CHLORELLA VULGARIS İÇEREN AZ YAĞLI KURABİYELER: HAMUR REOLOJİSİ, FİZİKSEL, DOKUSAL VE DUYUSAL ÖZELLİKLER ÜZERİNE ETKİLERİ

Abstract

Microalgae are an enormous biomass used for fortification in foods that represent a promising source of protein. Enrichment of baked foods with microalgae is a challenge for its textural and structural impacts. In this study, dough rheology, physical, textural and sensorial properties of low-fat cookies with Chlorella vulgaris at various concentration (0.5, 1.5 and 3.0 %) were evaluated. Dry matter (93.20 to 94.89, %), protein (5.55 to 7.08, %), ash (0.47 to 0.55, %) and fat (12.35 to 13.37, %) contents of cookies were significantly increased with increasing microalgae concentration, whereas carbohydrate amount did not change significantly. The creep parameters, recovery behavior and viscoelasticity were increased with the addition of Chlorella biomass where results clearly showed more stiff dough structure. As the microalgae concentration increased, a significant color change (33.25, ΔE) with high hardness (198.69 up to 330.86, N) and fracturability (88.66 up to 165.18, N) properties were observed.
