The book "Luhede: Formulation of Multiple Emulsion" by Laura Luhede provides a comprehensive examination of a novel continuous multi-step membrane encapsulation process. It presents a modular setup that utilizes various porous membranes for each emulsification step to sequentially produce a premix, an internal emulsion, and a double emulsion. The author thoroughly discusses the effects of fluid and membrane properties on the quality of the emulsions, which is of great interest to professionals in the field of chemical engineering. This non-fiction book is aimed at readers who want to engage with the latest developments in emulsification technology and offers valuable insights into the optimization of emulsion processes.
