Rheological Properties of Starch Suspension

Starch is utilized in a wide variety of contexts, mostly within the food industry, where it serves both the purpose of a thickening agent and a food stabilizer. The ability of starch to form a paste is dependent on a number of parameters, including the chemical structure of starch, the concentration of starch, and the conditions of the paste-making process. Viscosity is an important characteristic that is used in the measurement of the resistance of a fluid or semifluid to flow, and it is influenced by the concentration of starch, the quantity of amylose, and additives such as sugars and lipids. Gel formation in starch is the result of interactions between amylose and amylopectin molecules, and the strength of the gel rises over time due to the recrystallization of amylopectin. Starch's capacity to operate as a gel can be affected by a variety of variables, including the concentration and kind of starch. The discussion focuses mainly on the qualities and attributes of starch, particularly its ability to create a paste, its viscosity, and its gel formation. When it comes to the applications of starch in the food industry, having a general understanding of the substance's rheological qualities is essential. So, the rheological properties of different starch suspension contents are covered in this book chapter.
