| dc.description.abstract | The application of duck eggs in making of cake is very limited. It's caused by the egg white foaming and its stability of duck egg lower than chicken egg. This research was designed to study whether egg white foaming and its stability of Tegal ducks egg in different age could be increased with addiig cream of tartar in a given concentration before mixing. This research was held in Poultry Science Division, Department Animal Production and Technology, Faculty of Animal Science, Bogor Agriculture University, from Mei-September 2005. As first treatment were egg age which contained 4 factor levels; frest, 7, 14, 21 days of egg. Second treatment were cream of tzear addition, that also contained 4 facor levels; 0; 0,s; 1,6; 2,4%. Data which is obtained were analyzed by descriptive method. The result showed that storage and adding cream of tartar treatment's affected foaming ability in egg white. In fresh egg, cream of tartar didn't increase more foaming ability. Average of pH egg white is 8,05*0,25. Adding cream of tartar 0,8% could decrease of pH and made highest foaming stability. White egg seven days had highest foaming ability and its stability with addiig cream of tartar 0,8%. Egg white foaming and its stability 14 days got highest with adding cream of tartar 1,6%, but in 21 days cream of tartar didn't make increase foaming ability and its stability. Storage caused increase of pH and must adding more cream of tartar to increase foaming ability and its stability. Adding cream of tartar in 21 days didn't make increase foaming ability and its stability because were decrease of egg quality.
