The principal objective of this study was to evaluate the quality characteristics of pound and sponge cakes prepared with Cucurbita maxima Duchesne (C. Maxima Duch.) puree, via physical and sensory examinations. The cakes were formulated by repalcing the egg with C. maxima Duch. puree at concentrations of 0, 10, 20 and 30%. C. maxima Duch. puree contained 87.91% water, 0.58% ash, 1.68% protein, 0.55% lipid, 1.02% fiber, and 8.26% carbohydrate. The physicochemical properties of the pound and sponge cakes evidenced similar patterns. The specific gravities of the pound and sponge cakes increased with increasing substitution levels, whereas the specific volumes were reduced. The hardness values of the pound and sponge cakes containing the C. maxima Duch. puree were higher than those of the controls. Substituting C. maxima Duch. puree for egg resulted in reduced lightness and increased redness in the cakes. Pound and sponge cakes with C. maxima Duch. puree evidenced higher moisture contents than the controls over 5 days of storage. Overall acceptances in sensory evaluation scored higher in the 20% substituted pound and sponge cakes.
