This study reviews the foaming properties of plant proteins and how they are influenced by extraction processes, physical, chemical, and enzymatic treatments. Different approaches to improving the foaming properties of plant proteins, such as optimizing extraction conditions and modulating their interactions with other food components, are highlighted as having potential.
Background: Aerated food products are becoming increasingly popular among consumers due to their visual appeal and peculiar sensory properties. Foam formation and stabilization are typically achieved using clean label surface-active molecules such as proteins. In recent years, the need to address pressing global challenges like food security and sustainability has steered the attention of food companies towards the replacement of animal proteins with plant-based ones. This trend has promoted the development and commercialization of a variety of plant protein-enriched ingredients that differ widely in their techno-functionality. Scope and approach: The aim of this study was to provide a review of the foaming properties of selected plant proteins and to describe how these are influenced by the extraction processes as well as by physical, chemical and enzymatic treatments. Key findings and conclusions: The characterization of the foaming properties of plant proteins has been the subject of extensive research over the past couple of decades. However, drawing general conclusions based on the outcomes of different studies is a complex endeavor, even for protein ingredients derived from the same plant species. This is not only due to differences in terms of cultivars, environmental factors, farming practices and extraction processes, but also in the methods and conditions used to generate and analyze foams. Nevertheless, this review highlights the potential of different approaches to improve the foaming properties of plant proteins, including the optimization of extraction conditions, the use of physical, chemical and enzymatic treatments, and the modulation of their interactions with other food components.
