Abstract
This study was aimed to investigate the effects of four oil phases with different fatty acid compositions and oil-soluble substances (including sunflower oil, SO, rich in C18 polyunsaturated fatty acids (PUFAs); extra virgin olive oil, OO, rich in oleic acid; virgin coconut oil, CO, rich in lauric acid; and palm oil, PO, rich in palmitic acid) on the properties of oil-water interfaces and W1/O/W2 double emulsions stabilized by Pleurotus geesteranus protein particles (PPIP). The results showed that the fatty acid compositions and oil-soluble substances in these oils can modify the surface hydrophobicity of PPIPs in situ, affecting their adsorption, rearrangement, and assembly behavior at the oil-water interface, and ultimately regulating double emulsion formation. Particles at the SO-water interface exhibited slow adsorption but rapid rearrangement behavior, forming an elastic interfacial film with the highest interfacial pressure. The OO-derived components conferred the highest hydrophobicity to the particles in situ, resulting in strong adsorption capacity but lower assembly ability that the most rigid structure was formed. At the CO-water interface, particles showed the fastest adsorption behavior and assembled into large aggregates, exhibiting the highest modulus. Particles at the PO-water interface exhibited the slowest adsorption rate and formed an interfacial film with the lowest viscoelastic modulus and weakest tangential interactions. The differences in particle behavior at these oil-water interfaces also influenced the formation of W1/O/W2 double emulsions. For example, the double emulsions formed with OO contained the highest content of W1/O droplets, followed by SO and CO, with PO having the fewest.
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.
