2.9. Water content measurement
Five different samples were used for the measurements. Differences
between groups were evaluated using a two-sample t test. Five grams of
each sample was placed in an aluminum cup (Toyo Aluminum Ekco
Products) and was leveled using a medicine spoon. Following drying
by heating at 135 °C for 120 min, the water content of each sample
was measured using infrared moisture testers (FD-600, FD-620, Kett
Electric Laboratory).
