Analysis of several techno-functional and sensory attributes upon egg allergen ingredient substitution by blood plasma powder in sponge cake

Animal blood is a by-product, which can be utilized in a value-adding way instead of being wasted. Allergen substitution is an obvious possibility because many properties of blood plasma are similar to egg white. Techno-functional and sensory attributes (water activity, moisture content, colour and texture related properties) were measured by instrumental methods. The allergenic egg powder can be substituted by non-allergenic blood plasma powder in sponge cakes, but the change in the ingredient has an effect on hardness and tolerating compressive stress until the breaking. In the case of water activity and moisture content, sponge cakes with blood plasma were as desirable as sponge cakes with egg.
