Hyperspectral Imaging Technique for Online Monitoring of Meat Quality and Safety. The most significant is the oven temperature. Principle. Effects of alkaline hydrolysis and storage conditions on the biological activity of ostrich egg white. The moisture content of samples taken from each of the eight moisture content lots was determined by oven drying samples at selected temperatures and times. The weight of water is determined by the difference before and after drying the soil by oven dryng method. The moisture content of the eight lots of rice was determined by various standard moisture content determination procedures to establish the actual moisture content of each lot. The procedure in Clause 8, describing how the test pieces are drawn from the lot, is performed at the time of sampling. The moisture content of timber is the quantity of moisture or water contained in it, expressed as a percentage of dry weight of timber. It is the simplest and the most commonly adopted method for the determination of water content. Page 1 of 6 ‘Good Hygiene Practices along the coffee chain’ 1. In this study different method of water content determination of soil sample is discussed and comparison has been done. Moisture content determination of soils using Oven Drying Method ASTM D2216 needs considerable time which may not be feasible on occasions where more rapid results are required.
