Furthermore variations of storage duration were 0 hours, 24 hours and 48 hours. Data were analyzed using Kruskal Wallis and T-Test Independent The result of research shows the influence of storage duration steamed sponge with a kind of substitution of purple sweet potato flour has the highest total number of microorganisms on the storage of 48 hours (2,83x106cfu / ml) and steamed sponge purple sweet potato puree substitution also had the highest total number of microorganisms on the storage of 48 hours (8, 31x105cfu / ml).
