Materials
Fresh durian (Durio zibetbinus Murr.) of the Mon Thong variety was obtained from a local market. The samples were peeled and the seeds removed from the edible flesh. The initial moisture content of the flesh was approximately 197.7–213.9% dry basis (d.b.), as determined by the AOAC method 934.06 (AOAC,1995), and its total soluble solid content, measured by a refractometer, was in the range of approximately 14–15◦Brix. The fresh durian flesh was sliced to a thickness of 1.5 mm by a slicing machine. Durian chips (sliced flesh) weighing 61 g were used under each experimental condition.
