Abstract

Postbiotics are substances released or produced by the metabolic activity of microorganisms, which exert a beneficial effect on the host, directly or indirectly, and may include many different constituents, in which short-chain fatty acids (SCFA) stand out. due to their excellent anti-inflammatory and immunomodulatory properties in combating prevalent intestinal diseases, however, SCFAs have some limitations as they are low molecular weight compounds that have limited clinical use due to unfavorable pharmacokinetics, non-selective pharmacological action, low palatability, and unpleasant odor. The development of colon-specific delivery systems based on nano/microsystems, however, may favor the local selective pharmacological action of these active ingredients, improving their therapeutic efficacy. Traditional techniques frequently used to produce nano/microparticles have many limitations, such as control of the average diameter and morphology, high polydispersity index, need for high temperatures for the drying process compromising the integrity of bioactive compounds, low yield, long processing time, high cost, low drug encapsulation efficiency, by-products, organic solvent residues and surfactants, and compromised stability. To get around these problems, supercritical CO2 (SC-CO2) assisted techniques have been explored for drug delivery due to their advantages such as controlled shape, narrow size distribution of the microparticles, high drug encapsulation efficiency, and treatment of thermolabile bioactive compounds. The present project aims to develop multifunctional systems based on nano-in-microparticles using Supercritical assisted electrospray and Continuous Supercritical Emulsions Extraction for the encapsulation of postbiotics, to be carried out at the University of Salerno, under the supervision of Ph.D. Ernesto Reverchon.
