Universidad de Zaragoza Application of SERS to the determination of butylated hydroxyanisole in edible and essential oils 2015 Access copy available to the general public Unrestricted Surface-enhanced Raman scattering (SERS) has been applied to the determination of the antioxidant butylated hydroxyanisole (BHA), commonly used in fatty foods and oils to prevent their oxidation. The use of SERS Raman microscopy with an inexpensive homemade silver substrate allowed the direct determination of BHA in oils without any sample handling. Several edible and essential oils (used as flavorings) have been considered for this purpose. The experimental conditions, the peculiarities of each type of oil, and the characteristics of silver substrate, including scanning electron microscopy (SEM) analysis, are shown and discussed. info:eu-repo/grantAgreement/ES/MEC/AP-2012-2716 info:eu-repo/grantAgreement/ES/MINECO/AGL2012-37886 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 0.482 2015 SPECTROSCOPY 41 / 43 = 0.953 2015 Q4 T3 0.165 2015 Analytical Chemistry 2015 Q4 Spectroscopy 2015 Q4 Atomic and Molecular Physics, and Optics 2015 Q4 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0002-6607-1309 Salafranca, J.
