Plant protein powders are primarily made by extracting protein from plant-based sources. This involves processing various ingredients, such as pulses, which are legumes like soy, lentils, or chickpeas. There is also an innovative method utilizing mushroom fermentation. The process typically includes combining these ingredients with water, steam, and sometimes oil.
The Manufacturing Process
Here's a breakdown of the typical steps involved:
1. Sourcing Raw Ingredients
- Pulses: Common sources include soy, lentils, and chickpeas.
- Other plant sources: Mushroom fermentation can be used for innovative protein sources.
2. Pre-Mixing
- Ingredients, such as plant proteins, water, steam and/or oil are mixed together. This stage ensures the components are in contact with each other prior to further processing.
3. Extrusion
- The pre-mixed ingredients are then put into an extruder, where they are subjected to further mixing.
4. Processing Methods
- Extraction: Proteins are extracted from plant sources through mechanical or chemical processes.
- Concentration: The extracted protein is then concentrated to increase its protein content.
- Drying: Finally, the protein is dried to create a powder.
Examples of Plant Protein Sources
- Soy: A very common source, often used due to its high protein content and complete amino acid profile.
- Lentils: Offer a good amount of protein and fiber.
- Chickpeas: Another great source that adds a slightly nutty flavor.
- Mushroom Fermentation: This innovative method is a newer approach in the plant protein industry.
Key Steps in Production Table
| Step | Description |
|---|---|
| Sourcing | Obtaining protein-rich plant ingredients, such as soy, lentils, chickpeas, or mushroom fermentation. |
| Pre-mixing | Combining plant sources with water, steam and/or oil to ensure proper contact before further processing. |
| Extrusion | Further mixing of the ingredients happens during the extrusion process. |
| Extraction | Isolating and removing the protein from the plant source. |
| Concentration | Increasing the protein percentage of the extracted substance. |
| Drying | Reducing moisture content to produce a powdered form. |
Practical Insights
- Quality Varies: The nutritional quality and protein content can vary significantly depending on the source and processing methods.
- Taste and Texture: Manufacturers often employ various techniques to improve the taste and texture of plant-based protein powders.
- Additives: Some powders might contain additives such as flavors, sweeteners, or thickeners.
In summary, plant protein powders are made through a multi-step process involving the extraction, concentration, and drying of proteins from plant sources like pulses and mushrooms, often using water, steam and/or oil in the pre-mixing process.
