ABSTRACT Bitterness is challenging to analyze due the diversity of bitter compounds, variability in sensory perception, and its interplay with other tastes. To address this, we developed an untargeted approach deconvolute taste molecular composition complex plant extracts. We applied our methodology ethanolic extract Swertia chirayita (Roxb.) H.Karst., a known for unique bitterness. Chemical characterization was performed through nuclear magnetic resonance spectroscopy experiments together...
Through the accidental contamination of a gas cylinder H2S, importance polysulfanes for flint, gun powder, and match odors was discovered. The hydrogen disulfane prepared from disulfanediylbis[methyl(diphenyl)silane], its odor descriptor evaluated in phase chromatograph coupled to an olfaction port. occurrence this compound flint pebbles confirmed by analyses after derivatization with pentafluorobromobenzene. sulfane also two dry white Swiss Chasselas wines, sorted large-scale sensory...
The abundance of the European earwig Forficula auricularia L. (Dermaptera, Forficulidae) in vineyards increased considerably over last few years. Although earwigs are omnivorous predators that prey on viticultural pests such as grape moths, they also known to erode berries and transfer fungal spores. Moreover, suspected affect human perception wines both directly by their processing with grapes indirectly contamination clusters faeces. In this study we artificially contaminated F. adults...
Drosophila suzukii is a very polyphagous species that can also tack and develop in great variety of grape cultivars. In Switzerland, the control D. mainly relies on prophylactic measures kaolin, white inert aluminosilicate mineral who's particles stick to leaf surface form physical barrier help reduce ovipositions by pest. Here we present synthesis our recent insights efficacy kaolin against as well chemical sensory properties wines vinified from treated grapes. autumn 2016, (Surround WP®)...
Native to East Asia, the invasive brown marmorated stink bug (Halyomorpha halys) was accidentally introduced into Switzerland around 2004 and is now spreading all over Europe. This pentatomid highly polyphagous attacks vegetables, field tree crops as well soft fruits. Moreover, development stages of H. halys are found in vineyards, suggesting that grapevine also a host plant for this insect. Nonetheless, its actual effects on European wine production unclear. As such, we studied impact...
