Abstract
SummaryPomace from fruit juice production is a by‐product with a high fibre and bioactive compound content. It is commonly used as animal feed, so using it in food brings added value. The present study assessed the effect of using black currant and aronia pomace to replace either part of the flour, fat or sugar in sponge cakes. Batters in which sugar was replaced showed the highest viscosity. On the other hand, flour replacement led to batters with the lowest viscosity and gave place to softer cakes with fewer but larger‐sized air cells. Sugar replacement conferred greater hardness and a larger number of small air cells. In general, fat replacement gave rise to intermediate crumb texture and structure properties in comparison with flour and sugar replacements. In vitro starch digestion showed that the flour‐replaced sponge cakes possessed the lowest hydrolysis index and glycaemic index values. The sponge cakes with the different replacements were well accepted by consumers, who expressed a high level of buying intention for all of them.
