Starches used in food industry are extracted from roots, tubers and cereals. Seeds of jackfruit are abundant
and contain high amounts of starch. They are discarded during the fruit processing or consumption
and can be an alternative source of starch. The starch was extract from the jackfruit seeds and characterised
to chemical, morphological and functional properties. Soft and hard jackfruit seeds showed starch
content of 92.8% and 94.5%, respectively. Starch granules showed round and bell shape and some irregular
cuts on their surface with type-A crystallinity pattern, similar to cereals starches. The swelling power
and solubility of jackfruit starch increased with increasing temperature, showing opaque pastes. The soft
seeds starch showed initial and final gelatinisation temperature of 36 C and 56 C, respectively; while
hard seeds starch presented initial gelatinisation at 40 C and final at 61 C. These results suggest that
the Brazilian jackfruit seeds starches could be used in food products.
