Processed food manufacturers live and die by consistency. Whether it is the thickness of a canned soup, the rise of a cake, or the smoothness of a custard, consumers expect the same experience every time. The Rapid Visco Analyser (RVA) gives a fast, objective way to monitor product viscosity, compare formulations, and verify ingredient performance — from incoming raw materials through to the finished product on the shelf. It is used by manufacturers of soups, sauces, dry mixes, and convenience foods — including own-brand, private-label, and contract manufacturers — as well as the ingredient suppliers who support them in formulation development and incoming quality control.

Industry Challenges
 

• Finished product viscosity varies between batches due to raw material inconsistency
• Dry mix formulations (soup mixes, cake mixes, custard powders) are sensitive to ingredient ratios, but the interaction between starch, sugar, and protein is complex to predict
• Dosing errors during manual pre-blending of ingredients can produce intermittent out-of-spec product that is costly to scrap
• Replacing or reformulating thickening systems (e.g., switching from potato to maize starch) needs rapid screening to match target viscosity profiles
• Speed-to-market pressure means less time for pilot-scale trials during new product development

How the RVA Solves These Problems

The RVA simulates the cooking process at bench scale, measuring viscosity development through heating, holding, and cooling. For finished soups and sauces, it provides a rapid QC measurement in as little as 1–5 minutes that correlates directly with perceived thickness and stability. You get an objective number to trend and control, rather than relying on subjective assessments.

For dry mixes — soup mixes, cake mixes, custard powders — the RVA tests the formulation by simulating the cooking process. It reveals how ingredients interact: for example, how sugar competes with flour for water in a cake mix, or how different starch systems compare as thickeners in a soup. You can optimise your formulation at bench scale and compare directly against competitor products.

The RVA is also a powerful tool for catching ingredient dosing errors. If an operator misses or double-doses an ingredient during manual pre-blending, the RVA curve shifts in a predictable, quantifiable way. Testing the blend before cooking begins means you catch the error before it becomes a batch of scrap product.

For reformulation work — whether you are switching starch suppliers, developing a gluten-free alternative, or reducing costs — the RVA lets you rapidly screen ingredient options and match your target viscosity profile without tying up the production line for pilot trials.

The RVA comes with a library of standard methods that can be used as-is for known applications, or as a starting point for developing your own product-specific test profiles.
