ABSTRACT
Background: In recent years, mushrooms have got tremendous importance because of their potent bioactive component β-glucan. Objectives: This study was carried out to evaluate the effect of microwave treatment on the structural, antioxidant, functional, antimicrobial, antiproliferative, immunomodulatory and antidiabetic properties of β-glucan extracted from three mushroom species; Agaricus bisporus, Pleurotus ostreatus and Coprinus atramentarius. Methods: The structural characterization of the three mushroom β-glucans was performed using attenuated total reflection – Fourier transform infrared spectroscopy (ATR-FTIR). Results: there was shifting of –OH, –CH, C=O and β-linkage as the microwave treatment increased from 30 sec to 120 sec. In a dose dependent manner, the microwave treatment enhanced all related antioxidant properties like DPPH, reducing power, metal chelating ability of ferrous ion, ABTS and inhibition of lipid peroxidation, P<0.05. Except swelling power and viscosity, all the functional properties increased in a dose dependent manner of microwave irradiation. The antibacterial activities of the three mushroom β-glucans against different pathogens were also enhanced with an increase in the microwave treatment from 30 seconds to 120 seconds. The antiproliferative, immunomodulatory and antihyperglycemic activities of the Coprinus β-glucan showed the highest inhibition activities more than Agaricus and Pleurotus β-glucans that increased as the microwave treatment increased from 30 sec to 120 seconds. Conclusion: This research is an effort to concentrate the various nutraceutical properties in relation with microwave treatment so that it can be used in food and pharmaceutical industries.
