Scanning Electron Microscopy data of plant protein–inositol hexaphosphate microcapsules produced from anthocyanin-containing double emulsions
Description
This dataset contains source scanning electron microscopy (SEM) data supporting the study “Stabilization of double emulsions with anthocyanins using a plant protein–inositol hexaphosphate complex” by Kurek, Pokorski, Custodio-Mendoza, Aktas, Środa, and Łopusiewicz (2025), published in the Journal of the Science of Food and Agriculture, 105(14), 8071–8082 (DOI: 10.1002/jsfa.70054). The study investigated plant protein–inositol hexaphosphate complexes as stabilizing and encapsulating systems for anthocyanin-containing water-in-oil-in-water (W/O/W) double emulsions. Pea and rice proteins were used to form complexes with inositol hexaphosphate, and different formulation ratios were evaluated to determine their influence on the properties of the resulting encapsulation systems. The deposited data consist of original SEM micrographs obtained during morphological characterization of the dried microcapsules. Eight formulation variants are represented, including systems based on either rice protein or pea protein, protein-to-inositol hexaphosphate ratios of 1:1 and 2:1, and wall-material-to-emulsion ratios of 1:2 and 1:4. The SEM images provide direct information on particle morphology, surface characteristics, particle size heterogeneity, aggregation, and the overall microstructure of the dried encapsulation systems. The micrographs show predominantly rounded or approximately spherical structures, with differences in particle dimensions, surface appearance, and aggregation depending on the protein source and formulation conditions. The source images retain the original instrumental information, including magnification and scale bars, and constitute underlying imaging data supporting the morphological analysis reported in the associated publication. Comparison of the eight formulations enables assessment of how protein type, protein-to-inositol hexaphosphate ratio, and wall-material-to-emulsion ratio influenced the microstructure of the obtained particles. These SEM data complement the physicochemical, stability, and encapsulation results presented in the publication and provide direct visual evidence of the structures formed by the investigated plant protein–inositol hexaphosphate systems. The dataset is made openly available to improve transparency, traceability, reproducibility, and potential reuse of the morphological data underlying the published study.
