Abstract

Abstract. This study was aimed to find the optimal formulation for making goat milk ice cream using suweg tuber flour as stabilizer to substitute gelatine commonly used in making ice cream. In order to find the best formulation, ice cream were evaluated organoleptic for its color, texture, taste, aroma, and overall acceptance. While the melting time and overrun were determined objectively. The proportions of suweg tuber flour in the manufacture of goat milk ice cream were 0%, 2%, 4%, 6%, 8%, and 10%, as a comparison, 0.5% gelatine was used. The color and texture were evaluated using scoring test, while the taste, aroma and overall acceptance were evaluated using hedonic test (preference) performed by 30 trained panels for each test. The data were tested for their homogeneity using Bartlett test and the aditivity was tested using Tuckey test. Then the data were analysed for variance to find the effect of the treatments, and further analysed using Least Significant Difference (LSD) test. All tests were carried out at the level of 1% or 5%. The results showed the color, taste and aroma, and overall acceptance of ice cream was significantly affected by treatments. The most preferred The highest score for overall acceptance was found in goat milk ice cream treated with 2% suwed tuber flour which was 8.85 (most preferred) . Whereas the highest value for melting time and overrun were found in goat milk ice cream treated with 10% suweg tuber flour, which were 24.5 minutes, 80.5%.
