Optimizing the formulation of functional cake with date syrup and inulin

Cake is a favorite snack of the consumerchr('39')s broad spectrum of age, which has high levels of fat and sugar in its formula, which results in high calorie foods. Inulin is one of the best carbohydrate-based fat substitutes. Inulin is characterized by the ability to form microcrystals in water. It is very suitable for the formation of creamy texture and providing a feeling similar to the fat. One of the ways to reduce the sugar intake is the use of fruit juice with a sweet taste. Due to its natural sweetness and distinctive taste, easy digestion and high levels of sugar in various food products, dates have been considered. The aim of this study was to investigate the replacement of sugar with date palm and the replacement of fat with inulin on the physical and chemical properties of oil cake and optimization of formulation in order to produce pericyclic product with reduced fat and lower content of sucrose. In this study sugar cake formulation was replaced in four levels including 0, 20, 40 and 60% with date syrup. The oil was replaced with four levels of 0, 20, 40 and 60% with inulin. Replacing cake oil with inulin, in addition to reduce the textural parameters of the cake, increase the pH of the cake and and brightened the cake crust, while reducing the yellowness of the crust. Optimization results showed that formula sugar up to 19% with date syrup and oil up to 34% can be replaced with inulin.
