Colour Transition Dynamics of Commercial Plant- and Animal-Based Meat Analogues.

ABSTRACT: The inferior visual sensory attributes, particularly colour, of plant-based burgers, remain a barrier to enhancing consumer acceptance and uptake in the global market. This study aimed to comprehensively profile the colour transition dynamics at varying internal temperatures (uncooked, 35 °C, 55 °C, 75 °C, and 85 °C) of four distinct commercial plant-based (PB) and six animal-based (AB) burgers, and to identify key "colour gaps" for improvement. Raw beef burgers appeared red with higher positive a* values (redness), whereas v2food, vEEF, and Beyond burgers showed comparatively higher b* (yellowness) and c* (chroma) values both externally and internally. The sample Impossible PB burgers had the lowest colour differences (∆a*, ∆b*, ∆c*, and ∆<
