The CT3 is a more recently developed Texture Analyzer with all the same capabilities as the QTS-25 but more compact and portable and fitted with a 100g Load Cell. 

Rapid Visco Analyser (RVA; Newport Scientific)

A cooking viscometer, the RVA performs viscosity testing of foods, cereals and starches, and provides rheology properties of the tested materials using multi-cycler heating and cooling.

Used for analysis of:

  • Starch: full starch pasting test in 13 minutes, including native and modified starches.
  • Flour milling and baking: starch quality, gluten quality, amylase activity, weather damage.
  • Grains, tubers, roots: wheat, corn, rice, sorghum, potato, tapioca, sweet potato, arrowroot and sago.
  • Brewing: malting barley, barley storage, Kilned malt, brewing adjuncts.
  • Extruded foods and feeds: degree of cook in snacks, breakfast cereals, animal and aquaculture feeds.
  • Protein quality: wheat gluten, skim milk powder, whey protein concentrate, soy protein.
  • Noodles and pasta: Italian style pasta, Asian white salted and yellow alkaline noodle quality.
