Impact of conventional and emerging processing methods on alternative breads- a comprehensive review and...

An increasing consumer demand for plant-based and high-protein options, motivated by health and sustainability, has resulted in a surge of food innovation in this area. Incorporating alternative plant sources, such as pulses and pseudocereals, has been proven to enhance the nutritional profile of baked products. However, these can also negatively impact the yeasted bread acceptability. In the bakery sector, it is crucial to consider how incorporating non-wheat ingredients influences product quality. Consequently, exploring effective treatments/processing methods becomes essential to minimize the impact of alternative plant ingredient additions. This review explores conventional and emerging processing approaches for alternative plant materials and discusses the nutritional value may be enhanced while maintaining high acceptability. A meta-analysis was undertaken to visualize the influence of plant processing technologies on product quality, specifically on loaf-specific volume and crumb texture. This review highlighted the importance of conventional processing methods when applied to bread. Additionally revealed the potential of emerging processing which can positively affect a loaf volume and texture when compared with non-processed plant ingredients. Such studies enabled the production of acceptable bakery products with higher levels of alternative ingredient incorporation. However, increased use of emerging technologies is dependent on further research and overcoming scaling-up difficulties.
