Plant-based mince texture: A review of the sensory literature with view to informing new product development.

Abstract

The texture of plant-based meat alternatives is a sensory attribute that holds a central value in consumer acceptability. The texture dimensions and drivers of liking for plant-based mince, a popular product within plant-based meats, are not yet fully established and literature in this area is limited. Consequently, the successful development and positioning of such products in the market next to traditional proteins is compromised, and improved product development guidelines are needed for the industry. This review aims to inform product development of what is currently known about plant-based mince texture and where the research gaps are, particularly with respect to sensory dimensions and drivers of liking, by reviewing the present landscape of relevant sensory literature. Potential texture sensory dimensions for plant-based mince, based on limited studies and seemingly aligning with conventional mince, are posited as juiciness, tenderness, firmness, and/or softness with a key driver of liking being juiciness, but this requires further validation utilizing robust sensory studies. A significant need exists to expand on the currently known texture dimensions and drivers alongside new ways that texture can be improved upon to more closely align to, or exceed, consumer expectations. Once this has been achieved, a robust sensory framework for developing plant-based mince products can be used to better position plant-based mince to effectively compete with traditional mince, and not merely cannibalize upon other brands, in the current market.
