Abstract
The study on jackfruit seeds was undertaken for assessing its functional properties and
utilization of seeds for value added products. The seed flour was evaluated for its
physicochemical attributes, functional properties and bioactive compositions. It contains
higher amount of protein (16.46%), ash (2.12%), crude fat (1.52%), crude fiber (2.77%) and
lower carbohydrates (67.62%). The use of jackfruit seed flour in various product formulations
was investigated, viz., pasta, cereal bar, corn chips, pinni and juice. The quality characteristics
of the prepared products from jackfruit seed flour were evaluated. Pasta was enriched with
jackfruit seed flour at 6, 12, 18 and 24 per cent level, of which sample enriched at 18 per cent
level had best quality. Cereal bar, corn chips, pinni and enriched with jackfruit seed flour had
improved nutritional and sensory profile. Cereal bars were prepared by incorporation of
jackfruit seed flour at 15 and 30 per cent concentrations. High overall acceptability of bar
suggested that incorporation can be done to 30 per cent level without development of any off
flavour. Corn chips and pinni enriched at 6 and 30 per cent level respectively were found
most suitable with regard to its appearance, taste, texture and overall acceptability. Sensory
properties of the products enriched with jackfruit seed flour was comparable as the control
ones. The storage stability of pasta and corn chips for 4 months, cereal bar for 3 months and
pinni for 45 days at ambient storage conditions were investigated. During the storage of
products at ambient conditions, significant changes in quality parameters were observed.
Pasta was found acceptable after 4 months of storage while corn chips were acceptable till 3
months of storage period. Cereal bars were found acceptable for over 3 months of storage
period. Thus, the jackfruit seed has a lot of potential to be utilized in development of variety
of enriched and value-added products.
