Cool in the desiccator and weigh. Non-uniform moisture distribution is often found in rice storage; therefore, sampling and moisture determination is an important operation to control postharvest loss of grains [6, 10].

The dry content remaining may be termed the total solids (TS). General linear model (GLM) was mainly used to establish the nature of relationship between the variables tested under the comparison (7-Ismail and Alyahya [7]). Highest total ash content of 1.125 % was obtained in yellow-fleshed sweet potato using oven drying while the least total ash content of 0.735 % was recorded in the white-fleshed species using Sun drying method. Int J Food Sci Technol. Trans ASAE. The moisture measurement was stopped and sample was discarded if the paddy sample was burnt (roasted or color change among the grains) during the MW moisture determination process.

The drying oven method is a thermogravimetric method (loss on drying) in which the sample is dried for a defined period of time at constant temperature. The moisture content is determined by weighing the sample before and after drying and determining the difference. 2. How are samples heated in the drying oven and in the moisture analyzer? Make sure the package has an airtight seal. Moisture analysis plays a vital role in all areas of the food industry, from goods-in inspection, through quality control, production and storage, to the development of new products.

Therefore, several preliminary studies have been conducted to establish appropriate power setting levels to prevent from non-uniform heat distribution and overheating based on the previous studies [2, 16, 22, 23]. In general, all kinds of samples are suitable for both the drying oven and the halogen moisture analyzer. density, electrical conductivity or refractive index. However, it is acceptable to use a moisture analyzer if you can prove its results are the same as those from the drying oven procedure and are of the same level of accuracy. 1993;26(1):4957. vibration and/or rotation of molecules.
