Characterization of Wheat Starch Through Rapid Visco Analyzer : Pasting properties of different wheat varieties and how these properties effect the bread and cookies

Starch is the main part of wheat grain and flour. With growing consumer interest for valuable foods, methods to estimate gelatinization and retrogradation actions of starches are main concern.As customer desire for purposeful foods to assess the starch gelatinization and retrogradation performance. Tools are widely used, such as the Rapid Visco Analyzer (RVA) to study the starch gelatinization and retrogradation program in the characteristics of the empirical research. The Rapid Visco Analyzer (RVA) is used in experimental study to analyze the starch properties during the process of gelatinization and retrogradation. RVA is an efficient tool used to study the sticky properties of starch. The use of RVA's in many foods is useful, because it requires complete analysis in 20 minutes or less, ease of operation of the machine, the versatility of the test, and the direct demonstration of starch. In all purpose flour RVA pasting properties measured and found to be similar to those measured by Brabender viscoamylograph.
