Abstract

Cake is a popular food around the world, however, it is considered as unhealthy due to its high fat and sucrose content. To satisfy customers' demand for a low fat and sucrose cake, in this research both sucrose and fat content of the cake were reduced by using rebaudioside A (Reb A; as a natural sucrose replacer) and inulin (as a natural fat replacer) at 0%, 25%, 50%, 75%, and 100%. The water content of different formulation was adjusted to obtain a constant batter viscosity similar to the control (3,757 cP). By reducing sucrose and fat content up to 50%, water activity increased and the cakes became more asymmetrical. However, other physical properties including baking weight loss, height, volume, crust color, and texture were similar to those of the control. Higher levels of replacement (75% and 100%) resulted in remarkable loss of different quality attributes. These samples showed higher water activity and baking loss, lower volume, harder texture, darker color, and highly asymmetrical shape. Thus, successful reduction of both fat and sucrose in cakes is possible by using inulin and Reb A at replacement levels no more than 50%. Practical applications: Customers' demand for healthy and yet tasty and high-quality foods is increasing around the world. Therefore, finding applicable and safe methods to produce such products is of great interest in the food manufacturing to satisfy customers. Health conscious customers avoid consumption of cakes because it contains high sucrose and fat content. Many studies have been performed to reduce either fat or sucrose content, while a few studies are available to show the reduction of both fat and sucrose in the same product. This study indicates the results of an applicable method to reduce fat and sucrose content of cakes simultaneously. Using rebaudioside A (as a natural sucrose replacer) and inulin (as a natural fat replacer) up to 50% of sucrose and fat content of cakes were reduced and the resulting cake had very similar physical properties to the control.
