This method describes how to determine the moisture content of specialty malt.
Specialty malt intended for use in beer brewing or elsewhere in the food industry
The method describes how to determine the chlorine dioxide content of water photometrically with a cuvette test.
Transformation of chloride solutions in the presence of mercury thiocyanate produces less-dissociated mercury(I) chloride. An equivalent quantity of thiocyanate ions is released simultaneously, forming iron(III) thiocyanate with iron(III) salts. The red hue resulting from the reaction is determined photometrically.
Determination of the concentration of the anions bromide, chloride, fluoride, nitrate, nitrite, oxalate, phosphate and sulfate through ion chromatography
Water, wort, beer, NAB and beverages as well as malt and hops
Separation of bromide, chloride, fluoride, nitrate, nitrite, oxalate, phosphate and sulfate through ion chromatography followed by conductivity detection
This method describes the determination of four hop aroma compounds found in hops and hop products using gas chromatography.
Hops and hop products intended for use in beer brewing or elsewhere in the food industry
The hop oil obtained through steam distillation (refer to links) is dissolved in an organic solvent, separated into its components by means of gas chromatography and determined with a flame ionization detector. The contents are expressed as a percentage of the area of each component compared to the overall area of the peak.
Whole hops intended for use in beer brewing or elsewhere in the food industry
Evaluation of the appearance of hop cones is performed through visual inspection and sensory assessment.
Hops and hop products intended for use in beer brewing or elsewhere in the food industry
A reliable sampling method for whole hops and hop products is a prerequisite for obtaining suitable material for analysis. The effort involved in collecting the sample depends upon how uniform the hop product is.
