PENGARUH PENGGUNAAN PATI GANYONG (Canna edulis) DAN EKSTRAK DAUN SUJI (Dracaena angustifolia) TERHADAP KARAKTERISTIK BOLU KUKUS

The purpose of this study was to determine the effect of using canna starch (Canna edulis) and suji leaf extract (Dracaena angustifolia) on the physical, chemical and sensory characteristics of steamed sponge. This research was conducted at the Laboratory of Chemical Agricultural Products and the Sensory Laboratory of the Department of Agricultural Technology, Faculty of Agriculture, Sriwijaya University, Indralaya was conducted from January to November 2019. This study used Factorial Completely Randomized Design with two treatment factors, namely canna starch concentrations (10%, 15% and 20%) and concentrations of suji leaf extract (2% and 4%). The parameters observed included physical characteristics (color dan volume expansion), chemical characteristics (water content and protein content) and sensory tests using hedonic tests (color, texture, taste and aroma). The results showed that canna starch concentration and suji leaf extract significantly affected the value of greenness (a*), volume expansion and water content but had no significant effect on the value of lightness (L*) and yellowness value (b*). The interaction between the treatment canna starch concentration and suji leaf extract significantly affected the value of greenness (a*), yellowness value (b*) and water content but it had no significant effect on the volume expansion. The best treatment was based on organoleptic test. The most prefered treatment was steamed sponge cake with 10% canna starch and 4% suji leaf extract.
