Xanthohumol (XN), possessing potent physiological activity, is exclusively derived from hops (Humulus lupulus L.) and exhibits high instability. However, its inherent instability often results in degradation during storage, leading to a decline in its activity due to the formation of various...

Foam is one of the important characteristics of beer, including foamability, foam stability and foam texture. Protein Z (PZ) is considered to be an important component of beer foam. In this study, the interaction between PZ and humulinone, a widespread compound in aged hops, and the effect on foam...

In the current context of developing aromatic beers, our study aims at deciphering the chemical characterisation of cones from 39 wild hop genotypes collected in the North of France and replanted in an experimental hop farm, as well as 10 commercial and 3 heirloom varieties, using HS-SPME/GC-MS for ...

Hop cones are one of the main ingredients used in the brewing industry. Slovenia is presenting the 3^rd place in EU and 5^th worldwide in acreage of hop fields. Nowadays, 98% of Slovenian hop fields are planted with hop varieties originating from national breeding program. In breeding program,...

From time to time, there is an interest among Slovenian hop growers for cultivation of foreign varieties as a response of hop merchant's interest. Those varieties have a large yield and good quality in growing areas where they were bred. However, problems may arise when transferring hop varieties...

The choice of the hop variety is one of the key factors that determines the final aroma of beer. During beer production. hop volatile compounds are chemically and biologically transformed to form new compounds that are not significantly present in the hop cones. To understand the complexity of...

Hops are among the most important ingredients in beer that contribute to beer flavor. Consequently, novel types of hops have been bred and widely used worldwide. For example, the Sorachi Ace hop imparts characteristic varietal aromas, including woody, pine-like, citrus, dill-like, and...

Hop (Humulus lupulus L.) is a dioecious perennial wind-pollinated plant. Sex selection is required in the early stages of the breeding program because only ripe female inflorescences are used in the brewing process and because seeded female cones have lower market value. Hop plants reach...

Composting is a process where organic matter is degraded by microbes under aerobic conditions to obtain a stable material that can be used as organic fertilizer. The trend towards more efficient methods of compost production and handling requires a complete understanding of the process, the...

The phenomenon of hop aging is a topic of significance within the realm of botanical studies. The aging process, while commonly associated with various biological entities, extends its influence to hops as well. This investigation aims to elucidate the impact of aging on hops, exploring the...
