How Does a Plant Protein Extruder Work?
From a simplified view, a plant protein extruder is a machine that includes a screw system inside a barrel that exposes biopolymer ingredients (plants) to heat, pressure and moisture, then passes them through a small opening known as a die. The resulting mass is semi-solid and still contains moisture. This is called wet textured vegetable protein. Dry textured vegetable protein is created by passing the product through a dryer.
Unique challenges loom for anyone working to process plant fibers via extrusion. The vast diversity of the products utilized in this industry can pose obstacles when seeking to employ historically proven processing solutions. One of the major impediments to plant protein processing vs. meat processing is the high amount of powder handling that’s required. These powders (for example, whey protein isolate, wheat gluten and soy protein) are organic, thus combustible, meaning there’s an inherent safety issue. Dealing with powders also means potential allergens and the danger of cross-contamination of products.
Other Difficulties in the Plant Protein Extrusion Process:
- Meeting consumer’s expectations regarding taste, texture, etc.
- Introducing new products
- Growing, harvesting and storing ingredients
The Future of Plant-Based Protein Extrusion
The way each specific material reacts during the plant protein extrusion process has required us to be very innovative during the R&D phase to accomplish each customer’s individual goals. Luckily, Bonnot has an in-house lab fully equipped with extrusion machinery where we have conducted countless tests on a variety of plant-based proteins and meat alternatives.
Overall, we’ve seen positive results.
