Off-flavour of canned beer.

Bloeck, S.

One aspect of studying the off flavour of canned beer is the analysis of the exterior decoration and coating cans. The isolation procedure for hydrazones and the gas chromatographic identification of nonanal, decanal etc., is described. Condensation of these components on the inner surface of cans as a result of thermal treatment is considered possible.
