Data is expressed as mean ± standard deviation. Values with different superscript in a row are significantly different (p <0.05). WB, white bread; WMB, wheatmeal bread, VB75 and VB100, breads with 75 g and 100 g pumpkin substitution. Means with different superscripts in a column are significantly different (p < 0.05). N= Number of replicates. L* indicates the lightness value, a* indicates the degree of redness, and b* indicates the degree of yellowness. A higher the L*, a*, and b* value means a higher degree of lightness, redness, and yellowness of the bread, respectively. A higher hardness, resilience, cohesion, gumminess, and chewiness value indicates a higher degree of bread crumb hardness, resilient, cohesion, springinessy, gumminess, and chewiness of the bread crumb, respectively, following the double compression measurements of using the texture analyser probe.
