This strong correlation indicated that a rapid moisture content determination based on a very high drying temperature and short time (e.g., 200°C and 1 h) might be used to estimate the moisture content attained at l30°C and 20 h. However, since moisture content depended upon oven drying temperature and time, it was necessary to identify a standard oven procedure for estimating the actual moisture content of rough rice. Accordingly, a hypothesis was postulated and investigated that a relationship between standard and apparent moisture contents existed.
