The Essence of Extrusion

How does grain become light, crispy extruded bread?

In short: water turning to steam and a sudden drop in pressure create the light, porous structure.

From Grain to Crispbread in Six Steps

  1. Cleaning and Milling

    We clean the grain and mill it into grits of the right particle size.

  2. Mixing

    Freshly milled grains are mixed with the rest of the ingredients.

  3. Into the Extruder

    Water is added to the mix, and the screws convey and knead it intensively.

  4. Heat and Pressure

    Heat and pressure are applied to the dough for a short period of time, transforming the starch.

  5. Expansion

    As the pressure drops dramatically on reaching the die, the water turns into steam, and the material expands and turns airy.

  6. Finishing

    The bread is then rolled, sliced, cooled and packed.

What Makes Extrusion Different

  • Airy Structure

    Created by the sudden drop in pressure.

  • Fast Process

    The heat treatment is brief.

  • No Rising Agent Needed

    Neither yeast nor sourdough is needed in the process of extrusion.

The Benefits of Extrusion Technology

Extrusion is a fast, efficient technology that keeps the qualities of the raw materials while producing light, crispy products.

Health

Health-conscious

  • Significant proportions of the raw materials are processed and milled on site, right before production.
  • May help retain more valuable nutrients and make them easier to absorb.
  • Is manufactured without the use of oil or fat.
  • No rising agent or preservatives are used.
  • A light, crispy texture that is easy to digest.

Environment

A more sustainable alternative to conventional baking

  • Efficient, continuous production.
  • Little process loss.
  • Long shelf life, so less food waste.
  • A flat product shape for better pallet use.
  • Fewer unnecessary additives.

Energy

Energy-efficient

  • The heat treatment is brief.
  • Cooking, shaping and puffing in a single process.
  • Solar panels installed by Abonett allow the use of renewable energy.
  • A fast process that is easy to control.
  • Efficient use of energy.
