2-phenyl ethanol is a natural compound, which have many applications due to its nice fragrance, bacteriostatic
and antifungal character. However, it is difficult to keep it stable and it is highly volatile. In this work, chitosan
films with 2-phenyl ethanol were developed and inclusion complexes with cyclodextrins (CDs) were prepared in
order to have a controlled release of 2-phenyl ethanol. β-CD was selected to develop the inclusion complex since
it showed higher retention yield (45%, molar basis) than α- or γ-CDs. Chitosan films incorporated with β-CD:2-
phenyl ethanol were homogeneous, transparent and colorless, and showed high mechanical resistance.
Furthermore, the release results of the films without the inclusion complex indicated that 2-phenyl ethanol was
evaporated during the film preparation, and only an 8% of the total bioactive was retained in the film, while
more than 90% of 2-phenyl ethanol was retained in the films with the inclusion complex., Authors thank the Ministry of Science, Innovation and Universities

Atlantic horse mackerel (Trachurus trachurus) fillets were coated by gallic acid and chitosan solutions, including chitosan nanoparticles, and fish quality and shelf life were assessed during chilled storage for 13 days. All chitosan-containing coatings decreased microorganisms’ growth in more than 2 log cycles up to late storage stages; however, those with chitosan nanoparticles resulted to be more effective, probably due to a greater contact surface with fish muscle. Furthermore, the lowest total volatile basic nitrogen (TVB-N) values, as well as pH values below 7, were found for horse mackerel fillets coated by those solutions with chitosan nanoparticles. Additionally, horse mackerel fillets coated by solutions with chitosan nanoparticles also showed the lowest thiobarbituric acid reactive substances (TBARS) values, maybe owing to a more sustained release of gallic acid. In this regard, it is worth noting that, although gallic acid solution showed no antimicrobial activity, this prevented lipid oxidation and, therefore, preserved color and texture during the chilling storage., Authors thank the Basque Government (PA20/02), the Provincial Council of Gipuzkoa (Department of Economic Development, the Rural Environment and Territorial Balance), the University of the Basque Country (GIU18/154), and the Agencia Estatal de Investigación (AEI) and the European Regional Development Fund (FEDER), through projects AGL2017-84161 and RTI2018-097100-B-C22, for financial support.
