Volatile Composition, Colour, and Sensory Quality of Spirit-Based Beverages Enriched with Medicinal Fungus and Herbal Extract.

The multicomponent mixtures consisting of herbs and fungi are commonly used for the production of alcoholic beverages with potential health-promoting effects in many Asian countries. The medicinal fungus is one of the most important fungi used for spirit production. Although this fungus affects the aromatic complexity of spirits, only a small number of studies have focused on investigating the influence of on the aromatic profile and colour of spirits.

Chemical composition, antiproliferative and antioxidant activity of differently processed ethanol extracts.

The content of phenolic compounds (TPC) and glucans, as well as the effectiveness of antiproliferative and antioxidant activity of differently processed ethanol extracts were determined and compared. The content of glucans (total, α- and β-) strongly depended on the extraction time and particle size, but only interaction of these parameters influenced the TPC. Gallic acid, quercetin, -cinnamic acid, kaempferol, hesperetin and naringenin were detected in extracts by HPLC-DAD.

Raspberry wine fermentation with suspended and immobilized yeast cells of two strains of Saccharomyces cerevisiae.

The objectives of this study were to assess the differences in fermentative behaviour of two different strains of Saccharomyces cerevisiae (EC1118 and RC212) and to determine the differences in composition and sensory properties of raspberry wines fermented with immobilized and suspended yeast cells of both strains at 15 °C. Analyses of aroma compounds, glycerol, acetic acid and ethanol, as well as the kinetics of fermentation and a sensory evaluation of the wines, were performed. All fermentations with immobilized yeast cells had a shorter lag phase and faster utilization of sugars and ethanol production than those fermented with suspended cells.
