    Effect of dual modifications with ultrasonication and succinylation on Cicer arietinum protein-iron complexes: Characterization, digestibility, in-vitro cellular mineral uptake and preparation of fortified smoothie
    (Elsevier, 2024) Patil, Nikhil Dnyaneshwar; Bains, Aarti; Kaur, Sawinder; Yadav, Rahul; Goksen, Gulden; Ali, Nemat; Alasmari, Abdullah F.
    The research aimed to evaluate the effect of ultrasonication and succinylation on the functional, iron binding, physiochemical, and cellular mineral uptake efficacy of chickpea protein concentrate. Succinylation resulted in significant improvements in the water-holding capacity (WHC) (25.47 %), oil-holding capacity (OHC) (31.38 %), and solubility (5.80 %) of the chickpea protein-iron complex. Mineral bioavailability significantly increased by 4.41 %, and there was a significant increase in cellular mineral uptake (64.64 %), retention (36.68 %), and transport (27.96 %). The ferritin content of the succinylated chickpea protein-iron complex showed a substantial increase of 66.31%. Furthermore, the dual modification approach combining ultrasonication and succinylation reduced the particle size of the protein-iron complex with a substantial reduction of 83.25 %. It also resulted in a significant enhancement of 51.5 % in the SH (sulfhydryl) content and 48.92 % in the surface hydrophobicity. Mineral bioavailability and cellular mineral uptake, retention, and transport were further enhanced through dual modification. In terms of application, the addition of single and dual-modified chickpea protein-iron complex to a fruit-based smoothie demonstrated positive acceptance in sensory attributes. Overall, the combined approach of succinylation and ultrasonication to the chickpea protein-iron complex shows a promising strategy for enhancing the physiochemical and techno-functional characteristics, cellular mineral uptake, and the development of vegan food products.

    Exploration of Calocybe indica mushroom phenolic acid-kidney bean protein complex: Functional properties, amino acid profiles, in-vitro digestibility, and application in vegan product development
    (Elsevier, 2024) Patil, Nikhil Dnyaneshwar; Thakur, Sweezee; Bains, Aarti; Kaur, Sawinder; Ali, Nemat; Arora, Rahul; Parvez, Mohammad Khalid; Gökşen, Gülden; Janghu, Sandeep; Chawla, Prince
    The study evaluates the interaction between Calocybe indica mushroom polyphenols (phenolic acid) and kidney bean protein (KBPM), aiming to enhance vegan food quality. The mushrooms exhibited a carbohydrate content of 3.65%, an antioxidant activity of 55.04 ± 0.17%, and a phenolic content of 4.86 mg GAE/g. Caffeic and cinnamic acids were identified through high-pressure liquid chromatography. Various concentrations of KBPM were tested at phenolic acid concentrations of 0.025, 0.050, 0.1, 0.2, 0.4, 0.8, and 1%, among these, KBPM 0.2 demonstrated the highest binding efficiency of 99.40 ± 0.05%. Notably, this complex improved the protein's functional properties, such as solubility by 11.43%, water and oil holding capacities by 10.62% and 22.04%, and emulsion capacity and stability by 3.69% and 5.83%, respectively, compared to the native protein. The protein-phenolic acid complex also enhanced thermal stability, surface charge, amino acid content, and reduced particle size compared to native protein. These enhancements also improved protein digestibility and sensory attributes in a fruit-based smoothie.

    Influence of dual succinylation and ultrasonication modification on the amino acid content, structural and functional properties of Chickpea (Cicer arietinum L.) protein concentrate
    (Elsevier Sci Ltd, 2024) Patil, Nikhil Dnyaneshwar; Bains, Aarti; Kaur, Sawinder; Yadav, Rahul; Ali, Nemat; Patil, Sandip; Goksen, Gulden
    Chickpea protein, a valuable plant -based source, offers versatile applications, yet the impact of modifications like succinylation and ultrasonication on its properties remains unclear. This study explored dual succinylation and ultrasonication modification to enhance its functionality and application. Modified chickpea protein with a degree of succinylation of 96.75 %, showed enhanced water holding capacity 39.83 %, oil holding capacity 54.02 %, solubility 7.20 %, and emulsifying capacity 23.17 %, compared to native protein. Despite reduced amino acid content (64.50 %), particularly lysine, succinylation increased sulfhydryl by 1.74 %, reducing hydrophobicity (Ho) by 41.87 % and causing structural changes. Ultrasonication further reduced particle size by 82.57 % and increased zeta potential and amino acid content (57.47 %). The dual-modified protein exhibited a non-significant increase in antimicrobial activity against Staphylococcus aureus (25.93 +/- 1.36 mm) compared to the native protein (25.28 +/- 1.05 mm). In conclusion, succinylation combined with ultrasonication offers a promising strategy to enhance chickpea protein's physicochemical properties for diverse applications.
