Tenderness was tested in two ways, one subjective and one objective test. The analysis of scores for tenderness indicated that the cakes baked in some ranges were more tender than cakes baked in other ranges. The statistical analysis showed that these results were significant. The judges, as indicated by scores, considered there were still greater differences in tenderness of cakes baked from a cold and from preheated starts, than for cakes baked in different ranges. These results were highly significant, the cakes started in preheated ovens being tenderer than those baked from a cold start. The analysis of data obtained by tensile strength measurements also indicated significant differences in tenderness of cakes baked in dif- REVIEW OF LITERATURE ON ANGEL CAKE 359 ferent ranges and highly significant differences between cakes started in cold and preheated ovens, those started in preheated ovens being more tender. The correlation coefficient between the two methods of testing ten- derness was —.4014, which was significant. This indicates that in general there was agreement in the two methods of testing tenderness. The volumes of cakes varied in the different ranges, the results being significant, i.e., cakes of larger volume were obtained in some ranges than in others. The volumes of cakes baked in preheated ovens were greatest, and the differences were significant. Burke and Niles made angel food cake on the same day of the week throughout the year, from eggs of the same age, produced by the same flock on controlled feed for the duration of the experiment. The quality of the cakes, at first fairly good, decreased to a low in November. After a slight rise in December there was again a decline in January. A notice- able increase in quality occurred in February and March. They state that the egg-white foams during the "low" and ''high" periods seemed to differ in the time required to beat to the stiff stage. During the "low" period the whites seemed much stiffer and less tender than those in the "high" when beaten for the same length of time. They state that perhaps, if the amount of beating were standardized according to some factor other than time for beating, excellent cakes could be made during the "low" months as well as the "high." One cake each week was baked at 350°F. for 45 minutes, and three cakes at 325 °F. for 1 hour. Consistently throughout the year the moisture loss was less and the volume usually noticeably larger for the cakes baked at the higher temperature. The average moisture loss for the year was 11.2 and 9.6 per cent, and the average volume 7.79 and 7.85 cm., respectively, for cakes baked at 325° and 350°F.
