Texture measurement: How to get out of a sticky dough situation

Ask any baker what keeps them up at night, and dough stickiness won't be far from the answer. It's one of those deceptively simple-sounding problems that can cascade quickly into real production headaches - cleaning downtime, wasted batches, inconsistent loaves. Getting it under control is less about instinct and more about measurement.

Why stickiness is such a troublesome variable

Dough stickiness sits at the intersection of several interacting factors: hydration levels, mixing time, flour quantity, and enzymatic activity all play a role. Too much water, over-working, or an enzymatic imbalance can tip a dough from workable to unmanageable. The consequences are felt throughout the line - sticky dough builds up on mixers and rounders, demanding extra cleaning and causing unplanned stoppages. But the opposite extreme is just as problematic: a dough that's too dry won't form properly, and the open, even crumb structure that consumers expect simply won't develop.

It's a genuinely delicate balance - enough cohesion to bind the dough layers and prevent large air pockets, but enough structure to hold the product's shape. And it has to be right before bulk preparation begins, not discovered afterwards.

Why earlier testing methods fell short

Historically, measuring dough stickiness objectively was harder than it sounds. Most methods required the dough to be handled and manipulated before testing - which is precisely the problem. Handling introduces rheological changes, and the drier atmospheres typical of QC labs cause further shifts in the sample's properties. By the time the measurement was taken, what was being measured no longer accurately reflected the dough as it existed on the production line.

Given that stickiness is most clearly expressed when dough is subjected to shear, the ideal is to test immediately after mixing, dividing or moulding - with as little disturbance to the sample as possible.

The Warburtons Dough Stickiness System

To address exactly this challenge, the R&D and engineering team at Warburtons collaborated with Stable Micro Systems to develop a purpose-built solution. The result is a sample testing box into which dough can be placed quickly, minimising the cut surface's exposure to the atmosphere. A retaining plate applies slight compression to the sample, and a narrow blade is driven through a slot in the plate to a defined depth - mimicking the shear action that reveals stickiness in practice.

As the blade withdraws, Exponent Connect software calculates two key outputs: the adhesion peak and the adhesion area. The higher the peak and the larger the area, the stickier the dough. The compression phase also yields firmness data - the compression peak and area - giving a fuller picture of the dough's consistency before any bulk preparation takes place.

The system is well suited to high-throughput bakery environments thanks to its speed, ease of cleaning between tests, and the fact that it doesn't require a temperature-controlled environment. It's available in two sizes to accommodate samples of 500g or 900–1000g, and is a Community Registered Design.

The broader picture for dough testing

Stickiness is just one of the rheological properties that matter in dough development. Stable Micro Systems also offers the Dough Inflation System for assessing extensibility and gas-holding capacity - properties that are critical to understanding how a dough will perform during proving and baking. Together, these tools give bakery scientists a much more complete picture of dough behaviour than visual or tactile assessment alone can provide.

For food scientists and R&D teams working on bread, rolls, or any other fermented dough product, early-stage stickiness measurement isn't just a quality control exercise - it's a direct intervention point for reducing waste, protecting line efficiency, and ensuring the finished product hits the mark every time.
