In recent years, supercritical fluid-based technologies have been used for the production of food particles as well as the extraction. These methods are used in particle generation as well as extraction due to properties of solvent such as having good dissolving and diffusing power, moderable conditions, capability to produce particles with a regular particle size distribution of the solvent and being environmentally friendly. Recently, three different techniques named rapid expansion of supercritical fluid(RESS), supercritical anti solvent application (SAS) and particle formation with gas-saturated solvent (PGSS) are used for particle generation. In this study, a novel system capable of doing subcritical water extraction and particle formation was briefly introduced. The system was based on first hydrothermal extraction of target compound, then transition of saturated extract solution into fine particles at underfiow in hot air assistance. Ganoderma lucidum mushroom was used as working material to investigate process parameters. Also, extract composition and structure were identified. (C) 2016 Elsevier B.V. All rights reserved.
