|
Effect of baking on the physicochemical and sensory properties was investigated using a model system of sponge cakes incorporated with Ecklonia cava powder as a value-added food ingredient. Ecklonia cava powder was incorporated into cake batter at 5 levels (0%, 2%, 4%, 6%, and 8%, w/w) by replacing equivalent amount of wheat flour. After appropriate mixing, sponge cakes were baked at 185oC for 20 min in an oven. The baked cakes were cooled to room temperature for 1 hr prior to all measurements. The specific gravity of batter increased gradually with increase in Ecklonia cava powder content. The specific volume of sponge cakes tended to decrease while baking loss increased. Volume of the cakes decreased with higher amount of Ecklonia cava powder in the formulation as indicated by the decrease in the volume index. Sponge cakes became darker and firmer with increase in Ecklonia cava powder content (p<0.05). Color, seaweeds smell, and taste were distinctively classified by the sensory analyses (p<0.05). Finally, correlation analysis indicated that level of Ecklonia cava powder incorporation was well-correlated with all the physicochemical and sensory properties studied except for a*-value and sensory firmness (p<0.05, p<0.01 or p<0.001).
