Abstract
In hazes obtained by storing beer at 0°C. the concentrations of calcium far exceeded those of any other metal, whereas copper and iron were the predominating metals in turbidities formed at higher temperatures. It is concluded that the heavy metals appear in chemical combination with the haze, whereas the calcium is involved more by virtue of concomitant deposition with haze of calcium compounds as a result of either their reduced solubility at low temperatures or their adsorption by the particles of haze.Keywords
