Twin-screw extrusion: A game-changer for whole grain snacks
Twin-screw extrusion has revolutionized the production of healthy whole-grain snacks, offering a flexible tool to create a new palette of delightful and nutritious foods. Unlike traditional whole-grain formulations, which often result in a heavier texture and denser mouthfeel, twin- screw extrusion technology enables the production of crispy, expanded products with an open cell structure. The intermeshing screws of the twin-screw extruder facilitate necessary micro-mixing, while precise temperature and pressure regulation within individual barrel modules ensure market-quality multigrain chips that consumers love. By adjusting ingredient mix and processing parameters such as temperature, pressure, screw speed, and configuration, twin-screw technology can transform up to 100% whole-grain formulas into palatable snacks.
For relevant conferences and workshops regarding food & feed extrusion, visit www.ExtruAfrica.org.za. The next available course is taking place in August 2023, in Kenya. This course will focus on the applications of extrusion for developing countries. It is focused on technical and practical applications of extrusion and presented by international industry expert, Prof Mian Riaz from Texas A&M University.
