Edible films are plastics that can be degraded by microorganismnisms and are made from renewable materials. The purpose of this study was to determine the characteristics of jackfruit and durian seed starches, improve the physical and mechanical properties of edible film from starch to characteristics physical properties edible film. The concentration of jackfruit and durian seed starches are 3%, 4%, and 5% with an addition of glycerol as a plasticizer. The durian seed starch edible films were 0.032-0.041 mm thinner than the edible film from jackfruit seed starch (0.035-0.043 mm) and the thickness increased as the starch concentration in the film making solution increased. At the same concentration level, jjackfruit seed starch resulted in a thicker film compared to film from the durian seed starch. Transparency of film was detected using UV-VIS and showed that the transparency of film decreased when the concentration of starch increased. Durian seed starch edible film showed that jackfruit seed starch edible film has a higher transmittance value compared to durian seed starch film. All films show a very low transmittance (below 23% at 550 nm); this opaque film can be applied for uses in food packaging for which transparency is not required. © Published under licence by IOP Publishing Ltd.
