2.4. Moisture content
Prior to the frying step, the raw potato cylinders were weighed
to determine their initial mass. After the adhered surface oil had
been removed, the potato cylinders were weighed once more and
oven dried at 105 C to constant weight (approximately 24 h). To
determine the amount of moisture evaporated from the cylinders
during frying, the mass balance was solved assuming oil, water,
and dry matter as the only components.
