How is plant based meat made?
Extrusion is one of the main methods of producing plant based meat. It also is one of the most energy efficient means of mass food production available today. Extrusion technology mixes soft ingredients, forms the food, cooks and processes it in a 3-steps process.
In the first step, the protein powders (made from soy, lentils, chickpeas, ...) are premixed to ensure the quality of the final product. Next, the mixture in fed into an extruder, which consists of a barrel with rotating screws. The extruder both forms and cooks the food - typically in mere seconds.
Finally, the product is ready for processing, which can include anything from cutting to grinding or coating. The entire extrusion process is a continuous, controllable, and cost-efficient means of production. That is why many food manufacturers are converting their existing processes to extrusion due to its costs and environmental benefits.
