Moreover, the abundant yield of purple sweet potatoes in Indonesia is not utilized optimally.

The next processes included mixing, pasteurization, homogenization, aging, and freezing. Thus, this study sought to examine the extent to which the consumer acceptability of the ice cream product made by using purple sweet potatoes as natural dyes and non-fat solids. The results suggested that purple sweet potato-based ice cream was accepted by the consumers from which 79% of them gave “like” response to the flavor, 81% gave “attractive” response to the color, 62% gave “fragrant” response to the aroma, 80.4% gave “soft” response to the texture, and 85.4% gave “like” response to the physical appearance.
