Nonlinear rheological behavior and quantitative proteomic analysis of wheat aqueous phase protein at the air-water interface
Air-water interface stabilization plays a pivotal role in foam formation and gas cell stabilization in fermented wheat-based products such as bread. However, the nonlinear interfacial rheological behavior of wheat aqueous phase proteins and its correlation with protein structure remains poorly understood. This study investigated the whole process of film formation and stabilization of wheat aqueous phase protein (WAP) and its ethanol fraction (ES) and non-ethanol fraction (NES) at the air-water interface. The physicochemical characteristics, interfacial adsorption behavior, and nonlinear interfacial rheology of each fraction were evaluated, and proteomic analysis was performed to uncover molecular mechanisms. The results showed that ES exhibited smaller particle size (412.63 ± 44.53 nm) and higher surface hydrophobicity (592.79 ± 32.81), enabling rapid adsorption at the air-water interface, which contributed to its superior foaming capacity (184.73 ± 12.34 %). In contrast, NES exhibited higher viscosity (1.81 ± 0.01 mPa s), which slowed down liquid drainage in the foam's Plateau region, contributing to enhanced foam stability. Interfacial dilatational rheology revealed that ES formed a stiff, solid-like interface, the ES foam with superior resistance to interfacial rupture. The proteomics analysis demonstrated that all sample shared the similar protein components, with prolamins (Gamma gliadin) playing a crucial role in ES foam formation and stabilization. This study provides new insights into the dynamic interfacial behavior of wheat proteins and their roles in foam stabilization, offering theoretical guidance for protein engineering in cereal-based aerated foods.
期刊介绍:
Food Hydrocolloids publishes original and innovative research focused on the characterization, functional properties, and applications of hydrocolloid materials used in food products. These hydrocolloids, defined as polysaccharides and proteins of commercial importance, are added to control aspects such as texture, stability, rheology, and sensory properties. The research's primary emphasis should be on the hydrocolloids themselves, with thorough descriptions of their source, nature, and physicochemical characteristics. Manuscripts are expected to clearly outline specific aims and objectives, include a fundamental discussion of research findings at the molecular level, and address the significance of the results. Studies on hydrocolloids in complex formulations should concentrate on their overall properties and mechanisms of action, while simple formulation development studies may not be considered for publication.
The main areas of interest are:
-Chemical and physicochemical characterisation
Thermal properties including glass transitions and conformational changes-
Rheological properties including viscosity, viscoelastic properties and gelation behaviour-
The influence on organoleptic properties-
Interfacial properties including stabilisation of dispersions, emulsions and foams-
Film forming properties with application to edible films and active packaging-
Encapsulation and controlled release of active compounds-
The influence on health including their role as dietary fibre-
Manipulation of hydrocolloid structure and functionality through chemical, biochemical and physical processes-
New hydrocolloids and hydrocolloid sources of commercial potential.
The Journal also publishes Review articles that provide an overview of the latest developments in topics of specific interest to researchers in this field of activity.
