New analytic methods for brewing industry.Peer-reviewed article

G. BASAŘOVÁ, I. ČERNÁ

The authoresses specify conditions required for freezing and sublimation drying in a new Czechoslovak lyophylization plant  UZBL-1. They have also compared  two albumin isolating methods. Salting- out- with ammonium sulphate is not very  efficient. Far better results have been archived with isolation on the preparation CM SEPHADEX. The sorption of albumins ranger from 75 to 80%. The figure refer to acid samples in the pH 3 region and basic ones in the pH 8 region. The sorption of polysaccharides is comparatively very low. The described method of isolation  will be further studied and developed. In the concluding part of the article the principle and design of the AAA 881 automatic analyzer are discussed in detail. The analyzer has been developed in Czechoslovakia and is used there by research institutes of brewing industry.
