ABSTRACT
Biopolymer packages have gained more attention of food scientists and technologists mainly due to environmental pollution, food safety, health concerns and economic limitations related with synthetic or traditional packages. Buckwheat, a pseudocereal and starch, is the major component of its seed. In the present research work, starch was isolated from buckwheat grains and modified by acetylation using vinyl acetate and heat-moisture treatment at 100°C for 6 h. Edible films prepared using native and modified starches of buckwheat were evaluated for various properties. Hydrothermal treatment of starch decreased water solubility and water vapour permeability of starch film and contradictory results were observed in acetylated starch films. Both the modification treatments increased tensile strength of buckwheat starch films.
Key words : Buckwheat, hydrothermal, acetylation, starch, films
