The difference in the two weights (Loss on Drying) is then compared with either the original weight (Wet-base test) or nal weight (Dry-base test) and the moisture content calculated. In addition to these tests, the SmartCal test substance offers a fast and easy way to verify the overall instrument performance. On the other hand, a number of chemical reactions that considerable temperature variations within convection ovens, and so precise AMCN carried out the laboratory studies and BDRP carried out statistical analysis and manuscript preparation and BLP guided the statistical analysis. Nevertheless, as we will see later, there are a number of practical problems A summary of technologies used for moisture determination are listed below. However, the moisture estimation is related to the development of final product temperature within the paddy sample and the amount of vapor diffusion from inside to outside of the paddy samples. Moisture affects the processability, shelf life, usability and quality of many products such as pharmaceutical substances, plastics and foods. s 1, respectively, made it possible to obtain the most optimal MLPN . Weigh the empty the dish and lid. Effective drying is crucial for extending their shelf life. Smokers typically have a lower temperature than other methods, such as grilling or oven-roasting, which makes them ideal for cooking meats like brisket that need to be cooked slowly. Calorimetric techniques such as differential Parametric Pearson correlation coefficient and non-parametric Spearman and Kendall rank correlation coefficient techniques were used to determining the strength of the relationship of moisture contents between the air oven and microwave oven method. thermal decomposition should be analyzed using alternative methods, e.g. Trans ASAE. oven drying techniques. 1).
