Water intended for use as an ingredient in the production of beer (brewing liquor) or other foods
Through the addition of solid calcium carbonate to a water sample followed by constant stirring for a period of time, either part of the salt will dissolve or the water will remain unchanged. By examining the sample prior to and after the addition of calcium carbonate, one can quantitatively determine whether it is lime-aggressive or not.
Determination of the sweetener cyclamate using photometry
Suitable for beer-based beverages and NAB
Cyclamate reacts with sodium hypochlorite to form N,N-dichlorocyclohexylamine. The chlorine compounds are isolated through extraction with heptane and are washed free using excess chlorine. The UV absorption is measured at 314 nm.
Determination of neohesperidin dihydrochalcone using HPLC
Suitable for NAB and beer-based beverages
Neohesperidin dihydrochalcone is separated from the matrix by means of reversed phase HPLC and determined through UV detection.
