Abstract
High-moisture extrusion is the most cost-effective method for producing meat analogues with desired microstructure and textural characteristics, owing to its combined unit operations and customisable process conditions. An appropriate combination of extrusion conditions is crucial for obtaining high-moisture meat analogue (HMMA) products with the desired characteristics. In this study, we systematically investigated the effects of varying extrusion conditions, specifically temperature (130–160 °C) and screw speed (100–300 rpm), on the formation of fibrous structure of faba bean protein-based HMMA in the presence of brewers’ spent grain. Our findings indicate that higher screw speeds and temperatures significantly enhanced the phase separation, physical cross-linking, and fibrous structure formation, which improved textural attributes and increased water retention capacity. Importantly, the fibrous structure achieved through adjusting extrusion conditions did not adversely affect the digestibility of faba bean protein-based HMMA. By reporting the efficacy of the extrusion conditions in structuring fibrous meat analogues similar to chicken meat, this study demonstrates that a high-quality meat alternative product can be efficiently produced using two sustainable ingredients (faba bean protein and brewers’ spent grain) without any external modifiers.
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.
