Amaranthus paniculatus (Rajgeera) a non-conventional source of starch: effect of oxidation and heat moisture treatment and its application in edible film

Popis výsledku v původním jazyce

The main objective of this study was to carry out modification of Amaranthus starch (via oxidation and heat moisture treatment (HMT)) followed by the formation of edible films. The films were evaluated for physicochemical and mechanical properties. The carboxyl content of native and HMT starch was found to be similar whereas it was higher (0.1 COOH/100GU) for the oxidized sample. The solubility was found to be higher in modified starch samples (76.44 %) as compared to native (62.58 %) but swelling power was higher for native starch (50.43 g/g) as compared to modified samples. The tasting temperature of native starch, oxidized, and heat moisture-treated starch was found to be 75.09 °C, 76.10 °C, and 89.36 °C, respectively. Edible films were prepared and studied for physicochemical and mechanical. The tensile strength of amaranth starch films was enhanced by both modification procedures, whereas only HMT increased the water vapor permeability, and oxidation had the opposite effect. Modification treatments resulted in the reduction of water solubility of the films. The HMT film showed some advantages over the oxidized film and native starch films in terms of mechanical properties. The present study conclude that modified starches showed better properties than native starch.
