From Extruded Strands to "Chicken Chunks"
Semester Project in collaboration with ETH Start-Up Planted
Keywords: Who we are: Planted creates tasty ‘meat’ directly from plants - and skips the animal. Our plant-based meat is sustainable, healthy and cruelty-free. We are an ETH Start-Up in the group of Food Process Engineering.
Plant-based meat analogues are a sustainable and animal friendly alternative to animal meat. Currently, most of these meat analogues are produced using high-moisture extrusion cooking (HMEC), a continuous and scalable process involving heat, pressure and shear. In this process plant proteins are mixed with water, kneaded and forced through a die to induce fibrillar structures that mimic the structure of animal meat. Despite the increasing demand for such products, few machines are commercially available to further post-process the extruded strands into products. Post-processing is of high importance to achieve high consumer acceptance, by creating structures such as chunks or nuggets.
Historically, the food industry aimed to make defined shapes and clean cuts. However, in the case of our extruded products, we want to achieve shapes that are random in their look yet not too small or too big and cuts that are fuzzy rather than sharp, thus bringing the true look of ‘chicken chunks’ while

The goal of this work is to develop a prototype, that will allow for the small scale production of such chicken chunks. Initial work was performed with UnicornLabs here at ETH, who helped to define a promising solution to this challenge. We have a great and well equipped workshop in our group (Food Processing, ETH) that can assist with electrical and building (metal, plastic) work.
