Protein powder is created by extracting protein from various sources, including plants and animals. The process involves removing naturally occurring components like carbohydrates, fats, and fibers, while sometimes adding supplementary nutrients or sweeteners.
The Protein Powder Making Process: A Step-by-Step Overview
The exact process varies depending on the protein source, but generally involves these steps:
-
Sourcing: Protein is sourced from materials like milk (for whey and casein), eggs, soy, peas, rice, and hemp. [Source: Live Science, Food Insight, Vivo Life]
-
Extraction: The protein is separated from other components. For whey and casein (from milk), enzymes are used to curdle the milk, separating the protein from the liquid. For plant-based proteins, different extraction methods are used, often involving processes like milling and filtration. [Source: Live Science, The Trost Blog]
-
Purification: Further processing removes unwanted elements like fats and carbohydrates, resulting in a more concentrated protein product. [Source: Wicked Protein]
-
Drying: The purified protein is then dried using methods like spray drying, which converts the liquid protein into a fine powder. [Source: The Trost Blog]
-
Processing (Optional): This stage might include adding other ingredients, such as vitamins, minerals, flavorings, and sweeteners. [Source: General knowledge based on product labels]
-
Packaging: The final protein powder is packaged and prepared for sale.
