HVG Germany: Hopfen

 

Advantages of fractionation:

  • No further process step is necessary apart from packing, it is therefore a cost-effective process.
  • Defined, stable product, largely identical with the original hop, produced without the influence of heat.
  • Independent dosage of resin (a) and hop oil in the wort.
  • Flexible brewing technology possible, e.g. mild bitterness and distinctive hop aroma
  • Better use of bitter components due to longer boiling times

 
Xanthohumol products

Problems with xanthohumol

  • Poor solubility in wort and beer
  • Concentration generally < 0.2 ppm

Separate products wise for all possible targets:

  • Beer
  • Soft drinks
  • Food

Dosage of xanthohumol / isoxanthohumol in cold phase:

  • Suitable products exist (production conform to purity law, low in nitrates).
  • Suitable dosage apparatus necessary for continual injection into beer flow. 
  • Corresponding beers tend to be cloudy. Dosage can however be used for controlled formation of clouding.
  • „“Special beer“ with considerably increased xanthohumol and isoxanthohumol values can be created as a cloudy speciality; 
  • Bitter character to be taken into account individually. (purity law with cold dosage?)
