The effects of processing on the functional, chemical and pasting properties of jackfruit seed flour were investigated. The values for dispersibility ranged from 75.75% to 85.75% with GJFSF (germinated jackfruit seed flour) being significantly different (p≤0.05) from the dried (control), autoclaved, boiled and roasted jackfruit seed flour samples. Oil absorption for the samples ranged from 150% to 300% with AJFSF (autoclaved jackfruit seed flour) and GJFSF being significantly different (p≤0.05) from the dried (control), boiled and roasted jackfruit seed flour samples. Swelling power ranged from 6.58% to 9.46% with Control (dried jackfruit seed flour) and GJFSF being significantly different (p≤0.05) from the autoclaved, boiled and roasted samples. Bulk density values ranged from 0.256g/ml to 0.327g/ml with GJFSF being significantly different (p≤0.05) from control, AJFSF, BJFSF and RJFSF samples. The color of the flour samples ranged from 74.76% to 82.59 % with Control being significantly different (p≤0.05) from the autoclaved, boiled germinated and roasted jackfruit seed flour samples. Water absorption capacity, solubility, least gelation concentration, moisture, crude fiber, ash and carbohydrates showed no significant differences (p≥0.05) in all the samples. Protein content ranged from 12.25% to 16.80% with RJFSF (roasted jackfruit seed flour) being significantly different (p≤0.05%) from the dried (control), autoclaved, boiled and germinated jackfruit seed flour samples. The crude fat ranged from 0.13% - 0.77% with dried (control), AJFSF and BJFSF (autoclaved and boiled jackfruit seed flour) being significantly different (p≤0.05) from the germinated and roasted samples. The starch content ranged from 26.55% to 36.03% with AJFSF being significantly different (p≤0.05) from the dried, boiled germinated and roasted jackfruit seed flour samples. Sugar content ranged from 0.50% to 2.48% with RJFSF being significantly different (p≤0.05) from the dried (control), autoclaved boiled and germinated samples. Amylose and amylopectin contents ranged from 15.72% to 23.79% and 76.21% to 84.28% with GJFSF and AJFSF being significantly different (p≤0.05) from BJFSF and RJFSF samples. The peak viscosity for the samples ranged from 743.50RVU to 4260RVU with RJFS being significantly different (p ≤0.05) from the control, AJFSF, BJFSF and GJFSF samples. Trough, breakdown, and final viscosity showed no significant difference (p≥0.05), while Setback viscosity ranged from 395.50RVU -1388RVU with Control and RJFS being significantly different (p≤0.05) for AJFSF, BJFSF and GJFSF samples. While the maximum pasting time and temperature was reached at 8.46mins and 93.90C respectively.
