3.3. Color
Table 1 shows the results of color measurements of fresh
and dried banana samples. The L color parameter indicates
whiteness of the product. The b color parameter measures
the yellowness of the product. The a parameter is reported
as a reference even though it is not closely related to the color
quality of dried bananas. Preferred colors are light or light
golden color. In general, the drying treatment resulted in significantly
improved whiteness (increased L value). But the yellowness
of IR dried samples was stronger than the fresh and
regular freeze-dried samples resulting in a golden color tone
of dried products.
