Abstract

ORGANOLEPTIC CHARACTERISTICS OF ICE CREAM ADDING BY PURPLE SWEET POTATOES (Ipomea batatas L). This study was conducted to know about the use of purple sweet potatoes as an extender to ice cream on the organoleptic characteristics. The material used in this study were fresh milk, purple sweet potatoes and the ingredients for ice cream making. Four treatments tested in this study consisted of P0 (1000 ml of milk without purple sweet potatoes), P1 (1000 ml of milk plus purple sweet potatoes 150 g), P2 (1000 ml of milk plus purple sweet potatoes 300 g), P3 (1000 ml of milk plus purple sweet potatoes 450 g). This research used a complete randomized design and was tested by 35 of panelist to determine the organoleptic properties data of a purple sweet potato ice cream product. The data measured of in this research used hedonic scale. The variables measured consisted of color, flavor, texture, taste of ice cream. Determination of difference of average was done by DMRT test. The results of this study showed that the treatment was significant effect on color, flavor, texture and taste (P<0.01). The conclusion of this study based on organoleptic characteristics, the use of 450 g of purple sweet potatoes as an additive in 1000 ml of milk can be used on making of ice cream.
