Microencapsulation of ergosterol and Agaricus bisporus L. extracts by complex coacervation using whey protein and chitosan: Optimization study using response surface methodology

Abstract: In the present work microencapsulation was applied to an ergosterol enriched extract (EEE) from Agaricus bisporus L. and pure ergosterol (PE) using a complex coacervation process. The process was optimized following two steps: (i) using response surface methodology to optimize the conditions of temperature (T, 55 to 95°C), protein-to-chitosan ratio (P/C, 0.5 to 10.5), maximizing yield (Y 1 , %, w/w), efficiency (Y 2 , %, w/w) and load (Y 3 , %, w/w); and (ii) using the dose-response methodology to optimize the… Show more

“…As the GO/PP ratio decreased, the emulsifying effect might be better, but the electrostatic interaction between wall materials (PP and CS) and the core (GO) also became weak, leading to poor protection of the core material and consequently resulting in partial GO leakage during the process of microencapsulation . Another factor to be considered was that high polymer concentration coupled with the crosslinking of TGase led to an increased viscosity and lower mobility of the macromolecules, resulting in a consequent increase in the competition for solvent molecules …”

“…Microemulsion and microencapsulation are usually regarded as effective technologies for preserving beneficial unsaturated fatty acids (UFAs) from oxidative degradation, to prevent undesirable interaction with other components as well as to expand the applications of oils rich in UFAs and other beneficial components . Chitosan (CS) and protein are usually used as wall materials of microcapsules, since protein–polysaccharide complex can result in liquid–liquid phase separation (coacervation) or precipitate‐like products in specific physicochemical conditions (e.g. pH and ionic strength) .…”

“…In spray drying, the high temperature can disrupt the structural organization of the starch granules and facilitate the entry of water resulting in microparticles of high solubility. High values of solubility also were presented in turmeric oleoresin microencapsulated by spray drying using gelatin-collagen (96.8%), maltodextrin/gelatin (84 -98 %) and maltodextrin, gum arabic and modified starch (85.35 -99.25%) (Cano-Higuita, Rudke et al, 2019;Zuanon et al, 2017).…”

“…Anionic and cationic polymers interact with each other to form a polymer-rich phase called “complex coacervate” in equilibrium with the supernatant (Mishra, 2016). Temperature, core/wall material mass ratio, pH, and the mass ratio of the polymers determine the performance of microencapsulation by complex coacervation (Rudke et al., 2019).…”
