3.5. Changes in moisture content and hardness during storage
The cookies prepared with wheat and composite flours were
stored for 7 days at room temperature and the changes in moisture
content and hardness were analyzed. After 7 days, the moisture
content of the control wheat flour cookie increased from 2.28 g/
100 g to 3.29 g/100 g, indicating that the cookie absorbed moisture
from the surrounding air (Fig. 2). The increases in moisture content
of the cookies containing white rice (0.3e0.5 g/100 g) and brown
rice flour (0.2e0.3 g/100 g) were lower than that for the control
wheat cookie. However, the cookies containing GBR and heatmoisture
treated GBR flours showed little and no changes in
moisture content during the storage for 7 days (Fig. 2).
