L*—colour brightness; a*—colour in the range from green to red; b*—colour from blue to yellow. The values are given as mean ± SD (n = 9; triplicates of individual triplicates of pumpkin). The values followed by different superscripts (a–e) within the same column are significantly different (p < 0.05) from each other. Different letter superscripts (A,B) in each row indicate significant difference (p < 0.05).
