In vitro digestibility of edible films from various starch sources

Abstract
Banana, maize, potato and sagu starches were boiled in the presence or absence of plasticizer (glycerol), producing edible films. In vitro digestibility features, amylose content and amylopectin gel filtration behavior of films and parent starches were evaluated. Available starch contents were lower in glycerol-containing films, due to dilution by the plasticizer. Total resistant starch increased in the maize starch-based film but decreased markedly in those prepared from the other starches. Amylose content of banana starch (∼40%) was about double those of the other starches. Nonetheless, all starch films exhibited similar retrograded resistant starch content. Although film production led to increased α-amylolysis rates, these were further... (More)
Banana, maize, potato and sagu starches were boiled in the presence or absence of plasticizer (glycerol), producing edible films. In vitro digestibility features, amylose content and amylopectin gel filtration behavior of films and parent starches were evaluated. Available starch contents were lower in glycerol-containing films, due to dilution by the plasticizer. Total resistant starch increased in the maize starch-based film but decreased markedly in those prepared from the other starches. Amylose content of banana starch (∼40%) was about double those of the other starches. Nonetheless, all starch films exhibited similar retrograded resistant starch content. Although film production led to increased α-amylolysis rates, these were further augmented by additional film heating, thereby indicating that film-manufacture did not promote complete starch gelatinization. Gel filtration chromatography suggested amylopectin depolymerization after film-making, which may also increase digestion kinetics. The presence of glycerol in the films slowed down starch digestion, a feature of potential dietetic use. (Less)
