  Impact of spraydrying conditions on the particle size of

  mean particle size of – μm and dispersed in water are perceived as smooth and rich. Spiegel (1999) found after microparticulation of WPC with a SSHE that the threshold between a smooth and a slight mealy mouthfeel for MWP lies around a particle size of 20 μm. Sensorial detectability, however, also depends on the food system containing MWP.

  Process Analytical Technology: Application to

  The purpose of this research was to explore the possibility of employing PAT for particle sizing during spray drying with the use of an inline and atline laser diffraction system. Microspheres were made using maltodextrin and modified starch as wall material and size results obtained using PAT compared with those determined with offline laser diffraction and light microscopy.

  The importance of droplet size in spray drying

  For this reason spray drying nozzles are designed to form very fine droplets. They do this by operating at very high pressures and using the high internal energy of the slurry under such pressures to break it apart into a fine spray. Uniformity of droplets. It is also important to ensure that the droplets formed are fairly uniform in size.
