Cereal Mechanization Guide from C.H.I.P.S.

The RVA Handbook
edited by Graham B. Crosbie

The RVA (Rapid Visco Analyzer) Handbook is just the tool that RVA users’ need. This handbook will prove to be a valuable bench-top resource.

The wide diversity of subject matter ranges from practical instruction on calibration techniques to provision of guidance on the use of the RVA for applications far removed from its original function.

Topics covered include:

  • Principles of operation and experimental techniques
  • Interpretation of RVA curves
  • Grain and grain products
  • Specialty cereal and noncereal starches
  • Extruded products and degree of cook
  • Nonstarch applications–hydrocolloids, protein-rich foods and ingredients, cheese
  • Enzyme methods
  • Calibration and maintenance

This handbook will assist users to review the scope of applications available, and will be a tool to guide users in developing new applications or improving existing ones, and assist those using the RVA to interpret the results of their tests.
