Amylase in High-Hydration Pizza Dough: Dose and Crust Control

Pizza dough with long cold fermentation may respond strongly to small amylase changes. Measure the baked crust and stored texture, not only dough rise.

Define the actual pizza target

An eggshell-crisp, thin crust and a softer stored crumb are distinct targets. Alpha-amylase changes available starch fragments and sugars, affecting fermentation and browning. Maltogenic amylase can influence starch retrogradation; the two products should be screened independently first.

A high-hydration dough can become sticky when starch breakdown exceeds the flour and process tolerance. Evaluate handling at opening and bake, not just fermentation volume.

Use a reproducible microdose

When the intended addition is below the reliable mass range of a small scale, make a documented flour or water premix and include the diluent in every control. State dose as mass of formulated enzyme per flour mass, not an ambiguous percentage of the dough.

Hold the cold fermentation duration and temperature fixed across samples. A change in bake temperature or dough maturity can overwhelm a small enzyme effect.

Evaluate baked and stored pizza

Record dough extensibility, oven spring, top and underside colour, crust crispness immediately after bake and toughness after the intended storage. Use blind sensory checks if flavour matters.

Choose the lowest dose that meets the target consistently. A darker crust alone does not establish improved eating quality or reduced staling.

Turn a microdose into a repeatable experiment

At very low additions, weigh a larger amount of enzyme into a measured flour or water premix, mix thoroughly, and dose by mass. Prepare a carrier-only control. Log the dilution and express the final dose per kilogram of flour so that a successful trial can be repeated in production.

Test alpha-amylase and maltogenic amylase separately first. A simple two-by-two combination is useful only after the individual effect on dough handling, browning and stored texture is known.

Judge the pizza at the table

Record crust crispness shortly after baking and toughness after the intended hold or reheat. Standardise the oven surface, bake time, ball temperature and dough age; these can obscure subtle enzyme effects in a long cold-fermented dough.

Troubleshooting

If the dough becomes sticky, reduce dose and check flour activity and fermentation length. If colour improves but crust softens, separate amylase and maltogenic trials. If replicated pizzas disagree, standardise opening, bake position and endpoint temperature.

Common questions

Can I add both amylases at once?

Screen each first, then test a small factorial combination if the individual effects justify it.

How should I weigh tiny doses?

Use a measured premix and account for the carrier and dilution in every formulation.
