The ongoing protein transitions results in a series of new ingredient and product developments. All these ingredients and product start at the lab. Dedicated up-scaling is required to get these products into the market. The presentation will focus on the up scaling from lab to pilot scale and further to full scale. With along history of up-scaling (plant) protein ingredients and products, we will share examples on how to develop a lab-scale protocol into a successful pilot trial. The focus will be on wet protein extraction from different crops and using different processing steps. The sustainability of the process will be taken into account when designing a process.
