AB A commercial Belgian Pilsner beer was irradiated with 0, 40, 80 and 120 krad of γ-rays from 137Cs. Analysis of the resultant beers showed that analytical data for polyphenolics to a great extent had remained unaffected, that the treatment had no impact upon liability to haze formation, pH, foam stability and levels of dimethyl sulphide, ethyl acetate, isoamyl acetate, and diacetyl. There was an increase in concn. of acetaldehyde, and a small decrease in concn. of iso-α-acids and n-propanol, the changes being roughly proportional to the dosage applied. The sum of the fast and the moderately fast reducing agents increased with increasing irradiation dosages and in the same way the concn. of slow reducing agents diminished. The treatment at the same time led to drastic loss of colour. The flavour of irradiated beer is totally unacceptable, even at the lowest dosages, the odour reminding one of hydrogen sulphide.
