dc.description.abstractPleurotus eryngii (DC.) Quél. is widely recognized for its organoleptic qualities and health benefits, being commercially produced in great extent in Asia, Europe, and North America [1]. Depending on the size of the mushroom industry, an expressive volume (20 to 35% in weight of fresh mushrooms) of bio-residues are often discarded, even though their content in biomolecules is not necessarily compromised [2]. Hence, there are major opportunities to turn these outcomes into high-value products through the recovery of bioactive compounds, such as ergosterol rich extracts. Ergosterol, one of the main sterols in mushrooms, has been reported to be the major contributor in P. eryngii bio-functionalities [2]. In the present work, P. eryngii bio-residues (PER) and intact mushrooms (PEG) were compared for their ergosterol content. Response Surface Methodology (RSM) was applied using heat-assisted extraction methodology. The combined effect of time (10-150 min) and temperature (30-90°C) was performed using a circumscribed central composite design (CCCD), and the response criteria were extraction yield and ergosterol content using HPLC-UV. The global optimum conditions predicted by the model were 112.7 min, 90°C, and 150 min, 61.8°C for PER and PEG, respectively. Under these conditions, 190.14 and 360.58 mg of ergosterol per 100 g of dry weight sample were recovered from PER and PEG, correspondingly. Even though P. eryngii bio-residues presented up to 53% of PEG ergosterol yield, PER offers sustainable and economic advantages. These results confirm the enormous potential of the under-exploited P. eryingii bio-residues as a valuable source of ergosterol-rich extracts.pt_PT
