| dc.description.abstract | Taro has high carbohydrate content. Taro is mostly consumed in the form of fresh tubers. To increase the utilization of Taro as a carbohydrate source in food, taro tubers should be processed into flour. Therefore, understanding the characteristics of taro flour is required to be able to handle taro flour properly during production storage, packaging, and processing. The objective of this study were to examine the physical and chemical characteristics of taro flour, and to determine the consumer preference level of taro cake. The results showed that yield of taro flour was 19.7%. The density was 0.534 g/ml and launch angle was 34º. The gelatinization temperature was relatively high, at 82.9ºC, due to high content of protein that inhibits the starch gelatinization. Peak viscosity of taro flour was 2865.3 cP. Taro flour was less stable during heating, this was indicated by a high value of breakdown viscosity i.e. 1155.7 cP. Setback viscosity was 636.3 cP. The largest part of the chemical composition was carbohydrates. The energy contained in taro flour worth was 369.04 kcal per 100 g taro flour. Taro sponge cakes were made in two levels of taro flour composition, i.e. 50% and 100%. It was resulted that taste, texture, aroma, pores, color of crumb, and crust color, sponge cake of 50% taro flour was more acceptable than 100%. | en |
