Moisture determination in food can be difficult due to the inherent inhomogenity of these materials. In particular, dried salt cod, has an uneven distribution of moisture due to the uneven thickness of the sample. Salt tends to be unevenly distributed; with lower salt content in the thicker loin part of the muscle and a higher salt content on the surface of the material. Sampling of the Abstract: Chocolate is certainly one of the most familiar and commercially successful products made from plant resources. This success has been built on many decades of careful optimization and innovation in the procedures used to transform the complex mixture of

University of California, Department of Food Science and Technology, , Davis, USA Water determination in foods is a deceptively simple theme. Defining the quantity to be measured identifies the inherent complexity. Three separate types of measure may be … Hypobaric drying method is applicable to determine the moisture for labile products such as sugar and monosodium glutamate.3—2010 National Food Safety Standard Determination of Moisture in Foods 1 Scope This standard specifies the method for determination of moisture in foods.1 HCl (HCl): top-grade purity 3.

In theory, moisture content determination is simply a comparison of the amount of water in a product to the mass of everything else in the product. While it is simple in theory, further investigation of moisture content demonstrates that for such a simple concept, it is an extremely complex process to actually obtain reliable results. Moisture Content Measurement When it comes …

Reference methods are of much use to food manufacturers who must comply with legal requirements for the maximum or minimum amount of water present in diverse foods. Up until now, moisture content determination in a drying oven is the established reference method. Values determined by other methods must, therefore, always be referenced against the LoD method in the drying oven. moisture content impacts on price and there are statutory rules for some products governing the maximum permissible moisture content (e.g. as defined by national food regulations).
