Foam is one of important traits of beer. It also plays an significant role in evaluating beer's quality. Foam protein is the backbone for beer foam and one of crucial factors in determining beer foam production. Meanwhile, beer foam quality was influenced greatly by the foam protein content and quality.
Protein Z and LTP are two key components of beer foam protein. Three different methods of protein separation were compared, and SDS-PAGE was chosen for the further study. The method of quantitative deter...
