Hunter-lab color values of cake samples
All color data are expressed as Hunter L*, a*, and b* values corresponding to lightness, redness, and yellowness, respectively. Hunter-lab color values of cake contained substituted flour at different levels of watermelon rind and sharlyn melon peel powder are given in Table 6. Crust and crumb color of cakes varied with the quantity and the kind of the supplemented materials the crust became lighter (higher L*) as the watermelon rind and sharlyn melon peel powders level increased compared to that of control cake. No considerable differences in crust yellowness were found among the different watermelon rinds samples, while sharlyn melon peels samples exhibited higher b* values than the respective watermelon rinds samples, both gave higher b* values than the control cake sample.
