Abstract
The growing consumer demand for clean label food products has led to the search for alternatives to calcium-chelating salts in cheese powder production. Pulsed electric field (PEF) technology presents a promising green processing approach with its ability to disrupt casein networks. This study investigated the impact of PEF treatment on Cheddar cheese properties and the resulting model cheese emulsion. Response surface methodology revealed that pulse repetition and electric field strength are the primary parameters influencing the solubilization of calcium and phosphorus from the cheese matrix. Texture profile analysis indicated a notable reduction in cheese hardness with the application of PEF. Despite the significant impact of PEF on cheese structure, our study found no substantial alterations in the emulsion stability of cheeses treated with the applied PEF parameters. These promising results highlight the need for further exploration of alternative PEF parameters, such as different waveforms (i.e. exponential) or shorter pulse durations (nanoseconds), to unlock the full potential of PEF for clean label cheese powder production.
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.
