The moisture content of a food material is defined through the following equation: %Moisture = (mw / msample) � 100 Where mw is the mass of the water and msample is the mass of the sample. Most powders have the capacity to pick-up water and therefore are containing a certain amount of water. Quantification of moisture content is directly affected by drying rate of a food sample. 0000000000 65535 f If we want to compare the nutritive value of feeds that vary in moisture content, the composition of the feed must be expressed on a "dry matter" or moisture … by loss on drying, in which the sample is heated and the weight loss due to evaporation of moisture … Being that water makes up a large percent of most food products, knowing the expected content can help determine the appropriate analysis method. Furthermore, the maximum permissible moisture content in certain products may be governed by legislation (e.g. 0000000000 65535 f Calculating moisture content from wet weight and dry weight Moisture Content of grain is usually determined on wet basis (wb), scientists sometimes use dry basis (db): MCwb= Moisture content wet basis [%] MCdb= Moisture content … The moisture content of food grains and other agricultural products play an important role in maintaining the desirable quality of product. 1 0000000000 65535 f national food regulations). For the dry basis, the amount of water is divided by the dry weight (solids only). Moisture content is used in a wide range of scientific and technical areas, and is expressed as a ratio, which can range from 0 … Water is a major constituent of most food products. 0000000000 65535 f Rapid Moisture Analysis for Foods Optimize processes and deliver consistent quality . 8.
