Abstract

In this study, wheat breads including Spirulina platensis (SP) and protein extracts from Spirulina platensis (SPE) at levels of 0.125%, 0.25% and 0.50% were prepared and textural, volume, color and sensory properties were determined. Moreover, changes in total phenolic content (TPC), antioxidant activity (AOA) and in vitro protein digestibility (PD) of breads were investigated during in vitro digestion. The sample with the highest firmness value was control (919.4 g, p≤0.05). Breads with SP and SPE had higher volume than control (p≤0.05). The L* (52.2±1.0) and b* (18.9±0.2) values were the lowest for bread with SPE-0.25 (p≤0.05). The AOA of breads (SP-0.125, SP-0.5 and SPE-0.25) increased after in vitro gastric digestion (p≤0.05). The SPE-0.50 was the most preferable in terms of sensory properties. The SPE-0.125 had the highest TPC and breads including SPE at all levels had higher AOA than control and breads with SP after in vitro intestinal digestion (p>0.05).
