Internally-developed methods and AACC methods for grains and grain milling products:
- AACC 22-08
- AACC 61-02
- AACC 76-21
A slurried sample is taken through a programmed heat-hold-cool cycle while the viscosity is continuously measured. Differences from the Visco-Amylograph include much smaller sample sizes and the ability to program heating and cooling rates that can change much more quickly than the Amylograph.
Information Required by Submitter:
Because each segment of the grain industry uses different sample sizes and temperature profiles, the customer must supply a method reference with the samples. Medallion Labs prefers AACC methods.
The RVA is an empirical viscometer used to measure the pasting properties of grains, starches, and flours. Because each segment of the grain industry uses different sample sizes and temperature profiles, customers must supply a method reference with the samples. The submitter is encouraged to speak to our test specialist to design an appropriate test protocol if there is no specified method.
