Effect of drying temperature on the content and composition of hop oils
In terms of content, the paper is aimed at analysing and comparing the quality of fresh green hops and hops dried at two drying temperatures - 55°C (in the traditional manner) and 40°C (using the so-called gentle drying), regarding the maximum ...

Exploration of isoxanthohumol bioconversion from spent hops into 8-prenylnaringenin using resting cells of Eubacterium limosum [PDF]
Hops is an almost unique source of the potent phytoestrogen 8-prenylnaringenin (8-PN). As hops contain only low levels of 8-PN, synthesis may be more attractive than extraction.

Present and future potential of plant-derived products to control arthropods of veterinary and medical significance [PDF]
The use of synthetic pesticides and repellents to target pests of veterinary and medical significance is becoming increasingly problematic. One alternative approach employs the bioactive attributes of plant-derived products (PDPs). These are particularly

The secret of dry hopped beers – review
Dry hopped beers gain their characteristic flavour from hop products purposely added during the cold stage of production. Although the production of these beers has not so broad a tradition in the Czech Republic as for instant in Great Britain or the ...

EVALUATION OF HOPS VII. COMPOSITION OF THE ESSENTIAL OIL OF HOPS [PDF]
Analysis of the essential oils from a large number of hop samples, using a combination of gas-liquid partition chromatography and adsorption chromatography, has shown that the oil content is affected by numerous factors including the variety of hop, the conditions during its growth and the treatment received by the cones after picking. Both over-drying
