Transport of hop aroma compounds across Caco-2 monolayers.
Although being reported and used as a sedative remedy for several years, the bioactive principle of hop preparations is still not decisively clarified. Understanding absorption and transformation processes of potential physiologically active constituents is essential to evaluate the likeliness of biological effects on humans. Therefore, single hop aroma compounds as well as digestive transforma...
متن کاملPlant-derived compounds in treatment of leishmaniasis
Leishmaniasis is a neglected public health problem caused by the protozoan species belonging to the genus Leishmania affecting mostly the poor populations of developing countries. The causative organism is transmitted by female sandflies. Cutaneous, mucocutaneous, and visceral clinical manifestations are the most frequent forms of leishmaniasis. Chemotherapy still relies on the use of pentavale...
متن کاملComparison of the odor-active compounds in unhopped beer and beers hopped with different hop varieties.
Odorants comprising the hop aromas of beers were examined. Strongly hopped beers with Saazer, Hersbrucker, and Cascade hops were compared with unhopped beer by gas chromatography-olfactometry (CharmAnalysis) and sensory evaluation. Twenty-seven odorants were revealed as hop-derived, which derived either directly from hops or via metabolization, and 19 components were identified. Of the componen...
متن کاملHop-by-hop quality of service routing
Based on SAMCRA, an improved and exact version of our QoS routing algorithm TAMCRA, we have investigated QoS routing in a hop-by-hop manner because it forms the basis of IP networking as e.g. in OSPF. In particular, we studied ‘hop-by-hop destination based only’ (HbHDBO) QoS routing that ignores the source and previous path history (as in current IP routing). We demonstrate that an exact QoS al...
متن کاملUse of GC-olfactometry to identify the hop aromatic compounds in beer.
This paper describes a sensorial aroma extract dilution analysis (AEDA) approach to the analysis of beer aromas derived from hops. To obtain an extract with an odor representative of the original product, the XAD extraction procedure was applied and the experimental conditions were optimized. The aromagrams of three beers were compared: one brewed without hops, one brewed with Saaz hop pellets,...
