Density measurements check the purity and concentration of a sample and give insight into its composition. The measurement of density is crucial in different industries to ensure quality for both raw materials and finished goods.
21 lis 2012 · Abstract: This review presents the concepts involved in determining the density of foodstuffs, and summarizes the volumetric determination techniques used to calculate true density and apparent density in foodstuffs exposed to the drying process.
18 kwi 2007 · The structure of food material can be characterized by density (apparent and true), porosity, pore size distribution, specific volume, particle density shrinkage, and so on. Among these, density and porosity are the most common structural properties reported in the relevant literature.
It is dedicated to explaining what “density” is, how this parameter is defined and measured, the history of density measurement, the different methods available, and also how to ensure you get the best density result by using the techniques of Good Density Measurement ™.
1 sie 2015 · Density of foods is a physical property that is used to determine quality of foods and many-a-times used as a conversion factor to determine volume of foods. There are several measurement techniques for density that involve separately determining mass and volume of the food sample.
In industries like the petrochemical industry the density of a product is a very important characterization number or quality parameter. Norms including the ASTM norm define a certain density for every product, e.g. fuels, lubricating oils, or crude oils.
Applications are to be found in the food industry for almost all the standard techniques for measuring physical quanti ties on-line; this article looks particularly at the way these techniques have been adapted to suit particular conditions.
