### Wafer Sheet Color Distribution Research  
The color of the wafer sheet is influenced by the dough formula (moisture content, amount of reducing carbohydrates and free amino acids, etc.) and the baking condition (time and temperature). The color of the wafer sheet should be uniform, very regular, and not too dark [2; 16; 29]. The color distribution of wafer sheets is one of the key indicators of aesthetic and quality standards in food production and is a critical element that directly affects consumer perception and satisfaction. Color uniformity provides important clues as to the consistency of the production processes, and any defects in production can be indicated by color variations on the surface. Temperature differences during baking, variations in the composition of the dough, and the equipment used are among the factors that significantly affect the distribution of the surface color of the wafer. In particular, a homogeneous color distribution

The strong relationship between color distribution and moisture distribution is one of the most important parameters to consider in this process. The color change on the surface of the wafer sheet is directly related to the moisture evaporation process. A homogeneous coloration on the surface is an indication that the moisture evaporates evenly and that each part of the product is evenly cooked [4,5,9]. In addition, the baking plate material used in production is another critical variable that directly affects the color distribution on the wafer sheet. Different baking plate materials affect the color differences that occur during baking by changing the temperature distribution on the surface according to their thermal conductivity properties. For example, while cast molds conduct heat more homogeneously and provide a balanced color distribution on the surface, materials such as steel may tend to cool faster and disrupt the temperature balance on the surface, which may adversely affect the color uniformity of the product. In addition, factors such as the smoothness of the baking plate surface and the coating material also play a critical role in color uniformity by affecting the heat distribution on the surface. In order to achieve a homogeneous color distribution, physical properties such as thermal conductivity and surface structure should be taken into account when selecting the baking plate material [3,9,29]. Wafer sheet samples were taken from the same wafer-baking plates whose temperatures and thicknesses were measured for color distribution research. The experiments were carried out at two different production rates (23 pcs/min and 31 pcs/min) on wafer sheets taken from the same baking plate numbers. Figure 7 shows the wafer sheets produced at a production rate of 31 pcs/min in baking plates made of GG-25 casting material. From Figure 7, it is clearly seen that there are large color differences between the colors of the wafer sheets produced in baking plates made of the same casting material (GG-25) at a production rate of 31 pcs/min. Figure 8 shows the wafer sheets produced in baking plates made of GG-25 and GJV-350 casting materials at a production speed of 31 pcs/min. From Figure 8, it is clearly seen that the wafer sheets obtained from the baking plates made of GJV-350 casting material have a more homogeneous color distribution than the color of the wafer sheets obtained from the baking plates made of GG-25 casting material. Figures 9 and 10 show the wafer sheets produced from baking plates numbered 1, 10, 17, 30, and 37 (GG-25) and 6, 15, 20, 26, and 43 (GJV-350) at a production rate of 23 pcs/min. From Figures 9 and 10, no significant color difference is observed between the wafer sheets. Figure 7: Wafer sheets produced on GG-25 cast-iron baking plates at a production rate of 31 pcs/min.
