Nanostructured biopolymers (NBs) emerge as a promising alternative for PE stabilization owing to their remarkable biocompatibility, abundant availability, and low cost. To explore this potential, a study is herein presented, in which cellulose nanocrystals (CNCs), both type I and type II allomorphs, and chitin nanocrystals (ChNCs) were used for stabilizing oil-in-water PEs prepared by the use of ultrasound. Sunflower oil was selected as the oil phase as it offers the advantages of being edible, renewable, and inexpensive. By utilizing ζ-potential, static light diffraction, and visual observations, we determined the optimal oil/water ratio for each type of NB to obtain stable emulsions after 14 days. The optimized PEs were used to form bacterial nanocellulose composites through emulsion templating. To our knowledge, this study represents a pioneering work in exploiting oil-in-water PEs for this approach. Additionally, it entails the first utilization of nonmercerized type II CNCs as stabilizers for PEs, while also establishing a direct comparison among the most relevant NBs. The resulting composites exhibited a unique morphology, composed of larger pores compared to standard bacterial nanocellulose aerogels. These findings highlight the notable potential of NBs as stabilizers for PEs and their ability to generate green nanocomposites with tailored properties. info:eu-repo/grantAgreement/ES/DGA/T03-23R info:eu-repo/grantAgreement/ES/MICINN-AEI/PID2019-104272RB-C51/AEI/10.13039/501100011033 info:eu-repo/grantAgreement/ES/MICINN PID2020-120439RA-I00 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 4.9 2023 BIOCHEMISTRY & MOLECULAR BIOLOGY 66 / 313 = 0.211 2023 Q1 T1 CHEMISTRY, MULTIDISCIPLINARY 68 / 231 = 0.294 2023 Q2 T1 1.179 2023 Medicine (miscellaneous) 2023 Q1 Physical and Theoretical Chemistry 2023 Q1 Computer Science Applications 2023 Q1 Inorganic Chemistry 2023 Q1 Spectroscopy 2023 Q1 Organic Chemistry 2023 Q1 Molecular Biology 2023 Q2 Catalysis 2023 Q2 8.1 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Fuentes, Laura Berdejo, Daniel Universidad de Zaragoza (orcid)0000-0001-5053-8309 González-Domínguez, José M.
