The influence of extraction parameters on physicochemical properties of special grain brandies with Ganoderma lucidum

Abstract

Ganoderma lucidum is one of the five major medicinal mushrooms. In Asian countries, alcoholic beverages with Ganoderma are traditionally produced and sold in local markets as a symbol of healthy products. The aim of this study was to examine the possibility of producing brandy enhanced with this mushroom and to investigate the influence of extraction parameters (time, concentration) on color, total phenolic content, antioxidant capacity, sensory characteristics and the composition and content of triterpenoid acids within the brandy. HPLC-DAD/ESI-ToF-MS analysis was used to identify triterpenoid acids. In brandy samples, 15 triterpenoid acids were determined, with the total content in the range of 2.63-4.06 mg/100 mg. In these samples, the most commonly detected triterpenoid acid was ganoderic acid A. In our study, the total phenolic content of analyzed samples ranged from 34.07 to 118.1 mg/L GAE. The color and sensory characteristics of analyzed brandies were significantly improved in comparison with samples without G. lucidum. The obtained samples represent an interesting new product for market worldwide with improved antioxidant capacity.
