If you want to make a soda biscuit, you need to add a pr-sheeter. The characteristics of the biscuits will determine the type of heat transfer (radiation, conduction and convection) which is appropriate at each stage of the baking process. Biscuits with sugar toppings which are melted to a smooth, shiny surface require high intensity flash heat at the end of the oven to fully melt the sugar. In short doughs with very little water, the starch gelatinisation is very limited. If you want to make a hard biscuit, you need 4 sheeting rollers. Aaron is making southern-style biscuits and needs to combine flour and shortening to make the dough. Walker: “Sugar and Sucrose Ester Effects”: University of Nebraska, Kansas State University The protein is mainly gluten, composed of gliadin and glutenin. The physical and chemical changes noted above which form the texture and structure of the biscuit take place in the first half of the oven. They may overlap and interact.

All materials except flour are preparatory mixed in a certain cream mixer. Sugar cracker. Most fats used in biscuit making are melted below blood temperature (36.9°C), and this avoids a waxy mouth feel. The forming, baking, oil spraying, cooling are continuous operations with a high degree of automation. Typical blended vegetable dough fats are solid at ambient temperature and melt over a wide temperature range. This expansion creates a significant increase in volume of the dough piece during baking. When the dough pieces have reached temperatures over 70°C, the structure is well formed and becomes stable although starch gelatinisation may continue until the dough reaches a temperature of 95°C. Doing fermentation Process The fermentation plays important role in the manufacturing biscuit, cookies and all other types of bakery products. Sumnu and others (1999): “Effects of Sugar, Protein and Water Content”, European Food Research Technology, Springer- Verlag It is a disaccharide composed of two monosaccharides, a molecule of glucose joined to a molecule of fructose.
