| Summary: | The aim of the present study was to determine the optimum concentration of soy lecithin and gum arabic in producing drum-dried
jackfruit (Artocarpus heterophyllus) powder using response surface methodology (RSM). Jackfruit puree was dried using a double drum
drier set at 1 rpm, drum clearance of 0.01 in., and steam pressure of 2.3 bar. Soy lecithin and gum arabic were incorporated into jackfruit
puree at different concentrations ranged from 1% to 5% and 5% to 15%, respectively. Soy lecithin and gum arabic were significant factors
(at 95% confidence level) for moisture content, bulk density, Hunter L, a, b values and hedonic test during drum drying of jackfruit. A
second-order polynomial model was found for each of the significant response. The jackfruit puree formulation to produce a good quality
powder could be obtained by incorporating 2.65% of soy lecithin and 10.28% of gum arabic into the jackfruit puree (40% v/w water). |
