    Harnessing Pulse Proteins as Soy Protein Substitutes in Spreadable Cheese Analogues: Exploring Correlations Among Protein Techno-Functionality, and Cheese Textural, Rheological and Sensory Properties
    (Elsevier Sci Ltd, 2026) Cavdaroglu, Elif; Topcuoglu, Meryem; Acar, Eda; Polat, Nil Yaren; Berk, Berkay; Cavdaroglu, Cagri; Yemenicioglu, Ahmet
    This study aimed at comparing techno-functional properties of faba bean (FBP), pinto bean (PBP), cowpea (CPP) and mung bean (MBP) proteins with commercial soy protein isolate (SPI), and exploring their correlations with textural, rheological and sensory properties of plant protein-based spreadable cheese analogues. FBP and MBP showed the best solubility between pH 3.0 and 11.0. The highest and the lowest water and oil (OAC) absorption capacities were observed for SPI and MBP (7.78 and 0.79 g H2O/g), and PBP and SPI (7.79 and 3.55 g oil/g). Protein's least gelling concentrations (LGC) ranged from 10 % (SPI) to 18 % (FBP). CPP, MBP, and PBP formed harder, gummier gels at >= LGC than SPI and FBP. Pre-gels of PBP and CPP at <= LGCs showed the highest consistency and viscosity indexes. Proteins showed similar emulsification. Cheese analogue from SPI (SPIC) showed the highest firmness (37.5 N) and work to shear for spreadability (57.5 N s), followed by cheese analogues of other proteins such as MBPC, CPPC, FBPC, and PBPC in descending order. The highest and lowest elastic (G ') and viscous (G '') moduli were obtained for MBPC (G' = 4353 and G"= 1277) and PBPC (G' = 377 Pa and G"= 98 Pa). OAC of proteins correlated with cheese analogues' firmness (r =- 0.918), work to shear for spreadability (r =- 0.910), and stickiness (r =- 0.894). Tan delta (G"/G ') of cheese analogues correlated with work to shear for spreadability (r = 0.986). SPIC and FBPC received the highest overall liking scores correlated mainly with appearance, color and taste. Correlating protein techno-functionality in cheese analogue opens new horizons for effective utilization of pulse proteins as soy protein substitutes.

    Utilization of Black Cumin (nigella Sativa L.) Cake Proteins as a Sustainable Food Ingredient: a Comparative Study With Commercial Proteins for Antioxidant, Techno-Functional and Vegan Cheese Properties
    (Elsevier Sci Ltd, 2025) Cavdaroglu, Elif; Kayi, Hilal; Budak, Yaren Buse; Berk, Berkay; Yemenicioglu, Ahmet
    This study aimed to compare the antioxidant, techno-functional and vegan cheese properties of black cumin cake protein concentrate (BPC) with those of commercial proteins. The BPC (63% protein, w/w) showed greater antioxidant potential (TEAC: 247 mu mol Trolox/g; ORAC: 211 mu mol Trolox/g; iron chelation capacity: 35.5 mu mol Trolox/g) than potato protein isolate (PPI), but comparable antioxidant potential with soy protein isolate (SPI). The BPC had slightly lower water binding capacity (7 g/g) than SPI (8.8 g/g), but 1.7 and 1.9-fold higher oil binding capacity (5.4 g/g) than PPI and SPI, respectively. All proteins showed similar emulsion capacity (EC) and stability (ES) at high protein concentrations (>= 1%), but BPC showed the highest EC and ES at low protein concentrations (<= 0.5%). BPC showed higher least gelling concentration (LGC: 14%) than PPI and SPI (LGCs for both 10%). However, the texture profile analysis showed that the heat-induced gels of BPC were firm but easily chewable. Moreover, BPC gels showed the highest springiness and resilience. The BPC-based spreadable vegan cheese was softer (firmness: 5.52 N), more easily spreadable (spreadability value: 6.23 N s), but less adhesive and sticky than SPI- and PPI-based spreadable vegan cheeses. SPI-based cheese showed the highest viscoelastic moduli followed by PPI and BPC with similar viscoelastic moduli. SPI-based cheese demonstrated the most favorable sensory properties, but BPC showed acceptable overall sensory properties. This work proved that black cumin proteins could be utilized to novel spreadable black vegan cheese. Further studies are needed to develop novel black-colored vegan food such as black milk, ice-cream, sausage, cake, crackers etc.
