Photometric Iodine Value -Diagnostically Conclusive for Predicting Filterability?

摘要

Investigations were targeted at determining whether correlations might exist between filterability of beer and the level of α-glucans. It was found that the sum characteristic photometric iodine value correlates neither with filterability according to Raible (F _(spec)) or Esser (G_(max)) nor with pressure increase in the commercial-scale kieselguhr cartridge filter. Filtration problems arising could be attributed to breakdown products of amylopectin and glycogen.
