Abstract

The purpose of this study was to survey the attitude to consumer on snack product and investigate the effect of jackfruit seed starch on deep-fried snack product qualities. From consumer survey, the impact textural characteristics affecting purchase decision were crispness and puffiness. Saltiness and lipid or oil content affected purchasing behavior. Carrot was ingredient that consumer expected to add in developed snack. The 77% consumer demanded the developed snack from jackfruit seed starch. The effect of jackfruit seed starch on snack product quality was investigated by varying the ratios of wheat flour to jackfruit seed starch at 100:0, 75: 25, 50:50 and 25: 75. From microstructure analysis of snacks, it was found that, the amount of jackfruit flour increased, the number and size of air cell of snack products decreased. In terms of chemical quality, increasing jackfruit seed starch content of 0% to 75%, the oil content decreased from 27.49% to 19.55%. From sensory attributes analysis, the hardness and crispness of snack product increased as jackfruit seed starch increased (p£0.05) but significantly decreased oil absorption of snack product (p£0.05). From consumer acceptance using 7-point hedonic scale, the snack product prepared from the ratios of  wheat flour to jackfruit seed starch at 75:25 received the highest overall acceptance score. Keywords :  snack, jackfruit seed starch, crispness, oil absorption
