Abstract. Edible film are plastics which can be degraded by micro-organisms and is made from
renewable materials. The purpose of this study was to determine the characteristics of jackfruit
and durian seed starch, improve the physical and mechanical properties of edible film from
starch to characteristics physical properties edible film. The concentration of jackfruit and
durian seed starch are 3%, 4% and 5% with addition of glycerol as plasticizer. Thickness of
durian seed starch edible films were about 0.032-0.041 mm slightly thinner than edible film
from jackfruit seed starch edible film (0.035 – 0.043 mm) and the thickness increase as the
starch concentration in film making solution increase. In the same concentration level, jackfruit
seed starch resulted a thicker film compare to film from durian seed starch. Transparency of
film were detected using UV-VIS and show the transparency of film decrease when the
concentration of starch increase. Durian seed starch edible film showed that jack jackfruit seed
starch edible film has higher transmittance value compare to durian seed starch film. All films
show a very low transmittance (below 23% at 550 nm), this opaque film can be applied for food
that transparent is not required.
