Whey protein powder is manufactured through a multi-step process that begins with the collection of liquid whey, a byproduct of cheese production. This liquid whey undergoes filtration to eliminate fats, carbohydrates, and impurities.
Subsequently, it is concentrated to increase its protein content, reducing its water content. The next step involves drying, where the concentrated whey is either spray-dried or drum-dried, effectively transforming it into a dry, powdered form.
Typically, spray drying is the preferred method, involving the spraying of the liquid into a hot chamber, causing water to evaporate, leaving behind whey protein powder.
Stringent quality control measures are then implemented to ensure the protein powder adheres to industry and regulatory standards, including checks for protein content, flavor, and the absence of contaminants. The outcome is a versatile and high-quality protein source suitable for a range of dietary and fitness requirements.
