To determine the moisture loss of drying samples during experiments, okra samples were taken out of the dryer and
weighed at various time intervals, ranging from 10 min at the beginning of the drying to 1hr during the last stage of the
process. The moisture loss of samples was determined with the help of a digital electronic balance having an accuracy of
0.01 g. The experiments were repeated for obtaining more accurate results, after that average values were used. Drying was
continued until the sample reached the desired moisture level (15+0.5%, w.b.).
