What is a Rapid Visco Analysis. The RVA mimics the cooking process of a cereal when a flour-water suspension is subjected to a heat-hold-cool-hold temperature cycle Chen et al. Rapid Visco Analyzer is a rotational stirring rheometer that measures apparent viscosity of starch-containing suspensions and flourwater mixtures under variable and controlled heating cooking cooling and shear stress conditions.

Due to its reliability repeatability and versatility the RVA is increasingly used to determine the physio- chemical and in particular the pasting properties of cereal starches. Get a quote today. Consistometer in addition to the more recently developed Rapid Visco Analyser RVA are used to study the functional properties of starch.

It has been established in this study that the Rapid Visco Analyser RVA can describe maize hardness irrespective of the RVA profile when used in association with appropriate multivariate data analysis techniques. The application of the Rapid Visco Analyser RVA as a laboratory scale rheological tool for the characterisation of mash viscosity is the subject of this study. The instrument contains international standard methods as well as being dynamic enough for tailor-made customer profiles.

The viscosity reported is the peak viscosity in RVA units centipoise X 10. You can search for similar products in our product directory. Check out our Used Newport Scientific RVA-4 Rapid Visco Analyser for sale.
