of potato:oil was kept at 1:50 w/v. Frying was carried out
at 180 1C (71 1C) for 3.3 min, the proper time to reach a
final moisture content of 1.7% (wet basis). The slice pairs
were always fried together. Fried chips were removed from
the oil and cooled at room temperature for 5 min, and then
the originally adjoining faces of the samples were photographed.
All experiments were made in triplicate.
