According to the
results, drying time was between 18 and 38 min at drying temperatures of
60–80C. The lightness and yellowness of the dried mint leaves were significantly
increased when compared with fresh samples. The high drying temperature
yielded in darker, less green and more yellow mint leaves. When the 38 models
compared according to the statistical values, the rational function model (model-
32) for drying temperatures of 60 and 70C and Modified Henderson Pabis-II
model (model-5) were superior to the others.
