Retention Index System"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3057-0285","authenticated-orcid":false,"given":"Adriana","family":"Arig\u00f2","sequence":"first","affiliation":[{"name":"Department of Chemical, Biological, Pharmaceutical and Environmental Sciences, University of Messina, 98168 Messina, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7887-7134","authenticated-orcid":false,"given":"Francesca","family":"Rigano","sequence":"additional","affiliation":[{"name":"Department of Chemical, Biological, Pharmaceutical and Environmental Sciences, University of Messina, 98168 Messina, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8229-1010","authenticated-orcid":false,"given":"Marina","family":"Russo","sequence":"additional","affiliation":[{"name":"Department of Chemical, Biological, Pharmaceutical and Environmental Sciences, University of Messina, 98168 Messina, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3234-7650","authenticated-orcid":false,"given":"Emanuela","family":"Trovato","sequence":"additional","affiliation":[{"name":"Chromaleont s.r.l., c\/o Department of Chemical, Biological, Pharmaceutical and Environmental Sciences, University of Messina, 98198 Messina, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paola","family":"Dugo","sequence":"additional","affiliation":[{"name":"Department of Chemical, Biological, Pharmaceutical and Environmental Sciences, University of Messina, 98168 Messina, Italy"},{"name":"Chromaleont s.r.l., c\/o Department of Chemical, Biological, Pharmaceutical and Environmental Sciences, University of Messina, 98198 Messina, Italy"},{"name":"Unit of Food Science and Nutrition, Department of Medicine, University Campus Bio-Medico of Rome, 00128 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8890-675X","authenticated-orcid":false,"given":"Luigi","family":"Mondello","sequence":"additional","affiliation":[{"name":"Department of Chemical, Biological, Pharmaceutical and Environmental Sciences, University of Messina, 98168 Messina, Italy"},{"name":"Chromaleont s.r.l., c\/o Department of Chemical, Biological, Pharmaceutical and Environmental Sciences, University of Messina, 98198 Messina, Italy"},{"name":"Unit of Food Science and Nutrition, Department of Medicine, University Campus Bio-Medico of Rome, 00128 Rome, Italy"},{"name":"BeSep s.r.l., c\/o Department of Chemical, Biological, Pharmaceutical and Environmental Sciences, University of Messina, 98168 Messina, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,7,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"599","DOI":"10.1016\/j.jpba.2009.09.030","article-title":"Simultaneous characterization and quantitation of 11 coumarins in Radix Angelicae Dahuricae by high performance liquid chromatography with electrospray tandem mass spectrometry","volume":"51","author":"Zheng","year":"2010","journal-title":"J.
