    Techno-Functional and Antioxidant Properties of Chickpea Proteins Interacted with Green Tea Phenolics-Exploring Benefits for Gel and Emulsion-Based Vegan Foods
    (Elsevier, 2025) Kavur, Pelin Baris; Sahin, Damla Oyku; Cavdaro Glu, Elif; Buyuk, Miray; Cakitli, Gamze; Hamzaoglu, Fatmagul; Yemenicioglu, Ahmet
    This study aimed at exploiting protein-polyphenol interactions to enhance techno-functional and antioxidant properties of chickpea proteins. For this purpose, prior to protein extraction, chickpeas were rehydrated in green tea infusion (GTI). Extracted chickpea proteins (CPCGTI) contained free (90.7 mu g/g) and bound (32.0 mu g/g) green tea phenolics (e.g., gallic acid, catechin, epigallocatechin 3-gallate, epicatechin 3-gallate). A close association between chickpea protein and green tea polyphenols was determined considering pH-solubility profile of CPCGTI. CPCGTI showed superior antioxidant potential (6.5-fold), water/oil absorption capacity (1.4-1.5-fold), and gel firmness than control chickpea protein (CPCC). Edible films of CPCGTI also showed 2.4-fold higher antioxidant capacity than those of CPCC. CPCGTI and CPCC showed similar SDS-PAGE patterns, but different alpha-helix and beta-sheet contents evaluated by FTIR. CPCGTI gave thick, creamy and stable mayonnaise while CPCC failed to form mayonnaise. The coconut milk pudding with CPCGTI showed better gelation than that with CPCC. However, foods with CPCGTI had a darker color than those with CPCC. CPCGTI is a novel, highly functional ingredient for manufacturing plant-based food and edible packaging.

    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.
