Viscoelastic Flow of Plant Protein Melts under High Moisture Extrusion Conditions

Autor: Stirnemann, Eric

Protein is an essential part of our diet and is often consumed in the form of animal products. Raising animals for food emits large amounts of greenhouse gases and is an inefficient way of converting plant protein into food. A less resourceintensive
