Quince fruit powder can be obtained from the waste of the edible product. In this study, we modified the powder with various solvents and investigated its application in Pickering emulsification. The crushed Chinese quince fruit possessed excellent Pickering emulsifying abilities when the water-soluble components were removed. In addition to cellulose, the powder contains hydrophilic pectin and hydrophobic lignin fibers. Similarly, a powder consisting of cellulose and a small amount of lignin without pectin, which was obtained by further solvent treatment, also showed high emulsification performance. Although these two powders had different fiber compositions, their water contact angles were almost equal, and their surface hydrophilicity was lower than that of the cellulose-only powder without emulsification ability.
