R&D applictions for aquafeed extrudates: Laboratory scale testing to determine appropriateness for species and sustainability

by Brabender, Germany

Gluten-free flatbread, omega-3 noodles, chocolate rice, lupine puffs, woodruff licorice, vegan hot dogs? Extruder products are some of the most trendsetting and promising options for product innovations on the market.

There is practically no other process that offers so much potential for entirely reshaping a food matrix. Therefore, practical equipment with extrusion devices are now necessary tools for product developers in the baked goods, pasta, and snack industries.
 


With the TwinLab-F 20/40, Brabender has now introduced its current top model for the R&D laboratory world. We spoke about the background, possible uses, and innovative device features with the application technicians in Brabender's extrusion laboratory, Julian Foerster and Michael Landers. 

Extruded foods — Where is the trend headed?
ML: With extrusion as a modern key technology, new developments for snack products, breakfast cereals, flatbreads, noodle products or confectionery can be prepared at lab scale. Innovative foods are made possible by varying the parameters of screw speed, temperature, and shear during their interaction at extrusion.

JF: At the moment, for example, protein texturisation of plant-based raw materials for the booming market of meat substitute products is in high demand. Laminar structures are created in the product during the wet extrusion with subsequent cooling of the denatured proteins. This meat-like texturing provides sufficient bite and the desired mouth-feel.

Which current challenges from the industry need to be solved in the laboratory?
ML: We need to be able to evaluate the options for the product development process step-by-step in a realistic fashion in the laboratory. For this purpose, we offer our clients technical solutions.

This is because any possible risks of new procedures must be checked out reliably before proceeding to production with them in large quantities. This means that we need recipes and real products, for example, for the sensory test, texture analysis, or color value optimisation during development. The TwinLab opens up a wide field in this regard: Raw materials can be extruded in various geometries in sophisticated process conditions.
