Nutritive compositions of locally available jackfruit seeds (Artocarpus heterophyllus) in Bangladesh

The nutritive value of jackfruit seeds was investigated using the following parameters-proximate composition and mineral composition. The aim of this study is to determine the physico-chemical properties of jackfruit seeds. Three types of jackfruits namely Khaja (green, hard and smooth, with juicy pulp and small seeds), Gala (rough, soft, with thin pulp, not very juicy, and large seeds) and Durosha (rough, soft, intermediate size of pulps and seeds) were taken under investigation. The fruits were cut, the seeds removed, sliced, dried at 60 °C for 24 hrs, packaged in polyethelyne bag and kept in a refrigerator (~20±2° C). The moisture content, dry matter and ash content was found around 21.10- 42.25%, 57.75- 78.90% and 2.13- 4.07% respectively among the varieties. A good amount of protein content was found in all varieties of jackfruit seeds, it ranged from 13-18%. Crude fibre content of seed varied from 1.56-2.60%. Jackfruit is a good source of many mineral contents like N, P, K, Ca, Mg, S, Zn, Cu etc. Starch content in seed was found from 12.86- 17.90%. The information achieved from the study could be helpful for the students, teachers, scientists who has been engaged with the biochemical analysis of different types of jackfruits in Bangladesh.
