Preparation of greaseproof paper coated with cationic-acetylated glutinous rice starch for food packaging.

ABSTRACT: Developing safe and environmentally friendly food packaging paper remains a major technical challenge. The utilization of bio-based polymers to produce paper-based packaging materials is an important focus in the food industry. In this study, cationic-acetylated starch was adopted as a raw material and combined with chitosan to prepare novel greaseproof coating materials. Scanning electron microscope (SEM) revealed that the surface of uncoated paper exhibited a fibrous network structure. In contrast, the coated paper showed a smooth surface with the fibrous texture completely covered. The oil resistance grade of the paper increased from 0 to 12, demonstrating excellent greaseproof performance. In addition, the water vapor transmission rates (WVT) for uncoated paper and coated paper are 258
