This paper is a brief review of original basic engineering research in morphological analysis applied to particle characterization which has been conducted during the last 20 years at the University of Iowa, Center for Particulate Material Processing Sciences. The topics discussed include definitions, theory, instrumental and experimental aspects of size, shape and texture measurements of particulate material. 

Industrial food products are more or less complex mixtures, whose properties should be recognized and appreciated by consumers. In the development of a new product, engineers and technical staff must take into consideration its chemical, compositional, structural and textural properties, which are determining factors for the product s marketability. In addition, as in any industry, economic aspects must be considered, to decide if the developed product is to be commercialized or not. 

For process engineering purposes, the type of reactor needed for a specific reaction usually determines the shape and texture of catalytic solid materials, which in turn, may influence inter- and intra-particle transport phenomena effecting catalyst performance. Most frequently, packed-fixed-bed, fiuidized-bed, slurry-phase, and membrane reactors are used, which require different particle and pore sizes, shapes, specific surface areas, crushing and abrasion strengths (e.g. pellets, extrudates, spherical and granular particles, powders). Although these aspects play a vital role in the final preparation process for use of the catalysts in a pilot plant and later on in a commercial process plant, they are not discussed in this monograph, which focuses on the catalytic performance of a...
