The principal objective of this study was to assess the effects of maesil extract on yellow layer cake made with medium and cake flour. After making yellow layer cakes with maesil extract, water activity, hardness, Max G, springiness and crumb color were evaluated. During storage, the Aw of the yellow layer cakes prepared with maesil extract did not retain its consistency. The hardness, Max. G. and springiness of the yellow layer cakes prepared with maesil extract were all lower than that of the controls. With regard to the color of the yellow layer cakes, the L values were reduced, but the a and b values were increased with the addition of maesil extract. The micrographs of the yellow layer cakes prepared with maesil extract evidenced slightly higher porosity than was observed in the controls. This meant that the cake batter prepared with maesil extract could be used to create yellow layer cake with good volume and good quality.

The purpose of this study was to investigate the properties of yellow layer cake with added buckwheat flour. The physical properties of the cake flour with added buckwheat flour were tested by RVA, farinogram, and alveogram, and then, after making the yellow layer cake, the samples were analyzed by rheometer. We found that the pasting temperature decreased with the addition of buckwheat flour in the cake flour, but peak viscosity, holding strength, and final viscosity increased. For the farinogram, the flour containing buckwheat showed increases for consistency and water absorption, but stability was decreased. The $P_{max}$ of the alveogram was not consistent according to the addition of buckwheat flour to the cake flour. The L- and G-values showed decreases, but they were not significant. After making the yellow layer cakes with added buckwheat flour, crumb softness was analyzed with storage for 7 days. The hardness and Max. G of the yellow layer cakes with buckwheat flour increased, and the highest values were after 1 day of storage. However, springness decreased with the addition of buckwheat flour as compared to the control, and showed the highest value at 7 days.

This study was conducted in order to investigate the effects of maesil extract on medium and cake flour using the falling number and RVA tests, as well as farinography, and alveography. The maesil extract were added on the medium and cake flour bases, 3% and 5% each. The falling numbers of the medium and cake flour with maesil extract were increased due to alteration of the protein in the flour. Analysis of the RVA characteristics showed that the addition of maesil extract did not have a significant effect on the initial pasting temperature. Peak viscosity, holding strength, final viscosity, and the breakdown and setback values of the medium flour were not consistent, but those of the cake flour decreased. Farinography demonstrated that the addition of maesil extract decreased water absorption and improved the stability of the medium and cake flour. The characteristics of the alveogram showed that the addition of maesil extract increased the extensibility and swelling index. Based on the experimental data, the processing rheology may be good when using maesil extract to make yellow layer cake.
