    Noodle flour quality - Using multivariate analysis on the RVA curve to predict Viscograph® results

    The pasting properties of flour provide a useful indication of its suitability for making noodles, bread, cakes, batters and other products. Flour pasting quality is now commonly measured using the Rapid Visco Analyser (RVA). Nonetheless many users still require the results to be converted to historical Viscograph® units for trade. Most commonly this is done by simple correlations. However multivariate analysis (MVA) offers a potentially superior method.
